Application of Propane Refrigeration Unit in Treatment of Refinery Exhaust Gas VOCs

1. background introduction

With the rapid development of industrialization, the emission of volatile organic compounds (VOCs) in refinery waste gas is becoming more and more serious, which poses a great threat to the environment and human health. As a mature process equipment, propane refrigeration unit has a wide application prospect in the field of waste gas treatment.

Sources and hazards of 2. VOCs

The VOCs in refinery waste gas mainly come from various process links in the refining process, such as oil and gas recovery, tank respiration, etc. These VOCs not only pollute the environment, but also may cause harm to human health, such as irritating the respiratory tract and damaging the liver.

Working principle of 3. propane refrigeration unit and its application in VOCs treatment

The propane refrigeration unit reduces the temperature through the refrigeration cycle, so that the VOCs in the exhaust gas are adsorbed or condensed at low temperature, so as to achieve the purpose of purifying the exhaust gas. In the treatment of refinery waste gas, propane refrigeration unit is mainly used in tail gas treatment, oil and gas recovery and other links. By reducing the exhaust gas temperature, the VOCs are converted into a liquid state, which is convenient for collection and treatment, and effectively reduces the VOCs content in the exhaust gas.

Advantages of 4. Propane Refrigeration Unit in Treatment of VOCs

1. Efficiency: Propane refrigeration unit can effectively reduce the exhaust gas temperature, so that VOCs quickly condensed.

Flexibility: It is suitable for waste gas treatment in different process links, and the refrigeration temperature can be adjusted according to actual needs.

Environmental protection: effectively reduce the VOCs content in the exhaust gas and reduce environmental pollution.

4. Economy: Compared with other treatment methods, the propane refrigeration unit has lower operating cost and convenient maintenance.

5. case analysis

A refinery uses a propane refrigeration unit to treat VOCs in the exhaust gas. After treatment, the VOCs content in the exhaust gas is significantly reduced, reaching the national emission standard. At the same time, the equipment shows the characteristics of high efficiency and stability in the operation process, which brings significant economic and environmental benefits to the enterprise.

6. Conclusion

Propane refrigeration unit has important application value in the treatment of VOCs in refinery exhaust gas. By reducing the exhaust gas temperature, the VOCs are condensed, collected and treated, and the VOCs content in the exhaust gas is effectively reduced to meet the environmental protection requirements. In the future, with the continuous progress of technology, the application prospect of propane refrigeration unit in the field of waste gas treatment will be more broad.
