<p>Process for the manufacture of at least one ethylene derivative compound starting from a low value residual gas, preferably a ROG, according to which :
a) the low value residual gas is subjected to a series of treatment steps in a low value residual gas recovery unit in order to remove the contaminants present therein and to obtain a mixture of products containing ethylene and other constituents;
b) the said mixture of products is separated into a fraction enriched with compounds which are lighter than ethylene, containing part of the ethylene (fraction A), into a fraction enriched with ethylene (fraction B) and into a heavy fraction (fraction C);
c) fraction A and fraction B are conveyed to the manufacture of at least one ethylene derivative compound.</p> |
