How can chemical companies save costs?
The core path for chemical enterprises to save costs is “technology upgrading+fine management+full staff participation”. Through systematic measures such as optimizing procurement, energy conservation and consumption reduction, equipment renovation and recycling, annual production costs can be reduced by 5% -8%. Based on industry practice, the following are key strategies that can be implemented:
1、 Source control: optimizing procurement and raw material management
Centralized procurement and long-term cooperation
Strive for price discounts through large-scale procurement and sign long-term agreements with high-quality suppliers to lock in prices, ensure supply stability, and reduce market volatility risks.
Diversified supply channels
Avoid relying on a single supplier, establish alternative mechanisms, enhance bargaining power, and prevent risks of supply interruption and price increases.
Research on raw material substitution
Explore alternative materials with similar performance but lower cost to achieve cost reduction while ensuring product quality.
2、 Energy conservation and consumption reduction: Technological innovation drives energy efficiency improvement
Process optimization and combined utilization of heat
Adjust reaction parameters (such as temperature, pressure, reflux ratio) to increase conversion rate and reduce energy consumption.
Promote thermal integration between devices to achieve heat transfer from high-temperature logistics to low-temperature logistics, maximizing energy cascade utilization.
Equipment upgrade and frequency conversion transformation
Adopting efficient heat exchangers, air coolers, compressors and other energy-saving equipment to improve the energy efficiency of individual equipment.
Implement variable frequency speed regulation for the motor, dynamically adjust the power according to the load, and avoid the phenomenon of “big horse pulling small car”.
Induction heating replaces traditional heating methods
If a certain chemical enterprise changes the heating of a 100kW reaction kettle from thermal oil to induction heating, it can save an annual electricity fee of 312000 yuan, recoup costs in 14 months, and increase the thermal efficiency to over 95%.
Waste heat recovery and resource recycling
Install heat pipe exchangers and waste heat boilers to recover heat from high-temperature exhaust gas and waste liquid for preheating raw materials or generating electricity.
Implement technologies such as dry quenching and closed coke removal to improve energy efficiency and environmental protection level.
3、 Refined Management: Extracting Benefits from Daily Operations
Dynamic energy monitoring
Establish an energy consumption monitoring system to track real-time electricity, gas, and water consumption, identify waste points, and promptly rectify them. Jilin Petrochemical once recovered its investment cost within three months after repairing the damaged insulation of the steam pipeline.
Optimization of inventory and material direct supply
Reduce the use of intermediate tanks, promote direct supply of benzene and other materials, and reduce nitrogen consumption and volatilization losses.
Implement precise inventory management to avoid backlog and expiration, reduce capital occupation and loss.
Repairing and reusing old and waste materials, as well as recycling and reusing them
The first chemical department has saved nearly 200000 yuan in coal costs annually by recycling and reusing waste coal slurry from gasification equipment.
Promote “repairing old and utilizing waste”, repair high-value spare parts such as seals for large machinery pumps and reciprocating air valves, and reduce procurement expenses.
