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...
Pump Cavitation And Prevention. Preventing cavitation of a pump is a significant operation for the smooth and efficient operation of a pump. Failure to prevent sin cavitation can result in complete damage to the pump impeller or pump. Which prevents any process from running smoothly. The term pump cavitation refers to conditions within the pump that where the actual suction pressure drop below the vapor pressure of the liquids, at the corresponding temperature. Abnormal sound, vibration occur in the pump during cavitation, and delivery pressure and flow rate decrease. # The suction pressure drop May be produced by one of the following reasons: An increase in the static lift of the centrifugal pump. A decrease in the atmospheric pressure with a rise in the altitude. A decrease in the absolute pressure in the system. As in the case of pumping from closed vessels. An increase in the temperature of the pumping liquid and Increase in velocity by speeding up the pump. The Net Po...
