What is the role of a suction knockout vessel?

• A. To increase gas pressure in pipelines
• B. To separate entrained liquid from gas
• C. To enhance gas quality for transport
• D. To filter contaminants from liquids

Answer: (B)

A suction knockout vessel plays a critical role in the processing of gas by effectively separating entrained liquids from the gas stream. This separation is essential because gas pipelines need to transport gases in their vapor phase without any liquid carryover, which could lead to issues such as corrosion, reduced efficiency, or even operational hazards. When gas is extracted from the ground or processed, it often contains water, hydrocarbons, or other liquids that can be entrained in the gas flow. The suction knockout vessel is specifically designed to remove these liquids. As the gas enters the vessel, the design allows for a decrease in velocity and a change in pressure, which enables the heavier liquids to settle at the bottom of the vessel, effectively separating them from the gas. The liquids collected can then be drained and managed appropriately, while the gas continues on its path to further processing or transport. This separation not only helps in maintaining the integrity of the pipeline but also ensures that the quality of the gas being transported is optimal, which is vital for transmission and distribution systems.
