【Daily Question No. 313】November 15, 2018: Briefly describe the function of a reboiler. It is used to heat the liquid at the bottom of the tower, causing it to partially vaporize; this provides heat to the tower and compensates for any insufficient evaporation area at the bottom of the tower. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

A reboiler, also known as a regenerator, is a special type of heat exchanger that features an evaporation space; it involves a heat transfer process accompanied by phase changes. It is usually located at the bottom of a distillation tower to generate steam for reflux. Classified by circulation mode: it can be divided into forced circulation and natural circulation. Forced circulation involves using a pump to forcibly extract the fluid from the tower and send it to the reboiler for heating and recycling ； Natural circulation relies on the density difference between the gas and liquid phases in the reboiler for circulation; the gas phase returns to the bottom of the tower, while the liquid at the bottom of the tower enters the reboiler to be heated and vaporized. Commonly used heating media include: steam, hot water, hot oil, liquid metals or molten salts, hot flue gas, and specialized heat exchange media.

The heavy components in the liquid phase at the bottom of the distillation tower are vaporized; the gas phase flows upward and undergoes multiple cycles of partial vaporization and partial condensation with the light component liquid phase coming from the reflux tank, on the tray or packing layer, thereby achieving a high degree of purity in the separation of the mixture

The heavier components in the liquid phase at the bottom of the distillation tower are vaporized; the gas phase flows upward and undergoes multiple cycles of partial vaporization and partial condensation with the lighter component liquid phase coming from the reflux tank, on the tray or packing layer, thereby achieving a high-purity separation of the mixture.
The function of the reboiler is to supply heat to heat the glycol-rich mixture to a certain temperature, thereby vaporizing the water absorbed by the glycol solution and allowing it to be discharged from the top of the distillation tower. In addition, the reflux vaporization heat load and additional heat dissipation losses must also be provided.
A reboiler (also known as a boiling reactor) is, as the name implies, a device that vaporizes a liquid once again. Its structure is similar to that of a condenser, but while the latter is used for cooling, a reboiler is used to heat and vaporize.
