METHOD OF REMOVAL OF CARBONYL COMPOUNDS ALONG WITH ACID GASES FROM CRACKED GAS IN ETHYLENE PROCESS |
摘要 |
<p>A method for mitigating fouling in a wash unit used in a hydrocarbon cracking process wherein the fouling is due to the presence of polymers and deposits thereof formed by condensation of carbonyl compounds contained within a feed stream of the wash unit. In one embodiment, the invention provides a method of mitigating fouling in a wash unit by introducing into the feed stream an effective amount of an additive including: an inorganic salt of dithionite; and an epsilon caprolactam or a 6-amino caproic acid derivable therefrom. The additive scavenges the carbonyl compounds contained within the feed stream and dissolves deposits of the polymers to thereby mitigate fouling in the wash unit.</p> |
