DuPont™ has recently introduced its Kalrez® Spectrum™ 6380 perfluoroelastomer sealing parts, which have proven to offer outstanding resistance to amines and strong oxidisers at high temperatures in gas sweetening processes. 6380 parts exhibit 10 to 15 times lower swell than FKM, and four times lower swell than general purpose FFKM, in such environments.
The use of DuPont™ Kalrez® Spectrum™ 6380 parts in amine gas sweetening applications can extend the Meantime Between Repairs (MTBR) of valves and mechanical pump seals, reduce leakage and help contribute to reduced maintenance costs and lower emissions.
