Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new technologies, particularly designed to be used 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 process operators, together with the dangers related to the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the people who work on site and the wider environment should leaks happen.
The course of

HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important safety component that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh fuels’ laws has elevated the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential dangers

The HF alkylation process poses a quantity of critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in forged metal parts that will ultimately scale back the lifetime of pumps, valves and different tools and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of fabric of solid elements, notably in phrases of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use in hydrofluoric acid alkylation units and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump

The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump includes a excessive 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 next technology pumps are options which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to offer the necessary resistance to corrosion and also 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 environment, and lowering operational risks and the related prices to fulfill stringent environmental and well being and security goals. Finally, there’s steady monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and protection in opposition to dry pump operating (power management monitor).
With เกจ์วัดแรงดันน้ำมันเครื่อง to leak, no seal buffer methods to support and keep and no supporting systems, the latest magnetic drive sealless pump know-how presents significant security, value and operational benefits. Lower end-user set up prices and simplified maintenance necessities, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
