This invention relates to a process of recycling condensate from a hydrocarbon or alcohol synthesis, wherein the condensate comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture comprising CH and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH , and steam are separately recovered as a gaseous stream from the remaining purified water. The recovered CH -containing gaseous stream may be used in synthesis gas (CO/H ) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons.

Process for recycling and purifying condensate from a hydrocarbon or alcohol synthesis process

A profile of the emulsion pad, the oil continuous and the water continuous phases present in a coalescer, such as a crude oil dehydrater or desalter, which contains sample withdrawing means such as trycocks or a swing arm sampler for withdrawing liquid samples from a plurality of known vertical positions inside the unit, is readily obtained by withdrawing samples from a plurality of known vertical positions inside the unit and passing the samples to a receiver outside the unit which contains means for measuring an electrical property determinative of the type of phase being measured and its water content. The measured electrical property may be the energy absorption of the sample, such as RF energy absorption.

Method and apparatus for measuring phases in emulsions

This invention relates to a process of recycling condensate from a hydrocarbon or alcohol synthesis, wherein the condensate comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture comprising CH.sub.4 and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH.sub.4, and steam are separately recovered as a gaseous stream from the remaining purified water. The recovered CH.sub.4 -containing gaseous stream may be used in synthesis gas (CO/H.sub.2) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons.
