Process route of factory system: 
The process flow of the unit system is shown in the figure above (process flow diagram attached):
1. The oil and gas discharged from each oil and gas outlet will be collected into the gas gathering main pipe; 2. The pressure sensor on the main gas gathering pipe feeds back the pressure signal to the control system; 3. The control system regulates the pumping capacity of variable frequency air pump through frequency converter, Timely tracking the exhaust velocity of oil and gas; 4. The collected oil and gas are transported to the oil and gas recovery unit.In the condensation unit,By means of gradient condensation,Most of the oil and gas are converted into liquid oil and directly recovered to the storage tank of the unit. After the separation, the low concentration oil and gas are regenerated and exchanged with the inlet gas to near normal temperature and enter the later stage adsorption unit; 5. The low concentration and near normal temperature oil and gas from the heat exchanger continue to enter the adsorption unit. The adsorption unit is mainly composed of two parallel tanks (tank a and tank B) and pneumatic valves. Low concentration oil and gas pass through the adsorption layer from bottom to top, and the easily adsorbed oil and gas are adsorbed and separated by adsorbent, and the clean gas at the end of adsorption is directly discharged to the standard through the flame arrester; 6. The adsorption tank which reaches the set adsorption time enters into the desorption process (including two processes of desorption and purging). At the same time, another adsorption tank in parallel enters the adsorption process, and the analyzed high concentration gas enters the front stage condensation unit for the next "condensation adsorption" treatment process; 7. When the oil collecting tank reaches the set level, it is automatically transported to the storage tank designated by the user through the oil pump.
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.
Our Advantages
Product recovery efficiency: The vapor recovery efficiency of the equipment condensing module can reach more than 90%. The equipment has its own oil storage tank. After the recovered oil is separated from oil and water, it is delivered to the owner’s designated storage tank or oil pipeline through the equipment’s own oil pump. The equipment comes with a liquid flow meter and sight glass, which can intuitively understand the effect of recovered oil and record and save the recovered amount in the program.
The advantages of our company's products are compared with other companies' products.

Security system
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.

There is only one flame arrester installed in the air inlet, so the Security is very poor.

Energy saving system
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.

There is no Oil cooling recovery system,When the oil leaves the cold field of the equipment and enters the oil collecting tank, it
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
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 
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.

Continuous operation
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.

Absorption system

It has its own oil absorption system to effectively absorb C2, C3 and other light components after adsorption and desorption.
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

Separation of oil and   water system
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.

Anti adsorbent
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
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.
