Gas plant diversity united by economics, flexibility and proven design

J. Lewis, WorleyParsons, London, UK When examining technology options for new gas processing plants, it is important to consider how global gas plant diversity translates into design. It is also necessary to understand the available processing options and the complexity that is introduced by multiple-field processing. Gas processing considerations Prior to processing, natural gas comprises a mixture of components (Fig. 1). Processing adjusts the composition to allow for production of elements to saleable specifications, and this includes both impurities removal and hydrocarbon treatment. These two aspects (Fig. 2) are not independent, and an optimal process scheme will consider synergies
