Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new technologies, specifically designed to be used 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 specific challenges to course of operators, including the risks associated with the handling of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on website and the broader environment ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important security component that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential risks
The HF alkylation process poses a selection of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in cast metallic elements that will in the end cut back the lifetime of pumps, valves and different tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places great significance on the choice of material of forged elements, notably when it comes to the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as 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 were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and using an progressive growth course of, the HMD Kontro HF pump features 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 features
Built into the design of these subsequent era pumps are options which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been confirmed to supply the necessary resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the setting, and reducing operational risks and the related costs to fulfill stringent environmental and health and safety goals. Finally, there is continuous monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump working (power management 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 expertise offers significant safety, price and operational benefits. เครื่องมือที่ใช้วัดความดันเลือด -user set up prices and simplified upkeep necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
