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 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, highly corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on website and the wider environment ought to leaks happen.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a critical security component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ legislation has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential dangers
The HF alkylation course of poses a selection of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in cast metallic parts that may ultimately 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 great significance on the choice of material of forged parts, particularly in phrases of the pump casing and impeller.
Designed for เกจวัดแรงดันออกซิเจนราคา in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps provide whole 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 items and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and utilizing an progressive development 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 strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next era pumps are options which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been proven to offer the mandatory 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 possibility of leakage into the surroundings, and decreasing operational risks and the related costs to fulfill stringent environmental and health and security objectives. Finally, there is steady monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and safety in opposition to dry pump working (power control monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the newest magnetic drive sealless pump expertise provides significant safety, value and operational benefits. Lower end-user installation prices and simplified maintenance requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
