The computer optimization control system for the catalytic cracking unit of gasoline quality

In the process of refining petroleum, the gasoline-final boiling point and the steam pressure 10% point, which are major indicators of gasoline quality, can not be real time measured online. Therefore, controlling gasoline quality has become a major difficulty in the field of industrial processing control. This paper introduces the designing thoughts and the realization method of computer optimization control for gasoline quality. By means of soft-meter [1] monitoring and optimizing techniques, along with setting up the dynamic mathematics model of gasoline-final boiling point online, the complicated technologies of computer monitoring and optimal controlling of gasoline quality for the catalytic cracking unit can be carried out.
