Polyacetal (POM)

POM공장 전경.jpg
  • CAS No. 24969-26-4 (Copolymer)

  • Raw Material : Formaldehyde (45~55% concentration) , and 1,3-Dioxolane

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

  • Typical Grade G3, G9, G27, G52

  • 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

  • Product : Hydrogen peroxide (H2O2)

             Industrial grade and food grade of  27.5/35/50/60 wt%

  • P&ID Company’s Manufacturing Process

P&ID technology is one of the highly effective AO process in the world based on EAQ as the reaction carrier (working material). The major strengths and characteristics of main process step are fluidized hydrogenation, counter-current oxidation, effective extraction based on special internals, simple organic purification, safe concentration and easy regeneration without K2CO3 treatment Multiple consideration for safe operation and monitoring. No special option for procurement and raw material supply to be requested by licensor

Proposed Plant Capacity : 10,000 MTPA to 75,000 MTPA
