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 handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to course of operators, including the dangers related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant equipment, the people who work on website and the broader surroundings should 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. เพรสเชอร์เกจคือ -octane additive, alkylate is a important safety component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ laws has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential risks
The HF alkylation course of poses numerous critical environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in solid steel elements that may finally scale back the life of pumps, valves and other tools and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of fabric of cast components, notably in terms of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids such as HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly 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 main licensor of HF alkylation technology and HMD Kontro, and using an progressive development course of, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next era pumps are options which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to supply 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 potential of leakage into the setting, and lowering operational dangers and the related prices to meet stringent environmental and well being and safety goals. Finally, there’s steady monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection against dry pump operating (power management monitor).
With no seals to leak, no seal buffer systems to assist and maintain and no supporting methods, the most recent magnetic drive sealless pump know-how offers significant safety, cost and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
