T/CPCIF 0151-2021 The maximum energy consumption limit for producing synthetic gas from coal per unit product

Scope

Scope: This document specifies the requirements, statistical scope, and calculation methods for the energy consumption (hereinafter referred to as "energy consumption") limits of unit products of coal-based synthesis gas produced by fixed-bed gasification, fluidized-bed gasification, and entrained-flow gasification (dry pulverized coal gasification and water-coal slurry gasification) processes. This document applies to the energy consumption control of production devices that use fixed-bed gasification, fluidized-bed gasification, and entrained-flow gasification (dry pulverized coal gasification and water-coal slurry gasification) processes, with the effective components being carbon monoxide and hydrogen. Main technical content: 4.1 Energy consumption limits for unit products: - The energy consumption limits for unit products of coal-based synthesis gas production enterprises shall comply with the requirements of Table 1. - When using inferior coal such as anthracite with high ash content and low calorific value, low-volatile bituminous coal, and lignite with high moisture content and low calorific value, as well as high-sulfur coal as raw materials, the limits may be appropriately relaxed. Table 1: Energy consumption limits for unit products Process Type Unit Product Comprehensive Energy Consumption/[kgce/kNm3 (CO + H2)] Fixed Bed 730 Fluidized Bed 730 Entrained-Flow Bed 680 Dry Pulverized Coal Entrained-Flow Bed 670 4.2 Entry values for energy consumption of unit products of coal-based synthesis gas production enterprises: - The energy consumption entry values for unit products of coal-based synthesis gas production enterprises shall comply with the requirements of Table 2. - When using inferior coal such as anthracite with high ash content and low calorific value, low-volatile bituminous coal, and lignite with high moisture content and low calorific value, as well as high-sulfur coal as raw materials, the limits may be appropriately relax
