Definitions
- the present invention relates to a simplified cracking process for petroleum products, in particular hydrocarbons, which is coupled to chlorination of ethylene.
- cracking of various heavy petroleum products is still carried out to form ethylene.
- This is separated from light by-products such as hydrogen, methane and ethane by costly and complex processes.
- light by-products such as hydrogen, methane and ethane by costly and complex processes.
- several ways of direct recovery of ethane to vinyl chloride are known in the literature: - oxychlorination of ethane in a fluid bed and recovery of by-products
- the process of the invention has the advantages that it does not require: no recovery of heavy products, no separation of ethylene from the ethylene-ethane-methane and hydrogen mixture. Another advantage is that the ethane can be recovered and recycled in the cracking furnace. To do this, a absorption desorption process in a chlorinated organic solvent is preferably used. Examples of such chlorinated organic solvents are 1,2-dichloroethane, tetrachloride carbon or chlorobenzene. 1,2-Dichloroethane is particularly suitable in the process of the invention.
- the invention relates to a process in which ethylene is chlorinated in the presence of the impurities obtained during the cracking of petroleum products, in particular of hydrocarbons.
- the invention relates to a hydrocarbon cracking process coupled with the production of 1,2-dichloroethane in which the ethylene obtained during this process is separated from the other products by a chlorination step.
- the hydrocarbons considered are mixtures of hydrocarbons mainly consisting of ethane.
- the hydrocarbon considered is ethane and the invention relates to an ethane cracking process coupled with a production of 1,2-dichloroethane according to which the ethylene obtained during this process is separated from the other products by a chlorination stage.
- the chlorination reaction is carried out remarkably selectively in a liquid phase (preferably 1,2-dichloroethane essentially) containing a dissolved catalyst such as FeCl3 or another Lewis acid.
- a dissolved catalyst such as FeCl3 or another Lewis acid.
- This catalyst can advantageously be combined with co-catalysts such as alkali chlorides.
- a couple which has given good results is the FeCl3 couple with LiCl as catalytic system.
- the chlorination process according to the invention is preferably carried out at temperatures between 30 and 150 ° C. Good results have been obtained whatever the pressure both at a temperature below the boiling temperature and at the boiling temperature itself. Particularly preferred is a process of chlorination at boiling which allows, if necessary, to usefully recover the heat of reaction.
- the process of the invention is generally carried out in a chlorinated organic liquid medium.
- this chlorinated organic liquid medium also called liquid base, is 1,2-dichloroethane.
- the amounts of FeCl 3 usually used are of the order of 1 to 10 g of FeCl 3 per kg of liquid base.
- the molar ratio of FeCl 3 to LiCl is generally of the order of 0.5 to 2.
- the mixture containing ethylene as well as chlorine can be introduced by any known device into the reaction medium. It is for example known (Patent DE 4026882) that these reagents can be introduced separately.
- Patent DE 4026882 Patent DE 4026882
- Chlorine is added in sufficient quantity to convert most of the ethylene without requiring the addition of excess unconverted chlorine.
- the C12 / C2H4 ratio used is preferably between 1.2 and 0.8 and preferably between 1.05 and 0.95 mol / mol.
- the chlorine products obtained essentially contain 1,2-dichloroethane as well as small quantities of by-products such as 1,1,2-trichloroethane or small quantities of chlorination products of ethane or methane.
- the purification of 1,2-dichorethane takes place according to known modes and generally makes it possible to exploit the heat of the chlorination reaction.
- the unconverted products (C2Hg, CH4, CO and H2) are then subjected to an easier separation than that which would have been necessary to separate pure ethylene from the initial mixture.
- the ethane is preferably separated from the gases not converted to chlorination by means of an absorption-desorption cycle in a suitable solvent.
- suitable solvents are usually chosen from 1,2-dichloroethane, carbon tetrachloride or even chlorobenzene.
- the ethane thus separated is preferably recycled to cracking.
- the method can also comprise steps known from cracking methods such as:
- recycling methane can prove to be advantageous in order to benefit, by oxidative coupling thereof, from an additional ethylene.
- This is particularly the case for cracking processes using catalysts in an oxidizing medium thanks to the presence of oxygen (catalytic cracking).
