- Treatment of sulphur-bearing gas to meet the requirements for use as fuel for GTPPs / GRPPs, oil heating furnaces, and boiler houses
- Gas with a hydrogen sulphide content of up to 0.1–0.2% mol can be treated to meet the requirements of STO Gazprom 089-2010
- Treatment of gas with a hydrogen sulphide content of up to 5% vol., at 100% humidity, and with a carbon dioxide content of up to 30–35% vol.
Carbon Dioxide and H2S removal from Gas Stream
Grasys membrane technology is the only technology that can simultaneously remove sulphur-bearing compounds (as well as CO2 and mercaptans) and dehydrate from hydrocarbons and/or water. It reduces not only hydrogen sulphide concentrations by a factor of 10–250, but also concentrations of water vapour, carbon dioxide and heavy hydrocarbons.
Membrane treatment of natural gas and associated petroleum gas is used both to separate the acid gases (CO2 and H2S) present in them to meet pipeline transport requirements and to remove methane during tertiary oil recovery for subsequent injection of carbon dioxide into the formation.
Natural gas and associated petroleum gas often contain chemically aggressive or easily condensable components that significantly affect the membrane performance and the degree of associated petroleum gas utilisation.
Grasys membrane technology is the only technology that can simultaneously remove sulphur-bearing compounds (as well as СО2 and mercaptans) and dehydrate from hydrocarbons and/or water.
With its extensive experience in membrane technology for various applications and a good understanding of the benefits of membrane technology, R&P Co. Grasys has carried out a series of scientific and applied research that has resulted in the development of a special membrane for the treatment of hydrocarbon gases with a high content of heavy hydrocarbons, water and sulphur-bearing impurities.
The principle of membrane separation of a gas mixture is based on the different penetration rates of its components through a polymeric membrane due to the differential partial pressures of the gas on either side of the membrane.
