Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, together with the dangers associated with the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on website and the wider environment should leaks occur.
เกจวัดแรงดันปั๊มลม combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a crucial security component that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh fuels’ laws has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential risks
The HF alkylation course of poses numerous severe environmental and health 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 elements that will in the end reduce the lifetime of pumps, valves and other gear and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice significance on the selection of fabric of forged components, notably when it comes to the pump casing and impeller.
Designed for resistance against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and utilizing an progressive improvement course of, the HMD Kontro HF pump includes 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 options
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory resistance to corrosion and also meets NDE requirements 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 environment, and decreasing operational dangers and the related prices to satisfy stringent environmental and well being and safety objectives. Finally, there is steady 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 techniques to help and maintain and no supporting methods, the most recent magnetic drive sealless pump know-how offers significant security, cost and operational benefits. Lower end-user installation prices and simplified maintenance necessities, make it an effective whole-life proposition in comparison with conventional mechanically sealed pumps.
