This theory is demonstrated by three examples: the natural gas blowout when drilling in the permafrost, the hydrate cropouts in the seafloor and the gas bubbles in abyssal plumes. Then, several conclusions are drawn: there maybe exist the seeping and diffusing types of gas hydrate reservoirs which may still be growing in the Xisha trough, Dongsha continental slope of the South China Sea, west and south of Taiwan basin, and Bijianan basin; whereas in the Qiangtang basin of the Qinghai\|Tibet plateau may exist the regressive\|type gas hydrate deposit. Furthermore, the phenomenon of hydrocarbon gas leaking in the Qilian mountain areas and Junger basin indicates that these areas may ensconce gas hydrate reservoirs.

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.
