Advances in Sulfuric Acid Alkylation: McDermott’s Lummus CDAlky® Technology

Sponsor: McDermott Lummus Technology
With demand for alkylate rising, Lummus Technology’s CDAlky® gasoline alkylation process is a versatile solution for refiners utilizing readily available feedstocks to produce motor fuel alkylate. The low temperature sulfuric acid alkylation process reacts light olefin streams from a variety of sources such as fluid catalytic cracking units and steam cracking units together with isoparaffins to produce high performance motor fuel alkylate.
Central to the CDAlky process is an advanced reaction system design that significantly improves mass transfer relative to conventional contactors without using moving parts inside the reactor. The CDAlky reaction system operates at substantially lower temperatures than conventional alkylation processes, thus minimizing undesired side-reactions. CDAlky is therefore able to produce a higher quality alkylate product while consuming significantly less acid than conventional technologies. As CDAlky does not require rotating mixers or caustic/water post-treatment steps, the process is far less complex than conventional designs, thereby reducing initial capital cost, minimizing maintenance expense, and improving operational reliability.
Lummus Technology successfully commercialized the CDAlky process in 2013, and since then, interest in the technology has expanded dramatically. Lummus has established a strong position in the marketplace with 14 licensed units in place, and additional opportunities in the proposal and design pipeline. This webcast will introduce the key advantages of the CDAlky technology and will present options for improving refining operations by adopting this flexible, innovative technology.
