    摘要： The Phipps indoor air filter (PIAF) is configured for use with an indoor atmosphere that contains one or more pathogenic viruses. The PIAF is a pharmacologically and phytochemically (P&P) active structure that removes the one or more viruses from the confined indoor atmosphere. The PIAF removes the one or more viruses by: a) sequestering the one or more viruses within the PIAF; and, b) terminating the biological processes of the one or more viruses using P&P structures. The PIAF incorporates a flow chamber and a filter structure. The flow chamber contains the filter structure. The flow chamber forces or draws an air flow through the filter structure contained within the flow chamber. The filter structure physically and biochemically: a) sequesters the one or more viruses; and, b) terminates the biological processes of the one or more viruses by exposing the one or more viruses to the P&P structures.

    摘要： The removal of poisonous metalloids from crude oil is a method of removing naturally occurring arsenic (As), antimony (Sb), and bismuth (Bi) from crude oil before the crude oil is processed through a refinery. The removal of poisonous metalloids from crude oil entails forming an emulsion comprising the crude oil and an inorganic salt or mineral acid solution prepared by recirculation and agitation. The agitation of the emulsion causes arsenic (As), antimony (Sb), and bismuth (Bi) containing compounds to dissolve in the inorganic salt or mineral acid solution. The crude oil is separated from the inorganic salt or mineral acid solution by settling. The treated crude oil has a poisonous metalloid concentration of less than 1 ppm making it acceptable for oil refining operations. Optionally, any inorganic salt or mineral acid solution remaining in the crude oil after separation can be removed using a silica gel dryer.

    摘要： The novel sorbents for capturing acid and greenhouse gases converts red mud into a sorbent material that can be used to remove acid and greenhouse gases, utilizing a series of chemical reactions. The first set of reactions entail sorption of the acid/greenhouse gases and subsequent neutralization by the alkali content of the red mud. The salts generated by the neutralization reactions decompose to release the acid gases which are immediately converted to environmentally benign elemental products (N2, O2, S) by thermo-catalytic reactions. In a different set of reactions, the alkaline earth oxides (CaO and MgO) present in the sorbent capture the acid/greenhouse gases and convert them to nitrate, nitrite, carbonate and sulfite salts. The salts (beside carbonate) decompose to yield the acid gases which are converted to elemental products by thermo-catalytic reactions. The loaded sorbents are thermally regenerated to the oxide forms for re-capturing the gases.

    摘要： An integrated treatment process and apparatus is provided for removing selected contaminants from both liquid and gaseous waste streams. A multistage separation and bio-oxidation substrate is provided in a column through which the contaminants are passed. The substrate components provide absorption, adsorption, ion exchange, solubility, and bio-degradation qualities to the column to effectively separate and destroy a wide range of contaminants in industrial waste streams.
