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 handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses explicit challenges to process operators, including the dangers associated with the dealing with of a lethal, highly corrosive fluid which poses a potential hazard to plant equipment, the people who work on web site and the wider environment ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a combination 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 safety part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ laws has elevated the demand for alkylate, which can also be liable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential risks
The HF alkylation course of poses a selection of serious environmental and health and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. เกจวัดแรงดันลมขนาดเล็ก by its nature seeks out and attacks imperfections in cast metallic components that will ultimately scale back the lifetime of pumps, valves and other gear 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 nice importance on the choice of material of solid parts, particularly in terms of the pump casing and impeller.
Designed for resistance towards 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 applied sciences have been particularly designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an innovative improvement process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined 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 needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the surroundings, and lowering operational dangers and the associated prices to fulfill stringent environmental and health and safety goals. Finally, there is steady monitoring to make sure a reliable sealless pump efficiency which includes leak detection instrumentation and safety in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer systems to support and keep and no supporting techniques, the latest magnetic drive sealless pump expertise offers important security, price and operational advantages. Lower end-user set up costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparison with standard mechanically sealed pumps.
