A system and method for removing acetic acid and other short chain fatty acids described as organic acid from a rich mono-ethylene glycol (MEG) solution does so by stripping the organic acid from the rich MEG solution by contacting the solution with a gas, the gas being nitrogen or a fuel gas such as methane; and stripping the organic acid from the gas by contacting the gas with a caustic solution such as a dilute sodium hydroxide solution. The stripping steps take place in respective stripping columns. A portion of the gas exiting the gas/organic acid stripping column can be recycled to the MEG/organic acid stripping column to reduce total gas usage. A portion of the waste stream exiting the gas/organic acid stripping column can be recycled back to the gas/organic acid stripping column to reduce the amount of caustic solution used as well as the amount of waste.

The present invention relates to a method and an apparatus of preparing a reduction product of carbon dioxide by electrochemically reducing carbon dioxide.

The present invention can prepare, in an energy-efficient manner, a reduction product of high-concentration carbon dioxide with high Faraday efficiency as in a liquid reduction reaction by producing the reduction product of carbon dioxide by supplying water or an electrolytic solution to an anode region; supplying humidified carbon dioxide gas having a second temperature higher than a first temperature to a cathode region within an electrochemical cell having the first temperature so as to supply the carbon dioxide gas which has been humidified to be in a condition where the relative humidity is greater than 100%, while applying a voltage between the anode region and the cathode region so as to generate hydrogen ions (H.sup.+) in the anode region; and transporting the hydrogen ions to the cathode region through the electrolyte membrane, thereby electrochemically reducing the carbon dioxide gas.

The present invention relates to a process of synthesis of certain ionic liquids di-polymerized based Radziszewsky type reaction, whereby primary amines containing at least one terminal functional group, for example OH, aldehydes and a mineral or organic acid, react exothermically in a single step, thus resulting in an ionic liquid by condensation, then oxirane derivative molar quantities are added, by controlling the temperature and pressure a di-polymerized ionic liquid is obtained. The process of the present invention is advantageous because it provides a synthesis scheme for di-polymerized ionic liquids, primarily using short reaction times and high performance; this process can be further scaled for industrial production and it can accept alternative chemical precursors of lower cost. An example of the general synthesis scheme of ionic liquids-propoxylated di (LI's) imidazolium follows: ##STR00001## Whereby an efficiency greater than 96% of propoxylated ionic liquid is obtained, the product characterized by spectroscopic data.
