Natural gas is a low-carbon and clean energy, and the demand is growing under the background of achieving carbon peaking and carbon neutralization in China. Natural gas purification is an important part of the development of conventional gas fields. The optimal operation of natural gas purification device, energy conservation and emission reduction, and green energy business expansion are of great significance for promoting natural gas production and green and low-carbon development of the industry. Taking the natural gas purification plants of PetroChina Southwest Oil & Gas field Company, which is the earliest in China, the largest in scale, advanced in process technology, fully equipped and highly automated, as an example, the operating status of the existing units and the challenges facing the difficult control of product gas quality indicators and rising operating costs were analyzed. In combination with the goals of carbon peaking and carbon neutralization, this paper gives the specific directions and suggestions on how to increase processing capacity, improve emerging technologies, continue energy conservation and emission reduction, innovate control systems and carry out carbon capture, utilization and storage and green energy business expansion.

The natural gas from the eastern line of China and Russia will soon be introduced into China, it will play a strong role in promoting the natural gas utilization projects in the northeastern area and also face various problems. In order to establish a long-term sustainable development resource supply system, combined with the actual situation of energy supply and demand, the future development direction of natural gas in Northeast China after the arrival of Russian gas is discussed in this paper. The main problems are analyzed as follows: the lack of self production and high dependence of outside the region; many choices of alternative energy by the regional characteristics; peak shaving difficult and the surplus hard to deal with; poor substitution economy and the price too high to bear. Some measures on the contradictions are summed up. Diversification of sources and resources can be ensured to sustainable development. It is clear that natural gas should be used as the transitional energy in Northeast China, and some suggestions on the utilization of natural gas for regional economic development are put forward.
