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