Abstract: Cleaning up hydrocarbon oil spills on a water surface which involves projecting open cellular particles of a highly oleophilic plastic foam such as polystyrene having a solvent affinity for petroleum substantially equivalent to that of polystyrene foam, to preferentially effect absorption of the oil and the agglomeration of the particles into lumps, mechanically recovering the lumps by screening and thereafter completely burning the oil saturated lumps to finally disposed thereof. The apparatus for carrying out the method includes a heated foaming vessel supplied with foamable plastic particles and means for projecting the particles, after they have been foamed or expanded, upon oil floating on a water surface. These means include a barrel to which the foamed particles are conveyed as well as propulsive means which disintegrate the foamed particles into relatively small particulates, which are then cast onto the oil. Preferably the oil is surrounded by the foamed particles. The apparatus can be mounted on a barge or other vessel.

Abstract: Disclosed is an improved process for the liquid phase coking of spent wood pulping liquors wherein a part of the decoked effluent is flash vaporized to supply condensate for SO2 absorption, thus eliminating the need to absorb SO2 from an oxygen-containing flue gas into sulfite ion-containing coker effluent, thereby minimizing sulfite ion oxidation and reducing the amount of makeup chemicals required to reconstitute the pulping liquor. The process is applicable to all acid sulfite pulping processes employing metallic ions such as sodium, calcium, magnesium, to ammonia-base sulfite and alkaline sulfite pulping liquors.

Abstract: A compact sewage treatment unit has at least one pressure vessel containing a heat exchanger in which a waste stream is heated to coking temperature to coke the bulk of the organic wastes except for greases which are collected in a trap tray in the upper part of the heat exchanger and discharged. Gas formed during coking is removed through a pressure relief valve. A trap tray near the bottom of the heat exchanger serves to separate the coke and the decoked effluent. The effluent passes around the tube and up the side of the pressure vessel to serve as a heat transfer medium for the coking reaction and for heating the incoming waste slurry to coking temperature. A sparger is provided above the heated zone for bringing oxygen or air in contact with the decoked effluent to oxidize any dissolved organic materials which were not coked. The unit is particularly useful for shipboard use and in apartments.
