Eternis Fine Chemicals Production Officer Interview Questions, Process, and Tips for Experienced

The plant is a manufacturing facility that produces products through a series of processes.

• The plant has multiple production lines that operate simultaneously

• Raw materials are received and stored in the warehouse before being processed

• The production process involves mixing, heating, cooling, and packaging

• Quality control checks are performed at various stages of the process

• Finished products are stored in the finished go

Mass transfer is the movement of substances from one place to another.

• Mass transfer involves the movement of components in a system due to differences in concentration, pressure, or temperature.

• Examples include the diffusion of gases in air, the separation of components in distillation processes, and the absorption of gases in liquids.

• Mass transfer is important in various industries such as chemical engineering, food p

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the 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, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distilla...read more

There are various types of valves used in different industries for controlling the flow of fluids or gases.

• Gate valve

• Ball valve

• Butterfly valve

• Check valve

• Globe valve

• Diaphragm valve

• Plug valve

• Needle valve

• Pressure relief valve

• Safety valve

Pressure units are used to measure the force exerted on a surface per unit area.

• Pressure is typically measured in units such as pascal (Pa), bar, psi, or atmosphere (atm).

• 1 pascal (Pa) is equal to 1 newton per square meter (N/m²).

• 1 bar is approximately equal to atmospheric pressure at sea level (1 atm).

• 1 psi (pound per square inch) is equal to approximately 6895 pascals (Pa).

The fire triangle is a model that explains the three elements required for a fire to start and continue. Diamonds are a form of carbon that is highly valued for their beauty and durability.

• The fire triangle consists of three elements: fuel, heat, and oxygen.

• If any of these elements are removed, the fire will be extinguished.

• Diamonds are formed deep within the Earth's mantle and are brought to the surface through volcan...read more

The Bernoulli equation relates the pressure, velocity, and elevation of a fluid in a streamline.

• The Bernoulli equation is a fundamental equation in fluid dynamics.

• It states that the total energy of a fluid remains constant along a streamline.

• The equation relates the pressure, velocity, and elevation of the fluid.

• It is derived from the principle of conservation of energy.

• The equation is commonly used in various applicat...read more

There are numerous types of unit operations and unit processes in production.

• Unit operations involve physical changes to materials, such as mixing, filtration, and distillation.

• Unit processes involve chemical changes, such as oxidation, reduction, and hydrolysis.

• Examples of unit operations include crushing, grinding, and drying.

• Examples of unit processes include fermentation, polymerization, and chlorination.
