Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes 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 related to the handling of a deadly, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on website and the wider environment should leaks happen.
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 provide alkylate. A high-octane additive, alkylate is a crucial safety element that offsets the high vapour stress 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 liable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
เกจวัดแรงดันน้ําไทวัสดุ poses a variety of severe environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in forged metal parts that may in the end reduce the lifetime of pumps, valves and different gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places nice significance on the choice of material of cast elements, particularly 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 provide total containment with built-in reliability. เกจ์วัดแรงดัน featuring new technologies have been particularly designed to be used in hydrofluoric acid alkylation items and have been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and utilizing an innovative growth process, the HMD Kontro HF pump features 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 these next technology pumps are options which meet operator-specific needs for the HF alkylation course of. They include a pump casing in Alloy C22 materials, which has been confirmed to supply the required resistance to corrosion and also 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 reducing operational dangers and the associated costs to meet stringent environmental and health and safety goals. Finally, there is steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer techniques to support and keep and no supporting systems, the latest magnetic drive sealless pump expertise provides vital safety, cost and operational advantages. Lower end-user installation costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
