35. The driving forces in the end sections required by the ETD and the EoF column designs cannot be realized for plate numbers close to Nm-m, where a conventional column is the only possibility. A total of 17 plates was chosen because it is around the minimum number of plates which is necessary in order to use ETD and the EoF operation in the complete column and not only in the middle of the rectifying and stripping sections.
36. In brief, a hot vapor stream rich in the light component is now fed further down into a column separating HC1 from vinyl chloride monomer (VCM) and ethylene dichloride (EDC) at Norsk Hydro Rafnes. The chemical potential of the light component in the feed stream matched better with the chemical potential in the bottom of the column (although the concentration match was better further up). The heat of the vapor stream could then be used to heat the down coming liquid gradually at each plate rather than as a "heat shock" on the original feed plate.
