Distributing Characteristics within Fuel Cell Stacks with features that Fuel/Air Manifolds Penetrated through Plane Zone and Open Outlet Manifold
Dai Fen Chen
September 19, 2018 (v1)
Keywords: 3D large scale simulating, Flow and temperature distribution characteristics, Solid oxide fuel cell stack, Structure features
Although many numerical models based on different fuel cell stack designs have been developed in past decades, most of the achieved optimized results are greatly dependent on the specific designs, cell numbers and geometric values. Achieving the general relationship between the structure features and distribution trends of key physics items, that is independent on the specific design would be high instructive. To achieve high volumetric/gravimetric power density and simple manufacturing process, both fuel and air manifolds of a solid oxide fuel cell (SOFC) stack are always designed to place within cell plane zone and penetrated through it; and open outlet manifold is also adopted. In this study, the three dimension large scale multi-physics numerical model for a typical SOFC stack with the above two design features is well completed by carefully coupling momentum, mass, energy and quasi electrochemical reaction equations. Then, the general relations between these structure features and... [more]
Aspen Plus Simulation of Biomass-Gas-and-Nuclear-To-Liquids (BGNTL) Processes (Using CuCl Route)
James Alexander Scott, Thomas Alan Adams II
August 7, 2018 (v1)
These are Aspen Plus simulation files for a Biomass-Gas-and-Nuclear-To-Liquids chemical plant (a conceptional design), which uses the Copper-Chloride route for hydrogen production. This is a part of a larger work (see linked LAPSE record for pre-print and associated publication in Canadian J Chem Eng). Process sections and major units in this simulation include: Gasification, Integrated-Gasification-Methane-Reforming, Pre-Reforming, Water Gas Shift, Autothermal Reforming, Syngas Blending and Upgrading, Solid Oxide Fuel Cell power islands, Fischer-Tropsch Synthesis, Methanol Synthesis, Dimethyl Ether Synthesis, Heat Recovery and Steam Generation, CO2 Compression for Sequestration, Cooling Towers, and various auxiliary units for heat and pressure management. See the linked work for a detailed description of the model.
Petroleum coke and Natural gas-To-Liquids Aspen Plus Simulation
Ikenna J Okeke, Thomas A Adams II
July 19, 2018 (v1)
Keywords: Aspen Plus, Fischer-Tropsch Synthesis, Integrated Reforming, Petroleum Coke
Six Aspen Plus simulation files for the conversion of petroleum coke and/or natural gas to liquid fuels (synthetic gasoline and diesel) are presented. The base simulation files were designed with carbon capture and sequestration (CCS) technology with the corresponding plant without CCS.

The processes may include various technologies such as petcoke gasification, integrated gasification and autothermal natural gas reforming, gas cleaning, water gas shift reaction, MDEA based carbon capture, Claus process, FT synthesis, and other processing steps.

The six processes are: PSG_CCS (petcoke standalone gasification with CCS), PSG_No_CCS (petcoke standalone gasification without CCS), PG-INGR_CCS (petcoke gasification integrated natural gas reformer with CCS), PG-INGR_No_CCS (petcoke gasification integrated natural gas reformer without CCS), PG-ENGR_CCS (petcoke gasification external natural gas reformer with CCS), PG-ENGR_No_CCS (petcoke gasification external natural gas reformer with...

Biomass-Gas-and-Nuclear-To-Liquids Aspen Plus Simulations
Leila Hoseinzade, Thomas A. Adams II
June 12, 2018 (v1)
Aspen Plus simulation for eight different chemical processes. Each simulation corresponds to a process which convert biomass, natural gas, and in some cases, nuclear energy, into either dimethyl ether (DME) or Fischer-Tropsch liquids (synthetic gasoline and diesel). Some processes contain carbon capture and sequestration (CCS) steps.

The processes may include various technologies such as biomass gasification, steam methane reforming, integrated gasification and natural gas reforming, integrated high temperature gas-cooled reactors and natural gas reforming, water gas shift reaction, FT synthesis, DME synthesis, MEA or MDEA based carbon capture, gas combustion turbines, gas cleaning, and other processing steps. Nuclear energy, when used, is integrated into the system via a high temperature helium coolant as an energy carrier from certain kinds of Gen IV nuclear reactors.

The eight processes are: BGNTL-FT (biomass-gas-nuclear-to-liquids with FT synthesis), BGNTL-FT-CCS (the same w... [more]
