Operational Flexibility Analysis of Chemical Plants
Abstract:Detailed research has been done on theory of feasibility analysis if Chemical plant in this paper，The methyl alcohol rectify tower which chooses unit and some low temperature methyl alcohol of the rectify tower operation and washes device is experiment research object, pass adopt the top method obtain and equip flexible operation coefficient, carrying on carrying out chemical engineering device of flexible analysis. which specifies the necessity and universal method of feasibility analysis Main content of the paper is as follows.
（1）Necessity of feasibility analysis of chemical plant has been specified. Comparison of different methods of resolution of the feasibility coefficients has been conducted， thus establishing the mathematics model with the index method.
（2）As an example， the feasibility of a methanol rectification tower in rectisol process and simple operation units has been analyzed and worked out with index method， as well as the feasible variation range of some uncertain parameters has been determined.
（3）The feasibility of Chemical plant is determined and the bottlenecks are found out based on the results of feasibility analysis， therefore the theoretical basis for retrofit of a plant is provided.
Get to draw a conclusion through this research: Set up the methyl alcohol rectify tower, adopted a top method to compute should equip of flexible analysis result, it can for should equip of expanding and producing the reformation provide to draw lessons from a function.
