【 摘 要 】

The objectives of this task given in the test specification were to expand the waste feed evaporator OLI model by including all the major components of the evaporator off-gas treatment system. Also as part of this task, two test cases were developed that defined the baseline untreated waste feed composition, target organic components to be tracked, and the waste-to-recycle blend ratio. The goal of this task was to develop air emissions projections for two test cases using the expanded waste feed evaporator OLI model. The organic partitioning predictions and air emission projections are ultimately to be validated against experimental data obtained during pilot evaporator tests. The Environmental Simulation Program (ESP) software, licensed by OLI Systems, Inc., was used to build the current as well as earlier models for the FEP 7. The steady state simulation package performs vapor/liquid/solid equilibrium for electrochemical streams and processes. All vapor/liquid/solid equilibrium is determined by the OLI simulation engine. This task partially satisfied the test conditions and requirements described in the Research and Technology Plan (PL-W375-TE00007, Rev. 0) prepared by Bechtel National, Inc. (BNI). Specifically, BNI will use the information obtained during this task to support environmental regulatory permitting efforts for the waste feed evaporator and further to provide the operating data and correlations for the RPP-WTP flowsheet model.
