ASTM A179 Tubes Used for Amine Heat Exchangers & Coolers

Two lean amine coolers constructed by ASTM A179 tubes in tube pass.

Amine solutions are widely used in desulphurization and decarbonization process in fossil-fueled thermal plant, natural gas purification plant, coal chemical industry, and ammonia industry. The most common facilities are lean/rich amine heat exchangers and lean amine coolers, the tube pass of which is usually constructed by ASTM A179 seamless tubes. These tubes are made from ASTM A179 low carbon steel by a cold-drawn process mainly furnished in sizes (O.D) 1/8″ to 3″. The fluid flows through the tube pass is cooling water while amine solution is toward shell side.

A thermal power plant owned by South Luzon Thermal Energy Corporation (SLTEC). Nowadays environmental protection requirements have raised high standards for desulphurization.
