    摘要： The invention relates to a process for the deinking of wastepaper stocks comprising converting the wastepaper to a pulp and contacting said pulp with an aqueous medium having a pH of about 7 or less containing a surface active deinking agent, and thereafter subjecting the resulting pulp-containing medium to one or more wash and/or flotation steps which is carried out at a pH of about 7 or less to remove suspended ink therefrom and to condition said pulp-containing medium for subsequent addition to a paper machine.

    摘要： An improved process for recovering oil by flowing a mixture of steam and steam foam surfactant into an oil-containing subterranean reservoir, the improvement provided by using surfactants enriched in olefin disulfonate. The surfactants may be used in either a steam drive or a steam soak process. Disulfonate-enriched steam foam surfactants and mixtures are also described.

    摘要： Methods of preparing viscous aqueous polymer solutions having improved viscosity and stability properties for use in the treatment of subterranean hydrocarbon-containing formations and in enhanced oil recovery processes are provided. Methods and systems for enhancing the recovery of oil from subterranean oil-containing formations are also provided. The viscous aqueous polymer solutions of the invention are prepared by polymerizing one or more water soluble polymerizable vinyl monomers in a substantially oxygen-free aqueous solvent and then further diluting the resultant concentrated solution in additional solvent. Such viscous aqueous polymer solutions have improved viscosity properties and increased compatibility with oil well treating fluid additives, especially clay stabilizers.
