Chemical manufacturing (derivatives)

chemical general process

  • VCM manufacturing process
  • Butadiene rubber manufacturing process
  • Ammonia manufacturing process

 

VCM manufacturing process

Vinyl Chloride Monomer (VCM) is used to produce polymer polyvinyl chloride (PVC). It is a toxic and flammable gas under ambient temperature and pressure.

VCM manufacturing processThere are two methods to produce VCM:

  • the direct chlorination
  • and the oxychlorin

This two methods are combined in major VCM plants. Both processes use ethylene dichloride (EDC) to produce VCM.
In the direct chlorination, EDC is generated through the reaction of chlorine with catalyst, while in oxychlorination method, it is generated through the reaction of hydrogen chloride and ethylene under the presence of catalyst and air (O2).

Instrumentation used:

  • Pressure monitoring (FCX AII series Pressure Transmitters)
  • Flow measurement for fuel, gas, liquids (FKC differential pressure transmitter, FKD remote seals differential pressure transmitter, FST ultrasonic flowmeter)
  • Flow measurement for cooling water (Ultrasonic flowmeter  FSC FSS, Time Delta-C)
  • Temperature measurement control (PXF, PXR, PXG, PXE, PXH, PUM)

Butadiene rubber manufacturing processbutadiene rubber manufacturing process

Butadiene rubber is a synthetic rubber widely produced and used due to its high resistance to abrasion.
It is blended with other feedstock rubbers, processed with roll mixing mills or extruders, and vulcanized, to elastic rubber.
In North America, Europe and Japan, butadiene is obtained as by-products through catalytic cracking of ethylene or other olefins.

Applications: Production of car tyres, footwear, conveyor belts, hoses, toys, molded rubber goods, sponge and foamed products, waterproof materials, belting, adhesives

Instrumentation used:

  • Pressure monitoring (FCX AII series Pressure Transmitters)
  • Flow measurement for fuel, gas, liquids (FKC differential pressure transmitter, FKD remote seals differential pressure transmitter, FST ultrasonic flowmeter)
  • Flow measurement for cooling water (Ultrasonic flowmeter  FSC FSS, Time Delta-C)
  • Temperature measurement control (PXF, PXR, PXG, PXE, PXH, PUM)
  • Combustion control of air-heating furnace (Ex-proof in situ zirconia oxygen analyzer, Cross stack laser gas analyzer)

Ammonia manufacturing process

Ammonia is a chemical compound which is the most produced in the world. About 80% of ammonia is used in the production of agricultural fertilizer. The remaining 20% is used for the production of synthetic fibers(nylon, rayon). Ammonia is produced in the Habber-Bosch process: Atmospheric nitrogen reacts with hydrogen to form ammonia. Hydrogen can be produced in many ways but usually it is obtained by cracking natural gas (methane) or petroleum feedstock (naptha). Hydrogen is also recovered from recycled plastic (chemical recycling).
