General contractor will proceed engineering and

design in accordance with the criteria and

guidelines given by the Client /Engineer. When

the project definition phase has been essentially

completed and reviewed by the Client/Engineer, the

bulk of the project's engineering activities are taken

place.

It involves the preparation of detailed drawings,

specifications, procurement of equipment, studies and

analysis, and establishment of detailed project schedules

and cost estimates. The Engineering Dept. or Div. of

HANJUNG has developed its own method of calculation

as to mechanical design of thermal equipments. The

Engineering Dept. works on its own computer package

similar to or same as to SELEK, DESAL for process

design, HEAT TRANSFER RESEARCH INSTITUTE(HTRI),

DISASU, PROPERTY, CHEMICALS MED, VC, VTE and

D/H/F/T-RC computer program originated from U.S.A.

and, if necessary, may require technical help of services

of our licensor group or partner collaborated for job to set

up its own p r o g r a m.

All types of average pressure heat transfer equipment,

pressure vessels and large storage tanks with process

piping can be elaborated according to TEMA, HEI

a nd/or equivalent code used with ASME code a nd /o r

equivalent where applicable.

Furthermore the stress analysis about the tube sheet

and the flange, and the flange to tube sheet junction is

developed according to ASME Code Sec. VIII Div. 2.

Beside HANJUNG has over twenty years of experience in

designing and manufacturing of heat transfer

equipment in all process and of desalination field, we are

up to date with regard to the technological evolution.

The Engineering Department together with the other

department of the company strictly complies with the

prescription of QUALITY ASSURANCE SYSTEM set up in

1976 according to prescription of ASME which has

authorized HANJUNG to stamp its vessels with the "U"

symbol and "N" symbol.

Maximum usage of the vast capabilities of modern

computers is employed to aid the design effort of all

projects. The primary application of computers is

normally associated with design efforts requiring large

amounts of repetitive calculations or calculation solution

methods.

The following applications are typical of the modes of

computer usage on engineering problems.

- Process design computer applications range from

simple curve fitting of data to tray-to-tray calculations

for multi-component, multi-product distillation

columns. In addition to using common library

programs for simple fluid flow and physical properties,

special programs are written to solve unique problems

of heat and material balances or other special

problems not easily tailored to the available programs.

- Electrical design utilizes computer solutions to complex

problems such as faulty analysis and system voltage

drops. More specialized programs include those for

cable tray routing and scheduling, electrical h e a t

tracing design, lighting design, etc.

- Structural and foundation design utilizing computer

methods range from simple spread footings to

three-dimensional frame analysis.

- Computer programs are utilized by the piping engineer

for piping stress analysis, pipe size and weight

calculations. Related programs are used to g e n e r a t e

pipe insulation and painting quantities.

- Pressure vessel design is performed by hand and/or

computer. A related program provides flanges designed

to various design codes.

- Engineering scheduling and progress reporting relative

to manhours mobilized and drawings prepared are

handled by the computer.

- The expertise of other disciplines are available for

consultation. Computer application by these groups

includes solutions to problems in diverse topics such as

dynamic wave analysis, vibration analysis, flare

radiation and center of gravity calculations.

This process is a combination of a thermocom-

pressor and a film multiple effect evaporator. The

multiple effect evaporator has a thin film of seawater

sprayed onto on the outside of the horizontal

arranged heat exchanger tubes.

Evaporation in MED occurs by the exchange of the

latent heat through the heat transfer surface between

condensing vapor on one side and evaporating brine

on the other. Steam introduced into the first, highest

temperature effect is condensed inside tubes, and the

heat thereby released causes a nearly equal amount of

vapor to be evaporated from the feed water on the

outside of the tubes. The vapor produced in the first

effect is, in turn, condensed in the second effect,

again evaporating a portion of the brine feed.

The process is repeated up to last effect from which a

portion of the vapor generated is extracted by steam

jet ejectors (thermo- compressors) which discharge the

combined motive steam and extracted vapor to the

first effect where it provides the heat input to the first

Choosing the optimum system for any location

involves the consideration of many factors, including

the source of water supply, the amount of minerals in

the water, the amount of pure water needed and the

cost of producing it.

Several firms have become specialists in one or two

processes. But to perform the more demanding and

more productive assignment -to select objectively, to

engineer, to construct and to start up whatever kind

of system is best to solve any individual problem-

requires a comprehensive capability. HANJUNG

Engineering capability covers all phases of design and

engineering for plants of many kinds sizes to meet any

specified requirements involving the following process

with the assistance of process engineering from our

Engineering Partners.

Sea Water and Brackish Water

Multi-Stage Flash Type (MSF) Multi-Effect Type (MED)

- Thermal Vapor Compression

- Land Base

- Barge Mounted

Vertical Tube Evaporator (VTE) Reverse Osmosis Type (RO)

- Seawater Reverse Osmosis (SWRO)

- Brackish water Reverse Osmosis (BWRO)

The brine top temperature depends on :

(a) Available steam quality

(b) Scale prevention technique

(c) Brine concentration and nature of

dissolved salts

The last stage temperature depends on :

(a) Cooling water inlet temperature

(b) Absolute pressure maintained in the last

stage by the ejector system

In practice, MSF plants are designed for various gain

ratios (tons of water per tons of steam supplied to

brine heater). A gain ratio of 12 : 1 is the practical

upper limit for this type of plant. Obviously, the

production rate of an MSF palnt is a direct function of

the flashing brine flow and the flash range (brine top

temperature-last stage temperature). Also, in theory,

the actual number of stages os not important for a

given gain ratio with different number of stages.

However, the number of stages determines the total

heat exchange area required for the heat recuperation

section. A large number of stages results in a decrease

of the total heat exchange area required. Because of

this, the maximum number of stages is within

relatively narrow limits for a certain plant. In practice,

however, it can be said that the number of stages

increases at increasing gain ratios, but also depends on

the plant's capacity.

Flash evaporation takes place when a fluid is heated

to a certain temperature and evaporation occurs both

above and below the atmospheric pressure : under

gradual decreasing pressure the phenomenon of

flashing by pressure reduction is called f lash

evaporation.

The principle of operation for multi-stage flash

plants is to heat the seawater(brine) to a certain

temperature, then pass it into a flash chamber where

the pressure is maintained below the equilibrium

pressure corresponding to the temperature at which

the brine enters. Part of this brine flahes into vapor,

and affer passing a demister, this vapor is condensed

on an overhead tube bundle, forming distilled water.

The water is collected in a trough mounted below the

tube bundle and forms the end product fresh water.

As the vapor condenses it also heats the r e c i r c u l a t i n g

brine flowing in the tubes.

Seawater with a salt concentration of 60,000 to

70,000 PPM totally dissolved solids is converted into a

distillate and fresh water with a concentration of only

a few PPM solids : a tremendous reduction in the salt

content. An MSF type plant operate between two

definite temperatures : the brine top temperature

(brine heater outlet temperature) and the last stage

temperature.

effect. The remaining fourth effect vapor is condensed

in a final condenser by transferring heat to seawater.

In coming raw water flows successively through the

tubes of a flash stage and final condenser. All or most

of the heated raw water exiting the final condenser

tubes becomes feed water to the evaporating effects

with the remainder (if any) being discharged. The feed

is treated with an additive to prevent the formation of

alkaline scale on heat transfer surfaces.

The heated feed is sprayed over the outside of the

horizontal evaporator tube bundle in the first effect.

As the feed trickles down through successive rows of

tubes, a portion of it evaporates. The vapor produced

passes through vapor separators which disengage any

entrained brine droplets. Then, the vapor is transferred

via ducting to the tubes of the second effect. This

plant operate at low temperature (Max. 70C) to avoidproblems of scale formation without having to use acid

for operation or for cleaning. This process is available

in any capacity up to 2 MIGD(9000 Ton/Day) and with

a range of performance ratio. (Refer to FIG.1)

Reverse osmosis is a membrane desalination process

utilizing a membrane film which allows water to pass

through it but acts as a barrier to dissolved salts.

When pure water is on one side of a semipermeable

membrane and salt water is on the other, the pure

water diffuses through the membrane into the salt

water as though under pressure. The process is osmosis

and the force causing the flow is osmotic pressure. By

exerting pressure on the salt solution the flow is

reversed and pure water driven out of the salt solution

through the membrane.

In vertical tube evaporation, salt water falls in a thin

film through vertical tubes in a large chamber. As it

falls, it is heated by steam that condenses on the outer

surface of the tubes. This heat exchange converts

some of the salt water in the tubes into steam and

some of the steam around the tubes into fresh water

(comdensate).

Steam generated inside the tubes in the first

chamber flows to the second chamber, and condenses

on the tubes there. The process is repeated in several

chambers. Because each bundle of tubes is called an

"effect", and because a thin film of water falls down

the inside surface of the tubes, the process is

sometimes called "multiple-effect falling-f ilm"

distillation.

Vertical tube evaporators are most cost-effective in

large plants requiring high efficiency. They represent

an advance over older systems in that less heat transfer

surface is required and the water needs to be

circulated only once.
