Principle Of Industrial Catalyst And Classification Of Catalyst. Principle Of Industrial Catalyst : An industrial catalyst is a substance that accelerates a chemical reaction without undergoing any significant change in its own chemical composition. Catalysts work by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate. They provide an alternative pathway for the reaction to take place, which requires less energy and allows the reaction to proceed at milder conditions such as lower temperatures and pressures. Industrial catalysts are used in a wide range of chemical processes, including petrochemicals, refining, polymerization, and environmental applications. Classification Of Industrial Catalyst : Industrial catalysts can be classified into four main groups: 01. Homogeneous catalysts. Homogeneous catalysts are soluble in the reaction medium and are used mainly in the production of fine chemicals and pharmaceuticals. 02. Heteroge...
#Control valve has 3 basic Components: 01. Actuator Most actuators are pneumatic. Usually, an actuator works with the help of a diaphragm and instrument air. This is the device that positions the throttling element (i.e., the valve plug inside the valve body). 02. Valve body subassembly This is the part where the valve plug, valve seats, and valve casing are located. 03. Accessories These include positioners, I/P (current- to-pressure) transducers, and position sensors. #2 types of control valves are based on their motion:- 01. Linear-Motion valves as- A- Gate Valves. B- Diaphragm Valves. C- Globe Valves. 02. Rot...
