In order to study on the unorganized emissions characteristics of volatile organic compounds (VOCs) of Tianjin chemical industry, three plants located in a chemical park in Tianjin were chosen. Air samples on the plant boundary and within the enterprise were collected through air bag, and the VOCs emission levels and component characteristics were measured using proton transfer reaction time of flight mass spectrometer (PTR-TOF-MS). The analysis results showed that, (1) the emission level of VOCs of three plants were different. The level of VOCs in tank area was directly related to the tank type, and the level in storage tank area was related to whether it was sealed, (2) the components of VOCs emitted from unorganized sources mainly were saturated alkanes represented by C2, C2, C8, C9 and C11 and oxygenated volatile organic compounds (OVOCs) represented by CH4O, (3) it was found that alkane substance was a large class of VOCs component in chemical industry plant, so alkanes should be controlled in priority.
