Existing Frame Work and Methodology: Description about failure work and its methodology here is the entire system is controlled manually. Because when we have to know the range of the temperature value or pressure value or any damages occurs in the plant it's been measured or controlled manually in the field which is mandatory. [...]the product is sent to the storage tank and the required amount of pure solvent is collected later from the product tank. Similar working for pressure relays and level relays[3,4] Connections for Hardware Prototype[8] * Main switch- i 0 * Temp low- i 4 * Temp high- i 5 * Flow high- i 6 * Flow low- i 7 * Level low- i 8 * Level high- i 9 * Output pump- 0 * Output heater- 1 Output valve- 2 Advantages of Proposed System: * Process done by automated mode * System runs smoothly and gives a good yield. * The process follows SHE (Safety Health Environment) policy. * Time consumption. * Safe environment when it is in automated mode. * In automated mode it depends on interlocks. [...]the product is sent to the storage tank and the required amount of pure solvent is collected later from the product tank. CONCLUSION AND FUTURE SCOPE: [...]we come to a conclusion that automatic control of distillation column helps the system run smoothly and gives a good yield.
