Stage Extractor

EQEX - Simple Equilibrium Stage Extractor System... [Pg.447]

The optimum recoverability of solute by a single-stage extractor is determined based on the K value and the E/R ratio. To increase the recoverability further, several extractors can be connected crosscurrently or countercurrently. [Pg.270]

The first stage overhead is heated by an exchange with hot solvent. The increase in temperature decreases the solubility of resins and high molecular weight aromatics. These precipitate in the second stage extractor. The bottom stream of this second stage extractor is recycled to the first stage. A portion of this stream can also be drawn as a separate product. [Pg.340]

The Sm solution is then adjusted to a pH of 0.23 followed by solvent extraction in a 6-stage extractor. The raffinate is about 95% S1TI2O3 which is precipitated as oxalate and ignited to obtain S1TI2O3. [Pg.46]

If we are satisfied with the amount of solute we have been able to extract from the solution in the single-stage extractor, then we are done. If we desire to extract more of the solute (i.e. we wish to achieve a smaller value of x j) then multiple stages might be used. Let s specify an arbitrarily small value for xj, the concentration of solute remaining after N stages. [Pg.191]

A single-stage extractor is used to extract component E from a feed stream. The feed and solvent stream compositions and flow rates are as follows ... [Pg.363]

A solvent is used to recover component E from a hquid feed containing components R and E by extraction in a single-stage extractor. The compositions and flow rates of the feed and solvent are given below ... [Pg.377]

A pure solvent 5 is used to remove component E from a binary liquid solution containing 30% mole E and 70% mole R. In a single-stage extractor how many kmol solvent per 100 kmol feed are required to bring the concentration of E in the raffinate to 3% mole What are the resulting rates and compositions of the raffinate and extract Use liquid-liquid equilibrium data from Figure 11.2. [Pg.377]

It is required to recover 93% of component E from a binary mixture of components E and R by treating with a solvent in a single-stage extractor. What is the required solvent rate per 100 kmol of feed, and what are the product rates and compositions Assume the liquid-liquid equilibrium... [Pg.377]

A four-stage extractor column is used to recover acetone from an acetone-chloroform solution using a water-acetic acid solution as the solvent. The feed and solvent are defined below, along with average k-values. Calculate the products component flow rates. [Pg.423]
