How Guichon performs on steam crackers

Steam cracking is the first step to produce the simplest olefin: Ethylene. It is one of the simplest of all the olefins and present everywhere around us. It is used as base product for several applications: Plastics, paints, solvents, packaging, cosmetics… The worldwide ethylene demand is now over 140 million tons per year and is still growing by 4-5% every year!

Guichon Valves has been installing several tailored valve solutions on steam crackers for more than 40 years. All of them are still working at a good performance and reasonable operating/maintenance prices.

Our technical team is going worldwide and helping our customers to maintain their cracking gas isolation valves. This is happening basically every 6 years, for the periodical turnaround.

More information

Focus application : vinyl chloride and polyvinyl chloride

Vinyl chloride (VCM), is an industrial chemical compound, mainly used to produce its polymer: polyvinyl chloride (PVC).

PVC is the third high consumption thermoplastic polymer (after polyethylene and polypropylene).

It is produced through vinyl chloride monomer (VCM) polymerization. The main polymerization processes include suspension, emulsion and mass polymerization.

Guichon Valves offers valves specially adapted to viscous liquids and designed to minimize pressure losses and dead spots. Sealing materials (packing, gaskets, etc.…) are selected not to pollute the circulating fluid.
