Performance Overview of STRATCO® Alkylation Technology
The STRATCO® Alkylation Technology is the predominant global sulfuric acid alkylation technology. The STRATCO® Alkylation Technology holds 75% of the global sulfuric acid alkylation market due to its numerous technological and operational advantages over competing technologies.
There are approximately seventy-five (75) STRATCO® Effluent Refrigerated Alkylation Units in commercial operation at refineries worldwide. Elessent Clean Technologies maintains an active relationship with these refineries. This broad experience has enabled Elessent to refine its process design, instrumentation, and operating procedures to provide market leading reliability and flexibility. Because of this, Elessent has been awarded over 100 Licenses for STRATCO® Effluent Refrigerated Alkylation Units, of which over 50 are repeat licensees for customers that have the STRATCO® Technology at more than one location.
Notable Licensing Achievements
Elessent Clean Technologies provides market leading reliability as STRATCO® alkylation units continue to operate worldwide more than sixty (60) years after initial startup. This reputation as a robust reliable technology has led to over fifty (50) repeat licenses as customers repeatedly choose the STRATCO® Alkylation Technology. Sinopec recently licensed its fifth STRATCO® Alkylation Unit in China, helping it to meet the country’s clean fuel demands as it moves to more stringent regulations.
Elessent has recently completed the successful start-up of the following STRATCO® alkylation units:
Elessent Clean Technologies has been awarded the two first ever licenses for the alkylation of a 100% isobutylene feedstock. Elessent completed a commercial test run at an existing alkylation unit where the existing unit feedstock was substituted with a 100% isobutylene feedstock. During the test run the predicted product quality of RON 95+ was achieved in a commercial setting. Read more about STRATCO® Alkylation Technology Butane-to-Alkylate applications.
100% Amylene Alkylation
Elessent Clean Technologies has been awarded the first ever license for the alkylation of a 100% amylene feedstock. Many operating STRATCO® alkylation units process some percentage of amylene olefins from the FCC, but this unit will be the first alkylation unit to process only amylenes. The design for this unit was optimized to utilize spent sulfuric acid from an adjacent alkylation unit that processes butylene olefins, helping to improve the overall economics of the project by maintaining current sulfuric acid infrastructure
