Sealless pump design tackles HF alkylation

pressure gauge weksler ราคา that includes new technologies, particularly 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 particular challenges to process operators, including the dangers related to the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant gear, the people who work on website and the broader environment ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a critical security element that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential risks
The HF alkylation process poses a number of severe environmental and well being and safety 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 assaults imperfections in solid metallic parts that may in the end cut back the lifetime of pumps, valves and different tools and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of fabric of cast parts, particularly when it comes to the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation models and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and using an revolutionary development process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing หลักการทํางานของpressuregauge of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent era pumps are features which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been proven to supply the required resistance to corrosion and likewise meets NDE requirements 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 related prices to satisfy stringent environmental and health and security goals. Finally, there is steady monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump working (power control monitor).
With no seals to leak, no seal buffer systems to assist and maintain and no supporting methods, the latest magnetic drive sealless pump expertise provides significant security, price and operational benefits. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
