On February 25th, the Ministry of Ecology and Environment held a regular press conference for February and pointed out that the 14th Five-Year Plan indicator targets were set as five indicators: PM2.5, good days, NOx and VOCs, and heavy pollution days. VOCs replaced SO2 as With the new indicators, the state's emphasis on VOCs waste gas treatment has risen to a new level.
On February 25th, the Ministry of Ecology and Environment held a regular press conference for February and pointed out that the "14th Five-Year Plan" indicator targets were set as five indicators: PM2.5, good days, NOx and VOCs, and heavy pollution days. VOCs replaced SO2 as With the new indicators, the state's emphasis on VOCs waste gas treatment has risen to a new level.
VOCs have become the focus of the "14th Five-Year Plan" management and control. All localities and enterprises are constantly increasing their investment in VOCs waste gas treatment. Most companies achieve standard emissions by installing waste gas treatment equipment.
However, the composition of VOCs waste gas is complex, usually a variety of flammable and explosive mixed organic gases, and the inappropriate selection of the previous technical process or the professional management and control of the use of waste gas treatment equipment will often bring new safety hazards.
The 9 risks that may exist in the process of VOCs waste gas treatment are as follows.
(1) The enterprise changed materials and failed to carry out risk analysis as required.
(2) The closed operation of the oil storage tank may cause the breathing valve on the top of the tank to fail to work normally, increasing the safety risk of material storage.
(3) The airtight management of the production workshop may cause poor ventilation in the workshop, accumulation of escaping VOCs waste gas, and explosion accidents.
(4) The centralized collection of exhaust gas may cause different exhaust gases to react with each other, bringing new safety risks.
(5) In order to control the volatilization of oil and gas, closing the valve between the breathing valve on the top of the tanker and the tank body during transportation will easily cause the pressure in the tank to rise, and material leakage is likely to occur during pressure relief.
(6) The addition of waste gas treatment equipment often involves special operations such as hot work. If the management of waste gas treatment equipment is not in place, it is easy to cause fire and explosion accidents.
(7) Various safety risks are not fully identified in the renovation of exhaust gas treatment equipment, and the safety requirements of relevant equipment are ignored, and there is a risk of fire accidents caused by electrical sparks.
(8) The newly added waste gas treatment equipment has not undergone safety risk assessment and demonstration. For complex waste gas components, no safety risk analysis has been carried out and corresponding safety measures have been taken.
(9) Staff training is not in place, and there may be operational risks.
