Performance Overview of STRATCO® Alkylation Technology

Commercial Success

 

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.  DuPont Clean Technologies maintains an active relationship with these refineries. This broad experience has enabled DuPont to refine its process design, instrumentation, and operating procedures to provide market leading reliability and flexibility. Because of this, DuPont has been awarded over ninety (90) Licenses for STRATCO® Effluent Refrigerated Alkylation Units, of which over fifty (50) are repeat licensees for customers that have the STRATCO® Technology at more than one location.   

Notable Licensing Achievements

Repeat Licenses and start-up units

DuPont 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.  

DuPont has recently completed the successful start-up of the following STRATCO® alkylation units: 

Notable Licensing Achievements

Isobutylene Alkylation

DuPont Clean Technologies has been awarded the two first ever licenses for the alkylation of a 100% isobutylene feedstock. DuPont 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

Isobutylene Alkylation

100% Amylene Alkylation

DuPont 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
