Title:
ASSOCIATED-WATER CONCENTRATION SYSTEM AND ASSOCIATED-WATER CONCENTRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/008014
Kind Code:
A1
Abstract:
Disclosed is an associated-water concentration system provided with an evaporative concentration device (18) that concentrates associated water discharged from a coal bed along with coal-bed gas. A cooling system that cools said evaporative concentration device (18) comprises: an indirect heat exchanger (28) that cools the evaporative concentration device (18); and a closed loop. Said closed loop comprises either: a cooling-water supply means (38) that draws cooling water (36), used in cooling, from a well (68) or storage pond (34) and supplies said cooling water to the indirect heat exchanger (28); or a waste-hot-water return means (40) that returns post-cooling waste hot water (44) to the well (68) or storage pond (34). This configuration obviates the need for special equipment for treating cooling water (36) after use in the evaporative concentration device (18).
