Great Plains Model Development: oxygen plant flowsheet. Final report. [ASPEN model of the Great Plains Gasification Plant]

Technical Report ·
OSTI ID:6336610
An ASPEN model has been developed of the Oxygen Plant, Section 3000, of the Great Plains Gasification Plant. The bases for this model are the process description given in Section 6.16 of the Great Plains Project Management Plan, Lummus Oxygen Plant Schematic Process Flow Diagram, Dwg. No. SK D-7102-IK-2, and US Patent 3,947,259. The ASPEN model that has been developed considers only the components oxygen, nitrogen, argon, carbon dioxide, and water. The simulation was split into two models: (1) the complete flowsheet including the cold box without spray drying; and (2) the front end with spray drying and no cold box. The models are primarily flowsheet simulations which will give the material and energy balances and the equipment duties for a given set of process conditions. The model is unable to predict changes in process conditions that would result from load changes on equipment of fixed sizes, such as a rating model would. The model can be used for simulating the steady-state operation of the plant at or near design conditions, or in designing other oxygen plants. Both steam and cooling water requirements are calculated as part of the simulation. Several major process assumptions had to be made in the development of the flowsheet model because of the limited process information available. Among the most significant assumptions were the number of theoretical stages and operating conditions for the low and high pressure towers, the expander inlet temperature, and the warm end temperature difference. A complete list of assumptions can be found in Table 2. 49 references.
