Thermosyphon reboiler operation - Distillation Group

 · Product composition sets the sump temperature. The sump temperature is the result of mixing colder liquid from tray 1 with hotter liquid from the reboiler. Assuming the composition changes are small, the higher the recirculation rate, the lower the reboiler outlet temperature you need to get the mixed temperature to the product conditions.

The furnace tubes will also face shock due to expansion of carry over water to steam in the furnace. This will have negative impact on furnace tubes and over the times may lead to tube failure. For remedial action, if there is a water shot accompanying crude, the desalter temperature will drop sharply.

Vacuum distillation - Wikipedia

Vacuum distillation can also be referred to as "low-temperature distillation" In distilling the crude oil, it is important not to subject the crude oil to temperatures above 370 to 380 °C because of the high molecular weight components in the crude oil will undergo thermal cracking and form petroleum …

Fractional distillation - Wikipedia

Fractional distillation is the most common form of separation technology used in petroleum refineries, petrochemical and chemical plants, natural gas processing and cryogenic air separation plants. In most cases, the distillation is operated at a continuous steady state.New feed is always being added to the distillation column and products are always being removed.

trays, which contain perforations and bubble caps. Each tray permits vapors from below to bubble through the cooler, condensed liquid on top of the tray. This provides excellent vapor/liquid contacting. Condensed liquid flows down through a pipe to the hotter tray below, where the higher temperature causes re-evaporation.
