Kalrez® O-rings for Hydrogen Sulfide Removal
Amine units for hydrogen sulfide removal (H2S) at high temperatures use elastomers like Kalrez® Spectrum™ 6380 FFKM parts for resistance to amines. 6380 helps extend MTBR of valves and pumps in amine service.
O-rings in Pressurized Water Reactor
Due to the combination of extreme temperature, pressure and chemical environments, Kalrez® 0090 was used in a series of mechanical seals employed in the operation of boiler feed pumps for pressurized water reactors.
O-rings for Gas Sweetening Valves
Kalrez® 7090 perfluoroelastomer parts offer an excellent combination of chemical, Rapid Gas Decompression (RGD) resistance , and high temperature resistance for O-ring applications in gas sweetening valves that handle glycol-based solvents.
Parts for Amine Resistance
A major chemical company switched to Kalrez® Spectrum™ 6380 perfluoroelastomer parts to improve amine resistance & extend mean time between repairs. Improvement of up to 3x in MTBR achieved in a mechanical seal for hot, aggressive amines.
Kalrez® Spectrum™ 6380 parts for gas sweetening processes
Kalrez® Spectrum™ 6380 seals resist aggressive amines and oxidizers in gas sweetening treatments that damage most commonly used pump and valve seals.
