ANS:C - and equilibrium lines are parallel.

The Height Equivalent to a Theoretical Plate (HETP) and the Height of a Theoretical Unit (HTU) are parameters used to quantify the efficiency of a distillation column. They are measures of the height of packing or the length of a theoretical plate required to achieve a certain degree of separation. HETP is the physical height of packing material (or theoretical plate) required to achieve the same separation efficiency as one theoretical plate. HTU, on the other hand, is the theoretical height of packing material (or theoretical plate) required to achieve the same separation efficiency as one theoretical plate. When HETP is numerically equal to HTU, it implies that the physical and theoretical heights of packing material (or theoretical plates) are the same, indicating a certain level of efficiency in the column. However, this condition is generally true only under specific circumstances, which are:

• lies below the equilibrium line: When the operating line lies below the equilibrium line, indicating that the actual concentrations of components in the column are lower than their equilibrium concentrations.

ANS:A - fluid flow control is required.

A globe valve is most suitable for applications in which fluid flow control is required. Here’s why:

• Fluid Flow Control: Globe valves are designed to allow precise control over the flow rate. The spherical body shape and the disk-type element can be moved in or out of the flow path, enabling the user to regulate the flow with high accuracy.

• Fluid contains dispersed solid particles: Globe valves are not ideal for fluids with dispersed solid particles because the particles can get trapped in the valve, leading to wear and potential clogging.
• Valve is required to be either fully open or fully closed: While a globe valve can be used in fully open or fully closed positions, it is not the most efficient choice for such applications. Gate valves or ball valves are typically better suited for applications requiring a valve to be either fully open or fully closed.
• One way flow is required: Check valves are more appropriate for ensuring one-way flow. Globe valves do not inherently ensure one-way flow as they are designed for throttling and regulating flow.
