Abstract: This paper mainly considers the overall structure of Riemann solution and the existence and convergence of shadow wave solutions of the ternary simplified chromatography equations. According to Riemann initial data, and Riemann problem is divided into six different cases, Riemann solutions for the ternary simplified chromatography equations are obtained. When -1-≤0≤p+, the existence and convergence of shadow wave solutions in the sense of Schwartz distributions are proved. Finally, numerical simulation is given.

Key words: chromatography equation, shadow wave, delta shock, Riemann problem
