"Chemical Enterprise Energy Auditing Standard" will be implemented on October 1

On July 19th, the reporter learned from the China Chemical Industry Energy Technology Association that the “Energy Auditing Standards for Chemical Companies” and “Petrochemical Energy Auditing Standards” drafted by the China Chemical Industry Energy Technology Association were recently issued by the Ministry of Industry and Information Technology. It was formally implemented on October 1, 2011. This is the first standard specification issued for energy audit work in the nine high energy-consuming industrial industries.

It is understood that the two energy audit standards stipulate the definitions, contents, methods, procedures, and report preparation requirements of chemical audits for petrochemical and petrochemical enterprises, and are applicable to petrochemical and chemical production enterprises and other independently accounted petrochemical and chemical products. Production unit.

According to the reporter’s understanding, the National Development and Reform Commission and other departments organized “thousand companies” to carry out energy audits in 2006. Subsequently, provinces, cities, and central enterprises also organized energy audits for key energy-using units. As the energy consumed by chemical and petrochemical enterprises not only serves as fuel, power, but also part of energy or production raw materials, the production process and equipment of chemical and petrochemical enterprises also have their own particularities. Therefore, entrusted by the National Development and Reform Commission and the Ministry of Industry and Information Technology, China The Chemical Industry Energy Technology Association drafted two industry standards, "Environmental Auditing Standards for Chemical Enterprises" and "Environmental Auditing Standards for Petrochemical Enterprises", to help energy auditors better understand the energy utilization status of petrochemical and chemical companies, and proposed practical and feasible Energy-saving measures recommended.

According to Wang Wentang, the chief drafter of the standard and the Secretary-General of the China Chemical Industry Energy Technology Association, the energy auditing standards for chemical and petrochemical enterprises are based on the general principles of energy auditing technology for enterprises, highlighting the combination of energy use characteristics of chemical and petrochemical companies for energy audits.

The standard requires auditing the energy use of the enterprise from three aspects: the process system, the thermal system, and the electrical system. The energy utilization efficiency of chemical production equipment is greatly influenced by the inherent characteristics of the system. For example, the energy consumption of the process system is mainly affected by various parameters determined by the production process. Generally, it cannot be changed. Considering energy conservation from the technological point of view, priority should be given to whether the process route can be changed. Whether there is a process route with lower energy consumption; and then, under the premise of satisfying the requirements of the process parameters, how to reasonably use energy, including the chemical energy released by the process, in order to achieve the purpose of energy saving. The analysis of energy utilization of thermal systems and electrical systems also needs to consider the requirements of the production process.

The standard requires a detailed audit of the use of raw materials and energy. Energy as a raw material for production is one of the most obvious features of energy use in the chemical industry. Different from the supply of energy, to produce a certain amount of chemical products, unless the production process is fundamentally changed, the production of raw materials is generally difficult to reduce, that is to say, as the energy of raw materials, the possibility of reducing the use of energy is very small . “What we can do, if we have the potential for energy saving, is to reduce energy that is used as fuel and power.” Wang Wentang explained that energy audits clearly distinguish energy consumption from raw materials, and then clarify the consumption status of burning energy. Finding suitable energy-saving measures also facilitates energy management departments at all levels to accurately understand the energy use of chemical companies.

The standard also puts forward detailed requirements for the calculation of the company's energy costs. Because of the high proportion of energy costs in production of high-consumption products, some even reach over 70%. Through the calculation and analysis of energy costs, it can help enterprises to further recognize the importance of energy conservation in improving the economic efficiency of enterprises.

It is understood that the national and provincial energy conservation authorities are organizing the audit of the energy use of key energy-using units during the “11th Five-Year Plan” period, and the issuance of these two standards is just at the right time. “The implementation of the energy auditing regulations for chemical and petrochemical enterprises will fundamentally reverse the situation in which energy audits go through the motion, put forward clear requirements for the depth of energy audits for chemical and petrochemical enterprises, and require that energy auditors must have high business performance. Level. Through in-depth analysis of the state of energy use of enterprises, help to fully tap the potential of energy saving companies, put forward more energy-saving measures, and then improve the energy efficiency of the entire industry." Wang Wentang said.
