How does the chemical industry save energy and reduce consumption?

Energy saving and emission reduction is a basic national policy of our country, but also the inevitable choice to achieve sustainable economic development of our country, as a large energy consuming chemical production industry, should pay more attention to this issue. Energy conservation and consumption reduction is to take technically feasible and economically reasonable measures to improve the efficiency of energy utilization and minimize energy consumption. At present, the energy-saving measures taken in the chemical industry mainly include the following aspects:

1, the use of new technology and new equipment advanced production technology and energy-saving equipment is an important means for chemical enterprises to save energy and reduce consumption. The use of advanced technology to optimize the total energy consumption of the process, including the use of energy-saving flow, optimization of process parameters (such as conversion, reflux ratio, cycle ratio, etc.), improve the operating flexibility of the device, improve the reaction operating conditions, reduce energy consumption. Energy-saving equipment such as mass transfer, heat transfer and rotation, such as high-efficiency fractionator, heat exchanger, air cooler, pump, compressor, heating furnace, etc. are used, and the production capacity of single equipment is improved to achieve energy saving and consumption reduction from the source.

2, reduce power energy consumption Power energy consumption mainly includes power and steam consumption, is the main part of chemical enterprises energy consumption. Reducing power consumption can use motor frequency conversion speed regulation technology. Based on the current situation of low load rate of most chemical enterprises, adopting variable frequency speed regulation technology is undoubtedly an effective way to save energy. Heating system optimization. It is reasonable to implement the combination of devices, optimize the matching of cold and hot logistics in a large range, and realize the optimization of energy utilization.

3, comprehensive utilization of energy chemical enterprises use a variety of energy, the grade varies, the process has both heat absorption and heat release, the production of a large number of fuel, steam, electricity, mechanical energy and the production process produced in the combustible gas, reaction heat and a variety of residual energy effectively combined, in order to obtain the efficient use of system energy. About 80% of the total heat energy consumed by chemical enterprises is eventually released as low heat energy. Therefore, the effective utilization of low heat energy is the key to improve the utilization rate of chemical energy.

4, descaling and anti-corrosion insulation chemical enterprises, continuous operation of the heat exchanger is easy to appear scaling phenomenon, resulting in reduced heat exchange efficiency. It needs to be removed by chemical cleaning or mechanical cleaning, and it is a simple and easy way to use anti-scale agents to prevent or slow down scaling.

5, strengthen energy management In the field of chemical production by strengthening energy management, the use of source Rui energy consumption monitoring system, can reduce production energy consumption by 5% ~ 20%

Chemical industry is an important basis for industrial development, the importance of the chemical industry in economic life is self-evident, its downstream related to people's clothing, food, housing, clothing, construction, transportation, food and so on are inseparable from chemical products. However, in the face of many problems such as high energy prices, low market demand and unstable supply chain, the market demand has gradually weakened, and the demand for cost reduction and efficiency increase of chemical enterprises has become increasingly urgent. 

From the perspective of cost reduction and efficiency improvement and practical application, the digitalization of supply chain procurement will become the best focus and entry point for chemical enterprises to accelerate digital transformation and upgrading. Because the procurement scale of chemical enterprises is large, the total cost is relatively high, and the price of raw materials fluctuates greatly under the influence of the market; The industry is more and more segmented, and the whole chain collaboration between upstream and downstream is more and more important; At the same time, the chemical industry's original supply chain information system also has a huge space for upgrading.
