[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.

8.WO/2017/112005COMPOSITION AND METHOD OF MAKING AQUEOUS PENETRATING INKJET INK

WO - 29.06.2017

국제특허분류 C09D 11/00 출원번호 PCT/US2016/048025 출원인 TROY GROUP, INC. 발명자 CAI, Xiaorong

An aqueous penetrating ink includes a pigment and a water-soluble dye. The ink also includes a humectant in which the water-soluble dye is to be at least partially dissolved. The humectant is present in the ink between 20 percent by weight and 70 percent by weight. This amount of humectant results in a slow evaporation rate. The ink also includes water, making it suitable for use with some inkjet printers. Because the pigment is not dissolved in the humectant or the water, it forms an image on the surface of a printed side of a substrate. The slow evaporation rate of the humectant allows it to carry the ink through a thickness of a substrate so that it is visible on a non-printed side of the substrate.

9.WO/2020/225542APPARATUS AND METHOD RELATING TO MANAGED PRESSURE DRILLING

WO - 12.11.2020

국제특허분류 E21B 17/01 출원번호 PCT/GB2020/051084 출원인 OIL STATES INDUSTRIES (UK) LIMITED 발명자 MARTINS, Miguel Fernandes

An actuatable sealing mechanism ( 1030, 1034, 1038; 2030, 2034, 2038; 3007 ) for sealing a fluid channel ( 1024; 2024; 3013 ) provided between two co-axially arranged tubular members ( 1010 & 1100, 1200, 1300; 2010 & 2100, 2200, 2300; 3010, 3012 ) having a central longitudinal axis. The actuable sealing mechanism comprises an elastomeric seal ( 1209; 2209; 3015 ), an axially moveable actuating sleeve member ( 1400; 2400; 3020 ) and a radially moveable activating member ( 1060, 1064, 1068; 2060, 2064, 2068; 3025 ). The activating member is configured to be moveable in a radial direction in use to translate the actuatable sealing mechanism between an unsealed state and a sealed state. When it is in the unsealed state, the activating member does not move the actuating sleeve member sufficiently in a first axial direction to axially compress the elastomeric seal sufficiently to expand the elastomeric seal in a radial direction to seal the fluid channel.

10.WO/2019/040154METHOD AND SYSTEM FOR LNG PRODUCTION USING STANDARDIZED MULTI-SHAFT GAS TURBINES, COMPRESSORS AND REFRIGERANT SYSTEMS

WO - 28.02.2019

국제특허분류 F25J 1/00 출원번호 PCT/US2018/036895 출원인 EXXONMOBIL UPSTREAM RESEARCH COMPANY 발명자 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.
