Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, 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 utility which poses specific challenges to course of operators, together with the risks associated with the handling of a deadly, highly corrosive fluid which poses a potential hazard to plant equipment, the people who work on website and the wider setting should leaks occur.
The process

HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a crucial security part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential dangers

The HF alkylation process poses a number of serious environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in solid metal parts that will in the end reduce the life of pumps, valves and other 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 great importance on the choice of fabric of cast components, particularly by way of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids similar to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed for use 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 leading licensor of HF alkylation expertise and HMD Kontro, and using an innovative development course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features

Built into the design of those next era pumps are options which meet operator-specific wants for the HF alkylation course of. 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 เกจวัดแรงดันเครื่องกรองน้ำ , the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the setting, and decreasing operational dangers and the associated costs to satisfy stringent environmental and well being and safety objectives. Finally, there could be continuous monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and protection against dry pump operating (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting systems, the most recent magnetic drive sealless pump expertise offers significant security, value and operational advantages. Lower end-user set up costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparison with conventional mechanically sealed pumps.
