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 takes 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.

An effective ethanol emission treatment system usable at buildings such as spirit aging warehouses which biologically removes ethanol prior to air escaping to the atmosphere is disclosed. The system can be used either with or without imparting negative pressure on the building to draw the ethanol vapors into the treatment system. The system provides efficient removal of ethanol from large volumes of air having relatively low ethanol concentrations.

A thermal oxidizer employing an oxidation mixer, an oxidation chamber, a retention chamber and a heat dissipater forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator, which is communicated to a greenhouse gas processor that extracts greenhouse gas(es) from the vaporized oxidized gases. The greenhouse gas processor may condensate the greenhouse gas(es), acid neutralize the condensation of the greenhouse gas(es), and capture the acid neutralization of the condensation of the greenhouse gas(es).

A process for treating effluent streams in a renewable transportation fuel production process is described. One or more of the sour water stream and an acid gas stream are treated directly in thermal oxidation section. The process allows the elimination or size reduction of a sour water stripper unit, waste water treatment plant, and sulfur recovery unit.

A method for removing at least one contaminant from a fluid stream by filtering the fluid stream with a filtration medium. The filtration medium includes an impregnate. The impregnate includes a surfactant such as sulfamic acid. The medium has from about 0.1 to about 25% by weight of impregnate. The method is useful for removing one or more volatile organic compounds, particularly formaldehyde, from the fluid stream. In some embodiments, the method includes removing at least two volatile organic compound contaminants from the fluid stream.

A method and apparatus for processing waste water generated during oilfield drilling operations with a mobile processing unit utilizing heat energy sourced from burning hydrocarbon fuel directly and/or capturing and using the exhaust heat energy generated by burning hydrocarbons in engines such as diesel engines in order to vaporize a dominant mass of the aqueous phase of the waste water while clarifying the heat source combustion gasses. The water vapor generated by the vaporization process may be discharged directly to the atmosphere or alternately condensed and captured for use as portable water. The residual waste water is thereby concentrated and the cost to dispose of the waste water is greatly reduced.
