Although the development of China's natural gas industry started late, there is a certain gap with the advanced countries in the world. In order to speed up the pace of the development of industrial technology, we actively introduce foreign advanced technology. Over the years, we continue to explore in the actual operation of the gas station equipment selection and operation experience summary. Through the field investigation of domestic gas filling stations and air filling equipment, such as air compressor, dryer and so on, to understand the development trend of gas filling stations and the gap between them. Although the overall level of advanced countries is high, but the level of technology and development is not balanced.

The gas station construction is a complicated system engineering, system engineering principle only by thinking of the amount of the optimization of process design and equipment configuration, can make use of the limited funds, to provide advanced technology to users, to avoid wasting. To determine the parameters of air compressor and brand based on the number of gas pressure, gas required for cars; according to natural gas and water status and temperament of the local minimum ambient temperature, determine the structure of dehydration drying method and device type and specification; should be based on the technical parameters of air compressor based and on all aspects of the work pressure, gas flow rate and flow velocity, temperature, and the main parameters of the diameter and interface state of accounting, optimization and matching; in the process design is considered as far as possible the safe operation, convenient construction and easy maintenance etc..

Safety monitoring and protection measures including skid mounted structure, explosion-proof design, discharge system, emergency automatic shut-off valve, manual emergency brake valve, strong air cooling system, safety valve setting, control system, to ensure the safe operation of computer remote monitoring. The installation of equipment is an important work, and the installation quality is related to the life and safety of the equipment. Installation work should be carried out by the professional installation of technical personnel, equipment installation is mainly the installation of air compressors and pipe connections. The air compressor is the core equipment of the filling station, the installation requirements are very high, especially the basic level is required to ensure safe operation.
