The first use of jet pump to collect propylene

Recently, the smelting of polypropylene workshops changed the tradition of using water ring vacuum pumps to empty propylene for many years. The first use of jet pumps to collect propylene was successful. Not only can 130 tons of propylene be recovered annually, but also more than 100 million yuan in profits. It also avoided the impact of propylene gas venting on the atmosphere. Environmental quality has achieved a win-win result for both social and economic benefits.

It is understood that the use of a traditional single-end water ring vacuum pump will result in greater propylene waste and environmental pollution. The technical staff of the workshop has designed a set of jet pump collecting acrylic devices consisting of jet pumps, water pumps, air-water separation tanks and other multi-stage equipment. The device is simple in structure, easy to operate, and has a wide range of vacuum. It is suitable for pumping gas with granular media. Water is recycled by a centrifugal pump, which solves the problem of easy oxygen leakage during the vacuum process, thus realizing the venting of propylene. The gas is pumped to the gas cabinet for safe recovery.
