HOW IS THE PROCESS BROUGHT INTO BETTER CONTROL?
The design intention is to equip the plant, as necessary, with state-of-the-art analysers, in order to obtain accurate and timely measurement of key process data. The equipment list includes Gas Composition and Melt Flow Index analysers. The object is to progressively upgrade the control system of the polymerisation process. The most cost effective way for all concerned is to work in a two-sided consultative manner. At the outset project objective and delivery are to be agreed along with the targets of budget, time scale and benefit.
The project is to be carried out in three stages:
Stage 1 – closed loop control – for mid-campaign periods of steady running
Stage 2 – transition control – for grade changes
Stage 3 – process optimisation – progressive refinement of the new control system
