In a pump overfeed design, what would be the correct name for the vessel that feeds liquid to the heat exchangers?

In a pump overfeed design, the vessel that feeds liquid to the heat exchangers is typically referred to as a recirculator. This term is used because the system involves circulating the liquid to maintain a proper flow rate and temperature through the heat exchangers. The function of the recirculator is crucial as it ensures that the heat transfer is efficient and consistent, allowing for optimal performance of the heat exchangers.

The design's primary goal is to keep the necessary liquid volume in motion, which is critical for effective heat exchange. A recirculator effectively helps achieve this by sending the liquid back to the heat exchangers where it can be heated or cooled as required. This constant circulation aids in preventing stagnation and ensures that the thermal properties of the liquid remain stable throughout the process.

In the context of the other terms, an accumulator usually serves the purpose of storing a certain volume of liquid at pressure, a surge drum helps manage fluctuations in flow rate and provide a buffer, and a high-pressure receiver collects vapor or gas. While each of these vessels has its own important role in various systems, they do not specifically denote the function of delivering liquid to heat exchangers in a pump overfeed design.
