The technology of monitoring and tracing the unorganized emissions of VOCs in petrochemical parks is a research hotspot. For the VOCs leakage in the pump room of the aromatics extraction equipment, 6 distributed monitoring points are implemented to monitor the VOCs concentration. A 2-hour leak test is performed using n-hexane standard gas, and the process is simulated using computational fluid dynamics. The results show that there is a background value of n-hexane concentration in the pump room, which means that potential leakage occur. P36, P19, P18, and P15 were able to respond to the n-hexane leak, but the concentrations of P14 and P17 y did not increase. The leakage sequence of simulation is the same as that obtained in the experiment. The concentration distribution is affected by the wall barrier and distance, and n-hexane will preferentially diffuse along the wall.
