Alkaline compositions useful to form aqueous paint stripping solutions are disclosed which comprise mixtures of an alkali metal hydroxide, a polyoxyalkylene polyamine accelerator and, optionally, a glycol or glycol ether accelerator.

Polyalkylene polyamine-glycol accelerators for paint removal compositions

Aqueous alkaline polyamine paint stripping compositions

Slag buildup in high-temperature areas of a furnace system is minimized by adding to the molten ash particles carried by the flue gas a conditioner which is taken up by those molten particles and produces a nucleating effect when those particles cool, causing them to solidify more rapidly, thereby preventing deposit formation or resulting in considerably more friable deposits.

Method of reducing high temperature slagging in furnaces

The collection characteristics of particles entrained in a particle-laden gas for separation by the commonly used methods for removing particles from a gas stream are improved by injecting into the gas stream a conditioning agent comprising diammonium phosphate and urea. The conditioning agent can be added to the gas stream either at low temperatures or at high temperatures, in both cases giving rise to significant improvements in emission characteristics. The additive of the present invention has a very significant advantage over prior art additives of substantially equal emission improvement characteristics of greatly reducing or substantially eliminating buildup of hard-to-remove deposits.
