A chemicals (such as methanol, ethylene glycol, and others) regeneration plant is intended for components regeneration from their water solution.
Components regeneration is performed by a rectification method on identical process trains, the main element of which is a rectification column.
The product of the plant is a regenerated component with a high concentration of the basic substance which regeneration is intended for cutting operating costs of the technological process, the reduction of losses in the process of dehydration, and the feed of recovered component back into the process.
The recovery of the primary component from a saturated water solution is performed by the rectification of a two-component methanol/ethylene glycol and water mixture. The mixture separation is foreseen in the packed section of the column. The packing height in the rectifying and exhausting sections of the column provides for the plant design capacity and product quality.
As a rule, these plants are used in oil fields for the regeneration of hydrate inhibitors and absorption.
