Sealless pump design tackles HF alkylation

เกจวัดแรงดันน้ำ4หุน that includes new applied sciences, 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 specific challenges to course of operators, together with 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 site and the wider setting 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 supply alkylate. A high-octane additive, alkylate is a critical safety element that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous 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 well being 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 solid metal components that can ultimately reduce the life of pumps, valves and different tools and worse still, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of material of forged elements, notably when it comes to the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed to be used in hydrofluoric acid alkylation items and had been 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 know-how and HMD Kontro, and using an progressive development process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested 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 needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been proven to offer the required resistance to corrosion and likewise meets NDE requirements 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 environment, and reducing operational dangers and the related costs to fulfill stringent environmental and well being and security goals. Finally, there could be continuous monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the newest magnetic drive sealless pump technology presents significant safety, cost and operational benefits. Lower end-user set up costs and simplified maintenance requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
