Example Embodiment
[0037] According to a preferred embodiment of the present invention, the first controller 41 is used to control: When the oxygen content of the exhaust gas outlet means 21 is less than 2% by volume, the evacuation means 21 and the exhaust recovery tail gas treatment unit 31 in communication, the tail gas pressure to the low-pressure system, and then sent to a downstream high pressure compressed gas system, and thus return to a high-value light hydrocarbons; when the exhaust gas outlet means 21 when the oxygen content is not less than 2% by volume, the suction means 21 communicating with the exhaust gas burning apparatus 32, through the logic control program, automatically switches to the sulfur incinerator exhaust gas, after sulfur incinerator flue gas temperature incineration emission concentration of VOCs in the 10mg / m 3 About to meet environmental emission standards. In this preferred embodiment, the oxygen content in the exhaust gas to achieve the accurate detection exhaust ...
