Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, together with the dangers related to the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the people who work on site and the wider surroundings ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important security element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of clean fuels’ laws has elevated the demand for alkylate, which can be answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential dangers
The HF alkylation process poses a number of critical environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in solid metal elements that will in the end scale back the life of pumps, valves and other equipment and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of material of solid elements, notably by method of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation models and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent technology pumps are features which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been proven to offer the necessary resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the setting, and lowering operational dangers and the associated prices to fulfill stringent environmental and well being and security objectives. Finally, there is steady monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and protection towards dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting methods, the newest magnetic drive sealless pump expertise presents vital safety, price and operational advantages. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
