  • Production equipment and production method of liquefied hydrogen and liquefied natural gas
    Patent number: 10816262
    Abstract: Provided is a production facility for liquefied hydrogen and a liquefied natural gas from a natural gas, including: a first heat exchanger configured to cool a hydrogen gas through heat exchange between the hydrogen gas and a mixed refrigerant for liquefying a natural gas containing a plurality of kinds of refrigerants selected from the group consisting of methane, ethane, propane, and nitrogen; a second heat exchanger configured to cool the mixed refrigerant through heat exchange between the mixed refrigerant and propane; and a third heat exchanger configured to cool the hydrogen gas through heat exchange between the hydrogen gas and a refrigerant containing hydrogen or helium, wherein the first heat exchanger has a precooling temperature of from ?100° C. to ?160° C.
    Type: Grant
    Filed: March 10, 2016

  • NATURAL GAS PROCESSING METHOD
    Publication number: 20080163645
    Abstract: A natural gas processing method includes: a pretreatment process of obtaining a treated natural gas; an NGL recovery process of cooling the treated natural gas obtained in the pretreatment process to recover an NGL product composed of ethane and heavier hydrocarbons and to separate a lean gas; a sales gas production process of compressing a part of the lean gas separated in the NGL recovery process to obtain a high-pressure gas; and a natural gas liquefying process of cooling the high-pressure gas after the high-pressure gas is obtained by compressing the lean gas separated in the NGL recovery process, to thereby obtain the LNG product. In the natural gas processing method, a gas compressor used in the sales gas production process is used as a gas compressor in the natural gas liquefying process.
