Production Technology Department of Shaanxi Coal Group: Deepening and Strengthening Production Management to Achieve Low-Carbon, Green Development and Improved Efficiency. Author/Source: Shaanxi Coal Group. Date: 2022-02-10. Clicks: 17. In 2021, the company’s level of production organization continued to improve, with its product output achievement rate ranking first among the chemical sector units of Shaanxi Coal Group. All three boilers have accumulated operating times of over 350 days each; the slurry concentration has remained stable at above 63.5%. The operation cycle of the gasifier burners has exceeded 70 days, the synthetic ammonia System B has been in continuous operation for 567 days, the daily production of phosphoric ammonium nitrate has reached 1,200 tons, the monthly production of PT has surpassed 5,500 tons, and the monthly production of BDO has exceeded 12,000 tons... These new historical records not only represent full recognition of the efficient operation of the production systems over the past year but also set higher goals and requirements for the new year ahead. In 2022, the Production Technology Department will continue to focus on the core principle of \"enhancing production management in a thorough and practical manner, while promoting low-carbon, green practices to improve quality and efficiency.\" It will work to strengthen basic management to consolidate the foundations of production, and emphasize innovation and reform to boost productivity, thereby achieving a qualitative leap in production management! Safe production is a prerequisite for high productivity and low consumption. A new year, a new starting point! Enterprise safety in production is of utmost importance! Adhering to the principle that safe production must not be half-hearted, and driven by a strong passion for work, the Production Technology Department is committed to fully achieving the production targets for the Year of the Tiger! First, continue to promote the \"Guidelines for the Implementation of Process Safety Management in Chemical Enterprises,\" refine the control of production processes and the lean process indicator system, strengthen basic production management, and comprehensively improve the level of safety process management ； Second, strengthen risk management by inviting third parties to conduct HAZOP analyses on the system devices, and provide HAZOP training for the technical personnel working on these devices, in order to improve their ability to identify and mitigate risks ； Third, continuously strengthen internal training to improve the professional skills of staff, and enhance the ability of departments to assist production plants in solving problems. Scientific scheduling is the key to stable operation. A new year, new goals! Every scheduler in the Production Technology Department must maintain a vigilant attitude, keeping a close eye on key metrics without any slack or negligence ； Maintain a competitive and diligent work attitude, monitor carefully, address alarms promptly, and take decisive action for emergency response. First, continue to pay close attention to the hourly production rate without relaxation; conduct timely information comparisons, identify and analyze the underlying reasons, and adjust various process parameters as needed to ensure that the hourly production target is met, thereby achieving all set objectives and tasks ； Second, further advance \"tabletop exercises\" to enhance scientific scheduling and command capabilities as well as the emergency response skills of all staff, thereby reducing unplanned downtime ； Third, it is necessary to strengthen the timely handling of process alarms at various positions, to ensure that process parameters remain within acceptable limits and thus maintain stable operation of the production system. Unleashing potential to improve efficiency is the engine for enhancing energy efficiency. A new year, a new journey! Every specialist in the Production Technology Department must possess the determination to \"go into the den of the tiger to obtain its cubs,\" go straight to the front lines, understand the current situation, investigate thoroughly, explore ways to improve efficiency, and ensure the efficient and stable operation of the production system! First, carry out in-depth benchmarking management: benchmark against historical best practices to identify opportunities for cost reduction and profit improvement, and benchmark against industry leaders to strive for excellence and set examples ； Second, it is necessary to organize the comprehensive system maintenance work in April this year effectively, keep track of the projects aimed at improving the energy efficiency of ammonia synthesis, and ensure that these projects are integrated into the system as soon as possible so as to achieve the goal of producing 2,700 tons of ammonia per day ； Thirdly, close attention is paid to the production load of BDO; the feed rate for acetylation in Phase 1 is maintained at 9 m3/h, while that in Phase 2 remains at 19.5 t/h. Continued efforts are made to gain experience in controlling the content of hydroxybutanol, with the aim of extending the service life of the hydrogenation catalyst to 6 months ； Fourth, 17 energy-saving and emission-reduction technical improvement projects, such as the energy-saving renovation of the air separation circulating water system and the recovery of exhaust gas from the deaerator, were carried out to improve the energy efficiency of the production facilities.
