Energy process synthesis

ADVENT, developed by Union Carbide Corp., is capable of minimizing the energy and capital requirements of process synthesis.

R. Atkinson and F. Houtermans apply Gamow s theory of potential barrier penetration by quantum tunnelling to suggest how stars can release nuclear energy by synthesis of hydrogen into helium by an (unspecified) cyclic process. 

The energy released is captured in the form of a molecule known as adenosine triphosphate (ATP) and is used to drive all our energy-requiring processes synthesis of complex molecules, movement, nerve conduction, muscle contraction, and so on. 

This will be one of the processes shown, all of which have a large negative AG and are capable of harnessing this energy via synthesis of ATP molecules. However, even these are not achievable directly, and the electron transport chain of oxidative phosphorylation is utilized.

C(OCH3)R] (59) are certainly formed via the initial steps of the above reactions. Isomerization of 59 through pairwise formation of carbene bridges should be a low-energy process. Hence it appears that simple dinuclear metal carbonyls in general have all the prerequisites for yielding bis-/x-methylene complexes in the course of the Fischer procedure for metal carbene synthesis. 

Formally, the hierarchical design procedure can be divided in two steps process synthesis and process integration. The first deals with the synthesis of the process flowsheet and basic material balance. The second step handles the problem of efficient use of energy and helping material resources (water, solvents, hydrogen). Clearly, the two steps are interrelated. 

This case study deals with the design and simulation of a medium size plant of lOOkton cumene per year. The goal is performing the design by two essentially different methods. The first one is a classical approach, which handles the process synthesis and energy saving with distinct reaction and separation sections. In the second alternative a more innovative technology is applied based on reactive distillation.
