A mah production control method and device

Abstract

This application discloses a MAH production control method and device, which obtains the current water vapor data of the MAH production device, inputs the current water vapor data into the water vapor balance calculation model established by using the historical water vapor data, and calculates the extra water replenishment required by the MAH production device Adjust the opening of the external water delivery valve of the MAH production unit according to the external water replenishment amount. Adjusting the optimal control of the opening of the external water delivery valve of the MAH production device through the external water replenishment can ensure that the water vapor balance in the MAH production device is in good condition, and then ensure that the steam pressure in the main pipe is stable and the steam flow during the operation of the MAH production device is stable. Therefore, the stability of steam pressure and the utilization rate of steam energy are improved, and the automatic calculation of water vapor balance is realized. Secondly, the amount of supplementary water calculated based on the water-vapor balance calculation model does not require human experience to judge, reducing manual intervention factors in the steam system and avoiding water waste caused by manual adjustments.

Description

technical field [0001] The invention relates to the technical field of maleic anhydride (Maleic anhydride, MAH) production, and more specifically, relates to a MAH production control method and device. Background technique [0002] Maleic anhydride, also known as maleic anhydride, is an important basic organic chemical raw material, which can be widely used as raw material, additive and intermediate in the production of papermaking, paint, medicine, food and daily necessities. [0003] At present, the traditional MAH production device uses manual adjustment of the external water delivery to maintain the water vapor balance of the steam system. Manual adjustment of the external water delivery is adjusted by the craftsman based on experience, and the adjustment accuracy is not enough to meet the needs of real-time precise control. Secondly, manual Conditioning wastes water. Contents of the invention [0004] In view of this, the embodiment of the present application provide...
