CO2 Removal

CO2 is commonly found compound in natural gas. Carbon dioxide (CO2) is found in oil and gas fields in varying concentrations. Dry CO2, be it in gas phase or a supercritical fluid is not corrosive to metals and alloys. However, in presence of water-containing produced fluids, severe corrosion of the infrastructure may result due to the formation of carbonic acid. In order to meet pipeline specifications or other application specific requirements,  CO2 separation is necessary.

HAWK ENERGY offers integrated membrane-based systems for low cost & compact solution in order to reduce the CO2 content in the natural gas. The membrane systems provide a safe and efficient option for water vapor and carbon dioxide removal from natural gas, especially in remote locations. These membranes have very high separation efficiency and requires minimal pre-treatment. The membrane system is tailored to fit your application with a hydrocarbon recovery of >95%. The membranes are used for achieving pipeline CO2 specifications of 4 mol% or less or for bulk CO2 removal.


  • Advance permeate technology
  • Robust, proven membrane performance at high CO2 contents
  • CO2 content reduced to required specifications (<4 mol% or optimal levels)
  • Robust membrane technology requiring minimal pretreatment leading to reduced CAPEX and OPEX
