Natural gas production from the wellhead is a complex mixture of gas and liquids contained in the gas. The liquid that is also produced from natural gas production will be in the form of liquid droplets and needs to be separated from the gas. A two-phase scrubber is a two-phase separator used to recover liquids carried away from natural gas production. Gas from the wellhead will enter the scrubber with a certain pressure and temperature according to the operating pressure and operating temperature and is held in the scrubber for some time (retention time). Due to the high working pressure, the scrubber tank is included in the pressure vessel category, and therefore the design process must be carried out correctly and follow the latest ASME BPVC standard (American Society of Mechanical Engineers standard of Boiler and Pressure Vessel Code) documentation. The design carried out is to determine the design, material, and dimensions of the main components of the two-phase scrubber tank. The results of the design are technical drawings and welding recommendations, as well as the finishing process of the two-phase scrubber.
