    Abstract: A polymer-containing sheet material is manufactured by embedding a polymerization solution, containing a polymerizable monomer throughout at least a portion of the thickness of a polymerization-initiating sheet material, for intimate contact with the polymerization catalyst or polymerization initiator (20) to initiate polymerization of the monomer. Manufacture of a polymer-containing sheet material comprises contacting a liquid-sorbent sheet material, or material used to make the liquid-sorbent sheet material, with a polymerization initiator or polymerization catalyst in an amount to initiate polymerization of a later added polymerizable monomer, to produce a polymerization-initiating sheet material; embedding a polymerization solution, containing a polymerizable monomer throughout at least a portion of the thickness of the polymerization-initiating sheet material, for intimate contact with the polymerization catalyst or polymerization initiator to initiate polymerization of the monomer; and subjecting the sheet material to conditions to polymerize the monomer, to form a polymer embedded in the sheet material, thus securing the polymer to the sheet material.

    Abstract: Water-absorbent sheet material is manufactured by contacting a liquid-sorbent polymerization initiating substrate with polymerization catalyst and/or polymerization initiator, embedding the polymerization initiating sheet material with clay-containing slurry, and heating the embedded sheet material to polymerize the monomer and vaporize, to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. Manufacture of water-absorbent sheet material comprises contacting a liquid-sorbent polymerization initiating substrate with a polymerization catalyst and/or a polymerization initiator to form a polymerization-initiating sheet material for a subsequently embedded monomer; embedding the polymerization initiating sheet material with a clay-containing slurry comprising water, clay, and polymerizable monomer to form a water-sorbent polymer; and heating the embedded sheet material to polymerize the monomer and vaporize at least a portion of the slurry water to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. The slurry comprises less than 50% water. The weight ratio of monomer to clay is 1:19, throughout a portion of the thickness of the polymerization-initiating sheet material for intimate contact with the polymerization catalyst or polymerization initiator to initiate polymerization of the monomer.

    Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic media will become "spent" and at a certain "spent level", the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the "spent" organophilic media should be replaced with fresh media or the spent media regenerated.
