    摘要: A thickened acid cleaner concentrate composition comprising an inorganic acid, e.g., hydrochloric, an organic acid, e.g., oxalic, a nonionic surfactant, an anionic surfactant, a flocculating agent such as iron or aluminum ion and water is useful in cleaning vehicles such as railroad equipment. The waste water is then treated by flocculation and separation to remove suspended solids and entrained BOD prior to discharge or re-use within the plant. The flocculating agent in the composition provides a proportional pretreatment of the waste to facilitate the final treatment and separation of waste in the used composition.

    摘要: As a tall-oil-soap skimming aid, there is added to black liquor resulting from the pulping of coniferous trees a terpolymer of (a) an alpha-beta-unsaturated acid, (2) an alkylate of an alpha-beta-unsaturated acid, and (3) allyl alcohol. The acid contains 3 to 4 carbon atoms and comprises about 60 to about 88 percent by weight of the terpolymer. The alkylate comprises about 6 to 28 parts by weight of the terpolymer, being an ester of the abovementioned acids, the ester having an alkyl portion containing 1 to 18 carbon atoms. Allyl-alcohol units are present in the terpolymer to an extent of 4.5 to 20 weight percent. The terpolymer can be produced by free-radical polymerization in accordance with the customary procedures. With the use of such a copolymer, the proportion of tall oil recovered from black liquor is very substantially increased.
