I applied via Referral and was interviewed before Apr 2021. There were 3 interview rounds.
GLR Reactor glass, solvent, SSR, filter types and permits used in industry.
GLR Reactor uses borosilicate glass
Solvent used in the company depends on the process and can vary
SSR used in the industry can be of different types such as solid-state relay or single-shot rifle
Different solvents have different boiling points, for example, water boils at 100°C while ethanol boils at 78.37°C
Sparkle filter is used for coarse filt...

Unit operations involve physical changes in the material, while unit processes involve chemical changes.
Unit operations involve physical processes like mixing, crushing, distillation, filtration, etc.
Unit processes involve chemical reactions like oxidation, reduction, hydrolysis, etc.
Unit operations are usually used in the initial stages of production, while unit processes are used in the later stages.
Unit operations f...
Types of reactors include batch reactors, continuous stirred-tank reactors, plug flow reactors, and fluidized bed reactors.
Batch reactors: Used for small-scale production and testing.
Continuous stirred-tank reactors: Ideal for continuous production with uniform mixing.
Plug flow reactors: Allow for efficient heat transfer and minimal back-mixing.
Fluidized bed reactors: Suitable for high-temperature reactions and catalys
Types of agitators include paddle agitators, anchor agitators, turbine agitators, and propeller agitators.
Paddle agitators are used for low viscosity fluids and gentle mixing.
Anchor agitators are used for viscous fluids and provide good radial mixing.
Turbine agitators are used for high viscosity fluids and provide high shear mixing.
Propeller agitators are used for low viscosity fluids and provide axial flow mixing.
Gas drying is used to remove moisture from gases, while steam drying is used to remove moisture from solids or liquids.
Gas drying involves passing a gas stream through a desiccant material to remove moisture, commonly used in natural gas processing.
Steam drying involves using steam to evaporate moisture from solids or liquids, commonly used in food processing or paper production.
Gas drying is more suitable for removing...
Heat exchangers are devices used to transfer heat between two or more fluids at different temperatures.
Types of heat exchangers include shell and tube, plate heat exchangers, and finned tube heat exchangers.
Shell and tube heat exchangers consist of a shell with tubes running through it, allowing one fluid to flow through the tubes while another flows over the tubes.
Plate heat exchangers use metal plates to transfer hea...

Seals are used to prevent leakage in pumps and other equipment. Affinity law relates to pump performance. Seal parameter refers to seal design.
Types of seals include mechanical seals, lip seals, and labyrinth seals.
Affinity law states that pump flow rate is directly proportional to speed, and head is proportional to the square of speed.
Seal parameter includes factors such as seal face material, spring design, and seal ...

Distillation is a separation process used in chemical engineering to separate components of a liquid mixture based on their boiling points.
Distillation is a separation technique used to purify liquids or separate liquid mixtures.
It relies on the differences in boiling points of the components in the mixture.
The process involves heating the mixture to vaporize the more volatile component and then condensing it back into...
Chemical processes involve the transformation of raw materials into useful products using chemical reactions.
Examples of chemical processes include distillation, fermentation, and polymerization.
Valves are commonly used in chemical processes to control the flow of fluids.
pH is a measure of the acidity or basicity of a solution.
Types of pumps used in chemical processes include centrifugal pumps, positive displacement pu
Answering questions related to starting pump, two phase flow, control station work, ejector problem and troubleshooting, and vacuum in column.
To start a pump, ensure that the suction line is filled with liquid and open the discharge valve. Then, turn on the motor and gradually open the suction valve.
Two phase flow is when both liquid and gas are present in the pipe. This can cause issues with pump performance and requi...

TSDF site stands for Treatment, Storage and Disposal Facility site.
TSDF site is a facility that handles hazardous waste materials.
It is responsible for the proper treatment, storage, and disposal of hazardous waste.
These sites must comply with strict regulations and guidelines set by the EPA.
Examples of hazardous waste that may be handled at a TSDF site include chemicals, pesticides, and radioactive materials.
