T/GPCIA 0010-2024 The Thermal Desorption Unit Energy Consumption Limit for Products of Propane Dehydrogenation Equipment

Scope

Scope: This document specifies the energy consumption limits for the unit product energy consumption of propane dehydrogenation units, including energy consumption limit grades, indicator requirements, statistical scope, calculation methods, and energy-saving management and measures. This document applies to the calculation and evaluation of the comprehensive energy consumption of units producing propylene products from propane as raw material in existing, new, and modified/expanded facilities. Main technical content: The energy consumption limit grades for unit products of propane dehydrogenation units are shown in Table 1. Table 1: Energy consumption limit grades for unit products of propane dehydrogenation units Process unit Indicator unit Energy consumption limit grade Level 1 Level 2 Level 3 Propane dehydrogenation unit kgoe/t ≤420 ≤450 ≤480 Existing propane dehydrogenation units should meet the Level 3 requirements in Table 1. New or modified/expanded propane dehydrogenation units should meet the Level 2 requirements in Table 1. Advanced values for the comprehensive energy consumption of unit products of propane dehydrogenation units should meet the Level 1 requirements in Table 1. 6.1 The total comprehensive energy consumption of propane dehydrogenation units includes various fuels (fuel oil, fuel gas, etc.), power (electricity, steam, etc.), and energy-consuming fluids (water, nitrogen, compressed air, etc.). 6.2 The energy consumption calculation boundary of propane dehydrogenation units includes reaction units, catalyst regeneration units, product separation units, etc. 6.3 Energy output to external systems should maintain consistent values in statistical calculations. Condensed steam that has not been utilized as energy output should not be included in energy output statistics. 6.4 Propylene production is calculated based on qualified products produced by propane dehydrogenation units that meet the requirements of G
