Two-Phase Scrubber Design as Test Separator for Gas Wells

Abstract. 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.
