Embodiment 1

[0065] The method of the present invention is used to predict the 10% point of the normal line by logging into the prediction system; the prediction system is installed on the server, and the server is connected to the real-time database system and the server of the LIMS system through a network cable, and the client is an active one. Authorized computers and mobile terminals; 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 10% point of the normal line. Including the top temperature of the atmospheric column, the top pressure, the constant first-line volume, the constant first-line extraction temperature and the normal first-line outlet reboiler temperature.

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

Abstract

The invention relates to a method for predicting a 10% 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 10% point of the first atmospheric pressure exists in the prior art. The method for predicting a 10% point of the first atmospheric pressure for an atmospheric tower in an atmospheric and vacuum distillation unit is adopted to predict the 10% 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 10% point of the first atmospheric pressure for an atmospheric tower in an atmospheric and vacuum distillation unit can be applied in the atmospheric and vacuum distillation unit.

Description

technical field [0001] The invention relates to a method for predicting the 10% point on the normal line of an atmospheric tower of an atmospheric and vacuum 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 10% point of the constant first line of the atmospheric tower is the main quality control index of the constant first 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 the crude oil in the atmospheric tower, but also affects the subsequent processing process. At present, for the 10% point, there is no suitable instrument that can give real-time measurement values, and most refineries still rely on manual analysis values ​​in laboratories. For manual analysis, it takes quite a long time, about 1h-2h, from on-site sampling to laboratory test results, and th...
