How to deal with propylene leaks during production
Thread Content
The acrylic **incident in Nanjing some time ago was a painful lesson. Many companies likely have propylene as a raw material or in their products. What should be done if a propylene leak is detected immediately? In my opinion, management should be in place first, with emergency plans in place; employees should also receive regular training so that they are prepared to handle any propylene leaks. Anyone who notices any abnormalities at the site of the installation – such as hearing humming sounds near the propylene storage tanks and pipelines, seeing white mist, or smelling unusual odors – should immediately return to the control room, inform the team and the emergency response center. The emergency response center will then coordinate the deployment of firefighting and medical resources, while the team will organize personnel to handle the situation on site; in addition, the leadership should be informed as well. Regarding the method for handling propylene, I’ve heard that diluting it with steam is a good approach, and at the same time everyone must stop doing actions that can generate static electricity, such as using mobile phones. I posted this mainly to share experiences with everyone, including my own experiences and other methods for dealing with such situations. . .
Upon detecting an acrylene leak, it is necessary to immediately inform the shift team and the emergency response center. At the same time, the team members should set up protective barriers around the area to prevent unauthorized persons from entering. Attention should also be paid to the wind direction, with people avoiding positions downwind to prevent asphyxiation due to acrylene. Personnel should be assigned to dilute the acrylene using steam. During the handling process, personnel should wear cotton clothing; clothes that can generate static electricity must not be brought into the accident area, and mobile phones should be turned off.
First, identify the leak location and amount of leakage, then report to the plant dispatcher and the facility supervisor. Confirm whether to perform full parking isolation or partial isolation for pressure relief. The safety measures were described in great detail upstairs.
Steam dilution works well for large-scale liquid propylene leaks; fire water can also be used to dilute the gas phase. The key is to strictly control the generation of open flames, as well as to prevent static electricity from arising due to the friction between propylene and metal pipelines during the leak. It is also necessary to shut off the valves upstream and downstream of the leak site as quickly as possible. In the event of a large-scale leak, attention must also be paid to the wind direction, and personnel as well as uninvolved people should be evacuated through the pre-designed safety routes.
