MOF Synthesis Heating Process Control System Research

Abstract

In the chemical engineering territory, the important parameters regarding reaction are fundamentally temperature, pressure, and concentration, among which the setting and monitoring of reaction temperature are crucial to complete the reaction efficiently, safely, and quickly. MOF Synthesis, due to the different heating pattern or unstable heating, usually affects the rate of nucleation and crystallization, causing the difference of crystalline. For the temperature sensing module made in this system, to ensure the reliability, this project implements the monitoring with wireless ZigBee chip and wire DAQ data acquisition card. The terminal interface sends the control package to infrared emission module through RS-232, and the signals are sent to infrared receiving module through infrared emission module to implement the automatic control of heating oven. The practical results are: (1) complete the temperature sensing module made by J type thermal couple, (2) ZigBee wireless and DAQ Data Acquisition Card wire transmission technology, (3) completing the development of infrared receiving and emitting control module, (4) the interface designed for this system covers the functions, such as monitoring, controlling, and recording, (5) Remote monitoring and control implemented with internet, (6) MOF synthesis heating experience.
