"It's on! It worked! ”On January 30, the air compressor station device site of Sanning Chemical Amide and Nylon New Material Project was boiling, and Luo Yan, manager of caprolactam area, was relieved and successfully won the first key node of the trial production monomer test run of the second phase of the amide plant, and fired the first shot of trial production, injecting strong impetus into the whole line of the second phase of the equipment in the first half of the year. 
This project is another 10-billion-level project of the company's transformation from traditional chemical industry to new chemical materials; It is another innovative project implemented by the company based on the independent research and development of the existing caprolactam plant and the major breakthrough in amide production process and technical equipment; It is another landmark project for the company to adhere to the "five development concepts", devote itself to improving the level of life and health with science and technology, and build a "high-quality development demonstration enterprise in the Yangtze River Economic Belt" with practical actions. The project was approved in August 2021 and started construction on November 20, 2021. According to the unified deployment of the company, the trial production of the project is led by the nylon company and jointly responsible for the project department. Since the determination of January 30, 2024 as the node for the commissioning and commissioning of the air compressor unit, the nylon company and the project department have conducted 5 discussions on the trial production progress nodes from the beginning of November to December 5, 2023, and finally determined the "Amide and Nylon New Material Project Construction Completion and Trial Production Operation Table", and scientifically formulated 21 key nodes from the delivery to the commissioning of the 12 sets of production devices. After the rectification of "three checks and four determinations" in the early stage, the maintenance of air compressors, the electrical wiring and power transmission of instruments, etc., the two air compressors gradually have the conditions for start-up.
On January 30, under the organization of Luo Yan, the trial production personnel conducted the last comprehensive inspection of the two 15000Nm h air compressor units, and further optimized the operation details according to the caprolactam air compressor start-up operation ticket.
At 13:35 on the same day, it was confirmed that the water, electricity, instrumentation and equipment were in a normal standby state, Luo Yan issued a start instruction, and Wang Zhenlin, a member of the project team, carefully and firmly pressed the start button of the air compressor A machine, as the roar of the machine changed from rapid to stable, the unit was successfully started, loaded and operated for two hours, the first, second and third stages of vibration were normal, and all parameters such as current were normal, and the start-up was successful! At 16:50, the air compressor B machine was successfully started, loaded and operated for two hours, the vibration of the first, second and third stages was normal, all parameters such as current were normal, and the start-up was successful! At present, according to the "Air Compressor Station Purging and Cleaning Plan", the caprolactam workshop has promoted the purging of the equipment pipelines of the air compressor station as planned, and has completed the purging of all equipment pipelines of the instrument air, compressed air and nitrogen systems, and completed the filling of purified molecular sieves. After the completion of the cryogenic nitrogen production cold box bare cold and pearlescent sand filling work, the air compressor station will have the conditions for trial operation.
