Refining system for aromatic solvent oil

摘要

a refinement system for aromatic solvent oil, characterized by the system being a semi -liquid storage tank for aromatic solvent oil,includes a crystallisation device and a finished product storage tank which are interconnected,where the aromatic solvent oil storage tank and the crystallisation device are connected by a line,and where the system continues to include a pre -cooling system consisting of a pre -cooling vessel running from top to bottom and cooling circuit water,which the pre -cooling container is filled with includes, and where the line is partially in the pre -cooling device,and where the part of the line contained in the pre -cooling system has a transient modal distribution; and where the crystallisation device has a crystallisation container,a cooling source located on the top of the crystallisation vessel, a filter seed located on the bottom of the crystallisation vessel and a filter seed placed on the crystallisation vessel,includes a thermometer used to measure the internal temperature,and where both ends of the filter screen are separately connected to an inner wall of two opposite sides of the crystallisation container,and with the middle section of the filter screen facing upwards and the finished product storage tank connected to the bottom of the crystallisation container,and where two opposite sides of the crystallisation vessel each have a naphthalene crystal outlet,and where the naphthalene crystal outlet is above a connecting point between the filter seed and the crystallisation vessel.
