In this paper, a parallel double-effect or heat integrated organosilicon monomer distillation scheme is simulatively proposed with the aid of computer simulation to research the effect of heat integration on exergy loss of distillation process. The x–y diagrams of three groups of key...

In the present paper, a five-column heat integrated methanol distillation scheme is proposed with the aid of process simulation and pinch analysis. Unlike the popular four-column (or 3 + 1 column) scheme, a medium-pressure column is added after the light ends column in this novel scheme. The...

After a brief discussion of the motivations and criteria for making energy plans based on renewable sources, a number of renewable energy plans is reviewed. The way in which such plans are constructed is investigated and a critical appraisal of each plan is attempted. Finally, some remarks are...

Starting from explicit value preferences, an energy system compatible with an alternative American future is outlined, based on efficient use of energy and renewable energy sources. It is demonstrated that the U.S. may become self-sufficient before 2000 and use only renewable energy by 2030. A...
