Improving Efficiency in HuaYu Energy Chemical’s Gasification Workshop Author/Source: HuaYu Energy Chemical Shanxi Co., Ltd. Date: May 17, 2022 Views: 11 Since HuaYu Energy Chemical adopted the \"Three Precision Management\" approach, its gasification workshop took immediate action to implement precise management strategies aimed at improving efficiency and reducing costs, thereby achieving the goal of enhancing quality and productivity. Every effort is made to ensure the stable operation of production. Stable production is a fundamental prerequisite for a company’s profitability. This workshop, after clarifying the responsibilities of its employees, further details their tasks, bringing management to every individual position. By considering factors such as processes, equipment, and safety, it strengthens the control over various process parameters as well as the maintenance of equipment. It also pays special attention to the management of backup units for key equipment such as coal mills and feed pumps in washing towers, promptly identifying and addressing any potential issues, thereby ensuring the stable operation of the four furnaces under high loads over extended periods of time. Strict control over various types of consumption – precise management is the core element of the \"Three Precisions Management\" approach. This workshop maintains strict control over various consumables such as coal, electricity, water, steam, chemicals, and spare parts, and it continuously optimizes relevant metrics while carrying out meticulous operations, thereby providing strong support for achieving production goals that involve cost reduction and increased efficiency. By regularly evaluating the operating efficiency of the coal grinding machine, increasing the proportion of coal particles with a size of 90μm or less, and continuously optimizing the operating parameters of the gasification furnace based on the quality of the coal and the conditions of the furnace, it is possible to improve the carbon conversion rate as well as the concentration of useful components in the syngas ； At the same time, by improving the precision of equipment operation management, strict control is exercised over electrical equipment to reduce its idling rate and save energy consumption ； Precise control of the water system to avoid unnecessary addition of fresh water, desalinated water, etc ； In areas of equipment where high heating requirements are not necessary, the heating system should be turned off appropriately depending on the season and temperature changes, and any leaks in the steam system should be addressed promptly ； A daily inventory check system is implemented for the use of chemicals, with adjustments made based on various analytical indicators to prevent waste ； Continue to implement the system of repairing and reusing old items to increase the utilization rate of used spare parts. Continuously advancing technological innovation, gasification, with the production of syngas as its main objective, holds many potential advantages that can be exploited. For example, coal slurry and coarse slag can still be recycled, as well as water, steam, etc. Under the company’s leadership, the gasification plant continues to pursue technological innovation and engages in close cooperation with various industries and sectors outside the company, thereby increasing the added value of its gasification facilities. For the innovative projects that have been put into operation, joint management and optimization are carried out with the relevant workshops to ensure the continuous and stable operation of projects such as the comprehensive utilization of coal slime and the washing and recycling of coarse slag. Actively cooperate with projects such as the low-pressure flash steam waste heat power generation project that are under development, continuously overcome technical challenges, and push forward with the implementation of these projects in order to strive toward achieving the company’s annual production targets.
