Elessent has dozens of operating units worldwide processing an olefin feedstock from an FCC unit. A FCC mixed butylene feedstock is the most common feedstock to an alkylation unit. These feeds produce an alkylate product with a 96-97 RON depending on the amount of isobutylene present.
The STRATCO® alkylation technology is flexible and able to handle changes in feedstock composition or rate resulting from a change in operation of the upstream FCC unit. The STRATCO® alkylation technology is still able to produce the highest quality alkylate in the event of a new catalyst or increased throughput in the FCC unit. Refiners in the U.S. and throughout the world operate Elessent Clean Technologies’ STRATCO® alkylation units processing FCC types feeds with varying levels of C3 and C5 olefins. This flexibility allows Elessent customers the ability to adapt with the marketplace efficiently and cost effectively.
The Elessent STRATCO® alkylation technology has successfully started up 11 grassroots alkylation units processing FCC olefin feeds since 2009. Details of these units can be seen below. An additional eight licenses for future alkylation units processing FCC olefins have been awarded during the same time frame.
