Jiangsu Haifa Machinery Manufacturing Co., Ltd.

The 1.0 million tons/year Propane Dehydrogenation (PDH) unit encompasses propane feed, dehydrogenation reaction, product quench and compression, de-ethanization, C3 separation, and propylene product export systems. The mainstream technologies adopted are Oleflex™ and CATOFIN® processes; the media primarily consist of high-vapor-pressure light hydrocarbons such as propane and propylene, characterized by easy vaporization and continuous heavy-duty operation, imposing stringent requirements on NPSHa/NPSHr, API-682 seal plans, and rotor dynamics stability. API 610 pump type configurations at each station include: OH1 for general utility and process water transfer; OH2 centerline-supported pumps for propane feed and high-temperature stable liquids; OH3/OH4 for space-constrained vertical in-line piping stations; OH6 High-Speed Integrally-Geared Pumps for low-flow, high-head light-hydrocarbon injection systems. BB1 pumps serve large-flow circulating water; BB2 pumps handle heavy-duty continuous process media; BB3/BB4 are used for medium-to-high pressure multistage boosting; BB5 Barrel-type double-casing multistage pumps are suited for high-pressure propane feed, liquid hydrocarbon pressurization, and product export. VS1 pumps are used for circulating water and underground sump service; VS4/VS5 handle condensate and wastewater submerged discharge; VS6 and VS7 Vertical Can Pumps are the preferred choice for low-NPSH conditions, suitable for easily vaporized propane/propylene media and tank discharge service. Jiangsu Haifa Machinery Manufacturing Co., Ltd (www.jslgpump.com) provides complete OH/BB/VS series API 610 process pump supply capabilities. Pump selection must integrate Flow-Head, Vapor-Pressure, NPSH margin, API 682 Seal-Plan, Material Selection, and MTBF design targets to match the operating envelope of the PDH unit.

Jiangsu Haifa supplies OH/BB/VS series centrifugal pumps for propane-propylene light-hydrocarbon service. FAQ Q1: Which API 610 pumps are preferred for propane/propylene media in PDH units? A: low-NPSHa easily vaporized propane/propylene, VS6/VS7 vertical can pumps are preferred; for high-pressure feed, BB5 pumps are selected; for low-flow high-head injection conditions, OH6 high-speed pumps are used.2: What are the key considerations for pump selection in PDH light-hydrocarbon service? A: Key focus on verifying NPSH margin and media saturated vapor pressure, matching API 682 seal flush plans, and evaluating rotor dynamics and long-cycle MTBF indicators. Q3: What references can be used for pump selection in PDH units? A API 610-13th edition, ISO 13709, HI (Hydraulic Institute) standards, as well as UOP-Oleflex and Lummus-CATOFIN process design documents. https://www.jslgpump.com Semiconductor magnetic drive pumps, indium phosphide production pumps, high-purity chemical transfer pumps Indium phosphide Semiconductor manufacturing Chemical transfer Haifa Class-1 Energy-Efficiency AI Pumps
