A process separates pure components from a product mixture produced by a one-step dimethyl ether synthesis reactor. The product mixture is scrubbed with pure dimethyl ether followed by scrubbing with aqueous methanol solvent in two absorption columns to reduce COlevel and to minimize methanol and dimethyl ether loss with the recovered unconverted synthetic gas. The pure water or aqueous methanol is mixed with the vapor stream of COseparation distillation. Dimethyl ether, methanol and water mixture are separated. A scheme for separation of methanol and water mixture minimizes the size, energy and cost of separation. The process can be cost-effective, energy-efficient, environment-friendly and readily-miniaturized.

The embodiments of the present invention disclose a composition for the colorimetric detection of water in hydrocarbon fuels and a process for the preparation thereof. The embodiments of the present invention relate to an improved method for determining the presence or absence of water in non-polar organic fluids such as petroleum oil or hydrocarbon oils by using an indicator system containing a water insoluble wetting agent and a water soluble dye which can be performed rapidly without costly instrumentation and tedious, time consuming analytical methods.

A method for significant increase in gas oil yield and energy efficiency in crude oil distillation is provided. The present invention relates to a method of separating the components of crude oil. This method utilizes the innovative and novel application of lighter fraction of crude through its superheating and its injection in the stripping section consisting of bottom to flash zone of main distillation column. Method also illustrates the innovative utilization of water in crude distillation unit to eliminate the bottom striping steam and for significant energy saving.
