Recently, the electricity consumption index of Yinglit Chemical Resin has been significantly reduced, among which the production line of the chlor-alkali operation department has reached 1.34 tons/ton, setting a new historical optimal value.
Based on the actual production and operation, the company formulated a work plan for the "Year of Quality Improvement and Efficiency Improvement in Production and Operation". Through process inspection, it found out various reasons that affected resin power consumption, and formulated rectification measures one by one to improve the operating efficiency of the dissolved acetylene recovery device., ensure that the acetylene recovery reaches the optimal value and minimize the acetylene dissolution loss. Strengthen the management of acetylene cleaning systems, eliminate the sulfur and phosphorus content of acetylene gas, and ensure system safety and long-term and efficient operation of vinyl chloride catalysts. The conversion efficiency is monitored in real time, and the low-mercury catalyst is overturned after running for a specified time to ensure efficient and stable operation of the low-mercury catalyst. The equipment operation status will be disclosed every day before shift, and production operation data will be recorded and analyzed in a timely manner to ensure safe and stable operation of production, improve the start-up rate of the device, and reduce acetylene gas losses in the production system caused by start-up and shutdown. Keep a close eye on the operating conditions of the polymerization kettle during feeding, ensure that the valve is opened and closed during the feeding process, and the pump is started normally to ensure accurate feeding of the polymerization kettle. During the discharge process, strengthen the roving inspection of the monomer recovery system and timely adjust the liquefaction vent pressure setting value to reduce monomer loss caused by inert gas venting. After a series of measures such as optimizing production indicators, strengthening process management and control, strengthening equipment maintenance and management, and promoting technical improvement, the resin power consumption index has been reduced.
Since the beginning of this year, the company has solidly promoted the "Standardization Promotion Year" activities, carried out in-depth job skills training, improved employees 'technical level, strictly implemented operating procedures, implemented on-site inspection standardization work requirements, and combined smart chemical and production safety management platforms to carry out production inspections. Inspection ensures that no key inspection points are missed, effectively ensures safe, efficient and smooth operation of production, and further promotes the creation of excellence and efficiency in production indicators.
