TH1256A - A process of cooling in a continuous system in which a combination of mixed gases is used in conjunction with the cooling object. - Google Patents

Abstract

This invention is directly related to cooling. And to cause a liquid transition to a current containing mixture Of high methane gas such as natural gas or various synthetic gases, especially This invention is directly related to System of continuous cooling Which led the movement Two processes of cooling are utilized for cooling and the liquidization of the gas stream passed through it.

Claims (7)

1. Process for use in cooling And to liquefy a gas stream containing a high rate of methane mixture with very high pressure, which consists of the following steps: (a) Initial cooling of a gas stream containing a High rate of fiber by using multiple heat switch systems in A refrigeration system that uses only one gas for cooling (b) cools and turns part to liquid. Connect refrigerant gas that has been pressurized mixed gas in succession with heat switch of A single gas refrigeration system (c) separates the gas and liquid received from the mixed gas system, which Through cooling and then apart (d) transformed into a liquid And to cool the gas stream that Methane gas is mixed in. By using several sets of heat switch to With the gas and liquid parts from the mixed gas refrigeration system (e), pressurize the refrigerant from a single gas system. By using multiple (f) air compressors, refrigerant gas from a single gas system is used. Hydrocarbon-free chilled water (g) provides initial pressure on the refrigerant gas from the mixed gas system and cools the refrigerant gas using chilled water. From hydrocarbons (h), cooling during the period of operation to the gas is made. Cooling from mixed gas systems By using refrigerant gas from a single gas system with a heat switch To form a current with a mixture of two (i), it is compressed against the gaseous mixture formed by the mixed gas system. And to cool the refrigerant that has been compressed by using Chilled water without hydrocarbon Before giving additional cooling Fill with refrigerant gas from a single gas system (j). Compress the liquid part from the mixed gas system to high pressure. Equal to the gas-producing part at the (i) step above (k), combine the currents obtained from (i) and (j) together for additional cooling in the steps given in (b). Above 2. Process according to claim 1, where the liquid without high Dorcarbon for use in cooling is naturally cooled water. 3. Process according to claim No. 1, which the refrigerant gas in the system A single gas is a gas of choice from a group containing propane and propylene. 4. Process according to claim 1 or 3 which refrigerant gas From the mixed gas system It is a mix of nitrogen, methane, ethanol and propane. 5. Process according to claim 4 in which the ingredients are ethane Or the propane in the mixture gas has been replaced with ethylene or propylene, respectively. 6. Process according to claim No. 4, which mixed refrigerant gas It could include butane or pentane. 7. Process according to claim 1, in which hydrocarbon-free liquids are used for cooling. Is air with normal temperature (7 claims, 2 pages, 1 picture)
