One or more base functions may be generated and blended with existing program code, such that it may be difficult or impossible for a potential attacker to distinguish the base functions from the existing code. As well, with the pervasiveness of powerful communication networks, the ease with which computer software programs and data files may be accessed, exchanged, copied and distributed is also growing daily. In order to take advantage of these computer and communication systems and the efficiencies that they offer, there is a need for a method of storing and exchanging computer software and data securely.

This was the first project that the students saw in the new curricu- lum. Since they had no chemical engineering background at that stage, the project was very simply stated and all engineering jargon had to be explained.

They were given the process flowsheet de- picted in Figure 1, and the functions of all blocks representing pieces of equipment were carefully explained.

Written descriptions of the process chemistry and the process itself were provided. The flow rates of most of the streams were provided, and the primary project goal was to work backwards to determine the conver- sions of the ethanol to the desired product acetaldehydee and to the by-products acetic acid, ethyl acetate.

Although the process itself did feature a recycle stream, by giving the flow rates for it the material balances reduced to those for an acyclic process. As the project teams considered this task over two weeks, they received more formal instruction on units, analysis and measurement, non-reactive material balances, material balances on multi-unit systems, stoichiometry, reactive material bal- ances, and combustion.

The material was quite structured to respond directly to what they needed to complete the assign- ment-they were not expected to "dig it out" for themselves at this stage.

The project introduced them to a variety of chemical engineering terms, allowed them to see the work they were doing in the context of a complete, although much simplified, process, and helped to motivate the study of the introductory material.

S Level 2, Project 3 The students were at a quite different stage at the start of this project, almost exactly halfway through the year. They had covered material and energy balances, 1s" and 2"d law thermodynamics, and could design and analyze flashes and staged distillation columns as well as power and refrigera- tion cycles.

They had seen recycle on a small scale, for 7 individual equipment and power cycles, but had not yet attacked a complete flowsheet with recycle.

They were still using ideal-gas concepts or steam tables for properties, and Raoult's law for phase equilibria.

The function of this project was to introduce the students to a moderately complex recycle process, as shown in Fig- ure 2. The process included recycle of unconverted reac- tants, purge, and make-up streams, and recycle of absorber cooling water.

The process was gas-phase, running at bar, except for the absorber 40 bar and distillation column 1 bar. This high-pressure process motivated the introduc- tion of real gas behavior, although as the gases were mostly hydrogen and nitrogen, the actual deviations were not large. In addition to performing a complete material balance, the students were asked to design several aspects of the equipment.

They were asked to evaluate the possibility of replacing the expansion valve, VAL-1, by a turbine to recover useful work, and to determine the cooling duty required for the cooler, CLR-2, in that case. They had performed such calculations before in the ideal-gas case, but were now instructed to use the Lee-Kesler generalized correlations to calculate residual properties.

The presence of the absorber moti- vated introduction of some lecture material on the design of this equipment, which provided an opportunity to revisit the operating- line concepts seen before in distillation design and to contrast the use of Henry's law for gas-liquid equilibria with that of Raoult's law for vapor-liquid equilibria.

Their last task was a design of the distillation column and the refrigeration cycle used to condense the ammonia in the overhead, which again forced them to re-use prior Figure 2.Systems and techniques for securing accessible computer-executable program code and systems are provided.
