Title
(EN) PRODUCTION OF ETHYLENE DICHLORIDE BY DIRECT CHLORINATION AND PRODUCTION OF VINYL CHLORIDE MONOMER USING CHLORINE RECYCLE
(FR) PRODUCTION DE DICHLORURE D'ETHYLENE PAR CHLORATION DIRECTE ET PRODUCTION D'UN MONOMERE DE CHLORURE DE VINYLE A L'AIDE DE CHLORE RECYCLE
Abstract
(EN)
A process and a system uses a direct chlorination reactor for producing ethylene dichloride by direct chlorination, without the need for an oxychlorination unit. This ethylene dichloride may be used to make vinyl chloride monomer. In the process for making ethylene dichloride, ethylene and chlorine are both supplied to a direct chlorination reactor. The ethylene reacts with the chlorine to form ethylene dichloride. Chlorine is supplied to the direct chlorination reactor from an electrochemical cell which converts anhydrous hydrogen chloride to dry chlorine gas. This chlorine gas is purified and liquefied to form liquid dry chlorine, and the liquid dry chlorine is recycled to the direct chlorination reactor. The ethylene dichloride may be pyrolyzed to produce vinyl chloride monomer and anhydrous hydrogen chloride.
(FR)
L'invention concerne un procédé et un système mettant en oeuvre un réacteur de chloration directe ou produire du dichlorure d'éthylène par chloration directe sans recourir à une unité d'oxychloration. Ce dichlorure d'éthylène peut s'utiliser pour fabriquer un monomère de chlorure de vinyle. Dans le procédé pour fabriquer du dichlorure d'éthylène, l'éthylène et le chlore sont tous deux fournis par un réacteur de chloration directe. L'éthylène réagit avec le chlore pour former du dichlorure d'éthylène. Du chlore est acheminé audit réacteur depuis une cellule électrochimique convertissant du chlorure d'hydrogène anhydre en chlore gazeux sec. Ce dernier est purifié et liquéfié pour former du chlore sec liquide, lequel est recyclé vers le réacteur de chloration directe. Le dichlorure d'éthylène peut être pyrolysé pour produire un monomère de chlorure de vinyle et du chlorure d'hydrogène anhydre.
