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

Butene-1 is produced at the MTBE plant and used as a copolymer for synthetic resin production.

  • Linear Low-Density Polyethylene(LLDPE)
