Industrial Process Design
In a typical scenario, an industrial process will use an extraction step in which solutes are transferred from the aqueous phase to the organic phase; this is often followed by a scrubbing stage in which unwanted solutes are removed from the organic phase, then a stripping stage in which the wanted solutes are removed from the organic phase. The organic phase may then be treated to make it ready for use again.
After use, the organic phase may be subjected to a cleaning step to remove any degradation products; for instance, in PUREX plants, the used organic phase is washed with sodium carbonate solution to remove any dibutyl hydrogen phosphate or butyl dihydrogen phosphate that might be present.

Famous quotes containing the words industrial, process and/or design:
“If you do not regard feminism with an uplifting sense of the gloriousness of woman’s industrial destiny, or in the way, in short, that it is prescribed, by the rules of the political publicist, that you should, that will be interpreted by your opponents as an attack on woman.”
—Wyndham Lewis (1882–1957)
“At last a vision has been vouchsafed to us of our life as a whole. We see the bad with the good.... With this vision we approach new affairs. Our duty is to cleanse, to reconsider, to restore, to correct the evil without impairing the good, to purify and humanize every process of our common life, without weakening or sentimentalizing it.”
—Woodrow Wilson (1856–1924)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
