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 course of operators, together with the dangers associated with the dealing with of a deadly, highly corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on web site and the wider environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a crucial security component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of clean fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential dangers
The HF alkylation course of poses a quantity of serious environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in solid metallic elements that can in the end cut back the lifetime of pumps, valves and other tools and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places great importance on the choice of material of solid parts, significantly in phrases of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids such as HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use in hydrofluoric acid alkylation models and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an revolutionary development course of, the HMD Kontro HF pump contains a excessive 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 these subsequent generation pumps are options which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been confirmed to supply the required resistance to corrosion and in addition meets NDE necessities for HF acid. In เครื่องมือวัดความดันคือ , the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential for leakage into the surroundings, and reducing operational risks and the associated prices to fulfill stringent environmental and well being and security objectives. Finally, there’ ชนิดของpressuregauge monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and safety in opposition to dry pump operating (power management monitor).
With no seals to leak, no seal buffer systems to support and preserve and no supporting systems, the newest magnetic drive sealless pump technology presents vital security, cost and operational advantages. Lower end-user installation prices and simplified maintenance requirements, make it an effective whole-life proposition in comparison with standard mechanically sealed pumps.
