The invention provides a process for eliminating hydrogenation process coking materials and deposits and a design method thereof. A removal agent is used for dredging on easy coking and depositing positions, and is prepared from additives and 250 to 520 DEG C distillate oil generated in the hydrogenation process; the additives are prepared from one or several kinds of materials from benzene sulfonate or naphthenate accounting for 0.1 to 0.7 weight percent of the total mass of the removal agents, one or several kinds of materials in amino amino trimethylene phosphonic acid, diethylenetriamine pentamethylphosphonic acid, edetic acid and HEDP accounting for 0.1 to 0.5 weight percent. A viscosity and pressure difference detection instrument is arranged in the easy coking and depositing positions for monitoring the viscosity and pressure difference change in real time; when the viscosity is higher than 750cSt or the pressure difference is higher than or equal to 100KPa, the dredge speed is10 to 15m / s, and the dredge temperature is higher than or equal to 200 DEG C; when the viscosity is higher than 250cSt but lower than or equal to 750cSt, or the pressure different is higher than 40KPabut lower than 100KPa, the dredge speed is 5 to 10m / s.
