Description
Summary:Using the energy approach formulated earlier by the authors, a mathematical model was constructed, which in turn is the basis of the calculation method for predicting the residual life time of the rectification column for production of ethylene under the wind load and atmospheric corrosion. It should be noted that wind load is shunting in nature with constant pressure on the column and frequent gusts. There is an external surface corrosion-mechanical crack in the circular weld, by which the column is attached to the base. The corrosive environment penetrates into this crack. Such a corrosive environment together with the shunting wind load intensifies crack propagation to the size, which causes failure of the column. Using the energy approach, this problem is reduced to special differential equations with special delta functions, which are solved approximately for a large number of wind gusts. Using the energy approach the dependence of the 09G2C steel column residual life time on the number of wind gusts, was investigated.
