Product Description
VOCs oil and gas recovery machine is the latest research and development of our company with the mission of saving energy, reducing emissions and optimizing the environment. It is aimed at chemical companies such as Sinopec, CNPC, CNOOC, Yanchang Petroleum and private petrochemical companies, involving terminals, refined oil storage, transportation and sales, packaging and printing. The series has condensation, adsorption, absorption, membrane separation and catalytic oxidation technologies, forming a variety of combined processes based on condensation and adsorption to ensure comprehensive treatment and recovery of VOCs and compliance with emissions.
Oil and gas recovery is a new energy-saving and environmentally friendly technology. The use of oil and gas recovery technology to recover oil and gas discharged during storage, transportation, loading and unloading, to prevent atmospheric pollution caused by the volatilization of oil and gas, or to convert oil and gas from gas to liquid, and to gasoline again. To achieve the purpose of recycling. Eliminate potential safety hazards, reduce economic losses by improving energy utilization, and obtain considerable returns. Common methods include adsorption, absorption, condensation and membrane separation systems.
1. Condensation technology
The principle of oil and gas condensation recovery: using the nature of different organic components in VOCs gas at different temperatures at different temperatures, the temperature of the system is reduced by the refrigeration unit stage, so that the vapor pressure of some hydrocarbons in the oil and gas reaches In the saturated state, the supersaturated steam gradually condenses into a liquid state and is collected to achieve the purpose of recovering oil and purifying gas. Using multi-stage condensation technology, the system temperature can be reduced to -75℃ through three-stage condensation. It is usually used in occasions with high organic gas concentration. The recovery effect is intuitive and the process is mature.
2. Adsorption technology
Adsorption recovery principle: The organic components in VOCs enter the pores of the adsorbent and are adsorbed by the difference in the binding strength between the components in the VOCs gas and the adsorption material. The method of recovering hydrocarbons in oil and gas by pressure swing or temperature desorption.
3. Absorption technology
Absorption principle: using low-volatile or non-volatile liquid as the absorbent, using the differences in the solubility or chemical reaction characteristics of various components in the exhaust gas, so that harmful components in the exhaust gas are absorbed by the absorbent, thereby achieving the purification of exhaust gas purpose.
4. Catalytic oxidation technology
The principle of catalytic oxidation technology: under the action of catalysts (Pt, Pd and other heavy metals), VOCs and O2 undergo oxidation reaction at low temperature (200~4009℃) to produce CO2 and IH2O.
The catalytic oxidation reaction equation is as follows:
CnHm + (n+m/4)O2 = nCO2 + (m/2)H2O + Q reverse heat
Compared with the ordinary direct combustion method for processing VOCs, this technology has the advantages of low ignition temperature and safe operation of equipment. For the treatment of low-concentration VOCs and the need to meet the current national emission standards, catalytic oxidation treatment technology is a more suitable treatment technology.
5. Low temperature plasma technology
Low temperature plasma is the fourth state of matter after solid, liquid, and gas. When the applied voltage reaches the discharge voltage of the gas, the gas is broken down, producing a mixture of electrons, various ions, atoms, and free radicals. Although the electron temperature is high during the discharge process, the temperature of the heavy particles is very low, and the entire system exhibits a low temperature state, so it is called low temperature plasma. Low-temperature plasma degradation of pollutants is the use of these high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas, so that pollutant molecules decompose in a very short time, and subsequent various reactions occur
To achieve the purpose of degrading pollutants.
6. Membrane separation technology
Membrane separation principle: Each component in the mixed gas is driven through the special membrane by the pressure, according to the microporous diffusion mechanism and dissolution-diffusion mechanism of the porous membrane, the separation purpose is achieved under the condition that the membrane transfer rate is different.

Flame arresters are installed before and after roots blower, before and after vacuum desorption pump, before and after balance pipe at inlet of oil collecting tank and fan. Five flame arrestors are installed inside the equipment to ensure the safety of equipment operation. | ||
The cold capacity of oil and gas can be all recycled by multi-stage regenerative heat exchange of low-temperature oil and gas in the system;Oil cooling recovery device is set in the oil tank at the bottom of each stage heat exchanger and on the oil outlet pipeline, which solves the problem of oil cold recovery; All the refrigerating capacity of the equipment is used to overcome the latent heat of vaporization of oil and gas, and there is no waste of excess cooling capacity. At the same time, the refrigeration efficiency of the compressor is improved and the ice blockage of the pipeline is effectively prevented. | appears in a low temperature state, which can not improve the refrigeration efficiency of the compressor, and the pipeline in this section is quickly blocked by ice. | |
Heat exchanger structure: vertical spiral tube type； Oil return: the flow direction is from the top to the bottom, and the oil return of the refrigeration system is smooth; anti ice blockingAnti corrosion:All pipes are made of 316L stainless steel,The shell is made of 304 stainless steel,It avoids the corrosion of chemical products to the heat exchanger, solves the problem of compressor oil return, and realizes the self elimination of cold and hot stress. Quality:Automatic coil welding improves welding quality and reduces leakage points； | Other types of heat exchanger can not eliminate the cold and thermal stress, and the leakage of refrigeration system is easy to form in the alternating process of low temperature refrigeration and high temperature defrosting. The heat exchanger is made of ordinary metal material, which has poor corrosion resistance | |
Pneumatic moving parts | Roots blower with constant back pressure is uesd,to ensure that the outlet pressure of the fan is constant in the process of automatic frequency conversion operation according to the intake Air volume. | The centrifugal fan is used in the system, and the outlet pressure of the fan cannot be guaranteed in the process of automatic frequency conversion operation according to the intake Air volume. |
time Anti ice blockage of gas path | For the single way cold storage system only used for vehicle loading, the flexible ice retarding design is adopted to ensure that the low-temperature cold field can operate continuously for more than 12 hours without ice blockage;Each level is equipped with an automatic defrosting device, which can automatically melt the ice at each level of the equipment during the user's shift or off-duty time. The ice melting time is short (only 25 minutes), and the water after ice melting is discharged through the oil-water separator in the equipment, without ice blockage. It takes only 25 minutes for the refrigeration system after ice melting to resume the cold field automatically In order to ensure the continuous operation of oil and gas recovery equipment and benzene recovery equipment for wharf loading and tank top gas recovery, the refrigeration system adopts the structure of double low temperature cold field controlled by single refrigeration compressor.When one cold field is close to ice jam, the refrigeration system will automatically divide 1 / 6 cooling capacity to pre cool another low temperature field. When the temperature of the other low temperature field drops below - 55 ℃, all cooling capacity and gas path of the equipment will automatically switch to another low temperature field; at the same time, the original low temperature field will defrost automatically by the exhaust of compressor, and the cold field will be in standby state after defrosting. At present, Only our company is using it | There is no flexible delayed icing design. When the continuous operation of the equipment is less than 12 hours, the low-temperature field is seriously blocked by ice, and the automatic ice melting technology is not mature, so it is unable to melt ice quickly and ensure long-term continuous operation. There is no such structure of the single refrigeration compressor automatically controlling the two-way low-temperature cold field，so the equipment can not be used continuously .If two-way refrigeration compressor is used to automatically control the structure of two-way low-temperature cold field,，Under the same distribution power，The actual cooling capacity of each cooling field is only half of that of the double cooling field controlled by a single refrigeration compressor. |
There is no absorption system, which can not effectively absorb C2, C3 and other light components after adsorption and desorption. This component can only be accumulated more and more in the system, resulting in dead circulation and illegal emissions in the system, which can not achieve real environmental protection | ||
An oil-water separator is installed at the lower part of the first oil gathering tank, and the water generated by the system is separated here in any way; The oil output from the second oil tank and oil pump does not contain any moisture, which ensures that the oil outlet pipe is not blocked by ice in winter. | The oil-water separator is only set up at the outlet pipe of 4 ℃ temperature field, and the water produced after defrosting in low-temperature field can not be separated, and the pipeline is seriously blocked by ice in winter. | |
poisoning device | It has a cyclone oil / gas separation system. Once the oil outlet pipe at the bottom of the cold field is blocked, the condensed oil will be blown into the oil / gas separation system by the air pump to realize oil-gas separation, and the separated oil will enter the oil gathering tank smoothly | This device is not designed in the system, so once the oil outlet pipeline is blocked by ice, the condensed oil will be blown into the activated carbon adsorption system by air pump, resulting in activated carbon poisoning |
transportation system for recovered oil | As the recovered oil is light oil, it is difficult to transport it out by oil pump alone. Therefore, our company has developed an automatic conveying device for condensing and recycling volatile substances and obtained an invention patent (Patent No. 201010298978.2). The double tank pressurized transportation ensures the reliable transportation of oil products and does not affect the normal collection of oil products. The equipment is equipped with a metering oil meter to measure the oil transported in real time, and has double measures to prevent oil backflow. | There is only one oil tank in the system, so it is difficult to ensure reliable oil transportation and normal oil collection at the same time. |
intellectual property rights | It has 12 invention patents, more than 40 utility model patents and software copyrights, including Oil and gas recovery system,Methods of controlling suction temperature of compressor in low temperature refrigeration system,Automatic conveying device for condensing and recovering volatile substances,Two stage cascade refrigeration method for oil and gas recovery, so as to ensure no intellectual property disputes. |
