Conversion of glucose to hydrogen gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Glucose was gasified in supercritical water within a microchannel reactor at 650°C 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...

Development and dynamic analysis of an experimental heat integrated distillation column

Creator:: Golike, Gregory Philip
Abstract:: Heat integrated distillation has been studied using an experimental column built for that purpose. Heat integration involves the use of intermediate reboilers and condensers to increase the thermal efficiency of distillation. The intermediate reboiler and condenser systems used in this work were designed so that the experimental column could be...

Use of orthogonal collocation in the dynamic simulation of staged separation processes

Creator:: Matandos, Marcio
Abstract:: Two basic approaches to reduce computational requirements for solving distillation problems have been studied: simplifications of the model based on physical approximations and order reduction techniques based on numerical approximations. Several problems have been studied using full and reduced-order techniques along with the following distillation models: Constant Molar Overflow, Constant...

The plume model for large utility scale atmospheric fluidized bed combustors

Creator:: Park, Dalkeun
Abstract:: The atmospheric fluidized bed combustor (AFBC) is an alternative to the pulverized coal burner. The size of a utility scale AFBC would be enormous so that the use of large particles is necessary to reduce its size. In modeling the combustion of coal and capture of sulfur released from the...

Dynamics and control of a heat integrated distillation column with side heat exchanges

Creator:: Patil, Sadanand R.
Abstract:: One of the alternative energy-saving methods in a conventional distillation process is the use of side (intermediate) reboiler and/or condenser for a portion of the overall heat load. A nonlinear differential equations model was developed to describe the dynamics of a typical binary distillation process with and without the side...

Strategies for process flowsheeting

Creator:: Sanz, Carlos C.
Abstract:: Two packages of subroutines were developed to perform material balances on chemical processes using the simultaneous modular approach and the equation-based approach. The performances of these packages were compared for five different processes under at least two conditions: one with no design specifications, and one with two or more design...
