Process Control of Nitrocellulose Acid Using Programmable Logic Controller

Abstract

This research is about designing a miniature model for production of nitrocellulose acid by mixing three acids (nitric, sulfuric, and oleum) using automatic control methods rather than the traditional ones. This is because it is safe and accurate compared tothe traditional method, which is considered more dangerous to humans when dealing directly with these acids. The main components used to design miniature model are Programmable Logic Controller (PLC),G-box, pumps, input/output modules, and sensors. Furthermore, the SimaticLadder Diagram produced by the Siemens company was used for programming and simulation. Practical results obtained proved that this method is more accurate and safer to produce nitrocellulose acid.
