Mixer-settler scheme. Mixer settlers are a class of mineral process equipment used in the solvent extraction process. A mixer settler consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity.
Soybean meal, or soymeal, is the material remaining after solvent extraction of oil from soybean flakes, with a 50% soy protein content. The meal is 'toasted' (a misnomer because the heat treatment is with moist steam) and ground in a hammer mill. Ninety-seven percent of soybean meal production globally is used as livestock feed. [158]
Soybean oil, meal and beans. To produce soybean oil, the soybeans are cracked, adjusted for moisture content, heated to between 60 and 88 °C (140 and 190 °F), rolled into flakes, and solvent-extracted with hexanes. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially ...

Soybean meal. Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal. [1] Soybean meal is produced as a co-product of soybean oil extraction. [2]
The most common solvent is petroleum-derived hexane. This technique is used for most of the "newer" industrial oils such as soybean and corn oils. After extraction, the solvent is evaporated out by heating the mixture to about 149 °C (300 °F). [29] Supercritical carbon dioxide can be used as a non-toxic alternative to other solvents. [30]
She helped develop a solvent extraction process to remove highly toxic cesium-137 from the high-level waste stored at the Savannah River Site; as a result, the industrial process developed under ...
Typically for solvent extraction processes in stage-wise equipment such as the centrifugal contactor, you would have multiple contactors in series for extraction, scrubbing, and stripping (and perhaps others). The number of stages needed in each section of the process would depend on process design requirements (necessary extraction factor).
