Distillation types include simple, fractional, steam, vacuum, and molecular distillation.

• Simple distillation is used for separating liquids with different boiling points.

• Fractional distillation is used for separating liquids with similar boiling points.

• Steam distillation is used for separating volatile compounds from non-volatile ones.

• Vacuum distillation is used for separating liquids with high boiling points.

• Molecular...read more

Safety interlocks of a chiller ensure safe operation by monitoring various parameters and shutting down the system in case of any abnormalities.

• Safety interlocks monitor parameters such as temperature, pressure, and flow rate to ensure safe operation.

• If any parameter exceeds safe limits, the interlock system will shut down the chiller to prevent damage or accidents.

• Examples of safety interlocks include high-pressure cu...read more

Boiler is a closed vessel where water is heated to generate steam. Safety measures include regular maintenance, pressure relief valves, and water level controls.

• Boilers heat water to generate steam for heating or power generation

• Safety measures include regular maintenance to prevent leaks or malfunctions

• Pressure relief valves release excess pressure to prevent explosions

• Water level controls ensure proper water levels t

Preventive maintenance is planned maintenance to prevent breakdowns, while breakdown maintenance is reactive maintenance after a breakdown occurs.

• Preventive maintenance is scheduled in advance to prevent equipment failure.

• Breakdown maintenance is performed after a breakdown has already occurred.

• Preventive maintenance helps in reducing unexpected downtime and prolonging equipment life.

• Breakdown maintenance can be costly...read more

Cooling tower performance can be measured by monitoring key parameters such as temperature differentials, flow rates, water quality, and energy consumption.

• Monitor temperature differentials between the inlet and outlet water to ensure efficient heat transfer.

• Measure flow rates to ensure proper water circulation and cooling capacity.

• Regularly test water quality for factors such as pH, conductivity, and microbial growth ...read more
