DEVICE FOR AUTOMATIC CONTROL OVER THE OPERATIONAL MODE OF RECTIFYING COLUMNS Russian patent published in 2004 - IPC

FIELD: petrochemical industry.

SUBSTANCE: the invention presents a device for automatic control of a technological mode of rectifying columns and is dealt with the field of petrochemical industry. The device may be is used for automatic control over the operational mode of rectifying columns of initial distillation. The device contains a sensor to control consumption of an internal reflux. The device additionally contains a sensor of consumption of a bottom product, a gauge and a temperature controller of the raw material heating and a controller of a ratio of consumptions of the internal reflux and the bottom products. Output of the controller of the ratio depends on the task to the controller of temperature of heating. The given design of the device allows to improve quality of control over the process of initial separation of petroleum by stabilization of the operational mode in the zone of the column feed and to increase selection of light products from the atmospheric column and the vacuum gas oil from the vacuum column.

EFFECT: the invention allows to improve quality of control over the process of initial separation of petroleum and to increase output of light oil.
