Description

Iron and steel production enterprise carbon emission management method
Technical Field
The invention relates to a carbon emission management method for iron and steel manufacturing enterprises.
Background
The proportion of the total carbon emission of the steel industry to the total carbon emission of the whole country is about 15%, and the high proportion makes the steel industry become the department with the highest carbon emission ratio in the manufacturing industry. Therefore, the national level specially provides a 'method for accounting and reporting greenhouse gas emission and a guideline (trial) for Chinese iron and steel manufacturing enterprises' for the production of steel, and correspondingly sets up the national standard GB/T32151.5-2015 part 5 for accounting and reporting the greenhouse gas emission: iron and steel manufacturing enterprises for helping and guiding the iron and steel manufacturing enterprises to scientifically and reasonably develop carbon emission accounting and reporting activities in the production process. The method is very helpful and meaningful for accurately mastering the total carbon emission and the primary structure of each steel production enterprise and further summarizing and even mastering the corresponding conditions of the whole steel industry.
However, this results in macroscopic data on carbon emission levels and structure throughout the steel production enterprise. For a flow-type steel production process consisting of various complex machining conversion processes, macroscopic carbon emission data at an enterprise level cannot go deep downwards so as to reflect the carbon emission condition of each constituent sub-process, and therefore, the sub-processes cannot be sequenced according to macroscopic information of carbon emission, and therefore, targeted emission reduction measures and optimization activities are taken for important sub-processes of carbon emission. In addition, the main steel products of the steel production enterprises are usually not classified into one type, and the macroscopic carbon emission data of the enterprise level cannot be subdivided into a certain type of specific products, so that the carbon emission level of each main steel product and the carbon emission constitution of each production sub-process forming the production link of the type of the product cannot be known exactly.
