PROJECT OVERVIEW

The main focus of this project is to find the expected steam economy of the Engelhard Evaporator Sets. This will be accomplished in a step-by-step process. Starting with finding the heat and material balances, heat transfer coefficients and finding thermocompressor flow as function of motive steam. This project was assigned on the 6th of September 2001, with the first company visit occurring on October 6th, 2001.

This report describes the design process that was followed through the fall and spring semester. A user friendly interactive excel spreadsheet has been designed to track changes in steam economy, when the vapor thermocompression inputs of motive and load steam pressure change. Steam economy is defined as the total steam evaporated per total steam used. The users can then analyze how the changes in the input pressure affect the steam economy, and can then determine proper pressures to run the evaporator system in order to obtain optimal steam economy.
