Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new technologies, specifically designed for use in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, together with the dangers related to the dealing with of a deadly, extremely corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on site and the broader setting ought to leaks happen.
The course of
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 critical safety component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation process poses numerous severe environmental and well being 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 solid steel parts that will ultimately cut back the lifetime of pumps, valves and other equipment and worse still, result in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of fabric of cast components, significantly when it comes to the pump casing and impeller.
Designed for pressure gauge ออก หลัง against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed for use in hydrofluoric acid alkylation models and had been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an revolutionary development process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent generation pumps are options 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 necessary resistance to corrosion and likewise 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 surroundings, and lowering operational dangers and the associated costs to meet stringent environmental and well being and security goals. Finally, there is steady monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and safety against dry pump operating (power control monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the most recent magnetic drive sealless pump know-how presents significant safety, price and operational benefits. Lower end-user installation prices and simplified maintenance requirements, make it an effective whole-life proposition in comparability with typical mechanically sealed pumps.
