Small-medium scale polygeneration systems: Methanol and power production

摘要: Abstract The feasibility and attractiveness of the integrated production chemicals electrical power is dependent upon on nature products their demands. This study focuses small-to-medium scale combined methanol (200,000 tonnes/year) (200 MW). system considers both recycle (recycle ratio = 5) once-through (no recycle) modes synthesis. results simulations show that, when compared to separate stand-alone plants for production, systems lower consumption total fresh synthesis gas operation 2.8% 3.7%, respectively. In addition, that advantage over increases further in face decreasing catalyst activity or selectivity, rising 10% several scenarios. because off-spec material from an plant can be diverted generation section plant. These savings operating costs are above substantial capital cost which realized design a
