    Abstract: Methods for making efficient use of steam in a steam-assisted gravity drainage (SAGD) process for recovering heavy oils from tar sands and similar petroleum deposits are disclosed. The methods utilize a surfactant to generate steam foam in ways that maximize efficient use of steam. In some aspects, steam foam is used in water layers or gas caps that reside above steam chambers 4 to prevent loss of steam 6 from the steam chamber 4. The predominant use of relatively dry steam in SAGD processes makes it challenging to find ways to introduce surfactants 5 and generate steam foam 8. However, decreasing the mobility of the steam 6 by converting at least some of it to foam 8 allows the wellbore and steam chambers 4 above the injection site to be more fully developed, provides for more effective heat transfer to the heavy oil and rock, improves production, and allows recovery of the heavy oil with a minimum amount of steam usage.

    Abstract: A cold-water cleaning method and laundry detergents useful therein are disclosed. The method comprises laundering one or more textile articles in water having a temperature less than or equal to 30°C in the presence of a detergent comprising a C 4 -C 14 dialkyl sulfosuccinate or sulfomethylsuccinate, a linear alkylbenzene sulfonate, and an optional nonionic surfactant. We surprisingly found that combinations of C 4 -C 14 dialkyl sulfosuccinates or sulfomethylsuccinate and linear alkylbenzene sulfonates provide outstanding performance in removing greasy stains such as beef tallow from soiled articles even at wash temperatures of 30°C or less.

    Abstract: Laundry detergents useful for cold-water cleaning and a cold-water cleaning method are disclosed. The detergents comprise: (a) an a-sulfonated fatty ester surfactant comprising a compound having the formula: R 1 -CH(SO 3 M)-CO-OR 2 wherein M is hydrogen, an alkali metal, an alkaline earth metal, ammonium, and amine salt, or a mixture thereof; R 1 is an unsubstituted or hydroxy-substituted, saturated or unsaturated, linear or branched C 6 -C 16 alkyl group; and R 2 is a saturated or unsaturated linear or branched C 8 to C 12 alkyl group; and (b) an anionic surfactant, a nonionic surfactant, or a combination thereof. Surprisingly, α-sulfonated fatty ester surfactants derived from a C 8 to C 12 alcohol provide outstanding performance in removing greasy stains such as bacon grease, cooked beef fat, or beef tallow from soiled articles even at wash temperatures at or below 30°C. Detergents formulated with the surfactants outperform control cold-water detergents by a wide margin, including detergents comprising α-sulfonated fatty esters made from lower alcohols, such as methyl, butyl, or hexyl esters of α-sulfonated fatty acids.

    Abstract: Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene- bridged surfactant. The mid-chain headgroup surfactants have a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the C14-C30 alkyl chain. The alkylene-bridged surfactants comprise a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid- chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.
