Intro to Products
MTBE
MTBE is produced by the reaction of ISOBUTENE in C4 Raffinate-1 with methanol (esterification) to produce high-purity ISOBUTENE.
CAS number : 1634-04-4 / Molecular formula : C5H12O
Plant processes
This unit consists of the reaction unit that selectively lets the Isobutene, contained in C4 Raffinate-1, react with methanol using a catalyst (etherification) to produce MTBE, and the refining unit that fractionates unresponsive C4 Raffinate-1 and high-purity MTBE.

- MTBE Synthesis Unit
- This unit consists of the reaction process that selectively lets the isobutene, contained in C4 Raffinate-1, react with methanol using a catalyst (etherification) to produce MTBE, and the refining unit that fractionates unresponsive C4 Raffinate-1 and high-purity MTBE.
-
- Isobutene Manufacturing Unit
- This unit fractionates methanol by cracking the MTBE, produced by catalyst process of the MTBE synthesis unit, and recovers high-purity isobutene.
-
- Butene-1 Recovery Unit
- Among the residual C4 Raffinate-2, produced by the MTBE synthesis unit, this unit selectively hydrogenates BD, VA, PD and EA, fractionating high-purity butene-1 in the refining system.
Product uses
MTBE is produced at the MTBE plant with C4 Raffinate-1 as feedstock, and used for gasoline additive or high-purity Isobutene production.
