Hubei's Chemical Enterprises Make Electric Multiplication Benefit

According to the Hubei Provincial Electric Power Company's dispatching and communications center, this year's power shortage in the province is a foregone conclusion, and the peak of electricity consumption is more than a month earlier than in previous years. It is estimated that this summer, the shortage of electricity will be 1.8 billion kwh, and the shortage of electricity will be 3.8 billion kilowatts. At that time, the tension situation of power supply and demand in summer peak power will be unprecedented.

Some key chemical companies in Hubei made early preparations to make reasonable use of electricity, increase capacity positively, and strive to grasp the initiative of using electricity to ensure that many parties benefit.

Hubei Jianghan Oilfield Salt Chemical Plant, located in Qianjiang City, actively supplies electricity for oil and gas production and residential life, and the main equipment is frequently under load-reducing operation. At present, during the golden season of product sales, the cadres and workers of the plant do not complain, do not give up, tap the potential inwards, and strive to minimize the production losses caused by the power shortage.

“We have carefully adjusted the production and operation methods, implemented the production and operation plans for 'peaks, flats, and valleys.' In the valley section, we use more low-priced electricity online to generate less electricity; in the flat section and peak section, we use less electricity online to generate more electricity. The peak and valley electricity device operation program, we will take the tons of alkaline electricity consumption as an important task for the employees to 'learn to help and surpass the subject' activities, guide employees to calculate the cost account, and do a good job of the economic operation of the device.” Jianghan Oilfield Salt Chemical Plant Xie Hui, deputy director of the party committee's working department, told reporters.

The plant's production and organization department has intensified the fine management, worked out the “peak, flat, and valley” three-hour production and operation plans, discharged the large-scale operating tables, and compiled the operating essentials and emergency plans for three periods of lifting and lowering currents. The current of the device is reduced to the lowest level, and the daily process rectification and minor inspections are concentrated in the time period during the day; after entering the night, the current of the device is gradually increased, and the zero-hour period is put into full production.

According to Xie Hui, the plant also used the opportunity of the first phase of the Sichuan-East Gas Storage and Storage Project to invest in more than 40 million yuan to build a 110-kilovolt transformer substation and supporting line project, which effectively improved the safety and load regulation of the power grid. ability. With the commissioning of the 110 kV line, the newly added power supply capacity will be 31.5 megawatts. After the capacity expansion, the long-term power supply capacity will reach 126 megawatts, and the electricity consumption is no fault.

Double Star Dongfeng Tire Co., Ltd. is a large consumer of electricity in Shiyan City. They increased low-voltage power supply facilities and purchased 8 low-voltage cabinets this year. In May, the low-voltage power distribution cabinets of logistics transformers were reconstructed; Increased power failure emergency lighting facilities, in the event of a sudden power outage, is conducive to the emergency evacuation of workshop staff.

Hubei Qianjiang Jinhua Run Chemical Fertilizer Co., Ltd. has an annual production capacity of 200,000 tons of synthetic ammonia, 200,000 tons of urea, 100,000 tons of ammonium bicarbonate, 400,000 tons of compound fertilizer, 60,000 tons of methanol, and 150,000 tons of dimethyl ether. The company currently has two 110-kilovolt substations, of which one has an installed capacity of 31,500 kVA for the production of electricity for the old system. In 2010, the electricity consumption was 209 million kilowatt-hours. The one installed capacity that has just been put into use is 110,000 kVA for the production of electricity in the new system. In January of this year, the power sector limited the company's power supply for half a month, and the pressure limit load was all around 14,000 megawatts. Enterprises could not produce at all. "In order to ensure safety in production, we have repeatedly explained to the power sector that production of chemical fertilizers has high temperature, high pressure, high continuous, flammable, explosive, and easily poisoned production characteristics, and that we did not pull the brakes," said Liu Qianbo, an office worker of the company.

Sun Bing, an office secretary of Hubei Sanonda Co., Ltd., said that they are doing everything possible to save energy consumption to reduce production costs. Strengthen benchmarking and energy conservation management by enhancing electricity-saving awareness. Since the end of last year, the company has enhanced material and energy balances for its main products, compared the theoretical consumption to identify gaps in raw materials and energy consumption, adopted corresponding technological reform measures, and reduced raw materials and energy consumption. By enhancing the daily maintenance of the company's substations, it will increase the compensation for power grids. In addition, they also changed the operating mode of the glyphosate motor so that the running current of each motor decreased.

Hubei Yihua Group, Sinopec Hubei Chemical Fertilizer, Wuhan Gehua Group, Hubei Xinyangfeng Co., Ltd., Hubei Hubei Chemical Industry Co., Ltd. and Hubei Saning Chemical Company all have their own power plants or generator sets, even if they are Electricity is also not affected. It not only satisfies the production of electricity, but also sells surplus electricity to the Internet.

Guo Songshan, deputy general manager of Hubei Dagukou Chemical Co., Ltd., told the reporter that Dagukou Chemicals is a large power consumer in Jingmen City. Even though the electricity during the Spring Festival is also very tight, the local government has special protection, and the power supply department has given priority. At present, they continue to strengthen internal management, tap potential, do a good job of energy-saving emission reduction, to minimize consumption. At the same time, it will make overall plans for the rational use of hydropower peaks and scientific arrangements for power dispatch so that efficient product installations can be fully opened.
