Spill back control in DCS SYSTEM is a feature that prevents overflow of material in a process by controlling the flow back into the system.

• Spill back control is used in DCS (Distributed Control System) to manage the flow of material within a process.

• It helps prevent overflow or spillage by regulating the flow back into the system.

• This feature ensures efficient and safe operation of the process by maintaining proper material levels.

• Examples include controlling the flow of liqu...read more

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps use a rotating impeller to create flow and increase pressure.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps move fluid parallel to the impeller shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial flow pump - propeller pump

An exothermic reaction is a chemical reaction that releases energy in the form of heat.

• Exothermic reactions release heat to the surroundings

• They have a negative change in enthalpy (ΔH)

• Examples include combustion reactions, neutralization reactions, and some oxidation reactions

Clean rooms are controlled environments used in industries like pharmaceuticals and electronics to prevent contamination.

• Clean rooms are designed to maintain a specific level of cleanliness by controlling factors like air quality, temperature, and humidity.

• Workers in clean rooms must wear special clothing like gowns, gloves, and hairnets to prevent contamination.

• Equipment and materials used in clean rooms must be sterilized before entering to avoid introducing contaminants.

A mechanical seal is a device that helps prevent leakage between a rotating shaft and a stationary part in a pump or other equipment.

• Mechanical seals are commonly used in pumps, mixers, and other rotating equipment to prevent leakage of fluids.

• They consist of two main parts: a stationary part attached to the pump housing and a rotating part attached to the shaft.

• The seal faces are typically made of materials like carbon, ceramic, or tungsten carbide to withstand the friction ...read more
