Abstract
The present invention concerns a method and a system for cooling of a gas product. The system comprises a feed line (1a) for feeding gas product to the system and a storage (1) for liquefied gas product. The storage (1) is connected to the feed line (1a). The system also comprises a cooling circuit for indirect cooling of gas product flowing through the feed line (1a) to the storage (1), wherein the cooling circuit includes the gas product as a coolant and wherein the gas product may be a petroleum gas or ammonia.
Claims16
A system for cooling of a gas product, the system comprising:
- a feed line for feeding a gas product to the system;
- a storage comprising the liquefied gas product, wherein the storage is connected to the feed line;
- and
- a cooling circuit for indirect cooling of gas product flowing through the feed line to the storage;
- wherein the cooling circuit includes the gas product as a coolant and wherein the gas product comprises petroleum gas or ammonia;
- wherein the cooling circuit further includes:
- a heat exchanger for vaporizing condensed coolant and for cooling the gas product flowing into the storage, wherein the heat exchanger is connected to the feed line;
- a compressor for compressing vaporized coolant exiting the heat exchanger, wherein an inlet side of the compressor is connected to the heat exchanger by a first flow line;
- a second heat exchanger, for condensing of compressed coolant exiting the compressor, wherein an outlet side of the compressor is connected to the second heat exchanger by a second flow line;
- and
- an expansion valve for expansion cooling of condensed coolant exiting the second heat exchanger, wherein the expansion valve is connected to the second heat exchanger by a third flow line, and connected to an inlet of the heat exchanger by a fourth flow line.
A method of cooling of a gas product, the method comprising providing a feed flow of gas product to a storage and cooling the feed flow in a heat exchanger, before the feed flow enters the storage;
- wherein:
- cooling is regulated by an indirect vapor-compression cooling cycle utilizing the gas product as a coolant;
- and
- the feed flow includes liquefied ammonia or liquefied petroleum gas.
