Solaris Chemtech Interview Questions, Process, and Tips

Distillation is a process of separating components of a mixture based on their boiling points.

• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process can be used to purify liquids, separate mixtures, and extract essential oils.

• Examples include the production of ethanol from fermented grains and the purification o

Valves and pumps are essential components in production processes. There are various types of valves and pumps used in different applications.

• Types of valves: gate valve, ball valve, globe valve, butterfly valve, check valve, diaphragm valve

• Types of pumps: centrifugal pump, positive displacement pump, reciprocating pump, axial flow pump, gear pump

• Valves control the flow of fluids or gases, while pumps move fluids or ga...read more

Azeotropic distillation is a process used to separate two or more liquids with similar boiling points by adding a third component.

• It involves the use of a third component, called an entrainer, to break the azeotrope (constant boiling point) of the two liquids being separated.

• The entrainer forms a new azeotrope with one of the liquids, allowing the other liquid to be separated.

• Azeotropic distillation is commonly used in...read more

NPSH stands for Net Positive Suction Head. It is the difference between the pressure at the suction of a pump and the vapor pressure of the liquid being pumped.

• NPSH is a critical parameter in pump selection and operation.

• It determines whether the pump will cavitate or not.

• NPSH is affected by factors such as fluid temperature, pressure, and viscosity.

• If the NPSH available is less than the NPSH required, the pump will no...read more

Open loop is a control system where the output is not fed back to the input for correction or adjustment.

• Open loop control does not rely on feedback to make adjustments.

• It is a one-way communication system.

• Examples include a toaster, where the heating element operates for a fixed duration regardless of the toast's actual temperature.

• Another example is a washing machine with a timer that runs for a predetermined time wi
