コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the calculation, assessment, and energy consumption control of new, existing, and expanded facilities producing methanol, ethylene glycol, and dimethyl ether. Specifically, it covers enterprises using coal, natural gas, or coke oven gas as raw materials for methanol; ethylene, synthesis gas, or coal for ethylene glycol; and methanol for dimethyl ether. It does not apply to construction-phase or residential energy use within the enterprise.

技術要求

The standard establishes a three-tier energy consumption limit system for the specified chemical products, where Tier 1 represents the highest efficiency (lowest consumption) and Tier 3 represents the mandatory baseline for existing facilities. For methanol, the limits are differentiated based on raw material types, including bituminous coal, anthracite, lignite, natural gas, and coke oven gas. The standard specifies distinct requirements for continuous pressurized gasification versus atmospheric intermittent fixed-bed gasification technologies. For ethylene glycol, the energy consumption limits are categorized by raw materials: ethylene, synthesis gas, and coal. Notably, the calculation for ethylene and synthesis gas routes excludes the energy content of the raw materials themselves. For dimethyl ether, the standard sets unified limits and explicitly includes the energy content of the raw material methanol in the total energy consumption calculation. New and expanded facilities must meet the stricter Tier 2 requirements, while existing facilities must comply with Tier 3 limits.

試験方法

The standard outlines specific statistical boundaries and calculation methodologies rather than traditional laboratory testing. It requires the conversion of all energy sources into standard coal equivalent (kgce) based on measured low calorific values, referencing methods from GB/T 213 and GB/T 11062. The calculation includes energy consumed by production, auxiliary, and附属 production systems, while deducting externally supplied recovered energy. Specific calculation formulas are provided for total comprehensive energy consumption and per-unit product consumption.

よくある質問

What products are regulated under GB 29436-2023?

GB 29436-2023 regulates the unit product energy consumption of methanol, ethylene glycol, and dimethyl ether. It applies to production facilities using various raw materials, including coal, natural gas, ethylene, synthesis gas, and coke oven gas.

Are there any updates from the previous version of GB 29436-2023?

Yes, this version consolidates and replaces several previous standards, including GB 29436.1-2012, GB 29436.2-2015, GB 29436.3-2015, GB 29436.4-2015, GB 31535-2015, and GB 32048-2015. Key updates include revised energy consumption limit values, the addition of energy consumption limits for coal-based ethylene glycol production, and updated statistical scopes and calculation methods.

How does GB 29436-2023 define the energy consumption limits for new versus existing facilities?

The standard uses a three-tier system. Existing facilities must comply with the Tier 3 limits, which serve as the mandatory baseline. New and expanded facilities must meet the more stringent Tier 2 limits as an access requirement. Tier 1 represents the most advanced and efficient energy consumption level.
