BP Berau Ltd. Tangguh LNG Project Operation Manual forSeawater/ Water System

1.

INTRODUCTION The purpose of Seawater Intake (Unit 078) and Water System (Unit 064) is to produce fresh water for the LNG Plant by the desalination of seawater drawn from the seawater supply pump. The Water system is comprised of the following individual systems -

Seawater Intake (Unit 078)

-

Desalinated water system (Unit 064)

-

Utility water system (Unit 064)

-

Potable water system (Unit 064)

-

Demineralized water system (Unit 064)

-

Closed cooling water system (Unit 064)

The water system also supplies potable water and utility water to the support facilities including community area, administration area, upstream operation support area, etc.

2.

BASIS OF DESIGN

2.1

General Desalinated seawater serves as the source, following appropriate treatment, of the utility water, demineralized water and potable water supplies. Utility water is used for make up to the firewater system, cooling water system, and for such general plant uses as pad wash down, equipment cleaning and pressure testing. A demineralized water system is required to supply makeup water to boiler feed water system, makeup water to the AGRU (Acid Gas Removal Unit) for preparation of the acid gas removal solvent and wash water for gas turbine. Demineralized water is produced by means of ion exchange demineralization. Potable water is supplied for drinking purpose as well as for such uses as safety showers and eye wash stations, change room showers, toilets, food preparation etc.
