Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring 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 software which poses particular challenges to process operators, including the dangers related to the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on website 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 produce alkylate. เกจวัดแรงดัน250bar -octane additive, alkylate is a important security part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which can additionally be answerable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential dangers
The HF alkylation process poses a selection of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in forged steel elements that will ultimately scale back the life of pumps, valves and different gear and worse nonetheless, end in 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 cast elements, particularly in terms of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation items and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump includes a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next era pumps are features which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to supply the mandatory resistance to corrosion and also meets NDE requirements 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 associated costs to satisfy stringent environmental and well being and safety targets. Finally, there’s steady monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and protection in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to assist and keep and no supporting methods, the newest magnetic drive sealless pump know-how presents important safety, value and operational advantages. Lower end-user set up costs and simplified upkeep necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
