Description:
As a worldwide licenser and operator of HF alkylation units, Phillips has continually researched ways to improve both the operability and safety of Phillips HF alkylation technology over the past 50 years. In the past, physical risk reduction features have been incorporated into Phillips HF alkylation units. ’ Some of these have included 1) A Self Circulating Reactor 2) Remote Operating Isolation Valves, 3) Reactor Acid Compartmentalization, 4) Rapid Gravity Acid Transfer and 5) Reduced Acid Inventory Requirements. Today, a Reduced Volatility Alkylation Process has been developed that utilizes an additive to reduce airborne HF migration downwind in the event of an accidental acid catalyst release. The additive is a nun-volatile, non-odorous, low toxicity material that is both stable and compatible with HF and existing HF alkylation metallurgy. Coupled with the mechanical features previously mentioned, Quantitative Risk Analysis results are expected to be decreased by several orders of magnitude when compared to older designs. The risk associated with HF transport, although low, may also be mitigated by transporting the additive with HF acid shipments. Since the additive does not undergo a chemical reaction with the HF, the additive can be separated from HF and recycled, if necessary, without chemical consumption loss.
