摘要： Corrosion of ferrous metal surfaces in an aqueous system, such as a boiler system, is inhibited by adding a first component and a second component, the first component being preferably carbohydrazide, hydrazine, or a salt thereof, the second component being selected from the group consisting of certain hydroxylamine compounds or mixtures thereof, preferably N,N-diethylhydroxylamine. The weight ratio of the added first component to the added second component is between about 4:1 and about 1:4.

摘要： An improved water softening process is provided which also reduces anion content. A first stream of water is passed through an anion-exchange unit to remove undesirable anions and raise the pH. The first stream of water is then provided to reactor/clarifier water softening equipment, where it acts as a source of hydroxyl ions. Preferably a second stream of water which did not pass through an anion-exchange unit is also provided to the water softening equipment. The streams of water are combined and processed through the softening equipment, where hardness ions are precipitated out, yielding softened water with reduced anion content. The anion-exchange system utilized preferably has a counter-current continuous resin train and a counter-current continuous resin regeneration unit.

摘要： Novel hydrated-lime slurry compositions are disclosed, which include a heat-stable polymeric dispersant. The polymeric dispersant is capable to withstand temperatures in excess of 212° F. experienced by the slurry as a result of the hydrolysis of quicklime to produce hydrated lime, and accordingly can be added to the slurry composition prior to the addition of quicklime. Methods for making such slurry compositions are also disclosed.
摘要翻译： 公开了新型熟石灰浆料组合物，其包括热稳定的聚合物分散剂。 聚合物分散剂能够耐受由于生石灰水解生成熟石灰而产生的超过212°F的温度，因此可以在加入生石灰之前加入到浆料组合物中。 还公开了制备这种浆料组合物的方法。
