Abstract: A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor.

Abstract: A method of digesting lignocellulosic material includes the steps of providing the lignocellulosic material and a caustic composition having a pH of at least about 10. The caustic composition includes water, an alkaline- or alkaline earth- metal hydroxide, and up to about 1 percent by weight based on a total weight of the composition of a branched digestion additive. The branched digestion additive has the structure: wherein A is at least one alkyleneoxy group and each alkyleneoxy group has from 2 to 4 carbon atoms, n is 0 or 1, B is a branched aliphatic hydrocarbon group having from 8 to 15 carbon atoms, X is H or B-0-(A)m, and each m is independently an average value from 3 to 30, and wherein the caustic composition has a Draves Wetting Time of less than 100 seconds as determined using ASTM D2281.
