Abstract:
The rules and considerations governing site and plant layout of a chemical plant are briefly presented. The application of computer in this field is discussed and a number of available programs are assessed. The basic aim behind the thesis has been to present and to describe in detail the plant layout technique suggested by Gunn(2), that is the method of decomposing a chemical plant into plant modules. The vessel arrangement in a building or on a site is related to an objective function by introducing piping and building or site cost, and a method of direct search is used to find the vessel arrangement that minimises the objective function. An attempt is made to introduce new concepts into the method and a computer subroutine for an automatic setting of constraints on module positions has been written and is presented. By introducing piping modules (or pipe-tracks) the technique is extended to include optimal routing of the main pipes in the plant. A simple procedure for finding all the practical, feasible and shortest routes of other pipes in the plant is also presented. For this purpose a computer subroutine has been written which also generates clash messages if the pipes clash with the plant items or any other volumes in the plant in which pipe-routing is prohibited. The computer program for the layout of plant modules is described in detail. The computer program for the layout of plant and piping modules including the pipe-routing sub-routine is also described. The optimisation of a small suspension polymerisation plant, and a 30 T/day polyester polymer plant is set out and described as an illustration of the methods of calculation. A scale model for the polyester polymer plant has been constructed using the results of computation.
