On June 10, the foundation formwork for the super-high tower structures related to Tianchen Company’s energy-saving and carbon-reduction integrated project in the caprolactam production chain at Yankuang Lunan Chemical Co., Ltd. was successfully delivered. The delivery of this batch of basic templates marks the beginning of the delivery of equipment for this project, serving as a milestone that indicates the project’s construction has entered a new phase. The base template is used for the embedding and positioning of anchor bolts for large-scale equipment; it must be delivered to the site during the civil foundation construction phase, as the delivery time has a direct impact on the project schedule. To meet the schedule requirements, Tianchen Company’s project team overcame various challenges and went all out, pressing the accelerator for quality and speed from the very beginning. They monitored the progress of the supplier’s design work and preparation of raw materials throughout the entire process, striving to minimize the manufacturing time while ensuring that all requirements were met. Through the integration and optimization of Lu Nan Chemical’s existing gasification, syngas, hydrogen, and high-quality coal chemical industry resources, this project has enabled the upgrading of the gasification infrastructure and cost reduction. It has increased the production capacity of the existing 300,000-ton caprolactam plant to 400,000 tons per year. Additionally, a 3,000-ton/day OMB multi-nozzle pulverized coal gasifier with independent intellectual property rights has been installed, along with supporting units such as shift converters, low-temperature methanol washing units, liquid nitrogen washing units, and ammonia synthesis units, all of which supply raw materials for the existing caprolactam plant ； The waste acidic gases generated by the plant are processed using advanced wet acid production technology to produce 98.5% concentrated sulfuric acid, which is used as a raw material for caprolactam ； The CO2 gas generated as a by-product of the facility is used, through advanced heat recovery technologies, to produce 200,000 tons per year of food-grade carbon dioxide ； The excess hydrogen is used in the 300,000-ton **, 165,000-ton aldehyde process, and 350,000-ton hydrogen peroxide plants within the complex ； The excess syngas with high CO content is used as feed gas for carbonylation, along with the construction of other auxiliary facilities.
