Disproportionation and isomerization problems in the aromatic hydrocarbons workshop 1
Thread Content
How is the heating rate (from cold hydrogen circulation to hot hydrogen circulation) controlled during catalyst drying in the disproportionation and isomerization units of the aromatic hydrocarbons plant? ? Is there a specific heating rate? ? Additionally, for the domestic HLD-001 type disproportionation catalyst being used at present, is there a minimum feed requirement for the first oil feeding upon startup? ?
The outlet temperature of the heating furnace is to be controlled at 30 degrees per hour; regarding the feeding of the mixture, it is necessary to refer to the startup plan in the SCRIPT, as the requirements there are quite detailed.
The reactor heating rate is 15–30°C/h; the minimum feed load is 60%, with pure toluene being the preferred feedstock
