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 dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses explicit challenges to process operators, including the risks related to the dealing with of a lethal, highly corrosive fluid which poses a possible hazard to plant tools, the individuals who work on website and the broader environment should leaks occur.
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 provide alkylate. A high-octane additive, alkylate is a crucial security element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of clean fuels’ laws has increased the demand for alkylate, which can be answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of poses a number of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in forged steel elements that may finally scale back the lifetime of pumps, valves and different gear and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great importance on the choice of fabric of cast elements, significantly when it comes to the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. pressure gauge nuova fima ราคา that includes new technologies have been specifically designed for use in hydrofluoric acid alkylation items and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an innovative 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 tested utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next technology pumps are options which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 supplies, which has been confirmed to supply the necessary resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the risk of leakage into the surroundings, and decreasing operational dangers and the related prices to meet stringent environmental and well being and safety targets. Finally, there is steady monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting techniques, the latest magnetic drive sealless pump expertise provides vital security, value and operational benefits. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to conventional mechanically sealed pumps.
