How to choose organic tail gas treatment device manufacturers? From gas station oil depot to chemical plant

The scene of 1. organic exhaust gas is more than you think.

Gas stations unload oil, store oil and refuel, gasoline volatilization is oil and gas; The storage tank of the oil depot discharges a large amount of oil and gas once it is sucked. The exhaust of chemical plant reactors, storage tanks, centrifuges and vacuum pumps is full of various organic solvent vapors. Toluene, xylene, methanol and DMF in pharmaceutical factories volatilize as much as they use. In the printing, coating and adhesive industries, ester, ketone and aromatic solvents waste gas are found every day.

The scene is not the same, the exhaust temper is not the same. Gas stations have high oil and gas concentration and strong intermittency; chemical plants have complex components and may have corrosive media; pharmaceutical plants have large air volume fluctuations and many types of solvents. Therefore, a qualified manufacturer's product line should be able to cover multiple scenes and processes, but only one kind of equipment can be used.

2. see product line width

Take Luoyang Wo Hong as an example, the product system covers all the way from the gas station depot to the industrial factory.

1. Gas station, oil depot oil and gas recovery device

In the three oil and gas recovery scenarios, Wohong has a membrane separation process with a treatment capacity of 2-20m ³/h, and has two configurations of "air-cooled membrane separation" and "single membrane separation.

-Air-cooled membrane version, power 2.7kW, processing capacity 4-20 m/h, noise ≤ 75dB, complete machine about 410kg;

-Combined pump version, single membrane, power only 1.3kW, noise ≤ 63dB, about 390kg, suitable for stations sensitive to energy consumption and noise.

The installation is completed in one day, the pipe clamp is connected, the explosion-proof box is not connected, the unattended operation is automatic, and the recovered oil is directly returned to the tank and then sold. The life of the membrane module is more than 10 years, there is no solid waste liquid, and the operation and maintenance cost is low.

2. Top gas recovery device for oil depot and storage tank

Volatile oil and gas in storage tanks are adsorbed by compression condensation + carbon. For a 50 m/h oil depot project, the treatment efficiency is ≥ 95%, the emission concentration of non-methane total hydrocarbons is ≤ 120 mg/m, the energy consumption is about 30kW, the skid-mounted integrated full-automatic, the tank top pressure grading interlock, the high pressure automatic start, the low pressure automatic shutdown, and the oxygen content interlock protection.

3. Industrial VOCs treatment device

Chemical, pharmaceutical industry, provide compression condensation membrane separation, cryogenic carbon adsorption, membrane separation coupling a variety of combinations, processing capacity from tens to thousands of cubic meters per hour.

-Cryogenic + carbon adsorption, suitable for high concentration and high boiling point tail gas, double-channel anti-icing blockage, recovery rate ≥ 98%;

-Compression condensation + membrane separation, suitable for esters, alcohols, aromatic hydrocarbons and other solvent tail gas with recovery value, the recovery rate is ≥ 95%, and the emission is far below the national limit;

-Pharmaceutical industry customization, methanol, toluene, DMF, dichloromethane and other multi-component resin adsorption, corrosion-resistant materials, 72 hours of trial operation acceptance.

4. Self-produced core components,gas separation membraneComponent

Membrane module is the heart of membrane separation equipment. Wohong constant temperature and humidity dust-free workshop has an annual production capacity of more than 1.2 million square meters of membrane materials and an annual production capacity of 30000 membrane modules. 3-inch, 4-inch, 6-inch and 8-inch roll-type membrane modules are all made. Organic gas recovery, oil and gas recovery and nitrogen production (purity 99.5) are all used. The core components are produced by themselves, with controllable quality, guaranteed spare parts and higher cost performance.

What do you see in 3. performance? Look at landing projects.

Judging manufacturers depends on unreliable performance, which is the most direct.

-Long-term service to many provincial and municipal sales branches of PetroChina and Sinopec, winning batch orders and framework contracts for oil and gas recovery equipment for many times, and supplying hundreds of sets in recent years;

-The industrial field covers pharmaceutical, chemical, oil storage and transportation, oil depot tail gas recovery, benzene vapor recovery in pharmaceutical plants, methanol tail gas recovery in chemical plants and other landing projects;

-Customers are located in more than 20 provinces and regions across the country, and cross-regional delivery and after-sales are no problem.

4. after-sales ask these four things

VOCs treatment equipment long-term operation, after-sales than the equipment itself is also important.

1. Warranty period. How long is the warranty of the whole machine? Is there a longer warranty for the core components of compressor and membrane module? The warranty period of compressor and membrane module in some projects of Wohong is 24 months, which is longer than the industry routine.

2. Response speed. How long does the fault respond and how long does it arrive. Wo Hong has a 4-hour response to the 24-hour arrival of the project caliber, and a 12-hour response to the 48-hour arrival of the standard caliber.

3. Long term service. After the warranty period, there is no lifelong technical support, long-term supply of spare parts, regular free inspection.

4. Training. Whether the operators have theoretical and practical training, and whether the on-site personnel can operate and maintain independently.

5. Finally

Organic tail gas treatment is not just a matter of buying a piece of equipment, but a systematic project of selecting technology, equipment and manufacturers. Complete product line, self-produced core components, solid performance, after-sales in place, the project can be long-term stable compliance, volatile solvents can become real income.

Luoyang Wo Hong, focusing on oil and gas recovery and organic gas recovery and processing, serving PetroChina, Sinopec and many industrial enterprises. Gas station oil and gas recovery, oil depot tail gas treatment, factory VOCs treatment, there is a need to call for advice, according to the working conditions to customize the program.
