Instruction Manual for Fresh water Genera tor

Type JWP-26-C80/100

System description

1.0 WORKING PRINCIPLE

The combined brrnetarr ejector driven by the ejector pump creates a vacuum in the system in order to lower the evaporation temperature of the feedwater.

The feedwater is introduced into the evaporator section through an ofifice, and is distributed into every second plate channel (evaporation channels).

The hot water is distributed into the remaining channels, thus transferring its heat to the feedwater in the evaporation channels.

~av in i reached boiling temperature - which is lower than at atmospheric pressure - the feed water undergoes a partial evaporation, and the mixture of generated vapour and brine enters the separator vessel, where the brine is separated from the vapour and extracted by the combined brinelair ejector.

Having passed a demister the vapour enters every second plate channel in the condenser section.

The sea water supplied by the combined cooling/ejector water pump distributes itself into the remaining channels, thus absorbing the heat being transferred from the condensing vapour.

The produced freshwater is extracted by the freshwater pump and led to the freshwater tank.

1 .I FRESHWATER QUALITY

To continuously check the quality of the produced freshwater, a salinometer is provided together with an electrode unit fitted on the freshwater pump delivery side.

If the salinity of the produced freshwater exceeds the chosen maximum value, the dump valve and alarm are activated to automatically dump the produced freshwater to the bilge.


Type J WP-26- C8OA 00

If there are no special requirements from the authorities, the produced freshwater can be used directly as drinking water.

MAIN COMPONENTS

The freshwater generator consists of the following components

1. Evaporator section

The evaporator section consists of a plate heat exchanger and is enclosed in the separator vessel.

2. Separator vessel

The separator separates the brine from the vapour

3. Condenser section

Just like the evaporator section the condenser section consists of a plate heat exchanger enclosed in the separator vessel.

4. Combined brinelair ejector

The ejector extracts brine and incondensable gases from the separator vessel.

5. Ejector pump

Normally, the ejector pump is delivered by Alfa Laval, and the ejector pump is a single-stage centrifugal pump.

This pump supplies the condenser with sea water and the brinelair ejector with jet water as well as feed water for evaporation.

Freshwater pump

The freshwater pump is a single-stage centrifugal pump.

The freshwater pump extracts the produced freshwater from the condenser, and pumps the water to the freshwater tank.


Type J WP-26-C80A 00

Salinometer

The salinometer continuously checks the salinity of the produced water The alarm set point is adjustable.

Control panel

Normally, the control panel is delivered by Alfa Laval. It contains motor starters, running lights, salinometer, contacts for remote alarm and is prepared for startlstop.


Type J WP-26- C8O/lOO

Operating instructions

Freshwater must not be produced from polluted water, as the produced water will be unsuitable for human consumption.

1.0 STARTING AND STOPPING PROCEDURE

Before starting up please observe instructions for feedwater treatment, see "Chemical dosing of scale control chemicals"

Please refer to PI-diagram (see "FWG Order Specification").

1.1 STARTING

1. Open valves on the suction and discharge side of the ejector pump PU-SC-01.

2. Open overboard valve for combined brinelair ejector.

3. Close air screw VA-E1-01 on the separator.



4. Start ejector pump PU-SC-01 to create a vacuum of min. - 90%. Pressure at combined brine/air eiector inlet minimum 300 kPa (3.0 kp/

Back pressure at combined brine/air ejector outlet maximum __ 60 kPa -- - (0.6 kp/cm2.). -/

1 .I .I Evaporation

When there is a minimum of 90 % vacuum (after maximum 10 minutes), - 5. Open valve for feedwater treatment, if any.

6. Open hot water inlet and outlet valves.

7. Start hot water supply to distiller by adjusting bypass valve step-wise 1 O°C, until the desired jacket water temperature is reached.

The boiling temperature now rises, while the obtained vacuum drops to approx. 85%.

This indicates that evaporation has started.

1 .I .2 Condensation

After approx. 3 minutes the boiling temperature will drop again, and normal vacuum is re-established.

8. Open valve to freshwater tank.

9. Switch on salinometer

10. Start freshwater pump PU-FR-01/PU-FR-02 .


Type J WP-26-C80/lOO

NOTE:

The freshwater pump pressure must be between 1 20 and 1 60 kPa (1.2 - 1.6 kp/cm2.).

After starting the freshwater pump the flow sight glass must be empty.

If water remains in the flow sight glass, please refer to "Trouble shooting"

1.2 ADJUSTMENT OF HOT WATER FLOW

Please refer to "FWG Order Specification" for specified hot water flow.

In order to obtain the specified flow of hot water, it is necessary to adjust the bypass valve until desired flow is achieved.



The flow can be calculated as follows:

MJw = KJw x cap.m3/24h = m3/h

At JW Where:

M~~ = Flow of hot water in one hour

K~~ = Constant=25.6 for 1. stage freshwater generator

K~~ = Constant=15.52 for 2. stage freshwater generator

AtJW = Difference in temperature hot water in and out.

Cap. m3/24h = Freshwater production in 24 hours, i.e. production in 5 min.times 288.

Example: cap. m3/24h = 15m3

1.3 ADJUSTMENT OF SEA COOLING WATER

The sea cooling water flow is correct, when the pressure at the inlet of the combined aidbrine ejector is between 300 and 400 kPa (3.0 - 4.0 kp/cm2.).

1.4 STOPPING THE PLANT

1. Stop hot water supply to distiller.

2. Close valve for feedwater treatment, if any.

Maintenance

1.0 WHY YOU NEED TO PERFORM REGULAR MAINTENANCE DUTIES

Regular maintenance of the plant will improve performance and availability.

The maintenance schedule on the following pages will tell you how often service should be performed on the main components.

As the actual operating conditions of the plant are of major influence on the life time, the overhaul dates are not obligatory but only recommended intervals.

When the plant has been in operation for a longer period of time and experience has been established as to the actual performance, it will be possible to adapt the maintenance schedule.

For service on minor components please refer to component instructions

1.2 MAINTENANCE OF SEPARATOR VESSEL

The front cover and the pressure plates for the heat exchanger sections (evaporator and condenser) are made of stainless steel with a special chemical treatment. This treatment will re-establish normal surface oxidation after work-up at the factory. The preparation is a natural protection of the stainless steel.

To preserve this natural protection DO NOT scrape or scratch the inside surface of the front cover.

Whenever the separator vessel is opened,

check that the anodes are functioning

If the anodes are not functioning and/or worn, replace them.

NOTE!

If the unit is stopped for a longer period than 14 days,

open front covers and clean unit inside with freshwater.

Let the unit dry out completely, before closing covers.

1.3 MAINTENANCE OF EVAPORATOR SECTION

Clean evaporator as follows:

1. Remove bolts in front cover, and open.



2. Loosen the 2 nuts for P-16 distiller 4 nuts for P-26 distiller

in plate stack gradually, so that no nut is carrying the entire load alone

3. Remove plate stack.

10. When the condenser section is found to be tight, close front cover and tighten bolts.

11. Retighten, when vacuum has been re-established.

1.5 RENEWAL OF PLATE HEAT EXCHANGER GASKETS

1.5.1 Removal of old gaskets

Pull the old gaskets out of groove.

If the gasket cannot come off directly, heat the back of the gasket groove with a hot-air blower or butane gas burner.

Pay attention not to overheat the plates.

You will obtain a suitable temperature, if the flame is held 10 to 15 cm behind the plate.

DO NOT use acetylene gas

1.5.2 Cleaning

Charred or loose glue and rubber remains must be removed, e.g. using a rotating stainless steel brush. The width should be adapted (040-50 mm, width 8-10 mm). Thin layers of glue which are difficult to remove, may remain.

Clean the gasket groove with a clean cloth, dipped in a solvent (acetone, methyl ethyl ketone, trichlorethylene etc.).



Be careful when handling these solvents, as they may be hazardous to your health. Observe suppliers' instructions.

Gaskets, that have only loosened slightly, can be glued on. Clean gasket groove carefully with a sharp tool. Then clean the loose part of the gasket with emery cloth or sandpaper. Then clean groove and gasket with a solvent, and glue.

1.5.3 Preparation of new gaskets

Dry new gaskets with a clean cloth that has been slightly moistened with a solvent.

1.5.4 Fitting new gaskets

1. Apply a thin layer of glue to both gasket and groove.

2. Let the glue dry for 10-1 5 minutes.

3. Fit new gasket into groove.

Gaskets may sometimes be slightly short or long.

Short gaskets should be stretched before being fitted into the groove.

Long gaskets should be fitted into the grooves at the plate ends first and then gradually be pushed into the towards the middle.

If necessary, tape gasket into groove.



Chemical dosing of scale control chemicals

1.0 PREVENTION OF SCALING

During the evaporation of sea water there is always a risk of scaling on the heating surfaces. This will lead to a reduction of the K-values of the heating surface and decreasing freshwater production and reduction of plant efficiency.

In order to effectively prevent scaling the operators must be aware of the factors influencing the scale formation:

1.1 FEED WATER RATIO

The feedwater ratio is an extremely important factor. It is defined by the relationship between the feedwater amount fed into the plant and the produced amount of freshwater.

If the feedwater ratio is reduced, the concentration will rise in the plant subsequently resulting in scale formations.

Two things may shift the feedwater ratio: first of all direct adjustment of the feedwater system, and secondly exceeding the maximum freshwater production laid out for the plant. The operators must observe the following rules at all times.

DO NOT adjust feedwater system.



1.2 CHEMICALDOSAGE

In order to control scale formations on the heating surfaces and continuously ensure long operation periods without acid cleaning the plant, it is absolutely necessary to dose scale control additives to the feedwater. The operators must follow the instructions for chemical dosing given by the chemical supplier carefully.

If the distiller is operated at boiling temperatures above 45°C without chemicals, frequent cleaning of the evaporator will be necessary.

We recommend that you do not operate the freshwater distiller without recommended chemical dosage at boiling temperatures above 45°C.

1.2.1 Scale inhibitor dosage equipment for feed water

Please refer to drawing, see "FWG Order Specification"

When adding chemicals mix thoroughly to ensure a homogenous blend of chemicals and water.

Use a fully soluble scale inhibitor, e.g. on polymere basis. The following products can be recommended:

NALFLEET Evaporator treatment 9-91 3

AMEROYAL EVAPORATOR TREATMENT

HEXAMETHAPHOSPHATE

1. Mix the required quantity for 24 hours operation in the tank according to maker's instructions.



Adjust flowmeter to cover the maximum freshwater output from the distiller.

Flush the dosage system regularly.

1.2.2 Safety precautions with the use of chemicals

1. USE eye protection and gloves. Avoid direct skin contact, eye contact or contact with clothes.

2. CLEAN empty containers before disposal.

3. If chemicals are spilled on clothes, rinse with water and dispose off clothes.

4. If chemicals are spilled on the floor, rinse with water and suck remaining chemicals off with sand. Clean the spot immediately afterwards.

5. Scale inhibito~ is hazardous, if consumed in a concentrated solution. If consumed by mistake: IMMEDIATELY SEEK MEDICAL ATTENTION.

6. If eyes get in contact with the chemicals, rinse for at least 20 minutes. IMMEDIATELY SEEK MEDICAL ATTENTION.

Alfa Laval Marine & Power General description Freshwater Generator JW(S)P-26-C80(B)/C100

Doc. No. 9.2.2.1 Edition 96.10

Application

Conversion of seawater into fresh water by vacuum distillation. For drinking, process water, and domestic use on ships and rigs, and in small power stations. Max. salinity 2 ppm.

Capacity

The JW(S)P-26-C80(B)/C100 covers a capacity range from 4 to 33 m3/24h, depending on the heating medium and seawater temperature. The capacities shown below are at a seawater temperature of 32OC.

Heating medium 'C

Working principle

The seawater to be distilled evaporates at a temperature of about 40°C as it passes between the hot plates in the evaporator. This evaporating temperature corresponds to a vacuum of approximately 93OA which is main- tained by the brinelair ejector. The vapours generated pass through a demister where any drops of seawater entrained are removed and fall to the bottom of the distiller chamber. The vapours continue to the condenser where they condense to fresh water as they pass between the cold plates.

Basic Equipment

Titanium plate heat exchanger in evaporator and condenser. Red brass separator and stainless steel demis-

ter, front cover and pressure plates. Seawater pipes in CuNi. The freshwater generator is equipped for jacket water heating and with a combined condenser cooling and ejector water system. Furthermore the freshwater generator is equipped with dump valve, water clock, automatic feed water regulator, combined brinelair ejector, instruments, freshwater pump with electric motor, internal piping and bed frame.
