Isobutane is a structural isomer of butane, which is used as an alternative to freon gas. It is a gas with a distinct odor at ambient temperature and atmospheric pressure.
CAS number : 75-28-5 / Molecular formula : C4 H10
The isobutane plant produce high-purity isobutane through distillation using the difference in boiling points of C4LPG and isobutane. After high-purity butane(C4LPG with Olefine less than 100 wt ppm) is produced through the second hydrogenation reaction with butane(C4LPG with Olefine less than 4 mol%) converted by the hydrogenation reaction of C4 Raffinate produced from each plant.
Isobutane is utilized as a polymer process dilution and charging gas.
