摘要： The present invention provides a method for operating dual controller which monitors the state of a dual controller to determine whether the dual controller is faulty and enables operation thereof with a controller in a normal state. An operation method of a dual controller according to the present invention dq-converts control command output values of first and second controllers to calculate rates of change in dq conversion values and dq-converts feedback input values, fed back to the first and second controllers, to calculate average rates of change in dq conversion values. When the average rates of change in the dq conversion values for the control command output values and the average rates of change in the dq conversion values for the feedback input values for the respective first and second controllers are identical, the corresponding controller is determined to be in a normal state, and to be in a faulty state otherwise. According to the results of the determination, the controller in the faulty state is set to a standby state and the controller in the normal state is set to an active state.

摘要： Provided is a method for the separation and purification of high-purity 2,6-dimethylnaphthalene from a reaction mixture of dimethylnaphthalenes by continuous crystallization. According to the method, shell-tubetype crystallization apparatuses are used to perform crystallization operations under a continuous flow of a reaction mixture of dimethylnaphthalenes, which is obtained from the synthesis of dimethylnaphthalenes using o-xylene and butadiene as starting materials. As a result, high-purity 2,6-dimethylnaphthalene is separated and purified in a high yield from the reaction mixture. In addition, the method is advantageous in terms of energy saving when compared to conventional separation methods and enables continuous separation and purification of 2,6-dimethylnaphthalene on an industrial scale. A system for implementing the method is further provided.
