A computer program to optimize the use of land and ensure safe operation of plant. A logical process flow is maintained, while the position of plant items is optimized using a hill-climbing technique.
A number of quantitative techniques exist for the measurement of hazard values for comparison of process routes in chemical plant design and operation. Such numerical values can also be used as a basis in lay-out considerations. There is a need for a simple technique, which allows for the optimization of separation distances between plant by determining the minimum requirement for safe operation. This requirement determines the cost of land and that of piping and control lines. It is then possible to carry out economic comparisons between using separation distances and the installation of mobile and fixed prevention and protection systems. An optimization technique based on a modified hill-climbing method is described.
