Recently, Sinopec Henan Oil Engineering Company underground operations company in the first application of confined acidification river technology success. The technology reduces environmental pollution, reduces the damage of the acidizing liquid to employees, realizes the cleaner production, solves the acidification problem and increases the injection rate.

Closed acidification technology is mainly used in the fully closed state of the acid, through the mechanical pump operation to maintain the liquid in a fully enclosed environment, from the acid tanker through the process of airtight acidification process equipment, injection 700 fracturing unit, pressurized after high pressure Manifold pump injection wells into the target layer of acidification, improve water injection effect, build a solid foundation for a stable yield. The entire construction of a total injection of acid liquid 45 cubic meters.


Integrated Refrigerated & Desiccant Air Dryer

Space saving: integrated design of dryer, filter, gas-water separator and suction dryer, saving space;

Energy saving: The design of three-in-one aluminum alloy heat exchanger minimizes the process loss of cooling capacity and improves the recycling of cooling capacity. Under the same processing capacity, the total red and green input of the modified model will be reduced by 15-30

High efficiency: the integrated heat exchanger is equipped with diversion fins, which is the uniform heat exchange of compressed air inside, and the built-in gas-water separation device is equipped with a stainless steel filter screen to separate the moisture more thoroughly.

Intelligent: Multi-channel temperature and pressure monitoring, real-time display of dew point temperature, automatic recording of accumulated running time, self-diagnosis function, display of corresponding alarm codes, and automatic protection of equipment.

Environmental protection: Corresponding to the international Montreal agreement, this series of models all use R134a, R410a, R407c environmentally friendly refrigerants, and the degree of damage to the atmosphere is zero, adapting to international market needs;

Stability: Standard configuration constant pressure expansion valve, standard configuration intelligent temperature control, laboratory test when the temperature reaches 65 ℃, ambient temperature reaches 42 ℃, flammable and stable operation, at the same time with temperature and pressure dual anti-freeze protection When the time is low, the output of the compressor is automatically stopped, and the aluminum plate is used to exchange the stored cooling capacity to provide heat exchange and energy saving, while extending the service life of the equipment.
