Under the same production equipment and technology conditions, the internal influencing factors of efficiency are actually reflected in various consumptions, especially energy consumption. Jiangmen Electrochemical Plant is a key energy-consuming unit with an annual standard coal consumption of n tons. In 2004, 2005, and the first half of 2006, the total energy consumption was 110,848.01 tons of standard coal, 113,360.06 tons of standard coal, and 54,448.4 tons of standard coal, respectively, accounting for 39.48%, 34.49%, and 36.60% of the total product cost. Due to the large proportion of energy consumption in the cost, Jiangmen Electrochemical Plant has long been actively carrying out activities to address energy conservation and consumption reduction in order to improve the company's efficiency. 1. Adopting new technologies to reduce energy consumption 1.1 Liquid plate packaging In 2005, the liquid chlorine submersible pump packaging process was adopted to replace the traditional vaporization packaging process. After passing acceptance testing and being put into operation in March 2006, the refrigeration process could reduce the operation of one 195kW ammonia compressor, while the liquid chlorine submersible pump motor power was only 45kW, resulting in annual electricity savings of 1.26 million kWh. At a rate of 0.55 yuan/(kW·h), this translates to electricity cost savings of 693,000 yuan. The project involved a total investment of 750,000 yuan, and the investment cost could be recovered in 13 months. 1.2 Installing frequency converters on high-power motors: Since 1994, frequency converters have been installed on all pumps and motors with a power of 30kW or higher throughout the plant, reducing pump power consumption by more than 20%. This now saves 1.092 million kWh of electricity annually, resulting in electricity cost savings of 600,600 yuan. The project involved a total investment of 650,000 yuan, and the investment cost could be recovered in 13 months due to electricity savings. 1.3 Adoption of Energy-Saving Air Compressors Starting in 2005, screw air compressors replaced piston-type oil-free air compressors, reducing the air station load from 124kW to 92kW, saving 310,800 kWh of electricity annually and saving 171,000 yuan in electricity costs. Furthermore, the new machines have fewer malfunctions, saving up to 100,000 yuan in maintenance costs annually. The project investment of 260,000 yuan can be recovered within one year. 2. Electrode Recoating and Repair to Reduce Electrolysis Power Consumption 2.1 Recoating 30-1 Metal Anodes By 2003, the 03-1 metal anode electrolytic cells had been in operation for over 10 years, and the anode coating began to peel and fail, causing a rapid increase in cell voltage and power consumption. From February 2004 to February 2006, a total of 1.5 million yuan was invested in recoating 54 30-m diaphragm iron anodes. After recoating, the AC power consumption decreased from 2490 kWh/t to 2430 kWh/t, saving 1.8 million kWh annually and 90,000 yuan in electricity costs. The recoating cost can be recovered in 18 months. 2.2 Recoating the Anode and Cathode of F: Electrolyte As of June 2003, the F: ion-exchange membrane electrolyzer had been in operation for 9 years, far exceeding its 6-year service life, and the active coatings on some of the anodes and cathodes had peeled off and failed. The peeling and failure of the active coating will cause the cell voltage to rise rapidly, resulting in increased power consumption. From December 2003 to the present, a total of 2.9 million yuan has been invested in recoating and activating the electrodes of 16 electrolyzers with a capacity of 20,000 t/a ion-exchange membranes, reducing the AC power consumption of 1 ton of caustic soda from 2360 kWh to 2196 kWh, saving 3.28 million kWh annually and 1.804 million yuan in electricity costs. The recoating cost can be recovered in 19 months. 3. Reducing Energy Consumption Through Technological Upgrading 3.1 Adopting a Mixed Caustic Soda Process to Reduce Coal Consumption Starting in January 2003, Jiangmen Electrochemical Plant implemented a mixed caustic soda process, using a mixture of 32% ion-exchange membrane caustic soda and 29% diaphragm caustic soda to produce a 30% finished caustic soda product. This significantly reduced the steam consumption from direct evaporation of the electrolyte into the 30% diaphragm finished caustic soda product. In 2005, the comprehensive steam consumption per ton of caustic soda was 124 kg, a decrease of 524 kg/(t·NaOH) compared to 2648 kg per ton in 2002. Based on an annual production of 7500 ton of caustic soda, this saved 39300 ton of steam, 4598 ton of standard coal, and 1.93 million yuan in costs annually. 3.2 Shortening Filtration Time to Save Electricity Through improvements to the chloroacetic acid production process, the filtration time during production was shortened, achieving the goal of saving electricity. Since July 2004, through reasonable scheduling, the average filtration time for each batch of chloroacetic acid has been shortened. Based on an annual production of 400 tons, with 10 batches per month, approximately 211,200 kWh of electricity can be saved annually, resulting in electricity cost savings of 116,000 yuan. 3.3 Ammonia compressor series refrigeration saves energy. Since April 2004, single-stage refrigeration compressors and double-stage refrigeration high-pressure compressors have been operated in series, making reasonable use of the compressor's refrigeration power. Even with one less ammonia compressor, normal chloroacetic acid production can be guaranteed. Through series operation, 980,000 kWh of electricity can be saved annually, resulting in electricity cost savings of 539,000 yuan. 3.4 Indirect cooling replaces direct cooling, reducing production costs. The original AC foaming agent oxidation process used an ice-making machine to take tube ice, which was then manually added to the reaction vessel to directly cool the reaction liquid and control the reaction temperature. This method resulted in high energy consumption, high labor intensity, low production capacity, and the hard ice blocks easily damaged the rubber lining of the oxidation vessel (especially the agitator). After the technological upgrade, chilled brine is used for indirect cooling of the AC oxidation reaction solution. Under the same production capacity, only two reactors are needed instead of the original three, significantly reducing energy consumption. This saves approximately 830,000 kWh of electricity annually, resulting in electricity cost savings of 456,500 yuan. Simultaneously, it significantly reduces labor intensity, eliminating the need for 8 operators in the oxidation process and reducing labor costs by over tens of thousands of yuan annually. 4. Conclusion Through various energy-saving and consumption-reducing activities, substantial expenses are saved annually, production costs are reduced, and the ability to withstand market risks is enhanced.
