Title:
CONTINUOUS DRY PETROLEUM REFINING APPARATUS
Document Type and Number:
Japanese Patent JPS6060189
Kind Code:
A
Abstract:

PURPOSE: To remove colored materials with simple equipment in a simple manner, by treating a colored material-contg. oil with an acid, removing pitch formed, applying voltage to the residual acid radical to ionize it and adsorbing it by a polar adsorbent.

CONSTITUTION: Oil sucked through a sucking pipe 1 is heated, for example, to 40°C by a first heater 5, fed to a line mixer 6 and treated with an acid from an acid reservoir 8, and pitch formed by the acid treatment is separated by a centrifugal separator 10. Voltage is applied to the residual acid radical in the oil by an electrode device 12 to ionize it, the oil is heated to 80W90°C by a second heater 13 and the ionized acid radical is adsorbed by a polar adsorbent within first and second adsorption towers 14, 15. After the ionized acid radical is adsorbed, the oil is filtered by a filter 16 to remove the polar adsorbent, whereby the removal stage of colored materials such as gum, tar and sulfur compds. in the oil is completed. After the oil is passed through the filter 16, the acid in the oil is detected by an acid-detecting device 17. If the oil is unacceptable, the operation is stopped. Flow rate is detected by a flowmeter 14 so as to keep the mixing ratio of the oil and the acid constant.
