Abstract:

An electrolytic cell and system used for making nitrogen trifluoride consisting of a computer and an electrolytic cell having a body, an electrolyte, at least one anode chamber that produces an anode product gas, at least one cathode chamber, and one or more fluorine adjustment means to maintain fluorine or hydrogen in the anode product gas within a target amount by adjusting the concentration of fluorine in said anode product gas, and the process that controls the system.

Appl. No.:

8/079063

Inventors:

Edward J. Cialkowski - Houston TX

Assignee:

The M. W. Kellogg Company - Houston TX

International Classification:

B01D 314

US Classification:

203 18

Abstract:

A methanol refining column and method using an intermediate reboiler. Use of the intermediate reboiler reduces methanol production energy requirements. A side stream at or near a fusel oil takeoff point is heated in an intermediate reboiler by a low temperature heating medium (relative to a bottoms reboiler) and returned to the column at or near the fusel oil take-off tray. The take-off tray is operated at 85. degree. -110. degree. C. , and 70-90 percent of the reboiler duty is supplied through the intermediate reboiler. The remaining heat load is supplied by a bottoms steam reboiler.

US Classification:

252158

Abstract:

A method for recovering volatile components from reformer effluent condensate and fusel oil in a methanol plant is disclosed. The fusel oil is stripped with steam to produce an overhead vapor stream of steam and stripped organic components which is recycled to the feed to the reformer. Also disclosed are a methanol plant with a fusel oil stripper; and a unitized stripper column for treating fusel oil and process condensate wherein steam containing volatile gases stripped from the process condensate is used to strip the fusel oil. The present invention improves yield and reduces or eliminates liquid fusel oil waste by recycling volatile organic components contained in the fusel oil to the feed of the reformer.
