PROCESS FOR THE MANUFACTURE OF AT LEAST ONE ETHYLENE DERIVATIVE COMPOUND

摘要

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 undesirable components present therein and to obtain a mixture of products containing ethylene and other constituents ;
b) the said mixture of products is separated in one separation step into a fraction containing almost all the ethylene (fraction A) and into a heavy fraction (fraction C) ; and
c) fraction A is conveyed to the manufacture of at least one ethylene derivative compound.
