EMP for 220,000 BPD Oil Refinery

CE 3

THREE CAREER EPISODES

3. ENVIRONMENTAL MANAGEMENT PLAN FOR THE CIB REFINERY OF

ECOPETROL - WASTE MANAGEMENT COMPONENT

3.1 INTRODUCTION

CE 3.2. This Project (1999-2000) consisted in providing an EIS with instructions, analysis,

procedures and potential projects that could improve the Environmental Performance of the

Petrochemical Complex as a whole, to be implanted by ECOPETROL from 2000 to 2010.

3.2 BACKGROUND

CE 3.3. The Refinery has an area of 254 Ha, having a installed capacity of 225.000 BPD.

Since 1990 the Petrochemical Complex is ruled under a continues improvement Policy

which includes environmental planning principles in agreement with the EMS

(Environmental Management System) of ECOPETROL based upon the International

Standard ISO 14001, which includes compliance with the National Environmental Law.

CE 3.4. The EMP 2000-2010 was granted upon a Public Process that was gained by a pull

of four enterprises, on the head of GEOINGENIERIA, which was in charge of the overall

assessment and Project methodology as well as companies’ coordination and final report

writing.

CE 3.5. The other companies were specialized in three environmental topics: ANTEK in

Waste Water Treatment, ACCA in Gas Emissions Control, Air Quality Monitoring and

Modeling, and WCI-GOLDER in Waste Disposal and Hazardous Substances Management.

I was contracted by GEOINGENIERIA to cooperate with WCI-GOLDER, and build an

Environmental Index to follow up Waste Disposal Management at the CIB. A Flow Chart

CE 3 Alvaro H. Pescador 2

of ECOPETROL, The CIB Refinery and the Companies involved in the EMP 2000-2010

can be seen in Figure 1 of the following page.

CE 3.6 There was a wide variety of Processes at CIB, tailored in agreement with raw oil

characteristics and production requirements. In a general way the operations and processes

performed at CIB Refinery can be grouped in the following way:

Splitting: Oil Splitting by distillation of naftenic, paraphyne and aromatic fractions, with

small quantities of sulphur, nitrogen, oxygen and metals, by differences in the boiling point.

Treatment: This process is done in order to rectify products quality of the fractions

achieved in the previous distillation process. Undesirable elements such as Sulphur,

Nitrogen and Oxygen are removed through hydro-desulfuration and hydrotreatment

processes, chemical treatment (sweet treatment) and acid gas removal.

Oil and Products Management: It involves raw material reception, storage, preparation

(blending) pumping to processes, products storage from processes, and dispatch.

Auxiliary Facilities: The refinery has equipments and processes that are not directly

involved in Hydrocarbon Processes but support the whole operation, such as The Power

Generation Plant, the Hydrogen generation plant, the Sulphuric Acid Plant, The Alkali

Plant, The Sulphur Recuperation Process, The Waste Water Treatment Plant, a Land Field,

and a Biological Treatment Area.

CE 3.10. The Methodology consisted in the use of a systematic approach for revision and

information analysis both in and off site, interviews with operators, direct Plants

inspections, technical and legal documentation review, to determine operational and

potential environmental aspects that affect or may affect the site operation and its influence

area.

CE 3.11. All this information was crossed versus the national and international norms,

already quoted, so it was possible to identify the variations between the observed

procedures and the required, in order to establish the necessary corrections to have

conformity with the standards.

3.3 PERSONAL WORKPLACE ACTIVITY

CE 3.12. In order to capture the field information inside the CIB I designed a format, to

make a waste Generation inventory by Plant, Hazardous Classification, means of handling

and disposal, as the one shown in Appendix 1.

CE 3.13. While WCI-GOLDER focused on catalyses residues final disposal, soil and

lixiviation quality assessment of the land field, as well as TPH (Total Percentage of

Hydrocarbon) tests, to verify the grade of success at the Biological Treatment Area being

both of them final disposal topics as well, I focused on the 42 Plants and Support

Facilities Waste Generation Inventory, Hazardous Substance Classification under

national and international norms, mass balances, and the development of a Waste

Management Indicator.

CE 3.14. By using the Generation Inventory Format, as the one applied to the Cracking

UOP-I Plant, shown in Appendix 1, I got the information for the 42 Processes Plants Listed

on Table 1 (p. 4). Upon this information and by doing the assumptions explained in the

Appendix 2 – Assumptions and Calculation for Mass Balance, I could identify the twenty


most important residues for its amount generation at the CIB Refinery, for a line base

operation of one year. The results are graphically presented in Figures 4 and 5.

CE 3.15. The whole information appears compiled in Appendix 3 – Solid Wastes Inventory

Results. Most important difficulties for doing the inventory was that in many cases there

were not knowledge of the residue’s amount generated in an operational period of time or

during the maintenance, so in these cases the residue was identified at the source generation

and the amount appears as NA (Not Available) in Appendix 3, being impossible to include

them in the mass balance.

CE 3.16. On the other hand, in many cases there was information of the residues amount

only in volume. So it was necessary to calculate theirs density to turn it to mass units. This

was possible to do it with many catalyst by information include it in the MSDS of the

material. For hydrocarbons by using the API gravity, and for some other substances by

using technical literature as explained in Appendix 2 – Assumptions and calculations for

mass balance.

CE 3.17. As can be seen in Figures 4 and 5, most important solid residues generated at CIB

are Sludge (different ranges of blue) with 65% in the total contribution, especially those

coming from the Balance Unit (34%) and the Waste Water Treatment Plant (25%). They

are followed by Catalyst (in the yellow range), especially those coming from the Cracking

Units (21%).

CE 3.18. In agreement to the Appendix 3, a total amount of 14.839 Ton/year of residues are

generated at the CIB Refinery. This quantity maybe bigger, since for many of the identified

residues there were not available data, either of the quantity generated neither the

frequency. Nevertheless the 20 most important residues were identified, having all of them

quantities equal or bigger than 100 Ton/year. In agreement with the interviews to operators

and plant’s Engineers none of the residues which data was not available could reach such

amount.

CE 3.19. As a final conclusion of the mass balance, and knowing the daily charge to the

Refinery (see Appendix 2 at the end), it was possible to estimate the Ratio Residues/Oil

Charge, which was around 1,325 Kg of Residues generated per Ton of Processed Oil.

CE 3.20. But the study, of course, and my contribution, was not limited to do this inventory

and calculations. It was necessary to establish a methodology to identify hazardous

substances and to set recommendations for their management, from the generation source

until the final disposal.


CE 3.21. In order to classify the residues as hazardous or not, I developed the algorithm

presented in Figure 6, Classification of Residues.

CE 3.22. The Criteria used to identify whether a Residue is Hazardous or not is know as

CRETIP: a residue is considered hazardous if it is Corrosive, Reactive, Explosive, Toxic,

Inflammable or Pathogen (EPA, Chapter 40). These criteria are described on Table 2,

Characteristics of Hazardous Substances.

CE 3.23. Finally, I developed the WMI12 (Waste Management Index), as appears on Table

3, in order to follow up the Administration steps in the residue’s management.

maintained in a way that allows reduce health and environmental risks, and avoid possible incompatibilities among different kind or hazardous wastes (Tables 3 and 4, Annex F5, Law 822/98).

Registers must be kept with the entrance date, precedence, departure date and destiny of the stored residues.

The generator must run continual inspections and must document those inspections, as well as observations and corrective actions taken. .

TRANSPORT

1. There must be a certification letter which describes each hazardous wastes delivery. The CIB must keep records with theses certifications.

2. Personal must have knowledge, awareness and training for packing, storing and transportation of the hazardous wastes inside the CIB, as well as to wear adequate Personnel Protective Equipment.

3. The CIB must have a Contingency Plan regarding potential accidents which may happens during transportation of hazardous wastes.

4. The waste generator must contract transportation services only from natural or juridical persons subscribed to the Commercial Chamber, and having a license granted by the environmental authority.

TREATMENT AND FINAL DISPOSAL

1. Biological Treatment Area (For Sludge) 2. By Incineration 3. In High Security Land Fill 4. Other *, (physiochemical, solvent extraction, others) * Just regarding to waste final disposal.

Each stage is qualified as 0 if the waste management is not adequate, or 1 if there is compliance with the norms and procedures synthesized above. An additional point is given if management goes beyond established in ALL stages.

INTERPRETATION OF THE WASTE MANAGEMENT INDEX

WMI = 5: EXCELENT Waste Management goes beyond the established in the procedures

and / or the Colombian environmental law.

WMI = 4: GOOD Waste Management has compliance with the established in the

procedures and in the Colombian environmental law

WMI = 3: REGULAR There is a failure in one of the Stages. When reporting WMI = 3 the

reason must be specified, like this: WMI = 3 G: Not compliance at Generation source. WMI = 3 S: Not compliance at Storing place. WMI = 3 T: Not compliance at Transportation stage. WMI = 3 D: Not compliance at final Disposition.

WMI = 2: DEFICIENT There is a failure in two of the Stages. When reporting WMI = 2, the

reasons must be specified, like this: WMI = 2 S, D : Deficient Waste Management of the Residue due to failures at the

temporal Storage place and in the final Disposition.

WMI = 1: DREADFUL There is a failure in three of the Stages. When reporting WMI = 1, the

reasons must be specified, like this: WMI = 1 G, S, T : Dreadful management of the Residue due to failures at the Generation

source, at the temporal Storage place and during the Transportation stage.

WMI = 0: INEXISTENT There is not a Procedure for the Waste Management of the Residue,

or if there is one as such, there are failures at all the stages.


3.4 SUMMARY

CE 3.24. A total amount of 14.839 Ton/year of residues are generated at the CIB Refinery.

The 20 most important residues were identified by me, having all of them quantities equal

or bigger than 100 Ton/year. As a final conclusion of the mass balance, and knowing the

daily charge to the Refinery, (222.000 BPD) it was possible to estimate the Ratio

Residues/Oil Charge, as 1,325 Kg of Residues generated per Ton of Processed Oil.

CE 3.25. A methodology to identify hazardous substances and to set recommendations for

their management, from the generation source until the final disposal was developed by me,

assessed by WCI, suggested by GEOINGENIERIA to ECOPETROL, Implanted at the CIB

Refinery and then adopted for ECOPETROL in all its operations.

CE 3.26. The classification of the residues as hazardous or not, was explain within the

algorithm of Figure 6, Classification of Residues, and Table 2 Characteristics of Hazardous

Substances, while the way to evaluate the Waste Management at CIB was developed using

an Index to follow up parameters and instructions for each Stage of the Waste

Management.

Comments

In the storing Hopper of Spent Catalyze there were residues of new catalyze mixed with the spent, which contains Nyquil, Vanadium, Sodium, Siliceous and Aluminum residues. Oil filters should be replaced in agreement to a Preventive maintenance Program. It is very IMPORTANT to find a new disposal procedure for the Spent Catalyze due to the Factory that owns the Cement Furnace will stop receiving the residues from the CIB. The HSEQ Management of CIB is looking actually for a place in Iron Nyquil Mine.


APPENDIX 2 – ASSUMTIONS AND CALCULATIONS FOR MASS BALANCE


APPENDIX 2 - ASSUMTIONS AND CALCULATIONS FOR MASS BALANCE

For standardization purposes of Data Collected at field in the 42 Plants and Support

Facilities, conversion factors that allow to homologate the different mass quantity /

frequency units from the field registers as the one shown in Appendix 1, to Ton per year

(Ton / year), were used. The selection of these units (Ton / year) will allow to do a gross

mass balance of the CIB operation, taking one year as a calculation base15.

The following conversion factors were also used:

1 Can = 55 gallons

1 Drum = 55 gallons

1 Barrel = 42 gallons

1 Gallon = 3,785 Liters

1 m3 = 1000 Liters

1 year = 52 weeks

1 year = 12 months

1 month = 30 days

1 Kg = 2.2046 pounds

For many of the calculation specific gravity = 1 was assumed. In the case of hydrocarbons

the density was establish in agreement with the API gravity. For inorganic compounds the

following density values were used16:

Activated Carbon: 2 g/ml

Vanadium Pent oxide 3,357 g/ml

Iron: 7,86 g/ml

For Catalysts stored in cellars which come from the methane and hydro treatment processes

of aromatics and hydro treatment of waxes, a density = 1 gr./ml, was assumed17.

15 One year may be not enough time to accomplish the useful life period of many Catalysts and filtration beds

used in the different processes, but it will allow to establish an average comparative base, that is convenient

to compute ratios such as the quantity of residues generated / refinery charge, and percentage of

contribution by kind of residue upon the same base line: one operational year.

16 PERRY & CHILTON, “Chemical Engineering Handbook”, Vol. 1. México, McGraw-Hill, 5ª ed, 1984, p.

3-6 to 3-55.

17 The density of similar Catalysts from the Cracking Units varies between 0,93 and 0,98 gr./ml.


As an example, we are going to standardize UNIBON´S plant spent Catalyst, which is

known quantity is 755 drums each year and a half:

755 drums 55 gallons 3,785 L 1 m3 1 Ton

------------- x ------------- x ------------ x ---------- x --------- = 105 Ton / year

1,5 years 1 drum 1 gallon 1000 L 1 m3

As can be seen to perform this calculation it has been assume a specific gravity of 1 for the

Catalyst (density = 1 Ton/m3). In a similar way, by using the conversion factors listed

above, as well as substances density values, the standardization process was run for the 42

plants with the aim of having the whole wastes inventory at the CIB in units of the

International System (Ton / year). This also allows to establish the mass balance by plant

and department, taking as a base line one operational year, as appears in the Appendix 3.

It is important to say that those units that were not able to be standardized, as in the case of

spent batteries or empty cans, it appear in units/year (sic) and do not go inside the overall

mass balance. In other cases, when it was known the generation of a residue but there was

not information about the quantity and/or its frequency, it appears NA: Not Available, in

Appendix 3.

On the other hand, it is important to say that in the case of the Hydrogen generation Plan,

the residues were referred to the Hydrogen production, which is 14 MPCD (Millions of

Feet Cubic per Day). To compute the Hydrogen mass it is necessary to use the ideal gases

equation of state. It is assumed that the production measurement is done at normal

conditions of temperature and pressure (298°K and 1 atmosphere).

PV = m R T / M (1)18

Where: P = Gas Pressure (atm)

V = Gas Volume (m3)

m = Gas Mass (Kilograms)

R = Gases Universal Constant: 0,082 atm*m3/(°K*Kmol)

M = Hydrogen Molecular Weight: 2 Kg/Kmol

And therefore:

m = P V M / R T (2)

18 SONNTAG, Richard AND VAN WYLEN, Gordon, “Introduction to Thermodynamics”, Mexico, 1979,

p.73.


Thus:

14 x 106 ft3 (0,3048)3 m3 2 Kg H2 1 Ton

1 atm x -------------- x ---------------- x ----------- x ------------

day 1 ft3 1 Kmol H2 1000 Kg

m = ---------------------------------------------------------------------------

0,082 atm * m3 298 º K 1 año

-------------- x ----------

ºK * Kmol 365 days

m = 11.843 Ton of H2 / year

For establishing general correlation of meaningful solid wastes generation at the Raw

Materials department (sludge from tank’s maintenance, sludge from API Splitters and

sludge from the Waste Water Treatment Plant, mainly) as well as the departments of

Maintenance and Personnel, it was established that in 1999 the Refinery Overall Charge

was of 222 KBPD (Information provided by the HSEQ department at CIB).

To run the mass balance this volume was converted to Ton per year. The average API

gravity of the oil charged to the CIB Refinery has been estimated in 30 °API. So, its density

at 25°C is 0,87 gr/ml (Kern, Op Cit, p. 914, Specific Gravity of Hydrocarbons). Then, we

have:

222000 Barrels 42 gallons 3,785 L 1 m3 365 days 0,87 Ton

------------ x -------------- x ------------ x --------- x ---------- x ------------ =

day 1 Barrel 1 gallon 1000 L 1 year 1 m3

11.206.765 Ton / year

As a final conclusion of the calculation shown in Appendix 3, is possible to estimate that

the amount of solid wastes generation in one operational year at the CIB Refinery is 14.839

Ton, and therefore the Ratio Residues/Oil Charge, is around 1,325 Kg of Residues per Ton

of Processed Oil.
