Continuous Flow Measurement of Coal Liquids Physical Properties: The Chemical Engineering Technician's Role.

摘要

A small-scale, continuous-flow, coal hydroliquefaction system is being operated at Oak Ridge National Laboratory (ORNL) to determine the physical properties (e.g., viscosity, density, thermal conductivity, and heat capacity) of coal liquids under process conditions. These data are essential for proper design of equipment for large scale coal liquefaction processes. This paper describes lead technician responsibilities for the design, construction, and operation of the facility. There are many challenges to the technician in this research area: data analysis and interpretation, process modifications and additions, craftwork supervision, troubleshooting, and operational decisions during experiments. Examples are given showing how a technician's associate degree education provided excellent preparation for the challenges encountered during this project. (ERA citation 06:003313)
