1000 kg soyabeans containing 18% oil is processed in two stages:
1: Crushing and pressing of soybeans producing soybeans with 6% oil
2: Oil extraction using hexane producing hexane extracted oil and soybean meal containing 0.5% oil
Assuming the only process loss is oil loss in stage 1, calculate:
a. The amount of oil loss in stage 1 (in kg)
b. Yield of hexane extraction (%), which is calculated as the mass of hexane extracted
oil/mass of soybeans extracted

Immediate help needed balancing equations!
A feed of 10, 000 kg/day of soybeans is processed in a sequence of three stages or units. The beans contains 35 wt percentage protein, 27.1 wt Percentage carbohydrate, 9.4 wt Percentage fiber and ash, 10.5 wt Percentage water, and 18 wt Percentage oil. In the first unit, the beans are crushed and pressed to remove oil, resulting in a stream of pure oil and a stream of pressed beans (beans still contain 6 wt...

A Bean company carried out process to extract oil from fresh soybean containing 21 wt% soy oil. The extraction is using pure hexane, targeted to remove 90 % of the oil in a countercurrent multistages leaching process. The company prepare 1000 kg fresh soybean per hour and the final exit overflow solution is to contain 65 wt% soy oil. The slurry underflow is assumed N = -0.5 yA + 2. a) Calculate LO, LN, V1 and VN+1. b) Determine the...

4. In the production of soybean oil, beans containing 18.0 wt% oil and 82.0 wt% solids are ground and fed to a stirred tank (also called an extractor), along with a stream of liquid n containing recycled hexane and fresh hexane. The feed ratio is 4.2 kg hexane/kg beans. ground beans are suspended in the liquid, and essentially all of the oil in the beans is ex into the hexane. The stream exiting the extractor (also called the effluent) passes...

1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...
