Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, specifically designed to be used in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, together with the risks associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on site and the broader setting ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a important safety element that offsets the excessive vapour pressure 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 also be liable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential risks
The HF alkylation process poses numerous critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in solid steel parts that may finally reduce the life of pumps, valves and different equipment and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice importance on the selection of fabric of solid components, particularly when it comes to the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use in hydrofluoric acid alkylation items and had been 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 technology and HMD Kontro, and using an innovative improvement course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new methods of Non-Destructive Examination (NDE).

Built into the design of those next generation pumps are options which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been proven to offer the mandatory resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential for leakage into the surroundings, and decreasing operational dangers and the related prices to meet stringent environmental and well being and safety goals. Finally, there may be continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection towards dry pump working (power control monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the latest magnetic drive sealless pump expertise offers significant security, price and operational benefits. Lower end-user installation costs and simplified maintenance necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
