The polluting status of total hydrocarbon in the atmosphere influenced by petrochemical enterprise is described. The control measure was proposed by analyzing the cause of the pollution.
Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year.
意外污染透过碳氢化合物明显减少，只代表一小部分废物透过脱气估计为每年1.5至300万吨石油。
