Modelling emissions from natural gas flaring - …

The annual gas flaring emissions from annual gas flared in billion cubic metres (bcm) for CO 2, CO, NO, NO 2 and SO 2 are given in Tables 4. For validity, the predicted output for CO 2 is compared with annual world estimates as shown in Tables 4 and Fig. 1. The trend for this study shows that for an increasing gas flared volume, there is a
