We provided front-end engineering design services to expand alkylation capacity at the Valero St. Charles Refinery. The primary business objective is to take advantage of untapped alkylation feedstocks and process incremental olefins.
The project consists of a new Lummus CDAlky unit with feed fractionation and selective hydrogenation technology to process olefins. Recent changes to the St. Charles refinery are expected to increase FCC olefin availability. The new alkylation unit consists of these process units:
A small revamp to the existing alkylation unit is part of the project scope. The revamp consists of:
The project also consists of an outside battery limits (OSBL) scope by the OSBL contractor and includes:
