Abstract: There are many leakage points and disorderly volatilization of the medium in pontoon floating ceiling, which not only causes huge economic losses, but also brings serious potential safety hazards and environmental pollution problems. According to the Guidelines for the investigation of VOCs Pollution Sources in Petrochemical Industry and the related attachments issued by the General Office of the Ministry of Ecology and Environment, this paper estimates the edge sealing loss, floating ceiling accessory loss, floating ceiling joint loss and hanging wall loss by formula method. It puts forward the improvement measures for pontoon floating ceiling. According to the test data after putting into use, it is proved that the measures are effective.

Key words: pontoon floating ceiling, loss estimation, improvement measures
