I applied via Referral and was interviewed before Dec 2021. There were 2 interview rounds.
The question is about knowledge and experience in unit processes of chemical industry such as exothermic reactions, distillation, pump operation, valve types, production startup-shutdown process handling with MSDS.
Explain the process of exothermic reactions and how to handle them safely
Describe the distillation process and its importance in chemical industry
Explain the different types of pumps and their operating metho...
I am currently handling centrifugal pumps.
Centrifugal pumps are commonly used in industrial and commercial settings.
They work by converting rotational energy from a motor into kinetic energy to move fluid.
Examples of applications include water treatment, oil and gas production, and chemical processing.
Maintenance tasks include checking for leaks, monitoring vibration levels, and inspecting impellers.
Proper pump selecti...
API 610 and API 685 are the standards for process handling of centrifugal pumps.
API 610 is the standard for general-purpose centrifugal pumps used in the oil, gas, and petrochemical industries.
API 685 is the standard for sealless and magnetically driven centrifugal pumps used in hazardous and toxic applications.
Both standards cover design, materials, testing, and performance requirements for centrifugal pumps.
Other sta...
MSDS stands for Material Safety Data Sheet.
MSDS provides information about the hazards, handling, storage, and emergency procedures related to a particular material.
It is required by law for manufacturers and distributors to provide MSDS for hazardous materials.
MSDS includes information on the chemical composition, physical and chemical properties, and first aid measures.
It is important for workers to read and understa...
LEL stands for Lower Explosive Limit and UEL stands for Upper Explosive Limit.
LEL is the lowest concentration of a flammable substance in the air that can ignite and sustain combustion.
UEL is the highest concentration of a flammable substance in the air that can ignite and sustain combustion.
The range between LEL and UEL is known as the flammable range or explosive range.
Operating within the flammable range can pose si...

Questions related to reactor types, distillation, heat transfer, fire safety, work permits, and plant processes.
Types of reactors include batch, continuous stirred tank, and plug flow.
Types of distillation include simple, fractional, and vacuum distillation.
Vacuum distillation is used to separate compounds with high boiling points.
Vacuum pumps are used to create a vacuum in a system.
Exothermic reactions release heat, w...
I applied via Newspaper Ad and was interviewed in Dec 2023. There were 2 interview rounds.
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.
The components with lower boiling points will vaporize first and be collected, leaving behind components with higher boiling points.
Common examples of distillation include the production o...
