10+ Compass Group Support Services Interview Questions and Answers

Yes, there are various types of reactors and their maintenance depends on the type.

• Types of reactors include batch, continuous stirred tank, plug flow, and fluidized bed reactors

• Maintenance can include cleaning, replacing parts, and monitoring performance

• For example, in a fluidized bed reactor, maintenance may involve replacing the bed material and monitoring gas flow

• Regular maintenance is important to ensure safe and efficient operation of the reactor

Total plant heat load is evaluated by considering all the heat sources and sinks in the plant.

• Identify all the heat sources and sinks in the plant

• Calculate the heat generated by each source

• Determine the heat absorbed by each sink

• Sum up all the heat generated and subtract the heat absorbed to get the total plant heat load

• Consider factors like ambient temperature, humidity, and insulation in the calculation

IBR and non IBR boilers are two types of boilers used in industries.

• IBR stands for Indian Boiler Regulations, which are a set of regulations governing the design, construction, and operation of boilers in India.

• IBR boilers are certified by the Indian government and must adhere to strict regulations, while non IBR boilers do not require certification.

• IBR boilers are generally used in industries where steam is required for process heating, while non IBR boilers are used for sma...read more

Validation parameters are criteria used to ensure accuracy, reliability, and consistency of data or results.

• Validation parameters include accuracy, precision, specificity, sensitivity, linearity, range, limit of detection, and limit of quantification.

• Accuracy refers to how close the measured value is to the true value.

• Precision refers to how close the measured values are to each other.

• Specificity refers to the ability of a method to detect only the target analyte.

• Sensitivity ...read more

Filtration rate is the rate at which a substance passes through a filter or membrane.

• Filtration rate is commonly used in industries such as water treatment, pharmaceuticals, and food processing.

• It is measured in units such as liters per hour or gallons per minute.

• Higher filtration rates indicate faster flow of substances through the filter.

• For example, a water filtration system may have a filtration rate of 10 liters per hour.

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

• Specific heat is a physical property of a substance.

• It is measured in J/kg°C or cal/g°C.

• Different substances have different specific heat values.

• Water has a high specific heat, which is why it is used to regulate temperature in living organisms.

• Metals generally have lower specific heat compared to water.

Power number is a dimensionless number used in fluid mechanics to characterize the ratio of inertial forces to viscous forces in a fluid flow.

• Power number is used to determine the efficiency of mixing in agitated tanks.

• It is calculated as the ratio of the power input to the fluid by the agitator to the product of the fluid density, impeller speed, and impeller diameter.

• A high power number indicates a more vigorous mixing process, while a low power number indicates less effici...read more

Distillation rate calculation involves determining the amount of material distilled over a certain period of time.

• Distillation rate is typically measured in units of mass or volume per unit time.

• It can be calculated by dividing the amount of material distilled by the time taken.

• For example, if 100 grams of a substance is distilled in 1 hour, the distillation rate would be 100 g/hr.
