[Problem] To provide technology for reducing the content of benzene mixed into methane during a treatment for separating natural gas into methane and a C2 or higher heavy component. [Solution] A natural gas treatment method using a natural gas distillation column 17 to separate natural gas into methane and a C2 or higher heavy component, wherein natural gas containing benzene is received from a supply line 106, cooled, and then separated into a gas and a liquid. By decompressing and expanding the gas obtained from the separation and thus lowering the temperature thereof, a gas-liquid mixture is obtained, and the gas-liquid mixture and the gas are introduced into a natural gas distillation column 174 and distilled to discharge methane and a heavy component. A rectification unit 2 separates, from the heavy component, absorption liquid main components which include butane and isopentane and are for absorbing the benzene in the natural gas. Natural gas from a natural gas supply line 101 and an absorption liquid containing the absorption liquid main components are brought into contact, and the benzene contained in the natural gas is absorbed by the absorption liquid.

WO - 28.02.2019

Clasificación Internacional F25J 1/00 Nº de solicitud PCT/US2018/036895 Solicitante EXXONMOBIL UPSTREAM RESEARCH COMPANY Inventor/a VICTORY, Donald, J.

A drive system for liquefied natural gas (LNG) production. A standardized machinery string consisting of a multi-shaft gas turbine with no more than three compressor bodies, where the compressor bodies are applied to one or more refrigerant compressors employed in one or more refrigerant cycles (e.g., single mixed refrigerant, propane precooled mixed refrigerant, dual mixed refrigerant). The standardized machinery strings and associated standardized refrigerators are designed for a generic range of feed gas composition and ambient temperature conditions and are installed in opportunistic liquefaction plants without substantial reengineering and modifications. The approach captures DIBM ("Design 1 Build Many) cost and schedule efficiencies by allowing for broader variability in liquefaction efficiency with location and feed gas composition.
