  • Patent number: 10619283
    Abstract: Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.

  • Patent number: 10577563
    Abstract: Certain fatty acid amide-based surfactants such as cocamide DEA (also known as “coco(nut) diethanolamide” or “coco(nut) DEA”) when dissolved or dispersed in a cutting oil (diesel, light cycle oil, naphtha, and such other petroleum distillates) produce a petroleum distillate having significantly enhanced solvency for heavy residuals. Such solutions or dispersions are especially useful for cleaning vessels and similar equipment in refineries by circulating the solution or dispersion in the vessel, optionally with the application of heat.

  • Patent number: 10570352
    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.

  • Patent number: 10487298
    Abstract: A process for forming a descaling composition has the steps of macerating a bone meal with a dimethylamine solution, digesting the macerated bone meal with hydrochloric acid, neutralizing the digested bone meal with calcium oxide, treating the neutralized bone meal with sulfuric acid, and applying a refluxing treatment with dimethylamine and hydrazine hydrate. The process further includes removing the macerated bone meal solids from the dimethylamine solution and transferring the removed solids to an extraction tower prior to the step of digesting. The hydrochloric acid is circulated through the macerated bone meal. The treated bone meal and the sulfuric acid is filtered so as to produce a liquid phase and a solids phase. The liquid phase contains a phosphate amine. The dimethylamine and hydrazine hydrate are added to the liquid phase.

The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ?3y.
