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 dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to process operators, including the risks associated with the handling of a deadly, extremely corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on website and the wider surroundings ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. weksler ea14 -octane additive, alkylate is a crucial security element that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation course of poses numerous critical environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in cast steel parts that will finally reduce the life of pumps, valves and different gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places great importance on the choice of material of solid components, notably when it comes to the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies 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 results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation technology and HMD Kontro, and utilizing an progressive growth course of, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent era pumps are features which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 materials, which has been proven to offer 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 risk of leakage into the environment, and reducing operational dangers and the associated costs to satisfy stringent environmental and well being and security objectives. Finally, there is continuous monitoring to ensure a dependable sealless pump performance which includes leak detection instrumentation and protection towards dry pump operating (power management monitor).
With no seals to leak, no seal buffer systems to help and preserve and no supporting systems, the most recent magnetic drive sealless pump know-how provides vital safety, price and operational benefits. Lower end-user installation costs and simplified maintenance necessities, make it an effective whole-life proposition in comparability with typical mechanically sealed pumps.
