China’s first high-sulfur compressor unit debuts at Sinopec Puguang Gas Field

Thread Content

Recently, the high-sulfur compressor unit independently developed by Petrochemical Machinery successfully completed a 72-hour load test operation in the Puguang Gas Field. All operating parameters and performance indicators were good, and customers fully recognized it. This is also the first high-sulfur compressor unit successfully developed in China. High-sulfur compressors have high requirements for corrosion resistance, sealing, and safety. They are high-end products among natural gas compressors and were previously dependent on imports. Petrochemical Machinery insists on "securing the energy rice bowl" and has successively overcome difficulties such as structural design, corrosion-resistant materials, welding processes, and complete machine testing. It has mastered the core technology and independent intellectual property rights for the development of high-sulfur compressors, and solved problems such as corrosion resistance, leakage prevention, safety, and reliability. It is the first in China to master the R&D and manufacturing technology of compressors suitable for operation in natural gas environments containing more than 8% hydrogen sulfide. During the on-site debugging process of the high-sulfur compressor unit, two engineers from Petrochemical Machinery wore protective equipment and were on duty 24 hours a day. They stepped up debugging and monitoring, and promptly checked and rectified the unit to avoid "accidents" in special environments to the greatest extent. Before the no-load test, they carefully checked the start-up procedure of the compressor unit, whether the oil circuit was normal, the bolt tightening status of each part, the bearing gap, the motor alignment, etc., tested each valve at a single point, and used nitrogen to perform air tightness leak tests on each part to ensure that no-load conditions were met. During the 72-hour loading test of the compressor, they patiently recorded the data of the unit's operation and conducted inspections every 2 hours, ensuring that the on-site industrial test was a complete success. The promotion and application of domestic high-sulfur compressor units will provide core equipment support for the development, stable production and increase of sour gas fields in my country.
