Process Engineer Trainee Interview Questions and Answers for Freshers

Two-phase and three-phase separators are equipment used to separate different phases in oil and gas processing.

• Two-phase separators separate gas and liquid phases, commonly used in oil production.

• Three-phase separators separate gas, oil, and water, essential in offshore platforms.

• Example of a two-phase separator: Horizontal separator used in oil fields.

• Example of a three-phase separator: Vertical separator used in gas processing plants.

• Efficiency in separation affects overall...read more

Understanding the process of different equipments involves analyzing pump curves to determine performance characteristics.

• Pump curves show the relationship between flow rate, head, and efficiency of a pump.

• They help in selecting the right pump for a specific application based on required flow rate and head.

• Pump curves also indicate the operating range of a pump and its efficiency at different operating points.

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

• Mass transfer involves the movement of substances from one phase to another, such as from liquid to gas or solid to liquid.

• It is important in processes like distillation, absorption, and extraction.

• Mass transfer is governed by principles like diffusion, convection, and interfacial mass transfer.

• Examples include the transfer of oxygen from air to water in aeration tanks and the separation of components in a ch...read more
