Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Today (April 1st), reporters learned from **Pipeline Network** that the two compression units at the Quzhou compressor station on the West-East Gas Pipeline Project II have completed 72 hours of trial operation with gas turbines replaced by electric motors, and all performance indicators meet the requirements set by design standards. This marks the first successful implementation of such a conversion in China’s long-distance pipeline sector. The \"fuel-to-electricity\" conversion project for pipeline compression units involves replacing traditional gas-powered systems with high-efficiency motor-driven systems. As a result, the units no longer rely on natural gas as a power source, which reduces emissions, improves operational efficiency, and lowers maintenance costs. For this newly commissioned project, 2 18-megawatt motors, frequency converters, and related auxiliary systems were installed. The design pressure is 10 megapascals; all equipment used is of domestic manufacture. Meanwhile, the core components of the compressors were also upgraded, which further improved the operational efficiency, stability, and ease of maintenance of the unit. **Shang Fei, Deputy Manager of Zhejiang Gas Transmission Branch of Zhejiang Provincial Natural Gas Pipeline Network Company under the Pipeline Network Group: Once the project to convert the combustion engines in the compressors to electric power operation is completed, it will enable an 25% increase in the pipeline transmission capacity of the Nanchang–Shanghai branch of the West-East Gas Pipeline Project II. This is of great significance for further enhancing the pipeline network’s ability to ensure supply and handle emergency load adjustments in the Yangtze River Delta region. Compressor units are the key power equipment in long-distance natural gas pipelines. If natural gas pipelines are compared to the **‘major arteries’ of energy, then compressor units serve as the ‘heart’ that ensures the continuous delivery of natural gas. In long-distance transportation, a compression station generally needs to be built every 150–200 kilometers; these stations use compressors to increase the pressure of natural gas, thereby overcoming the resistance associated with pipeline transport and ensuring smooth flow of the gas. Fei: After converting the gas-driven units to electric-driven units in this project, natural gas consumption is reduced by about 35 million cubic meters per year, resulting in a reduction of carbon dioxide emissions of around 76,000 tons. Quzhou Station is the first station and an important hub on the Nanchang–Shanghai branch of the West-to-East Gas Pipeline Project II as it enters Zhejiang Province. The pipelines extending downstream cover areas such as Jinhua, Zhuji, Xiaoshan, Jiaxing, and Jinshan in Shanghai, and it also plays a key role in supplying natural gas to Jiangsu Province. Currently, Lines 1 and 2 of the West-to-East Gas Pipeline supply over 5 billion cubic meters of gas to Zhejiang Province each year, effectively meeting the energy needs for economic and social development as well as daily living.
