Process laboratory modules

CASPiE modules typically begin with 3 weeks of introductory laboratory activities followed by 3 1 weeks of student-designed research projects. The introductory laboratory activities teach the students the skills and content knowledge necessary to understand the module s research area. After completing the introductory activities, the students are prepared for the second stage of the module in which they participate in the research process. Each module has two simultaneous yet distinct goals teaching both chemical content and the research... 

A few experiments have been carried out in the laboratory scale with a one litre hydrolysis vessel, connected to a small impeller pump and a Sartorius laboratory module fitted with DDS GR6-P membranes (0.2 m ). However, the flow resistance in this module was too large, and it was soon concluded that a resonably constant flux was unattainable. Despite these difficulties, the qualitative behaviour of the reactor variables could be predicted from the model and verified experimentally. For example, with decreasing flux DH increased, but the rate of the base consumption decreased, while the protein concentration in the permeate remained quite stable as predicted. The hydrolysate was evaluated and found comparable in quality to ISSPH produced in the batch process. These results have encouraged us to continue the work in pilot plant with the DDS-35 module, where we can expect considerably more favourable flow conditions. The first experiments carried out so far indicate that a reasonable flux in the order of 50 1/m /h (approx. 1 1/m /min.) can be attained but that foaming problems necessitate the construction of pressurized air free reactor. Future studies will therefore be needed to produce a complete experimental verification of the derived model.

The modules are computer-based laboratory simulations with engaging activities that emphasize experimental design and visualization of structures and processes at the molecular level. The modules are designed to help students connect chemical principles from lecture with their practical applications in the lab. Every module has a built-in accountability feature that records section completion for use in setting grades and a workbook for students to record and interpret their work. 

The photovoltaics industry could expand rapidly if the efficiency of polycrystalline modules could be increased to 15 percent, if these modules could be built with assurance of reliability over a 10- to 20-year period, and if they could be manufactured for 100 or less per square meter. Solar energy research has been largely directed toward only one of these issues efficiency. All research aimed at reducing manufacturing costs has been done in industry and has been largely empirical. Almost no fundamental engineering research has been done on either the laboratory scale or the pilot plant scale for cost-effective processes for the production of photoconverters. 

In conclusion, we have developed an efficient asymmetric synthesis of the selective estrogen receptor modulator 1. This process was scaled up in the pilot plant for the early steps in the synthetic route and in kilo laboratory scale for the later steps and finally 4 kg of the final product was made. The key process development and project support milestones are summarized below ... 

The second module. Method, involves determining the level of verification and validation to which the user s methodology has been subjected. Verification is the general process used to decide whether a method in question is capable of producing accurate and reliable data. Validation is an experimental process involving external corroboration by other laboratories (internal or external) of methods or the use of reference materials to evaluate the suitability of methodology (1). A menu of choices includes (1) the method has only been verified, (2) the method has been both verified and validated, or (3) the method has been neither verified or validated. 

Pacific Northwest Laboratories developed the compact or modular processing unit concept in 1991. Westinghouse Hanford Company (WHC) performed a detailed feasibility study with further development in 1992. Individual modules are expected to be manufactured off-site by commercial vendors.
