Abstract: The refining industry is a traditional energy and emissions intensive industry.The low-carbon development of refining industry is of great significance for energy-saving and emission reduction in China.An intra-enterprise carbon flow analysis model is established based on material flow analysis (MFA) method.Taking a 10 million t/a refinery in China as an example,the carbon flow rule and the hidden carbon emissions for the refinery in 2015 are analyzed and calculated respectively.Furthermore,the trends of CO2 emissions reduction in this refinery during the period of 2016-2035 are predicted under three scenarios.It is found that 82 kg of hidden carbon emissions will be generated when one ton of crude oil is processed.Secondary processing section is the largest part of the hidden carbon emissions,accounting for about 75.1% of the total emissions.Among them,the delayed coking unit is the main process for implying carbon emissions,accounting for about 42.8% of the total hidden carbon emissions.Compared with levels in 2015,the hidden carbon emissions by 2035 can be reduces by 11.7%,14.9% and 19.6%,respectively under these three scenarios.
