Extractor with settling zone near solvent discharge
An extractor may have a home that keeps a solvent pool where solids material being processed is sprinkled through operation. One or more mattress decks could be positioned inside of the home to present multiple extraction phases. In certain cases, the mattress decks have been ordered to supply 1 mattress deck positioned at a vertically elevated position relative to some other bed deck, thereby supplying a drop zone in which the solids material passing through the system falls from the vertically elevated bed deck into a decrease bed deck. To lessen the number of solids material passing through the drop zone which becomes entrained from the solvent, the exactor could be configured with a settling zone. In certain cases, the settling zone is formed by truncating the period of the vertically elevated bed deck, giving enhanced space and home time for the solids material to fall out of suspension.

BACKGROUND
A variety of different industries use extractors to extract and recover liquid chemicals entrained inside solids. By way of instance, manufacturers of oil from renewable organic sources utilize extractors to extract oil from oleaginous matter, such assoybeans, rapeseed, sunflower seed, peanuts, cottonseed, palm kernels, and corn germ. The oleaginous matter is contacted by an organic solvent inside the extractor, causing the oil to be extracted from a nearby mobile structure into the organicsolvent. As another instance, extractors are utilized to recover asphalt from shingles and other petroleum-based waste substances. Normally, the petroleum-based substance is ground into small particles and then passed via an extractor to extract theasphalt from the solid substance into a surrounding natural solvent.
Regardless of the application where an extractor is used, manufacturers and operators of extractors are always looking for ways to improve the financial efficiency of the extractor operation. This may entail controlling the extractorto optimize the amount of extract recovered from a given feedstock when reducing the quantity of solvent lost during recovery and extraction. This can also involve operating the extractor harder by raising the feedstock flow rate through theextractor. Unfortunately, efforts to increase feedstock flow rate through an extractor frequently result in a corresponding drop in extract healing. This may occur when the feedstock doesn’t have sufficient residence time within the extractor and/orthe increased feedstock quantity inhibits proper intermixing between the extraction solvent as well as the feedstock.
