Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring 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 explicit challenges to course of operators, together with 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 site and the broader setting ought to leaks happen.
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 provide alkylate. A high-octane additive, alkylate is a critical security part that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential dangers
The HF alkylation course of poses numerous serious environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in forged metal elements that can ultimately scale back the life of pumps, valves and other equipment and worse still, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. compound gauge ราคา and damaging nature of HF acid places nice importance on the choice of fabric of forged elements, 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 offer total 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 had been developed in response to the challenges of dealing with 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 utilizing an innovative improvement process, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next era 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 proven to supply the required resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential of leakage into the surroundings, and reducing operational risks and the related prices to satisfy stringent environmental and health and safety targets. Finally, there may be continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety against dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to assist and maintain and no supporting methods, the latest magnetic drive sealless pump expertise presents significant security, value and operational benefits. Lower end-user set up costs and simplified maintenance necessities, make it an efficient whole-life proposition compared to conventional mechanically sealed pumps.
