Study evaluates the impact of nitrogen on gas processing efficiency

Instituto Mexicano del Petróleo conducted a study to evaluate the effects of high nitrogen levels on gas processing operations. The results show that the diethanolamine (DEA) solvent does not absorb nitrogen and, for the same gas and solvent flow rates at different compositions, the sweetening process does not appear to be affected.Because some of the natural gas streams from wells in the Cantarell reservoir, Gulf of Mexico, began to contain more nitrogen, we were interested in estimating its effect on gas processing operations, especially the sweetening and liquid recovery units. We therefore simulated the operations of these units at different levels of feed nitrogen.To simulate th...
