An integral part of natural gas processing is the amine system which utilizes various types of amine solvents to selectively strip out CO2 (Carbon Dioxide) and H2S (Hydrogen Sulphide) as part of the sweetening process to make the gas fit for customer use.

Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkyl amines (commonly referred to simply as amines) to remove hydrogen sulphide (H2S) and carbon dioxide (CO2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing plants and other industries.

Amine Filtration

Operating an effectively designed amine filtration system will also reduce filter disposal costs and amine solvent losses and lead to a greener footprint from a reduced landfill perspective. It is important to reduce waste as much as possible. Optimizing a filter system that can effectively meet effluent specifications and provide the lowest cost per lb. of contaminant removal within the filter is key. PS Filter® has over 30 years’ experience working on amine applications to improve performance and reduce operating costs.


Effective Amine Filtration is a critical part of the gas processing system in many industries as it makes the gas fit for customer use. It is also important to ensure the process works as designed for maximum gas throughput and product sales.


Choosing the correct level and type of filtration  will provide an array of benefits such as reduced maintenance of downstream exchangers, pumps, and other equipment as well as a reduction in corrosion, and amine foaming and losses.


Utilizing effective filtration will also provide a greener footprint from a reduced landfill perspective as well as
environmental benefits by reducing the need to flare gas by keeping the amine system to a level of cleanliness so it can operate as designed.
