Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, particularly designed to be used 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 specific challenges to course of operators, including the risks related to the handling of a lethal, highly corrosive fluid which poses a possible hazard to plant gear, the people who work on website and the broader setting ought to leaks happen.
The process
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 critical security part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential dangers
The HF alkylation course of poses a variety of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in forged metal components that may ultimately cut back the life of pumps, valves and other equipment and worse nonetheless, lead to product leakage. เครื่องมือที่ใช้วัดความดันเลือด -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations nice importance on the choice of fabric of solid components, particularly in phrases of the pump casing and impeller.
Designed for resistance against highly corrosive fluids such as HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly designed to be used 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 technology and HMD Kontro, and utilizing an revolutionary growth process, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent technology pumps are options which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential for leakage into the setting, and lowering operational risks and the related costs to fulfill stringent environmental and well being and security objectives. Finally, there’s steady monitoring to ensure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety against dry pump operating (power management 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 provides vital safety, value and operational benefits. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
