Autonomous Flashpoint Detector

Abstract

The flash point is the lowest temperature at which a liquid can produce a flammable mixture with air through its vapors. This flash point temperature signifies how likely the test material is to create a flammable mixture with air when subjected to carefully controlled lab conditions. Consequently, the flash point of a substance hinges on the testing conditions and methods employed. The procedure for gauging the flash point is straightforward: A defined sample volume is placed into a test cup, which is held at the prescribed test temperature. After a specified duration, a test flame is introduced, and the presence or absence of a flash is noted. Flash point testing is utilized for a wide range of purposes, including quality control, hazard classification for transportation, compliance with waste disposal regulations, and contamination analysis. It stands as an essential testing method within the petrochemical industry. Petrochemical companies in Pakistan currently depend on foreign suppliers for acquiring flashpoint detection equipment. Consequently, the objective of this project is to design and manufacture an industrial-grade flashpoint detector locally. Our approach will involve employing electrical heating, a test flame, and temperature sensing mechanisms. The rate at which temperature changes will be tailored to the specific chemicals being tested and their respective flashpoint temperature ranges. To ensure precise temperature control, we will implement a PID (Proportional-Integral-Derivative) algorithm, which will effectively manage temperature fluctuations. Additionally, we will incorporate a user friendly Human-Machine Interface (HMI) for easy control, temperature adjustment, and other essential functionalities. Our ultimate aim is to create a flashpoint detector that can be manufactured within Pakistan, reducing the reliance on foreign suppliers in the petrochemical industry.
