The specific process for generating steam in atmospheric and vacuum distillation units
Thread Content
Could you provide a specific process flow diagram for the steam generation in the atmospheric and vacuum distillation unit?
Theoretically, it should be possible; both high-temperature heat and low-temperature heat are available；
High-temperature heat exchangers and hot water heat exchangers can produce low-pressure steam
It’s simple: after reaching thermal equilibrium, the excess heat can be used to generate steam through the heat exchanger (at the bottom) and the drum (at the top). Typically, 3.5 kilograms of steam are produced, and this steam can then be used to heat the convection section of the furnace for superheating; once superheated to 400°C, it is used as stripping steam in various towers.
Generally, intermediate-stage reflux is used to exchange heat with deoxygenated water to generate steam; for example, in units such as the second stage of normal pressure and the first stage of reduced pressure, the process is quite simple
