The control-detection design to temperature, pressure and flux for the process which consists of a fractionation tower, a steam tower, a segregator, a oil amortized tower and a catalytic cracking refining pot was made based on the “Chemical automatic design rules”. After a simple introduction for the flowsheet, some suitable meters and valves were choose. And the interrelated blueprint about the automation design, technics flowsheet chart and the loop hookup were drawed.
