  • Patent number: 4330409
    Abstract: Hydrolyzed wheat, corn, and potato starches are effective flocculants in destabilizing dilute as well as thick sludge suspensions. These starches are equal to, or better than, the synthetic polyacrylamide flocculants in destabilizing sludge suspensions, particularly when used in the treatment of bituminous tar sands tailings.The hydrolyzed wheat starch is especially effective when first contacted with metal salts such as salts containing calcium, aluminum and phosphate ions, and most particularly when first treated with a combination of such salt, formed in situ, and a lower aliphatic alcohol.Among the potato starch flocculants which were found to be generally better than the corn starch flocculants, those containing AlPO.sub.4 were the best. Potato starch flocculants are equally effective on oil-removed and no-oil-removed sludge suspensions.

  • Patent number: 4321153
    Abstract: Process of sulfurizing a blend of 90 to 50 and preferably 88 to 70 parts by volume of triglyceride such as lard oil and 10 to 50 and preferably 12 to 30 parts by volume of an ethylenically unsaturated hydrocarbon containing 2 to 24 carbon atoms. The sulfurization is carried out using elemental sulfur. Simultaneous sulfurization and chlorination may be effected by reacting with sulfur monochloride. Phosphosulfurization may also be carried out by addition of small amounts of a phosphorus sulfide to the sulfurized blend followed by heating at 180.degree. F. to 250.degree. F. for from 30 minutes to 10 hours to effect phosphosulfurization. The sulfurization or phosphosulfurization involves reacting at from 330.degree. F. to 445.degree. F. for 20 minutes to 10 hours followed by blowing with a gas at from 125.degree. F. to 250.degree. F. for 30 minutes to 20 hours to remove hydrogen sulfide. The simultaneous sulfurization and chlorination reaction is carried out at from 90.degree. F. to 280.degree. F.
