AI Technical Summary

Technical Problem

The existing ethyl silicate purification process in multi-stage distillation tower systems takes a long time to adjust parameters, resulting in fluctuations in the performance of the output product.

Method used

A distillation tower is set up in series with four stages. A condenser is provided at the top of the distillation towers at each stage and a reboiler is provided at the bottom. The operating parameters are detected through the top temperature sensor, the bottom temperature sensor and the pressure sensor, the main control distillation tower and other types of distillation towers are defined, and a static, dynamic and conditional trigger adjustment strategy is implemented to ensure that the operating parameters of distillation towers at each stage meet the preset interval.

Benefits of technology

Through the combined adjustment of multi-stage distillation tower, it can be quickly adjusted to a stable state, reducing repeated adjustment processes, reducing regulation time, and improving product performance stability.

Abstract

The invention relates to the technical field of solvent purification, and discloses a purification control method of ethyl silicate and provides a purification device.The purification control method comprises the steps that operation parameters of all rectifying towers are detected respectively, and the operation parameters comprise the reflux ratio, the tower top temperature, the tower bottom temperature and the pressure in the towers; taking the rectifying tower with the maximum deviation degree as a main control rectifying tower, and respectively defining other rectifying towers as static rectifying towers, dynamic rectifying towers or condition triggering rectifying towers according to the relative positions of the other rectifying towers and the main control rectifying tower and a preset contrast relationship; when the controlled parameters of the active rectifying tower are adjusted, the operation parameters of the other rectifying towers are detected synchronously, the static rectifying tower is adjusted according to a preset static adjusting strategy, and the static adjusting strategy, the dynamic adjusting strategy and the condition triggering adjusting strategy are executed repeatedly till the parameters and all levels of rectifying towers meet the preset operation parameters.
