Chemical companies are big consumers of energy, and energy conservation has also become the focus of most chemical companies. But when it comes to energy conservation, many companies think of "hard" content such as going on projects, carrying out technological transformations, and changing raw material routes. On the eve of the National Day, the reporter learned that when interviewing several chemical companies that performed energy-saving work better, there was also a huge potential for energy savings in terms of management, management, and other “soft†content.
Li Fa, chairman of Shandong Shouguang Xinlong Electrochemical Group, told reporters that enterprises must establish a comprehensive system of statistics, testing, evaluation, and evaluation in order to save energy. At present, many chemical companies do not attach importance to this. In recent years, Xinlong Dianhua Group has established a team energy auditing system for major equipment and workshops, and conducted energy monitoring and statistical analysis every day and every class to implement assessment indicators for key raw materials and equipment energy consumption. Personally, we have established a complete set of monitoring mechanisms for the whole process of energy use. Make energy consumption no longer eat a big pot of rice, the energy consumption status of each post, everyone knows. For example, the boiler saves coal from coal purchase, coal blending, combustion to slagging, and the production of calcium carbide from purchase to product is included in the integrated monitoring and evaluation. It is understood that this system makes Xinlong company's calcium carbide per ton more than five manufacturers than the same amount of gas, only the first half of this year the company's energy consumption per million yuan in value than the same period last year fell 0.18 tons of standard coal. Li Fa has said that it seems that this amount is not large, but this is the effect of relying on a set of management system without increasing investment.
Cao Guang'an, deputy general manager of Jiangsu Hengsheng Chemical Fertilizer Co., Ltd., also believes that only by establishing a sound assessment system can each worker have the pressure to save energy and reduce consumption, so as to gradually eliminate heat, materials, running, running, dripping and leaking. He said that originally, their cost assessment standards were reported by the production department of the company and were formulated by the management department, so that the production department was bound to leave a margin of its own. Now they are instead set up by the management department and put electricity, steam, coal and auxiliary materials at the same time. The assessment of consumption was refined, and the main energy-consuming equipment and sections were evaluated separately. This not only enhances employees' awareness of energy conservation, but also leaves no room for the department.
Wang Zuping, vice general manager of Jiangsu Jiada Chemical Co., Ltd. believes that overall planning, careful planning, rational arrangement, and optimization of production operations can reduce unreasonable energy use and energy consumption in the production process, thereby achieving the purpose of energy conservation. The company timely adjusted the number of machines running at each pumping station of the power utility project based on changes in the seasonal climate. At the same time, steam pipe network optimization is carried out to reduce steam energy levels and optimize the matching relationship between fans and compressors and other equipment and pumps. These management innovations have reduced the power consumption of the company's power utility and the steam consumption of the production system year by year. When they inspected the 10-kiloton boiler induced draft fan of 75 kilowatts, they discovered that the motor rated at 140 amps only required 80 amps during normal operation and there was a phenomenon of “big horse-drawn carsâ€. They immediately switched to a 45 kilowatt motor. For this small optimization, a single motor can save more than 10 million yuan a year.
Water supply systems in oil and chemical production companies are marginal industries and have always been a weak link in management. If you strengthen the management of the water supply system, you can save a lot of water energy. The management of circulating cooling water in chemical companies has the concept of “three-point pharmaceuticals and seven-point managementâ€. For example, the general chemical fertilizer companies account for 80% of the total water used for circulating cooling water, and the amount of circulating water for a set of 180,000 tons of synthetic ammonia and 300,000 tons of urea is 20,000 cubic meters per hour. Reducing the water consumption of circulating cooling water is the key to reducing the total water consumption of a company's production. Therefore, strict and detailed management is very important.
Sinopec Zhenhai Refining & Chemical Branch has accumulated rich experience in water saving and emission reduction management in recent years. Chang Xucai, head of water treatment at the company's mobile division, said that natural water consumption should not be less than 20% for production water drawn from the surface or underground to enter the production system. In order to reduce the loss of this part, the company has taken four measures. The first is to establish a water quality indicator control day analysis ledger and process technology ledger, establish a material leakage ledger, keep abreast of the trend of water quality changes, eliminate the defects of water quality management; second is to strengthen the tracking management of key links in order to check in a shorter time Leaking point of Ming material to avoid deterioration of water quality and large amounts of replenishment and other issues; third is to strengthen the stability of water system operation management, formulate a strict water quality assessment system, so that the qualified rate of water quality indicators is controlled over 95%; fourth is to strengthen system operation innovation Management, for some devices there is intermittent operation, when the device is short-term outage, the use of water-cooled equipment cut out of the circulating water system in a timely manner, and optimize the system operating mode, reduce the amount of circulating water, thereby reducing the amount of additional water consumption and energy consumption. The improvement of these several management measures saved a lot of water resources. The company’s water recycling rate reached more than 98%, and tons of crude oil consumption fell from 0.97 tons to 0.42 tons, and entered the international advanced level.
According to the national plan, during the “Eleventh Five-Year Plan†period, the energy consumption of China’s unit GDP should be reduced by 20%, and energy conservation is an important way to achieve this goal. "Management of energy conservation" is one of the first choices for energy conservation. Therefore, for oil and chemical companies that are at the forefront of energy conservation, don’t just focus on technology and investment, or try to dig and manage this energy-saving “gold mineâ€.
