Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes 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 application which poses specific challenges to process operators, together with the dangers related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on website and the broader setting ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important security component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential dangers
The HF alkylation course of poses a variety of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in forged metal elements that can ultimately scale back the life of pumps, valves and different gear 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 places great significance on the choice of fabric of solid parts, notably by way of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation models and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and utilizing an innovative development course of, the HMD Kontro HF pump includes a high 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 those next technology pumps are options which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been proven to offer the required resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the setting, and decreasing operational risks and the associated prices to satisfy stringent environmental and health and safety objectives. Finally, there is continuous monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection towards dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to support and maintain and no supporting techniques, the latest magnetic drive sealless pump know-how presents significant security, cost and operational benefits. Lower end-user set up costs and simplified maintenance requirements, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
