and 1 no. Portable Silica analyzer on urgent basis for ChemicalLaboratory, DSTPS U#1&2

DSTPS U#1& 2 Chemical Laboratory is now in commissioning stage and no

basic instrument is available in the laboratory till now. An order was placed on M/s BHEL

for supply of some instruments, but no instrument has been supplied till date, which even if

supplied by M/s BHEL, still would not suffice our requirement. We are in need of portable

type instruments to be used at site and in different locations like CWPT, DMPT, DM Plant,

Boiler & Main Steam sample floor instead of within the Laboratory floor. The said

instruments does not come within the purview of M/s BHEL's scope of supply. DMPT & DM

Plant commissioning is completed and PG test is to be done very soon. EDTA cleaning andsteam blowing has been completed successfully. We have managed the situation for testing

during all the activities as mentioned above with the help of our DTPS Chemical Laboratory

&MTPS Chemical Laboratory (Phase-I&II ). Steam dumping, Oil Synchronization and coal

synchronization are the next activities coming up very soon. In 500MW unit steam quality is

to be maintained stringently within the stipulated parameter. So, water conditioning & DM

Plant monitoring is very much essential to get requisite parameter in the boiler water &

steam cycle.

For monitoring this type of parameters sophisticated instrument as

mentioned above are very much essential. The existing O & M plant of MTPS Ph-I&II

(Chemical laboratory) possesses instruments like pH & Conductivity meter (Portable) of M/s

Merck (India) Ltd. make and have shown proven performance over a period of 8 (Eight)

years approximately. Since such type of instruments is normally procured as one time

measure having a life of 10 years. Hence, it is not desirable to go for experimenting with a

different make.

Considering above it is proposed to source standarised on M/s Merck(India)

Ltd. for this instruments only for a period of 2 to 3 years. Total cost involvement was

Rs.367000.00 (Rupees three lac sixty seven thousand) only as per budgetary offer submitted

by M/s Merck India Ltd. Since there is no budget for (O & M), the procurement is proposed

under Capital Budget.

Hence, it is requested to accord administrative approval of the competent

authority for procurement of 1 no. Portable pH meter, 1 no. portable Conductivity meter,1 no. portable turbidity meter & 1 no. portable silica analyzer on single source basis.

Oxygen Analyser on urgent basis for Chemica Laboratory,MTPS Ph-II

MTPS Phase-II Chemical Laboratory is now in commissioning stage and no basic

instrument is available in the laboratory till now for measuring ppb level dissolved oxygen in

primary water circuit of Generator.

An order was placed on M/s BHEL for supply of some instruments, but no instrument has

been supplied till date, which even if supplied by M/s BHEL, still would not suffice our

requirement for these purpose as this instrument does not come within the purview of M/s

BHEL's scope of supply .We are in need of portable type instruments for measuring Dissolve

Oxygen in Primary Water Circuit as and when required in the spot. We have managed thesituation for measuring dissolve oxygen with the help of our existing Chemical Laboratory

(Phase-I), but it is very tough to measure day to day basis .Coal synchronization are the next

activities coming up very soon. Also it is very important that we have to measure Dissolve

Oxygen in dfferent locations as in Economiser Inlet, Hot well and in many other points.

For monitoring this type of parameters sophisticated instrument as mentioned

above are very much essential. The existing O & M plant of MTPS (Chemical laboratory)

possesses instruments like Dissolved Oxygen meter (Portable) of M/s Hach Company make

and have shown proven performance over a period of 3 (Three) years approximately. Since

such type of instruments is normally procured as one time measure having a life of 10 years

then, it is not desirable to go for experimenting with a different make.

Considering above it is proposed to source standarised on M/s Hach Company for

this instruments only for a period of 2 to 3 years. Total cost involvement was about

Rs.7,00,000.00 (Rupees seven lac) only as per budgetary offer submitted by M/s Hach

c) Vide ref. 2 commissiong wing has separately pointed out to M/s L&T to continue supply

of chemicals till PG test, which has not evoked any positive response and M/s L&T hasreplied in that line vide ref: 3.

d) Successful PGTR could not be carried out as M/s L&T has not commissioned the system in

totality and the deficiencies were brought to their notice vide MOM dated 23.06.10 , which

are yet to be rectified fully. DVC has further communicated to M/s L&T that onus for not

conducting successful PGTR lies solely on M/s L&T and as per contaractual clause they are

bound to supply chemicals till successful PGTR, failing which DVC will be compelled to

deduct the cost of chemicals incurred by DVC till PGTR.

e) Since continuity of all the plant activities related to commissioning/ oil

synchronisation/coal synchronisation of U# 1 and other commissioning activities like hydro-

test/Leakage test etc. for U# 2 are dependent on supply of DM water, CW water.Apprehending disruption of all the above activities under letter ref. No.(3) DVC has already

initiated procurement action for chemicals and placed 3 nos. of Purchase Orders for Alum,

Treatment of CW system:

1. The pH of input Raw Water for MTPS Ph-II is around 8.5 and it is notpossible to reduce the ph of CW Make Up water( around 7.6-7.8) only

with alum dosing

2. There is a provision for on-line Chemical Treatment along with Aciddosing of CW water and the work order lies with M/s Ion Exchange(I0Ltd.(order copy enclosed, order awarded by M/s BHEL) but nothing has

been intiated by either M/s BHEL or M/s Ion Exchange.

3. On the above context it is our suggestion from the Chemistry side thatwithout proper Chemical Treatment and acid dosing, CW system should

not run, as it will have a tremendous negative Impact on condenser

tubes in future.

It is our past experience from U# 4 of MTPS Ph-I, the negative

impact of condenser tubes occurs due to the situation as mentioned

above.4. It is hereby requested to consider the above points prior to put service

Sub: Proposal for procurement of 1 no. portable Coulumetric KF tritrator/

Titroline KF Tritrator on urgent basis for Chemica Laboratory, MTPS Ph-II

MTPS Phase-II Chemical Laboratory is now in commissioning stage and no basic

instrument is available in the laboratory till now for measuring low level moisture content in

different oil samples which is very essential to measure frequently.

An order was placed on M/s BHEL for supply of some instruments, but 3 (Three)

instruments have been supplied till date against the ordered quantity, rest which even if

supplied by M/s BHEL, still would not suffice our requirement for these purpose as this

instrument does not come within the purview of M/s BHEL's scope of supply .We have

managed the situation for measuring low moisture content in oil sample with the help of

our existing Chemical Laboratory (Phase-I), but it is very tough to measure day to day basis.Continuous running of the unit is the next activities coming up very soon.

For monitoring this type of parameters sophisticated instrument as mentioned

above are very much essential. The existing O & M plant of MTPS (Chemical laboratory)

possesses instruments like this have shown proven performance over a period of 3 (Three)

years approximately. M/s NTPC Sripath was purchased this instrument from M/s Merck

Specialities Pvt Ltd vide P.O. No. 4200032000-M26-10-09 dated 12.01.2010 (P.O. copy

enclosed). Since such type of instruments is normally procured as one time measure having

a life of 7 years then, it is not desirable to go for experimenting with a different make.

Considering above it is proposed to source standarised on M/s s Merck Specialities

Pvt Ltd for this instruments only for a period of 2 to 3 years. Total cost involvement was

about Rs.4,10, 000/- (Rupees four lac ten thousand) only as per budgetary offer submitted

by M/s Merck . Since there is no budget for (O & M), the procurement is proposed under

NON EPC Sl.No.6 in Contigency budget expenditure vide sanction order No. EDCON/

Sub : Administrative approval for procurement of Inhibited Sulphamic

Acid to be used for on-line condenser cleaning of unit #4,MTPS.

Unit # 4 is running with high differential pressure of cooling water of condenser.

Back pressure of condenser is 0.13kg/cm2

at full load. The value is high with respect to this

winter season. We have physically checked the condition of condenser tubes along with the

maintenance people during last shut down of the unit. The scale thickness was found to be

about 1.0 mm particularly in the upper part of the condenser. But there was no appreciable

scale in the lower half of the condenser. In the coming summer, back pressure is expected to

reach the limiting value for which load of unit #4 may be affected. In this situation, it is

preferable to go for off-load acid cleaning of condenser tubes which are deposited with

some scales. Since, there is no programme of long shut down of the unit in near future it isnot possible to go for off-load acid cleaning of this unit which requires about one months

time for completion. Now, only way left is on-load acid cleaning for which no shut down of

the unit is required. It will not be out of place to mention that it has already been decided

in the daily morning meeting on 24.11.08 to go for on-line acid cleaning of condenser

tubes using M/s DMCC make inhibited Sulphamic acid.(Copy enclosed)

Hence, it is proposed to go for on-line acid cleaning of condenser tubes using

Inhibited Sulphamic acid of M/s Dharamsi Morarjee make as it has a proven performance

of yielding better results in previous occasions on various units of MTPS . In addition to this

the acid is available in inhibited condition ie homogeneity of acid solution with inhibitor can

easily be maintained and inhibitor will protect the parent metal from acid corrosion. Total

materials (Inhibited Sulphamic acid, G.P.Grade) to be required is about 40 MT. Estimated

price for 40 MT of acid is Rs 20.0 Lacs (Budgetary offer for 40MT of sulphamic acid is

Sub:- Administrative approval for Annual operation & maintenance

contract of Chlorination Plant of U# 1,2&3 in Water TreatmentPlant, MTPS (round the clock).

Round the clock chlorination is very much essential to arrest biological

growth as well as to kill micro-organism in the drinking water. The existing

system is to feed bleaching powder round the clock i.e. 3 bags per day (1 bag

in each shift). But, there was no scope for pre-chlorination which is very much

essential for the better health of coagulated water& drinking water. A

proposal was moved through MS-III for Pre & post-chlorination in raw water &

filter water respectively through chlorinator and a new chlorination plant hasalready been commissioned at water treatment plant on 16.04.09 against the

above proposal. The said chlorinator has been commissioned successfully by

M/s Perfect Engineering and they handed over the system. Existing man power

is inadequate to run for round the clock chlorination in raw water & filter

water and there is no departmental infrastructure at MTPS for execution of

the job on continuous basis. M/s Tara construction Company who is presently

executing a contract for chlorination of C.W. water for U# 1,2&3 since

01.08.08 may be considered for the above mentioned job as the jobs are

similar and there is no other party known to us for doing this type ofspecialized job in this zone.

Hence, it is proposed to arrange for obtaining administrative approval

from the competent authority for awarding the job on single tender basis to

M/s Tara Construction Company by inclusion of the subject job on the existing

contract vide order no.MT/CE-1(O&M)/T-57/OS/RP/2792 dated 30.07.2008. The

Sub :-Regarding Analysis report of Drinking Water of MTPS dt. 27.03.09

Analysis report of drinking water has been done by Dy. Director, Public Health

Laboratory, Panchet, DVC in monthly basis. There is some deviations shown in the result as

Residual Chlorine not present in Sl. No.4 & 5 of their result sheet and the above water

sample is bacteriologically unsatisfactory.Now a days Bleaching Powder dosing was done in Filter water tank through day

and night, but the feeding is not responding to the end point of our colony and it is

recorded in Panchet Laboratory results. But within a few days Chlorine gas feeding will be

started very soon in Filter water tank as post chlorination and in Pearsall flume as Pre

chlorination.

Ultimately we hope that after feeding was started the problem in chlorianation

will be solved and we get Residual chlorine at the farthest point of our Colony.

(a) We are having proven performance of Inhibited Sulphamic Acid of M/s

Dharamsi and Morarji Chemical Co. Ltd.make and sulphamic acid of M/s Shree

Sulphamic Chemicals make. During use of Sree Sulphamic Chemicals make

sulphamic acid, performance of Inhibitor of Corroban SSP and Nevamine CAP-

2020 was found satisfactory. Performance of other make sulphamic acid is not

known to us.

(b)Considering the thickness of deposited scale (1.0mm) of the upper part

condenser tube of U # 4, the weight of the scale in terms of the CaCO3 would

be about 11.30 MT. Theoretically about 20.34 MT Sulphamic acid would be

required to remove the said amount of scale and for emergency (Leakage

development during operation and some other reasons) 20% of the total acid

quantity should be kept in hand i.e. 4.07 MT. So, we have to go for purchasing

total quantity of acid i.e. 20.34 + 4.07 = 24.41 MT 25.0 MT of sulphamicacid. [Calculation is given in the Annexure].

(c) Based on our experience and estimation, requirement of inhibited sulphamic

acid/sulphamic acid with inhibitor alongwith specification for conducting the

acid cleaning of condenser tubes ( upper part) of U # 4 are as follows:

Option no. I. - 25 Mt of inhibited sulphamic acid (Purity-97% + 0.5%)

OR

Option no. 2- 25 MT Sulphamic acid (Purity-95% Minimum) + 750Kg.

Nevamine CAP-2020/ 375Kg Coroban SSP (as Inhibitor)

To neutralize the spent acid and wash out the condenser tubes, 2 (Two) other

balance chemicals would be required for complete passivation of the process.

1. Soda Ash- 1.0 MT


36/56

2. Lime- 2.5 MT

Annexure

Estimation of acid for acid cleaning of upper part of condenser U#4

1. No. of tubes in upper part- 9609 nos.

2. Length of the tubes - 7.6 mtrs. = 7600mm.

3. Outer dia of the tubes - 25.4 mm.

4. Thickness - 1.0 mm.

5. Inner dia - 23.4 mm.

6. Scale thickness - 1.0 mm.

7. Volume of scale of 1(One) tube- 3.14 X (11.7 + 10.7) X (11.7-10.7) X 7600

= 3.14 X 7600 X 22.4 X 1

= 534553.6 mm3

8. Total volume of scale - 9609 X 534553.6

109= 5.136 M

3

9. Weight of Scale (as CaCO3) = 5.136 X 2.2

= 11.299 MT 11.30 MT

10. Amount of acid will be required to remove 11.3 MT of scale = 11.30 X 1.8

= 20.34 MT

11. Amount of acid to be kept in hand in excess 20% of 20.34 MT = 4.07 MT

12. So total amount of acid to be arranged 20.34 + 4.07 = 24.41 MT 25 MT

of that we do not get appropriate running hour of the exchanger and

running hours also decreased from 35 hrs to 22hrs(average) .

2. SAC-A :- The differential pressure always persists above the limit and its

running hours has also decreased from 35hrs to 25hrs(average).

3. SAC-C- The life of the exchanger has decreased from 35hrs to

27hrs(average)

4. SAC-D- The life of the exchanger between the regeneration is from 35hrsto 28 hrs (average)

Hence, we propose to do the following jobs for betterment of life of the DM Plant of U#

1,2&3 :-

1. SAC-B- Total resins from the shell is to be replaced by new resins.(about

13000Ltrs resins). Total Distributor (both upper & Lower portion of the

shell) including nozzles to be checked and if required damaged portion to

be replaced by new one.

2. SAC-A- Some fines of resins to be replaced by old resins collected from

Present stock of Ferric alum Slab is 175 MT. With this stock of Alum it is possible to

cater the demand of U# 1 to 6 and ETP for 30 days only. The total supply of materials against last P.O has

already been received. A fresh proposal for procurement of 1000 MT Ferric alum on OTE basis has been

initiated in the month of May09 which is in process in technical section. It will take some more time to finalise

the contract. It is being observed from the consumption pattern that our present stock and the procurement

lead time will not match; especially in view of rainy season, bulk consumption of alum will increase in this

period due to very high turbidity of raw water. Discontinuation of required alum dosing will be a cause of high

boiler water silica.

In the above circumstances it will be prudent to procure 300MT of ferric alum slab by placing a

repeat P.O. on M/s M.S. Chemical Industries against P.O. No. MT/CE/T-57/OS/Chem lab/SRP/2008-09/2826
