The Elessent™ ConvEx® HF alkylation conversion technology is the first cost-effective solution that enables refiners to convert volatile and toxic hydrofluoric acid (HF) alkylation units to safer sulfuric acid alkylation technology. While incorporating the highest safety standards, this new technology also offers refiners the opportunity for significant capacity increases at minimal additional cost.
By reusing much of the existing equipment, conversion with the Elessent™ ConvEx® technology can be achieved at approximately 40-60 % of the cost of a grassroots sulfuric acid alkylation unit. In situations where plot space is available near the existing facility, downtime can be reduced by installing new equipment during normal operations. With new equipment installation already complete, the remainder of the conversion work can be finalized within a typical 30-45 day turnaround window.
There are two reactor options when converting from an HF catalyzed unit to a sulfuric acid alkylation unit.
