Foundation of energy benchmarking system for CNG station

Taking the production and sales of CNG in PetroChina Southwest Oli and Gasfield Company as example, the article analyzes the present situation of energy consumption of CNG devices and important factors affecting energy consumption in the important process. Through comparative analysis and screening, the index of benchmarking can be determined, and the system of energy efficiency benchmarking in CNG production and sales business has been established preliminary. It is clearly that the measures of energy-saving and potential-excavating can be formulated in preliminary, and the value of energy-efficiency can be gotten through calculation with the field energy consumption data of 3 CNG stations, and a comparison can be made, finally a disparity can be found out.
