The present invention is directed to vapor suppression of liquids through disposing a layer of surfactant onto the surfaces of liquids for surfactants having a density greater than the liquid and regardless of surface tension spreadability issues, and compositions comprising the surfactants in aerosolized form.

Base oil can be recovered from contaminated O/SBF by combining a chemical process with a mechanical process. The chemical treatment includes adding a demulsifier, an anionic surfactant, a non-ionic surfactant and/or a mutual solvent to the contaminated O/SBF in an amount effective to separate the base oil from the contaminated O/SBF fluid followed by mechanical separation of oil from water, and optionally from any solids present. The recovered base oil (i.e. conventional drilling fluid, conductive drilling fluid and constant rheology drilling fluid, etc.) may then be reformulated to make a new OBM of the same type from which the base oil was recovered, or as a fuel for engines.

A treatment process for remediating contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a liquid treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes, wherein a pH of the treatment composition is at least 13.0 and the aqueous solution contains at least one of NaOH and KOH.

The present invention generally relates to methods and compounds for reducing paraffin or wax deposition in crude oil during processing, storage, or transportation. More specifically, the method comprises contacting the crude oil with a composition in an amount effective to reduce paraffin or was deposition.

A method to make a phosphorus modified zeolite can include providing a zeolite having at least one ten member ring, making an ion-exchange, steaming the zeolite, and introducing phosphorus on the zeolite. The zeolite can be mixed with one or more binders and shaping additives, and then shaped. A metal can be introduced, and the catalyst can be washed, calcined, and steamed in an equilibration step. The steaming can be at performed at a steam severity (X) of at least about 2. The steaming can be performed at a temperature above 625 C. The catalyst can be used in alcohol dehydration, olefin cracking, MTO processes, and alkylation of aromatics by alcohols with olefins and/or alcohols.
