Title:
FREEZE CONCENTRATION SYSTEM WITH TUBULAR HEAT EXCHANGERS
Document Type and Number:
WIPO Patent Application WO/2012/001706
Kind Code:
A8
Abstract:
An indirect freeze concentration system operating includes a first tube-tube heat exchanger and a second tube-tube heat exchanger. Heat exchange between a selectively supplied feed stream and a low pressure low temperature refrigerant enables a solvent from the feed stream to freeze within the first tube-tube heat exchanger while vaporizing the low pressure low temperature refrigerant. A first compressor receives and compresses the low pressure vapor refrigerant to an intermediate pressure. Heat exchange between a preformed frozen solvent and the intermediate pressure refrigerant within a second tube-tube heat exchanger melts the frozen solvent and partially condensing the intermediate pressure refrigerant. A second compressor receives and compresses the vapours of the partially condensed intermediate pressure refrigerant.
