Emergency response to butadiene sphere tank incidents

Environmental risk assessment of storage tanks: It mainly covers the potential environmental risks associated with 50,000-ton butadiene storage tanks during storage, as well as the calculation results, quantitative data, and preventive measures. http://bbs.hcbbs.com/viewthread.php?tid=334322

During storage and transportation, butadiene can leak due to inadequate sealing at the connections; moreover, the formation of water within the material can cause the sealing parts such as flanges to crack, leading to material leakage. 1) Main measures taken for initial accident control: In the event of a fire, it is necessary to use fire extinguishers, fire hydrants, and fire monitors on site to put out the fire, while also calling the fire department; the operators must cut off the supply and flow of materials. After the fire is extinguished, use fire pumps and fire hydrants for coverage. 2) Emergency process handling for the upstream and downstream systems: In the event of a leak and fire in the spherical tank, quickly close the inlet and outlet valves of the tank ； Open the valve of the heat discharge pipeline at the bottom of the tank, the butadiene valve at the fire wall, and increase the opening of the heating steam valve for the heat discharge tank. After the liquid phase material is emptied, open the vent valve on the tank top to vent the gas phase. The butadiene pump leaked and caught fire; the pump was shut down, the upstream and downstream valves were closed, pressure was relieved through a flare valve, and the fire was extinguished using dry powder fire extinguishers, fire monitors, and fire hydrants. 3) Additional notes on potential accidents in this unit: In the event of a leak and fire at the flange of the flow meter, stop feeding material. The personnel on duty should use on-site fire extinguishers, fire hoses, and fire hydrants to put out the fire. After the fire is extinguished, use fire hoses and fire hydrants for protection while contacting someone to secure the leaking area; if it is not possible to secure it, a special handling plan should be developed and followed. Leaks at welds, flanges, and valves on the process pipelines, as well as leaks at the connections of auxiliary devices such as Bourdon tube pressure gauges, require that the valves at both ends of the pipeline be closed in order to cut off the flow and control the source of the leak.
