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...
General Checklist the Essential Steps and precautions for Pre-start and Starting up the Centrifugal Pumps . # What’s the things you Should be attention physically? # General centrifugal pump start up procedure:- Before pump start-up you must perform these tasks:- *01. Open the suction valve , do priming by venting all the air inside the suction line by opening any vent or even the PG vent till liquid coming out then close , now you confirm no air inside the system to reduce the chances of pump getting cavitation *02. Open any re-circulation or cooling lines. *03. Fully close or partially open the discharge valve, depending on system conditions. *04. Start the driver. *05. Slowly open the discharge valve until the pump reaches the desired flow. *06. Check the pressure gauge to ensure that the pump quickly reaches the correct discharge pressure. *07. If the pump fail to reach the correct pre...
