Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, 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 risks related to the handling of a lethal, highly corrosive fluid which poses a possible hazard to plant gear, the people who work on site and the wider setting should leaks happen.
The course of

HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a crucial safety element that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ laws has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential dangers

The HF alkylation process poses a quantity of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in cast metallic elements that may ultimately scale back the lifetime of pumps, valves and different tools and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. pressure gauge octa and damaging nature of HF acid locations great significance on the selection of material of cast parts, particularly in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump

The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive improvement 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 utilizing new methods of Non-Destructive Examination (NDE).

Built into the design of those next technology pumps are features which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to supply the required resistance to corrosion and likewise meets NDE necessities 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 lowering operational risks and the associated prices to satisfy stringent environmental and health and safety objectives. Finally, there’s continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting techniques, the most recent magnetic drive sealless pump know-how offers vital safety, value and operational advantages. Lower end-user set up prices and simplified upkeep requirements, make it an efficient whole-life proposition in comparison with conventional mechanically sealed pumps.
