A polymer aerogel monolith comprising a polymer aerogel having a nitrogen content of greater than seven weight percent impregnated into a mesh. A method of manufacturing an amine-containing polymer aerogel monolith, includes combining a vinyl-containing cross-linking monomer, a vinyl-containing functional monomer, an organic solvent, and a radical initiator into a liquid mixture, applying the liquid mixture to a mesh fabric to produce a monomer-impregnated mesh, heating the monomer-impregnated mesh to produce a polymer aerogel monolith, washing the polymer aerogel monolith with acid to produce an ammonium-containing polymer aerogel monolith, and applying a base to neutralize the ammonium-containing polymer aerogel monolith to produce an amine-containing polymer aerogel monolith. A direct air capture module has one or more amine-containing polymer aerogel monoliths, one or more air flow channels positioned to pass air through the monolith A monolith comprising a poly(alkylamine-co-divinylbenzene) impregnated mesh.

A method includes forming a carbon aerogel on a substrate to produce a highly adsorptive structure. The carbon aerogel is characterized by having physical characteristics of in-situ formation on the substrate.

A Vapor Recovery Unit (VRU) includes a VRU heat exchanger and a sorbent material for the recovery of hydrocarbon vapors from the ullage of tanks. The VRU heat exchanger and sorbent material are useful in conjunction with a thermal transfer fluid to control the temperatures of the sorbent material during endothermic and exothermic reactions that occur when hydrocarbon vapors are adsorbed and desorbed, which increases performance and reduces the amount of sorbent material required to recover hydrocarbon vapors.

Sorbent material sheets are wound around a center core of material that includes additional sorbent. This configuration further increases the packaging efficiency and performance of the sorbent material sheets as part of an overall housing or apparatus. In some embodiments, the sorbent material sheets are arranged in a stacked configuration. Configurations of the sorbent material sheets as part of a canister are also described.

A method of manufacturing an erosion, sediment and pollution control product comprises heat treating a rice hull filler material for sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material; filling a tubular containment member with the rice hull filler material in a manner allowing fluid to flow through the containment member and the rice hull filler material. The containment member is a geotextile which may include cellulose based threads treated to be hydrophobic.

A sorption filter element for a sorption filter device includes at least two sorption bodies with at least one sorbent, the at least two sorption bodies being arranged in a V-shape and enclosing an intermediate space that is open at a head side thereof, and an outer sealing element running around an outer circumference of the head side. The sorption filter element further includes an inner sealing surface arranged at the head side and running around a circumference delimiting the intermediate space at the head side, the inner sealing surface being axially set back relative to the outer sealing element and being arranged within the intermediate space.

A sorption filter device includes a sorption filter element including at least two sorption bodies with at least one sorbent, the at least two sorption bodies being arranged in a V-shape and enclosing an intermediate space that is open at a head side thereof, an outer sealing element running around an outer circumference of the head side, and an inner sealing surface arranged at the head side and running around a circumference delimiting the intermediate space at the head side.

A method of assessing a membrane, including calculating fluid dynamic characteristics of at least one of a membrane and a material to be passed through the membrane, where the material comprises particles; obtaining characteristic of at least one force acting on the particles of the material to be passed through the membrane due to the interaction between the particles and the membrane, the at least one force being an intermolecular force; combining the calculated fluid dynamic characteristic and the obtained characteristics to assess the flow of the material through the membrane; and optimizing at least one characteristics of the membrane in relation to the material. The membrane includes a plurality of rows and a plurality of teardrop structures arranged in the plurality of rows. The teardrop structures in each row are arranged at substantially the same angle with respect to an anticipated direction of flow through the membrane.
