Boiling reactor
16 Sep 2004
The German firm Uhde has been awarded a contract by the Belgian chemical company Limburgse Vinyl Maatschappij (LVM), a member of the Tessenderlo group, for a new ethylene dichloride (EDC) plant that will use the company's new Vinnolit-Uhde boiling reactor technology.
The plant will be built at LVM's site in Tessenderlo, Belgium, and will have an annual capacity of 250,000 tonnes of EDC. It is scheduled to come onstream in 2006.
This will be the first industrial-scale application of the new Vinnolit-Uhde technology for the production of EDC through the direct chlorination of ethylene using the new boiling reactor.
In this reactor, which has been developed jointly by Uhde and Vinnolit, liquid-phase ethylene reacts catalytically with chlorine to form EDC. The chlorine for the new plant will be produced at a membrane electrolysis plant currently being built by Uhde at the same location for Tessenderlo Chemie.
The company claims that EDC produced using the technique is of such a high quality that distillative purification is no longer necessary and it can be used immediately as feedstock for the production of vinyl chloride monomer (VCM) or offered for sale.
VCM will be manufactured as an intermediate from the EDC produced at the plant and this in turn will be used to manufacture PVC.
