Publication number: 20140329983Abstract: Process for the manufacture of vinyl chloride monomer (VCM), comprising step 1): subjecting 1,2-dichloroethane (EDC) to pyrolysis in order to generate a gas mixture comprising VCM, hydrochloric acid (HCl), and EDC; step 2): quenching and/or cooling and/or condensing such gas mixture to a liquid+gas mixture; step 3): subjecting such liquid+gas mixture to a first separation step to remove substantially all the HCl from the liquid+gas mixture so as to leave a stream consisting substantially of VCM and EDC; and step 4): subjecting such VCM+EDC stream to a second separation step so as to get a stream of substantially pure VCM and a stream of unconverted EDC, wherein a heat exchanger is used to heat up the VCM+EDC stream prior to being fed to a distillation column in step 4), such heat exchanger being powered by a stream of hot fluid available in any one of steps 2) to 4) of the process.Type: ApplicationFiled: December 4, 2012Publication date: November 6, 2014Inventors: Andrea Salto, Maria Martin Carnicero, Paul Julius Degraeve, Michel Lempereur

Patent number: 8173855Abstract: Process for the production of ethylene for chemical use starting with a hydrocarbon source according to which: a) the hydrocarbon source is subjected to a first cracking step, namely a pyrolysis step carried out in a cracking oven, thus producing a mixture of cracking products; b) the mixture of cracking products is subjected to a succession of treatment steps, including a compression step, which makes it possible to obtain a purified crude gas stream; c) the purified crude gas stream is then cooled to a temperature where hydrocarbons with 6 and more carbon atoms condense so that they can be removed from the purified crude gas stream; d) the resulting purified gas stream is afterwards supplied to one separating column, where a fraction A containing hydrogen, methane and ethylene is separated at the head of the column and a heavy fraction C is separated at the bottom of the column; e) a part of the reflux of this column is supplied to a refrigeration cycle leading to a fraction B enriched with ethylene; and f)Type: GrantFiled: May 28, 2009Date of Patent: May 8, 2012Assignee: Solvay (Societe Anonyme)Inventors: Joachim Kotter, Hans-Dieter Winkler, Peter Mews, Michel Lempereur, Dominique Balthasart, Michel Strebelle

Patent number: 8049047Abstract: Process for the manufacture of 1,2-dichloroethane (DCE) starting with a hydrocarbon source which is subjected to a cracking thus producing a mixture of cracking products then subjected to treatment steps to obtain a mixture of products containing ethylene. The mixture is afterwards subjected to a first separation step into a fraction enriched with the compounds that are lighter than ethylene containing some of the ethylene conveyed to a chlorination reactor in which most of the ethylene is converted to DCE, and into a fraction F1 which is subjected to a second separation step into a fraction F2 and into a heavy fraction. Fraction F2 is afterwards subjected to a third separation step into a fraction enriched with ethylene conveyed to an oxychlorination reactor in which most of the ethylene is converted to DCE, and into a fraction F3 mainly composed of ethane.Type: GrantFiled: June 21, 2007Date of Patent: November 1, 2011Assignee: Solvay (Societé Anonyme)Inventors: Dominique Balthasart, Michel Lempereur, Michel Strebelle

Patent number: 7943099Abstract: A reactor for reacting at least two gases in the presence of a liquid phase, provided with an external liquid phase circulation device and including at least one injector for injecting the gases and the externally circulated liquid phase. In the injector the mixing of the gases together and with the externally circulated liquid phase only begins at the outlet of the injector.Type: GrantFiled: November 18, 2005Date of Patent: May 17, 2011Assignee: SOLVAY (Societe Anonyme)Inventors: Michel Strebelle, Michel Lempereur
