The processing capacity,concentration of oil and gas discharged and efficiency of oil & gas processing of equipment was 650 m~3/h,14 g/m~3 and 97% respectively,which met the"Discharge Standard of Atmosphere Pollutants for Gas Storage"(GB20950- 2007).

In this paper, with the reference to the velocity of discharge, the average emission concentration and the emission characteristics of the gaseous pollution sources, three sampling methods: integral method, integration by parts and finite summation approximation are derived, which are employed in monitoring of pollution sources.

The renovated precipitator has considerably improved dust removal of the machine with dust emission concentration lower than 150mg/m 3 , the standard limit regulated by the national standard of air pollutants emission for cement plant.

An on-the-spot test on the emission concentration of cooking fume was made with two different methods and analysis done on its components by sampling experiment method.

The variation curves of oil expulsion concentration in source rocks were given,which indicated that oil expulsion concentration was controlled by viscosity of oil,saturation and relative permeability of oil and water in the source rocks.
