Embodiment Construction

[0031] The new method proposed by the present invention will be described below in conjunction with an industrial application example of atmospheric pressure furnace beacon control.

[0032] In a hydrorefining unit, after the raw material passes through the hydrogenation reaction part, it enters the separation unit for atmospheric and vacuum separation. Before the oil enters the atmospheric tower, it needs to be heated to the temperature required by the process. The schematic diagram of the atmospheric furnace is as follows figure 1 As shown, the furnace inlet feed is respectively provided with a flow measuring instrument FI_IN and a temperature measuring instrument TC_IN, which measure the change of the fuel at the inlet of the atmospheric furnace in real time, and the furnace outlet temperature TC_AFO is adjusted by the fuel gas valve. Affected by the upstream fluctuations of the atmospheric furnace, the oil flow and temperature at the inlet of the atmospheric furnace will al...

Abstract

The invention discloses a beacon tower control method for an atmospheric pressure furnace and belongs to the technical field of production of process industry. FI_IN(a feed oil flowmeter) and TC_IN(afurnace inlet oil temperature gauge) are arranged between a feed inlet of the atmospheric pressure furnace and a beacon tower controller of the atmospheric pressure furnace, TC_AFO( furnace outlet temperature controllers) are respectively arranged between an atmospheric pressure tower and the beacon tower controller of the atmospheric pressure furnace as well as between the beacon tower controllerof the atmospheric pressure furnace and a fuel gas regulating valve. On the basis of the static and dynamic balance concept of materials and energy of the overall system, the beacon tower control method, aiming to realize stable running of the whole process, can quickly acquire information of working conditions of the upstream units and carry out beacon tower control in time when working conditions of the upstream units change according to dynamic relation among units of the upstream and the downstream of the atmospheric pressure furnace, and accordingly can realize integrally intelligent control of the upstream production process and the downstream production process in cooperation.

Description

technical field [0001] The invention belongs to the technical field of process industrial production, and relates to a method for controlling the beacon of an atmospheric pressure furnace, which can be applied to the control scheme design of an atmospheric furnace in a process industrial production device. Background technique [0002] In the production process of the oil refining unit, the atmospheric pressure furnace is the key equipment affecting the fractionation effect of the target product. Therefore, the efficient and stable operation of the atmospheric pressure furnace is very important. In the daily operation of the atmospheric furnace, the stable control of the furnace outlet temperature has always been a key indicator to measure the smooth operation of the heating furnace. The stable control level of the furnace outlet temperature is directly related to the normal operation of the downstream atmospheric tower unit. Usually, the heat source of the atmospheric furna...
