product description

oil and gasThe necessity of recycling equipment:

With the deterioration of the global environment and the increasing awareness of environmental protection, China has successively introduced a series of environmental protection policies, which mandate the installation of oil and gas recovery systems to recycle and utilize the volatile oil and gas from storage tanks, loading and unloading vehicles, ships and other transportation facilities, in order to prevent air pollution.

Customize according to requirements

To ensure the accuracy of the plan and quotation, customersProvide data on exhaust gas generation process, exhaust gas composition, exhaust gas concentration, exhaust gas volume, and required treatment effect(such as national standards), land area, etc.

Principle of Combination of Chemical Waste Gas Recovery Equipment（condensation+Adsorption process）

Will evaporate VOCS gas is introduced into the equipment cold box (with a condensation temperature set at -10 ° C)℃～-120℃）Other temperature zones can be customized for step-by-step condensation and liquefaction as needed. Part of the continuous production processes have implemented a dual switching process in the low-temperature section (after one side is blocked by ice, it automatically switches to the other heat exchange cold box for condensation, while the ice blocking side undergoes defrosting treatment)

Advantages of condensation

1. Stable processing effect, saving investment.
2. The unit occupies a small area and is not affected by environmental terrain.
3. No need to replace activated carbon, no need to deal with micro waste costs.
4. Compared to usingRCO, RTO and other incineration treatment processes, condensation method with no safe distance, and the whole machine is explosion-proof.
5. Waste gases from chemical and pharmaceutical industries can be condensed and recovered, with significant recovery benefits and high economic benefits.
6. Especially suitable for high concentrations and difficult to handle. Cannot be usedExhaust gas from RCO/RTO direct combustion and other working conditions.

productcharacteristic

1. The low load adsorption efficiency and stable properties of activated carbon ensure the long-term stable operation and high recovery rate of the equipment.

2. The desorption effect of the vacuum pump is strong, ensuring the efficiency of the equipment's cyclic use.

3. Using PLC control and frequency conversion regulation technology to achieve automatic control of the entire process of oil and gas collection, condensation liquefaction, oil-water separation, and transportation and storage of condensate oil. Adjustment of refrigeration units under variable operating conditions and economic operation of the system.

4. The process is simple, the safety is high, and the overall operation process is in a low pressure and low temperature state with minimal fire hazards; High level of automation control, easy to control and operate. The combination of condensation and adsorption processes utilizes the advantages of two methods, highlighting strengths and avoiding weaknesses, and scientifically combining them.

5. According to the different gas compositions, the lowest refrigeration temperature of the condensation system is -60 ℃, which truly achieves the goal of energy conservation and emission reduction without the need for deep cooling.
