Phase diagrams were constructed using Capryol 90 as the oil phase and Tween 20 and Carbitol as the surfactant and cosurfactant, respectively. No distinct conversion from w/o to o/w nanoemulsions was observed. The rest of the region on the phase diagram represents the turbid and conventional emulsions.
A Block Flow Diagram (BFD)—sometimes referred to as an Iconic Flow Diagram—provides an outline of a process on just one or two sheets. It is not to scale and will contain only very limited engineering and process information. A BFD generally consists of the following: • Symbols for the larger equipment items or for groups of equipment.

Solid-self-emulsifying drug delivery system (S-SEDDS) of paclitaxel (Ptx) was developed by the spray drying method with the purpose of improving the low bioavailability (BA) of Ptx. 10% oil (ethyl oleate), 80% surfactant mixture (Tween 80 : Carbitol, 90 : 10, w/w), and 10% cosolvent (PEG 400) were chosen according to their solubilizing capacity. The mean droplet size, zeta potential, and ...
Figure 9.11.1-2 is a schematic diagram of the process used to prepare soybeans for the solvent extraction process. The process, which is fairly well standardized, consists of four principal operations: cracking, dehulling/hull removal, conditioning, and flaking. Soybeans are conveyed from the process bins to the mill by means of belts or mass flow

Use: Eastman™ DE Solvent (Diethylene Glycol Monoethyl Ether) is a very polar, slow evaporating, water miscible solvent with a low odor. It is an active solvent for cellulose acetate butyrate, nitrocellulose, epoxy resins, and other coating materials.
The volume flow rate of a fluid is defined to be the volume of fluid that is passing through a given cross sectional area per unit time. The term cross sectional area is just a fancy term often used to describe the area through which something is flowing, e.g., the circular area inside the dashed line in the diagram …
See a more detailed flow diagram in your textbook along with a description of the operating conditions in the commercial process. As the first step in deasphalting, residue (feedstock) is mixed with four to eight times the volume of liquid propane. Heavier residua require a higher solvent to residue (S/R ) ratio for effective separation of asphalt.
by the McCabe-Thiele Diagram. It is now proposed to demonstrate how the extraction and strip isotherms can be used to both design a solvent extraction circuit and to predict the performance of that circuit. The problem in the randomly chosen example to be shown, is how to treat an aqueous liquor containing 12 gpl Cu++ and about 1.6 gpl free H2SO4.
CARBITOL™ Solvent. Solvent used to facilitate penetration into fibers and to promote the production of intense, bright shades; it features a high boiling point and low vapor pressure.
