Verification of a system assembled and operated on orbit requires unique testing technologies and places a premium on advanced simulation and analysis... 

To facilitate the use of methanol synthesis in examples, the UCKRON and VEKRON test problems (Berty et al 1989, Arva and Szeifert 1989) will be applied. In the development of the test problem, methanol synthesis served as an example. The physical properties, thermodynamic conditions, technology and average rate of reaction were taken from the literature of methanol synthesis. For the kinetics, however, an artificial mechanism was created that had a known and rigorous mathematical solution. It was fundamentally important to create a fixed basis of comparison with various approximate mathematical models for kinetics. These were derived by simulated experiments from the test problems with added random error. See Appendix A and B, Berty et al, 1989. 

The most commonly used philosophy is to design a test facility that simulates the relevant process stress. Examples of such test facilities are the various jet attrition test devices which are used in fluidization technology. 

A proposal for the comprehensive study of chemical processes in a variety of important condensed-phase systems using modern theoretical methodology has been presented. The primary goals of the research are to provide microscopic information on the mechanisms and structural and dynamical properties of the chemical systems proposed for investigation, to test the applicability of modern ab initio molecular dynamics (MD) by comparison with experiment, and to develop and apply novel ab initio MD techniques in simulating complex chemical systems. The proposed research will contribute to the forefront of modern theoretical chemistry and address a number of important technological issues. The PI has carefully attempted to demonstrate his knowledge, ability, and resources to carry out the proposed research projects. 

IGT has developed a treatability protocol for the MGP-REM technology to determine cleanup rates and the preferred mode of treatment (landfarming, soil slurry, or in situ). The protocol consists of three phases Phase I is a feasibility test comparing a variety of techniques and is completed within 2 to 3 months phase II is a bench-scale optimization under simulated field conditions and phase III is the field-scale evaluation. 

Startech PWC systems are applicable to manufacturing facilities, hospitals, process plants, military sites, and municipalities. Systems have been used in the field to treat chemical weapon and explosive simulants. In addition, the vendor claims that the technology has successfully treated metals, such as lead and barium, during testing. The technology is commercially available in the United States and overseas.
