Title:
第1冷却サイクルによる冷却により得られたLNGの流れを過冷却するためのプロセス、及び関連した装置
Document Type and Number:
Japanese Patent JP2008536078
Kind Code:
A
Abstract:
In this process, the LNG stream is sub-cooled with a refrigerating fluid in a first heat exchanger. This refrigerating fluid undergoes a closed second refrigeration cycle which is independent of the first cycle. The closed cycle comprises a phase of heating the refrigerating fluid in a second heat exchanger, and a phase of compressing the refrigerating fluid in a compression apparatus to a pressure greater than its critical pressure. It further comprises a phase of cooling the refrigerating fluid originating from the compression apparatus in the second heat exchanger and a phase of dynamically expanding of a proportion of the refrigerating fluid issuing from the second heat exchanger in a turbine. The refrigerating fluid is formed by a mixture of nitrogen-containing fluids.
