... of the inputs from permeate flare meter to Distributed Control System (DCS), it was initially hypothesized that standard density input assumptions of 0.714kg/Sm 3 is unrepresentative of the density values of the supposedly CO 2 rich permeate flare. This has caused a large overestimation of permeate flare...

Among these models, the Palmer-Mansoori model ( Palmer and Mansoori, 1998 ) and the Shi-Durucan model ( Shi and Durucan, 2004 ) are two popular choices used in reservoir simulation of gas migration. Two key geomechanical assumptions are used in the above models...
