Introduction

Interpretation of GB/T 34236-2017, the National Standard of the People's Republic of China

Background and Significance of Standard Formulation

With the transformation of global energy structure and the improvement of environmental protection requirements, CO2-to-methanol technology, as a green chemical process, has important strategic significance. The formulation of GB/T 34236-2017 aims to standardize the design, construction and operation of CO2-to-methanol production equipment and promote the industrial application of this technology.

This standard is under the jurisdiction of the National Gas Standardization Technical Committee, combining the practical experience and technical development needs of the industry to ensure its scientificity and practicality.

Comparison of Standard Frameworks

Standard Dimensions	GB/T 34236—2017	International Benchmarking Level	Industry Status
Technical Requirements	Specify the raw material quality requirements, process design parameters and equipment material standards for carbon dioxide and hydrogen.	Align with international advanced standards and comply with the principle of sustainable development.	Promote the improvement of the technical level of domestic enterprises.
Environmental Protection Requirements	Emphasis on waste gas, waste liquid treatment and noise control to ensure compliance with GB 31571 and other standards.	International standards have stricter environmental protection requirements.	Domestic enterprises need to speed up technology upgrades to meet higher requirements.
Safety specifications	Require the design of the device to comply with HG 20571 and AQ/T 3034 to ensure safe production.	International standards focus on the establishment of a process safety management (PSM) system.	Domestic enterprises need to strengthen the construction of a safety culture.

Core processes and technical points

Process flow of carbon dioxide to methanol

The typical process flow of carbon dioxide to methanol includes:

Gas compression system: raw gas compressor and circulating compressor.
Synthesis reaction system: preheater, synthesis tower, water cooler, separator, water washing tower.
Distillation system: deetherification tower, pressure distillation tower, atmospheric distillation tower.

Among them, the technical requirements for synthetic methanol catalyst are shown in Table 2, including key indicators such as external dimensions, bulk density and radial compressive strength.

Implementation suggestions and future prospects

To ensure the efficient application of carbon dioxide to methanol technology, it is recommended that:

Strengthen equipment selection and material selection to ensure long-term reliable operation.
Optimize process parameter design to improve reaction efficiency and product quality.
Pay attention to environmental protection measures to ensure that waste gas and waste liquid treatment meet standard requirements.
Promote the application of pressure swing adsorption (PSA) technology to improve hydrogen utilization.

In the future, with technological progress and policy support, carbon dioxide to methanol is expected to become an important technical path to achieve carbon neutrality goals.
