Embodiment 1

[0065] Adopt the method of the present invention, be used to carry out the prediction of dry point of atmospheric tower top by logging in prediction system; Said prediction system is installed on the server, and server is connected with the server of real-time database system, LIMS system respectively by network cable, and client is 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 dry point at the top of the column, including the feed temperature of the atmospheric column, the return flow rate at the top of the atmospheric pressure, the pressure at the top of the column, the temperature at the top of the column, the amount of steam at the bottom of the column, and the amount of steam at the bottom of the column. Top-to-reflux ratio.

Abstract

The invention relates to an atmospheric and vacuum distillation unit atmospheric pressure tower top dry point prediction method. In the prior art, there is no atmospheric pressure tower top dry point soft measurement method. By using the method of the invention, the above problem is solved. In the atmospheric and vacuum distillation unit atmospheric pressure tower top dry point prediction method, through a registration prediction system, atmospheric pressure tower top dry point prediction is performed. A prediction system is installed on a server. The server is connected to servers of a real-time database system and an LIMS system through a cable. A client is a computer and a mobile terminal with an authority so that the above problem is well solved, and the method can be used in an atmospheric and vacuum distillation unit.

Description

technical field [0001] The invention relates to a method for predicting the dry point at the top of an atmospheric pressure tower of an atmospheric and vacuum device. Background technique [0002] In the atmospheric and vacuum device, the dry point of oil at the top of the atmospheric tower is the main quality control index of the constant top product, which mainly reflects the weight of the oil produced, so the quality of its control is not only related to the extraction of crude oil from the atmospheric tower rate, while affecting the subsequent processing. At present, there is no suitable instrument that can give real-time measurement values ​​for dry points, 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 then input into the LIMS system. In addition, the cycle of manual analysis is generally every 4 hours or 8 hours. Therefore,...
