Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new applied sciences, particularly designed for use 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, including the risks related to the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on site and the wider surroundings ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a critical safety part that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ laws has elevated the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential dangers
The HF alkylation process poses a number of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. เกจวัดแรงดันสูง by its nature seeks out and attacks imperfections in cast metal parts that may ultimately scale back the life of pumps, valves and different equipment and worse still, end in product leakage. เกจวัดแรงดันลม -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the selection of material of cast elements, particularly by way of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use in hydrofluoric acid alkylation models and have been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next generation pumps are features which meet operator-specific needs for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply the necessary 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 chance of leakage into the surroundings, and decreasing operational dangers and the related costs to meet stringent environmental and health and security objectives. Finally, there is steady monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and safety in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to assist and keep and no supporting systems, the most recent magnetic drive sealless pump expertise provides important safety, value and operational advantages. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparability with standard mechanically sealed pumps.
