Zhenyang Development: Highlight three main lines to create energy -effective benchmarks

Following the title of "Standard Enterprise Benching Enterprise of the Energy Effective Leaders" last year, the China Petroleum and Chemical Industry Federation held recently at the Petroleum and Chemical Industry Energy Leaders Conference and Energy -saving and Carbon Technology Exchange Technology Exchange and Promotion Conference. Zhejiang Town Yang Development Co., Ltd. (hereinafter referred to as Zhenyang Development) has once again won the honor with a comprehensive energy consumption of alkaline -roasted units of 288.9 kilograms of standard coal/ton.

"The comprehensive energy consumption of Zhenyang Development of Alkali -Alkaline Unit has decreased from 302 kilograms of standard coal/ton at the beginning of '13th Five -Year Plan' to 288.9 kg standard coal/ton, a decrease of 4.34%, a decrease of 0.52%compared to 2020. This result is. Thanks to the firm grasp of Zhenyang Development's three main lines of energy saving, fine management, and production adjustment in recent years, "Wang Shiliang, chairman of Zhenyang Development, said.

Main line one:

Technological innovation deep digging internal potential

In recent years, Zhenyang Development has taken energy conservation technology transformation and technological innovation as the starting point, focusing on internal energy conservation and consumption reduction and potential, and achieved good results.

"Taking 2021 as an example. We have implemented more than 10 technical reform projects such as the intelligent improvement and transformation of chlor -alkali device and 32%bases, saline systems and hydrogen chlorine energy saving of enterprises in the park, and continued to improve the energy efficiency of the unit and achieve the use of waste heat. The annual festival can be about 16,500 tons of standard coal, "said Shen Shuguang, deputy general manager of Zhenyang Development.

The proportion of the power consumption of salt chemical enterprises has always been high in total cost, and the development of Zhenyang is no exception. At present, Zhenyang's energy structure is relatively single. The main energy is electricity and steam, of which electricity accounts for more than 90%of the total energy consumption. The electrolytic groove is the core equipment of the chloro -alkali system to develop chloro -alkali system. Earlier, the company used ion membrane electrolytic methods to produce products such as alkali and chlorine gas, but with the increase of the usage of the anode net and ion membrane, the anode net coating decreased year by year. , Increased production costs and higher voltage of the slot, cannot meet the requirements of full load operations.

In this regard, Zhenyang Development actively transformed the electrolytic groove. The second phase A/B grocery in March 2022 by using a high -current density naturally circulates the compound pole distance electrolytic slot, the equipment operation indicators reach the world's advanced world advanced The level has greatly reduced production energy consumption, saving electricity costs of more than 10 million yuan each year.

Main line 2:

Fine management reduces the energy consumption of the device

"48%alkaline steam consumption is high. We need to analyze the reason why the significantly increased month -on -month and calculate the economy of 48%alkali maintenance and the low -load operation of the low -voltage steam." On August 17, in the monthly economic analysis of the monthly economic analysis At the meeting, Ren Cohen, the person in charge of Zhenyang's development process, pointed out the problem of high energy consumption and then proposed a solution. This is one of the important measures for the active implementation of energy conservation requirements in Zhenyang.

In recent years, Zhenyang has developed a large -scale implementation of organizations to reshape, established a flat organizational organization, and promoted the functions of various departments to further accurate the functions of each department, further prominent subject responsibility, and further improved the level of professional management. At the end of 2021, the company completed the second round of organizational reform. After the reform, the production system established a monthly economic analysis mechanism, comprehensively analyzed and evaluated major economic indicators and issues such as the consumption of raw accessories, energy consumption. Corresponding rectification measures will continue to reduce energy consumption. In the first eight months of this year, the company's wax fuel consumption, epoxy oxide hydrogen chloride consumption, and epoxyopropane steam consumption decreased by more than 17%year -on -year.

In addition, the development of Zhenyang also strictly implemented the system of "Energy Conservation and Eatsurding Management" and "Energy Measurement Management", incorporated energy conservation and consumption reduction into the annual key work, clarified the work responsibilities of various departments, and signed the target book of energy conservation and emission reduction responsibility with various departments. Layer decomposition and implement the task of energy conservation and emission reduction; actively strengthen the operation of the energy management system, and use digital dynamic dynamic dynamic energy consumption strength, total amount, and energy consumption of various process units of the device, promote the energy diagnosis of various units of the enterprise, refine the quality of salt water, implement the implementation Energy management best and feasible technology.

Main line three:

Production adjustment and development clean energy

"In the past, the hydrogen of our by -labor was not asks, but now it has become 'Xiangxiang'." For the future market prospects of hydrogen, Li Zhi, the head of Zhenyang Development Marketing Department, is very optimistic.

Hydrogen energy is an important part of the national energy system in the future. The hydrogen produced by Zhenyang Development in the process of producing alkali and chlorine products. Due to the low purity, complicated composition, and technical means before, it was only used to produce steam in hydrogen -burning boilers. The use value and utilization rate were low. Essence After the company's demand for high -purity hydrogen in the park, the company immediately adjusted production, refined hydrogen, improved the quality of hydrogen, and was quickly favored by high -end customers in the park.

Zhenyang Development also improves technical means such as catalyst performance and changing recycling procedures. While greatly improving the capacity of existing device, the second set of hydrogen refined devices and a hydrogen transportation pipeline with independent property rights will be added to further meet the customer's pair of customers in the park. The demand for high -quality hydrogen is expected to supply more than 80 million cubic meters of hydrogen in 2022. At present, the company is taking an opportunity for the construction of a new material project of 300,000 tons of ethylene. After the project is put into production, the proportion of natural gas in enterprises can be increased from 0.15%to nearly 10%.
