  • Patent number: 11964243
    Abstract: An atomization generator and a special high-pressure atomization generation device for increasing oil and gas field recovery are provided. The special high-pressure atomization generation device for increasing oil and gas field recovery includes an agent pot assembly, a gear pump, a metering pump, an atomization generator and pipelines. The gear pump is connected with the agent pot assembly through an agent pot liquid inlet pipe. The metering pump is arranged between the agent pot assembly and the atomization generator which are connected through the low-pressure manifold pipeline and the high-pressure liquid inlet pipeline. The high-pressure liquid inlet pipeline is connected with the liquid inlet pipe. The liquid inlet pipes are connected with the metering pump. The gas inlet pipe is connected with the high-pressure gas source through the high-pressure gas inlet pipe. The gas inlet cap is provided with a gas inlet pipe.

  • Patent number: 8366957
    Abstract: The present application relates to a deicing composition, specifically to a chlorine-free deicing composition, comprising at least two active ingredients selected from glycerol, a glycol-type compound and a salt of an organic acid. The deicing compositions of the present invention contain no chlorine-containing material, are relatively less corrosive to concrete and carbon steels, and have no toxic effect on plants. Moreover, the deicing compositions of the present invention have high deicing efficiency, which is, according to the Chinese national standard GB/T23851-2009, up to 200% of the efficiency of sodium chloride or more. In addition, the deicing compositions of the present invention maintain a long-lasting deicing effect (e.g., a deicing effect for up to 3 hours).
