《GB 31830-2024甲苯二异氰酸酯和二苯基甲烷二异氰酸酯单位产品能源消耗限额》由469（国家标准化管理委员会）归口，委托TC20（全国能源基础与管理标准化技术委员会）执行。
Introduction
1. Background of standard formulation and technical evolution
The formulation of GB31830-2024 aims to further regulate the unit product energy consumption limit of toluene diisocyanate (TDI) and diphenylmethane diisocyanate (MDI) and improve the energy efficiency of industrial production. Compared with the old standards (GB31828-2015 and GB31830-2015), the new standard has significant improvements in scope of application, energy consumption level classification and technical requirements.
2. Comparison of standard frameworks
| Standard dimensions | Old version requirements (GB31828-2015 and GB31830-2015) | New version requirements (GB31830-2024) |
|---|---|---|
| Scope of application | Only covers the energy consumption limit of a single product | Integrates the general standard of two types of isocyanate products |
| Energy consumption level classification | No clear classification indicators | Newly added three-level energy consumption limit (Level 1 is the best) |
| Statistical scope | Covering production systems and auxiliary systems | Explicitly exclude domestic energy consumption and optimize data calculation boundaries |
3. Interpretation of the core content of the standard
3.1 Energy consumption limit level
The energy consumption level of TDI and MDI products is divided into three levels, with the specific indicators as follows:
| Product type | Level 1 (optimal) | Level 2 | Level 3 |
|---|---|---|---|
| TDI | ≤340 kgce/t | ≤500 kgce/t | ≤950 kgce/t |
| MDI | ≤175 kgce/t | ≤180 kgce/t | ≤190 kgce/t |
3.2 Technical requirements
Existing production enterprises:Must meet the requirements of Level 3 indicators; New or expanded projects:Must meet the access standards of Level 2.
4. Implementation suggestions
4.1 Energy consumption monitoring and accounting
- Establish a complete energy measurement system to ensure the accuracy and completeness of the data.
- Refer to the calorific value conversion coefficients in Appendix A and B to standardize the statistical method of energy consumption.
4.2 Energy efficiency improvement measures
- Optimize production process and reduce energy waste.
- Promote waste heat recovery technology and improve energy efficiency.
- Strengthen equipment maintenance and update to reduce system energy consumption.
