Blending
Crude desalting
Gas crops
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be used for deadly, toxic and sub-zero fluid providers such as chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
