The traditional simulation of energy systems has been performed on main frame computers or work stations. This is due to a large number of memory intensive subroutines for things such as property relations. These systems are generally geared towards large systems, such as power plants. Smaller scale industrial and commercial plants have been largely neglected due to the costs of both the hardware and the software development. The past decade has seen exponentiel growth in the power of personal computers and a real dollars decrease in their cost. Tasks traditionally relegated to larger systems, such as time intensive iterative calculati6ns, are now performed on personal computers. As emissions regulations grow tighter and higher energy costs loom, the need to simulate smaller energy systems will increase. The low cost of personal computers and their ever increasing power (memory, storage and processing speed) make them the ideal candidates for such simulations. This paper will examine the simulation of these systems using an Intel 80486DX2 based computer using MS DOS 6.0 (and above). Three approaches will be examined: the use of a commercial equation solver (which includes property relations), the use of a commercial chemical and energy simulation package and the development of custom software. Additionally, the programming of property and performance relations will be covered. Simulations discussed in this paper are for steady-state and quasi steady-state systems.
