Membrane separation nitrogen nitrogen injection device, mainly used in the oil field three oil production process, the device through to the oil well into the high-pressure nitrogen gas process, to achieve the purpose of improving oil recovery. The device adopts the vehicle moving mode, and the whole system is installed on the two trolley group, which is composed of five systems, such as an air compressor system, an air processing system, a membrane separation system, a nitrogen pressurization system and a central control system. The device directly extracts air from the atmosphere, separates the nitrogen from the air, and the nitrogen gas is separated from the air and can be used for high pressure and high purity nitrogen gas. 1 high pressure, large displacement, high efficiency. 2 high efficiency nitrogen recovery, reduce the power consumption of the engine, energy saving effect is remarkable. 3 nitrogen generated from the atmosphere, will not cause pollution to the air, soil and oil reservoir, has a great advantage in environmental protection. 4 the whole set of equipment has stable performance, which can be adapted to the harsh environment and extreme high and low temperature climatic conditions. Rated nitrogen flow 900Nm3/h, 1200Nm3/h Nitrogen gas flow rate 95% (adjustable between 90-99%) Rated nitrogen maximum output pressure 35*** Adapt to altitude Less than 3500m Adapt to the minimum ambient temperature -35 C Adapt to the maximum ambient temperature +45 C |
