Vinyl chloride monomer VCM

A VCM (vinyl chloride monomer) production unit uses three vertically mounted agitated reactors for the polymerization of vinyl chloride. Crude material balances infer about 8 to 10% monomer losses. Describe how you would go about assessing whether these losses are due to leaks such as fugitive air emissions. Be specific in recommending procedures and instruments. [Pg.147]

World-wide consumption of PVC [poly(vinyl chloride)] has increased dramatically in the past few years. It has now exceeded 8 billion lbs annually. The production of VCM (vinyl chloride monomer) has also been expanded to meet the PVC demand. Future trends for VCM and PVC pro-ductions for the next five years can be forecast on the basis of the raw materials sources, the different process techniques in manufacturing VCM and PVC, and their relative economics, technical merits, and limitations. VCM will be produced principally through the ethylene route by fluid-bed oxyhydrochlorination of ethylene and thermal cracking of ethylene dichloride. PVC will be produced by various processes resulting in more specialized PVC varieties tailored for specific end markets and new processing technologies. [Pg.193]

Vinyl Chloride Monomer (VCM). Vinyl chloride monomer (VCM), bp -13.4°C, is a gas at room temperature and pressure. Therefore, it is handled as a compressed volatile liquid in all polymerization operations. Its vapor pressure over the typical polymerization temperature range of 50-70°C is 800-1250 kPa. As a result, PVC polymerization reactors are thick-walled jacketed steel vessels with a pressure rating of 1725 kPa. VCM is slightly soluble in water (0.11 wt% at 20°C). This has some influence on the suspension polymerization process and is critically important to the success of the emulsion polymerization process. The... [Pg.8928]

Butanediol. In 1988, 400 million lb of 1,4-butanediol were made, of which 120 million lb were sold. This is up from 300 million lb reported in 1978. Of the chemical uses of acetylene, 1,4-butanediol is the largest consumer other than VCM (Vinyl Chloride Monomer). The use of acetylene to make VCM is now considered outdated, and it is a minor process compared to the production of VCM from ethylene. [Pg.808]
