networks to remove carbon dioxide from natural gas feed with high heavy hydrocarbon
content. Single stage separators were added to facilitate the initial removal
of heavy hydrocarbons and carbon dioxide. Three different case studies along
with the conventional cryogenic network have been investigated. Thermodynamic
behavior of CH4-CO2 mixture was analyzed to synthesize
appropriate network configuration at higher pressures. The effect of number
of separators, their positions and operating conditions on energy requirement,
methane recovery and final purity of methane was studied. A considerable reduction
in energy has been reported for case studies 1, 2 and 3 over case study 0 (conventional
distillation network). Indicative profit index was formulated and calculated
for the each case study.]]>Atkinson, T.D., J.T. Lavin and D.T. Linnett,19881988Basak, K., K.S. Abhilash, S. Ganguly and D.N. Saraf,20024115571568Berstad, D., P. Neksa and R.
