A new computer-based training program for ALCAP oil treatment systems has been designed in a user-friendly way to help power station operatives understand the theory of ALCAP systems. The program runs on Windows 3.1 or Windows 95 and is stored on a CD-ROM using multimedia techniques including animations, short video sequences, sound and text. It covers five basic sections: the ALCAP separation system, ALCAP fuel oil, ALCAP for lube oil, monitoring and control. The user works interactively through a series of well illustrated questions with the answers adjusted to one?s knowledge level. The entire course takes about one day to complete, after which the user?s performance can be assessed.
