Document Type and Number:
WIPO Patent Application WO/2020/059109
Kind Code:
A1
Abstract:
This operating method for operating a device for distilling crude oil to produce a plurality of distillates is provided with: a design step for estimating the amount of water contained in the crude oil or the flow rate of each of a plurality of distillates after switching when switching between oil types; a pre-preparation step for preparing in advance to receive the crude oil after switching, on the basis of the water content or flow rate of the crude oil after switching; a switching step to begin receiving the crude oil after switching; and an adjustment step for adjusting the operating conditions for distilling the crude oil after switching. In the adjustment step, the target setting value of a controlled variable for controlling a device for distilling the crude oil after switching is adjusted in accordance with a status value showing the status of the device.
