Polyacetal (POM)

  • CAS No. 24969-26-4 (Copolymer)

  • Raw Material : Formaldehyde (45~55% concentration) , and Ethylene oxide

  • Product : Copolymer of Polyacetal (Polyoxymethylene/POM, Acetal Resin)

  • Typical Grade G7, G27, G45

  • P&ID Company’s Manufacturing Process

Liquid reaction and production of co-polymers of Polyacetal through processing of Trioxane process (gas-liquid extraction) and polymerization process (continuous bulk polymerization) composing of the formalin concentration unit, monomer(Trioxane/TOX) unit, co-monomer unit, polymerization unit (continuous bulk polymerization), stabilization unit, formalin recovery process, and packing and storing unit.

Methyl Isobutyl Ketone (MIBK)

  • CAS No. 108-10-1

  • Raw Material : Hydrogen (98 vol%), Acetone (99.5%)

  • Product : MIBK ((CH₃)₂CHCH₂COCH₃, Min. 99.1%) and DiBK (2,6-Dimehyl-4-heptanone : By-Product)

  • P&ID Company’s Manufacturing Process

MIBK is produced from liquid acetone (Dimethyl Ketone) and gaseous hydrogen by contacting with a catalyst, strong acid cation exchange resin loaded with 0.7wt% palladium, through main system of Reaction, C6 Removal, Acetone Recovery, MIBK Separation, MIBK Concentration, DiBK Concentration.

Proposed Plant Capacity : 15,000 MTPA

Hydrogen Peroxide (H2O2)

  • CAS No. 7722-84-1

  • Raw Material : Hydrogen(99.9%), Air, Anthraquinone, Solvents, Pd catalyst
