Abstract

A system that provides absorption dehydration is the glycol dehydration system, and a liquid desiccant inside the system provides a way to remove water from the system the circulation of fuel. The initial primary chemical in this system, ethylene glycol (HOCH CH OH) 2 2, has a very strong affinity for water. When in contact with a flow of water-moist herbal fueling, the ethylene glycol absorbs the water from the fueling circulation. Since technology has advanced, glycol dehydration now involves using an aqueous solution of a glycol by-product, where the glycol can be either Diethylene Glycol (DEG) or Triethylene Glycol. Initially, the system used ethylene glycol as the absorbent.

Introduction

In a contactor, Diethylene Glycol (DEG) or Triethylene Glycol (TEG) is delivered into contact with the fueling circulation that is moist with water. The glycol solution will absorb water from the moist fueling, sinking to the bottom of the contactor once it has done so. The herbal fueling, having lost the majority of its water content, is then transported out of the dehydrator. The glycol solution, which contains all the water that was removed from the herbal fueling, is put through a special boiler that is intended to vaporize only the water out of the solution. As a result of the boiling factor differential, the water is easily removed from the glycol solution, and the glycol is then recycled to the contactor.

Some units now have a flash tank separator-condenser that, in addition to removing water from the fueling circulation, also regenerates small amounts of methane and other compounds that the glycol solution occasionally mixes with it from the contactor level after having also removed those components from the fueling circulation. Previously, this methane may have been released into the atmosphere and lost to product streams in addition to contributing to air pollution. The flash tank separator-condensers enable removal of the absorbed hydrocarbon components before the glycol solution reaches the boiler, reducing the amount of methane and other compounds that are lost.

The stress is reduced in the flash tank separator, allowing the lower boiling hydrocarbon components (i.e., lower boiling than the glycol solvent), which allows the methane and other hydrocarbons to vaporize (flash) from the solution. The glycol solution is then sent to the boiler, which also has air- or water-cooled condensers. At this point, any remaining hydrocarbons are captured, combined with other hydrocarbon streams, fractionated, and sent to the various product streams. Due to the hydrocarbon components' higher molecular weight than methane, the addition of a flash-separatorcondenser machine to the system is a prized adaptation for the treatment of herbal fueling streams from tight formation. Similar to the "moist" and "wealthy" glycol method, which uses fuel that is wealthy in water, and the "dry" and "lean" glycol method. The glycol regenerator is also referred to as the scrubber, the separator as the scrubber, the glycol fueling absorber as the contactor, the column as the stripper, and the glycol regenerator as the glycol reconcentration. A two-segment separator is the first place the wet fueling goes so that the liquid can be removed from the fueling mixture. Using a three-segment separator is recommended if there is unfastened water present. Despite the mist eliminator on the pinnacle of the separator, a small amount of water vapor is present in the fuel leaving the separator

This still "moist" fuel then enters the glycol fueling absorber's lowest chamber, moves upward through the trayed or packed tower with the mist eliminator to remove any entrained glycol droplets from the fueling circulation, and finally exits the absorber's top chamber as dry fuel. Before the new, regenerated glycol enters the absorber, the dry fueling passes through a glycol cooler to cool it. On the other hand, dry glycol flows down the tower, absorbs water from the fuel mixture flowing upward, and then leaves the absorber at the bottom as rich glycol. After passing through a reflux condenser at the top of the still column, the rich glycol then flows into a flash tank where the majority of the entrained.

The wealthy glycol flows through the glycol filters and the wealthy-lean glycol exchanger after leaving the flash tank, where it exchanges heat with the fresh lean glycol. The water is then removed using distillation, and the glycol awareness is accelerated to meet the tilt glycol requirement after the rich glycol enters the glycol regenerator with the still column and is reboiled. A stripping vapor will most likely be required to resource the regeneration system for methods requiring fueling with extremely low water dew points
