How can chemical industry companies improve productivity?
The core of improving productivity in chemical industry companies lies in systematically eliminating production bottlenecks and achieving safe, efficient, and green continuous operation through technological innovation, process optimization, and intelligent management. Based on industry practices and technological trends, the following is a multidimensional improvement path from process, equipment, management to collaboration:
1? Technological Innovation: Driving Efficiency Leap with Advanced Processes and Catalysts
Technological breakthroughs are the fundamental driving force for improving productivity, especially in terms of reaction rate, selectivity, and energy consumption control.
Developing efficient catalysts
Highly selective catalysts can significantly improve the yield of target products, reduce the generation of by-products, and lower the difficulty and energy consumption of separation and purification. For example, the new molecular sieve catalyst achieves over 95% selectivity in olefin polymerization, significantly shortening the process chain.
Adopting mild reaction conditions
Promoting low-temperature and low-pressure catalytic technology to replace traditional high-temperature and high-pressure processes can not only reduce energy consumption, but also minimize equipment losses and safety hazards. If a new type of supported catalyst is used in the hydrogenation reaction, the conversion can be completed at 80 ? and 2MPa, with a 40% reduction in energy consumption.
Introducing Continuous Flow Microreaction Technology
Compared to traditional batch reactors, microreactors have stronger heat and mass transfer capabilities, enabling second level mixing and precise temperature control, improving reaction efficiency by more than three times, while reducing equipment volume by 60%.
2? Device Intelligence: Building Automation and Real time Monitoring Systems
The automation control system reduces human intervention and ensures continuous and stable production, which is the key to improving operational efficiency.
Deploy DCS/PLC automatic control system
Realize closed-loop control of parameters such as temperature, pressure, and flow rate to avoid parking or inefficient operation caused by operational fluctuations. A certain chlor alkali enterprise has improved its equipment operation rate by 8 percentage points through DCS transformation.
Establish a real-time data monitoring and warning platform
Utilizing IoT sensors to collect key equipment status and process parameters, combined with AI algorithms to predict abnormal trends, and intervening in advance to avoid unplanned downtime. The Total Productive Maintenance (TPM) mode can effectively eliminate efficiency losses caused by sudden failures.
Promote the application of digital twins
Build a virtual factory model, simulate the operating effects under different working conditions, optimize equipment layout and operation plans, reduce resource waste and debugging time.
3? Process optimization: eliminate waste and create a lean production system
Lean management focuses on identifying and eliminating various "hidden wastes" in production, unleashing the potential of the system.
Optimize material flow path
Repositioning equipment according to the process sequence to avoid repeated handling of raw materials and semi-finished products between workshops. The compact production line design can shorten transportation distance by more than 50% and save production time.
Promote the single piece flow production mode
Transforming "batch production, queuing and waiting" into "one flow" continuous operation, reducing work in progress backlog and inventory occupation, and maintaining smooth production line flow.
Reduce production preparation time
Analyze internal and external operations using the SMED (rapid mold change) method to minimize equipment switching time. For example, a certain fine chemical plant reduced batch switching time from 2 hours to 30 minutes, resulting in a 15% increase in daily production capacity
