Abstract
Disclosed is the containment or controlling of waste and hazardous liquids, drilling muds and chemicals in a semi-solid or solid form for removal, transportation and disposal or otherwise handling thereby avoiding the problems and reducing the expense in removing, transporting, disposing or otherwise handling them in liquid form.
Claims28
A method of containing a liquid selected from the group consisting of waste liquids, hazardous liquids, drilling muds, and chemicals, comprising,
- absorbing the liquid in biogenetic silica in amorphous state having a porous skeletal structure,
- a major portion of the liquid being contained in void spaces of the porous skeleton,
- the biogenetic silica being present in an amount sufficient to contain the liquid in at least a semisolid mass.
A method of containing a liquid selected from the group consisting of waste liquids, hazardous liquids, drilling muds and chemicals comprising,
- containing the liquid in biogenetic silica in amorphous state having a porous skeletal structure,
- a major portion of the liquid being contained in void spaces of the porous skeleton,
- the biogenetic silica being present in an amount sufficient to contain the liquid in at least a semisolid mass, and
- holding the contained liquids in the void spaces with an additive selected from the group consisting of carbon, water soluble cement, plastic polymer, inorganic salt, paraffin, wax, solidifying agents and gels.
A method of containing mud or sludge in a pit comprising,
- adding biogenetic silica in amorphous state and having a porous skeleton to the mud or sludge in the pit effective to contain a major portion of the mud or sludge in void spaces of the porous skeleton,
- the biogenetic silica being present in an amount to contain the liquid in at least a semisolid condition.
A method of removing mud or sludge from a pit comprising,
- adding a quantity of biogenetic silica in amorphous state and having a substantially porous skeleton to the mud or sludge in the pit effective to contain a major portion of the mud or sludge in void spaces of the porous skeleton,
- the biogenetic silica being present in an amount sufficient to contain the mud or sludge in at least a semisolid condition,
- removing the mud from the pit in said condition, and
- transporting and disposing of the mud in said condition.
A method of disposing of a liquid selected from the group consisting of waste liquids, hazardous liquids, drilling muds, and chemicals comprising,
- absorbing the liquid in biogenetic silica in amorphous state having a porous skeletal structure,
- a major portion of the liquid being contained in void spaces of the porous skeleton,
- the biogenetic silica being present in an amount sufficient to contain the liquid in at least a semisolid condition, and
- placing the liquid in said condition in a disposal site.
A method of disposing of a hazardous liquid selected from the group consisting of waste liquids, hazardous liquids, drilling muds and chemicals comprising,
- containing the liquid in a container in at least a semisolid form absorbed by biogenetic silica in amorphous state with a porous skeleton,
- a major portion of the liquid being contained in void spaces of the skeletal structure,
- the biogenetic silica being present in sufficient quantity to confine the liquid in at least the semisolid form.
A method of containing a liquid spill comprising,
- adding to the liquid biogenetic silica in amorphous state with a porous skeletal structure in an amount sufficient to absorb the liquid by the biogenetic silica in at least a semisolid mass,
- a major portion of the liquid being contained in void spaces of the biogenetic silica.
A method of containing a liquid selected from the group consisting of waste liquids, hazardous liquids, drilling muds and chemicals comprising,
- absorbing the liquid with biogenetic silica in amorphous state having a porous skeletal structure,
- a major portion of the liquid being contained in void spaces of the porous structure,
- the biogenetic silica being combined with at least one additive selected from the group consisting of a water swellable polymer, loosely crosslinked copolymer of the class typified by polytertiary-butylstyrene copolymerized with divinylbenzene, polycarylonitrilebutadiene copolymer, polycarboxymethylcellulose polymers, and mixtures thereof.
