Question 1 Sketch a P&ID to represent the following system: Natural gas from a transmission pipeline is to be separated from any potential liquid using a two- phase vertical separator.

Liquid is to flow out the base of the vessel under level control. The vapour phase will leave via the top of the vessel with the following instrumentation feeding back to the control system: i. ii. iii. Flow iv. Gas composition via gas chromatograph analysis Relevant Data • Use the NG P&ID Legend Sheet. All equipment, valves, instruments, and lines are to be tagged. Pressure Temperature • The two-phase separator is equipped with a PSV that vents safely to atmosphere, set at vessel design pressure ➜ Vessel details: ● • Design pressure: 15,300 kPag / FV Design temperature: -10/70°C Material: carbon steel Diameter: 1,200 mm • Height (T-T): 3,000 mm ● Question 2 Sketch a P&ID to represent the following system: A water and ethanol mix is to be pumped using a centrifugal pump from the base of a vertical vessel under level control, through a pre- heater (heat exchanger with steam as the heating medium) to a set product temperature before entering a distillation column. Details on the upstream vessel and distillation column are not required. Relevant Data • Use the NG P&ID Legend Sheet. All equipment, valves, instruments, and lines are to be tagged.
