Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, including the risks related to the dealing with of a deadly, extremely corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on site and the wider surroundings should leaks occur.
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 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 continual tightening of clean fuels’ legislation has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
digital pressure gauge poses a quantity of severe environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in forged metallic components that can in the end scale back the life of pumps, valves and different tools and worse still, end in 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 selection of material of solid components, significantly by way of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids similar to HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed to be used in hydrofluoric acid alkylation units and were 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 know-how and HMD Kontro, and using an innovative growth process, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next era pumps are features which meet operator-specific needs for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply the mandatory resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the environment, and decreasing operational dangers and the related costs to fulfill stringent environmental and health and safety objectives. Finally, there is เพรสเชอร์เกจ monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety against dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to assist and maintain and no supporting methods, the latest magnetic drive sealless pump technology offers significant security, price and operational advantages. Lower end-user set up costs and simplified maintenance requirements, make it an efficient whole-life proposition compared to conventional mechanically sealed pumps.
