Put ethylene at gas phase in the Compressor.
mechanical device used for compressing gas to increase pressure
Put compressed ethylene in the Reactor with Initiator.
a device used for chemical reaction.
a substance that initiates a chemical reaction or polymerization.
In this process, the LDPE product is converted into uniform sized pellets.
Unreacted ethylene is recovered through a separator and reused.
Products are stored and inspected before they are shipped.
VCM, water and raw supplements are put in a reactor and heated.
Slurry (a mixture of solids and liquids) that comes out of the reactor is put into the stripping column through the top. Steam is blown into the bottom of the stripping column to remove unused VCM in the slurry. The left-over VCM is reused.
The slurry becomes dehydrated by being passed through a decanter (centrifuge). It is then passed through a dryer with coils immersed in hot water. Hot air in the dryer and the coil in hot water maintain the temperature necessary to turn the slurry into a PVC resin of powdery state.
PVC resin is stored in a silo then packed and shipped.
Salt is dissolved in water through a purification process to remove impurities.
After removing impurities, the salt water is put in an electrolyzer to break down into Chlorine, Caustic Soda and Hydrogen.
TDA and COCl2 produce TDI(main product)
and HCl(by-product) through TDA Phosgenation.
substance produced by reacting Hydrogen with DNT
substance produced by reacting Chlorine with CO
TDI, HCl and other byproducts are separated after being produced in the reaction process.
TAR and other light products are removed from TDI.
Final TDI product in liquid form is stored and shipped in tanks or drums.
