Abstract


With the tendency of crude oil getting heavier and poorer worldwide, the delayed coking process which becomes a well-developed heavy oil processing technology has drawn more and more attention recently owing to low equipment cost, simple process, operating flexibility and a high ratio of diesel oil to gasoline. In a delayed coking unit, the main fractionation column is the most important part for the products separating. The optimization and reform of the main fractionator has great practical significance.In this article, the structure of the main fractionation column was discussed. The strategy to simulate the fractionator segmentally was determined and the model was established. Then, the thermodynamics method and the number of the theoretical plate were chosen. The calculation results of the main fractionation column which were simulated by Aspen Plus and Pro/Ⅱsoftware respectively were consistent with the on-site operational data. It indicated that the calculation results by software was available and correct. The simulated results could be used for the the internal design of the main fractionation column.The bilayer fixed valve was studied in this article. The hydrodynamic performance of this plate was investigated with air-water system in a stainless steel column of 1200 mm internal diameter, and carried on the comparison with the F1 float valve, and the correlations of plate pressure drop,weeping and entrainment with weir height,liquid loading intensity and kinetic energy factor based on valve holes were obtained.It could be used conveniently in industrial applications.According to the existing problems of the main fractionation column of the delayed coking unit, the hydraulic calculation was made by using the simulated results. The problems which led to abnormal operation in the main fractionation column were found out. An economic and reasonable design scheme was put forward. The bilayer fixed valve was applied to the reforming design successfully.
