Factors affecting oil extraction/water adsorption
Oil yields gradually decreased with drier corn germ, whereas protein loss increased when corn germ MC was <1.12%. Reducing the number of extraction stages from seven (original SEP) to five did not affect ethanol drying capability, oil yields, and protein co-extracted with oil. Using ethanol/hexane blends resulted in more anhydrous ethanol, higher oil

Abstract The sequential extraction process (SEP) uses ethanol to extract oil and protein from cracked, flaked, and dried corn germ, and the dried corn germ simultaneously dehydrates the ethanol. Value‐added
Factors Which Affect Extent Of Adsorption, Chemistry
Factor Affecting Adsorption. Factors which affect the extent of adsorption . The following are the factors which affect the adsorption, (1) Nature of the adsorbate (gas) and adsorbent (solid) (i) In general, easily liquefiable gases e.g., CO 2, NH 3, Cl 2 and SO 2 etc. are adsorbed to a greater extent than the elemental gases e.g. H 2, O 2, N 2, He etc. (while chemisorption is specific in nature.)
Seven factors are known to influence the fate and behavior of pesticides in soil systems: (1) chemical decomposition, (2) photochemical decomposition, (3) microbial decomposition, (4) volatilization, (5) movement, (6) plant or organism uptake, and (7) adsorption. The phenomenon of adsorption-desorption directly or indirectly influences the
Understanding the factors affecting the adsorption
To evaluate the adsorption efficiency of several adsorbents towards La, desorption and regeneration of adsorbents should be given due consideration. The main objective of the review is to provide an insight into the important factors that may affect the recovery of La using various adsorbents.
1.3 FACTORS AFFECTING ADSORPTION The rate of adsorption onto carbon is slow. Nicol*7* showed that carbon isolated in a stage of a carbon-in- pulp plant had not reached equilibrium after 300 hours. It is for this reason that the rate of adsorption is the most important factor governing the design and optimiza tion of the adsorption circuit. The factors affecting adsorption can be broadly

During oil extraction, the high viscosity of crude oil cause major problems, affecting negatively the oil production rate. Many studies have focused on evaluating the properties of different crude oil grades and their production techniques.

The extraction process consisted of two extraction regimes, a fast regime and a slow regime, respectively. In the fast regime, the extraction rate was nearly constant. In the slow regime, the extraction rate decreased rapidly. This may be because there was much oil on the surface of particles after grinding and the remaining oil was

Water is often transported by trucks, which bring water to the oil or gas well for drilling and hydraulic fracturing, and take used or produced water away for treatment, reuse, and/or disposal. In areas with many established wells, pipelines may be installed to transport water, improving efficiency and safety, and decreasing truck traffic.
