Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, specifically designed to be used 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 application which poses particular challenges to course of operators, including the dangers associated with the handling of a deadly, extremely corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on site and the broader 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 provide alkylate. A high-octane additive, alkylate is a critical security component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of clean 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 risks

The HF alkylation course of poses a variety of serious environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in solid metallic elements that can finally scale back the lifetime of pumps, valves and different equipment 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 significance on the choice of fabric of solid parts, significantly in terms of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed to be used in hydrofluoric acid alkylation units 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 expertise and HMD Kontro, and using an progressive development course of, the HMD Kontro HF pump features 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).
Specialist design options

Built into the design of those subsequent generation pumps are features which meet operator-specific wants for the HF alkylation course of. ร้านซ่อมเครื่องวัดความดันโลหิต embrace a pump casing in Alloy C22 materials, which has been confirmed to offer the necessary resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the possibility of leakage into the environment, and lowering operational risks and the related prices to meet stringent environmental and well being and safety objectives. Finally, there is steady monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and safety against dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting methods, the newest magnetic drive sealless pump expertise offers significant safety, price and operational advantages. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
