Embodiment 1

[0065] Adopt the method of the present invention, be used to carry out the prediction of normal one-line flash point by logging in predicting system; Described predicting system is installed on the server, and server is connected with the server of real-time database system, LIMS system respectively through network cable, and client is authorized computer and mobile terminal; the working steps of the prediction system are as follows:

[0066] 1) Selected auxiliary variables

[0067] According to the field operator's control experience, consider the relevant auxiliary variables that actually have a greater impact on the flash point of the normal line, including the top temperature of the atmospheric column, the pressure at the top of the tower, the extraction temperature of the normal line, the reboiler temperature of the normal line, and the normal line Blow volume.

[0068] 2) Outlier elimination of auxiliary variable raw data

Abstract

The invention relates to a method for predicting a flash point of the first atmospheric pressure for an atmospheric tower in an atmospheric and vacuum distillation unit, and mainly solves the problem that no soft measurement method for the flash point of the first atmospheric pressure exists in the prior art. The method for predicting a flash point of the first atmospheric pressure for an atmospheric tower in an atmospheric and vacuum distillation unit is adopted to predict the flash point of the first atmospheric pressure through the login of a prediction system, the prediction system is installed on a server which is connected with a real-time database system and the server of an LIMS system through cables respectively, and clients adopt authorized computers and mobile terminals; the above technical scheme can solve the problem better, and the method for predicting a flash point of the first atmospheric pressure for an atmospheric tower in an atmospheric and vacuum distillation unit can be applied to the atmospheric and vacuum distillation unit.

Description

technical field [0001] The invention relates to a method for predicting the flash point of an atmospheric tower of an atmospheric and decompression device. Background technique [0002] In the atmospheric and vacuum unit, the distillate from the highest side line of the atmospheric column is called the normal line. The normal-line flash point of the atmospheric tower is the main quality control index of the normal-line products, which mainly reflects the weight of the oil produced, so the quality of its control is not only related to the extraction rate of crude oil in the atmospheric tower, but also affects the following Processing process. At present, for the flash point, there is no suitable instrument that can give the measured value in real time, and most refineries still rely on the manual analysis value of the laboratory. For manual analysis, it takes quite a long time, about 1h-2h, from on-site sampling to laboratory test results, and then input into the LIMS syste...
