20080245233 | Method for Inhibiting Fouling in Basic Washing Systems - Fouling in basic washing systems such as caustic scrubbers can be prevented or at least mitigated by treating the liquid washing phase used in a caustic scrubber with an additive having at least one compound selected from the group consisting of oxalyl dihydrazide, a disulfite salt, isopropyl hydroxylamine, chlorobenzhydrazide, aminobenzhydrazide, a thiosulfate salt, 4,4-dimethyl oxazolidine, a hydrosulfite salt, and mixtures thereof. | 10-09-2008 |
20090061234 | Method for Inhibiting Corrosion of Metal in Distillation Units Caused by Organic Acids - Corrosion may be inhibited in a separation unit by treating at least one surface of the separation unit with a corrosion inhibitor. The corrosion inhibitors are those having a general formula: | 03-05-2009 |
20090211947 | Method for Reducing Fouling in Furnaces - Heat exchanger fouling in organic chemical production processes may be reduced using an antifoulant additive. The antifoulant additive may have one component selected from the group consisting of an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; or it may have two components selected from the group consisting of a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer, wherein at least one of the two components in not an overbase. An additive having three components: a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; is also within the scope of the disclosure. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 08-27-2009 |
20130277606 | METHOD FOR INHIBITING FOULING IN VAPOR TRANSPORT SYSTEM - Elimination and/or mitigation of fouling in a vapor transport systems, such as vent lines and scrubber feed lines may be accomplished using an antifouling additive. The method for employing the antifouling additive includes introducing into the vapor transport system an additive including a polar solvent and corrosion inhibitor wherein: the vapor transport system is substantially water free; the vapor transport system is used to transport acidic materials; the additive is a liquid at vapor transport system operating conditions; and the additive is stable at the vapor transport system operating conditions. | 10-24-2013 |
20140121399 | Quinone Compounds for Inhibiting Monomer Polymerization - The polymerization of monomers may be at least partially reduced or inhibited by introducing an effective amount of an additive. The additive may be or include a first compound: | 05-01-2014 |
20140241940 | METHOD FOR INHIBITING FOULING IN VAPOR TRANSPORT SYSTEM - Elimination and/or mitigation of fouling in a vapor transport systems, such as vent lines and scrubber feed lines may be accomplished using an antifouling additive. The method for employing the antifouling additive includes introducing into the vapor transport system an additive including a polar solvent and corrosion inhibitor wherein: the vapor transport system is substantially water free; the vapor transport system is used to transport acidic materials; the additive is a liquid at vapor transport system operating conditions; and the additive is stable at the vapor transport system operating conditions. | 08-28-2014 |
20140243564 | METHOD FOR INHIBITING FOULING IN BASIC WASHING SYSTEMS - Fouling in basic washing systems such as caustic scrubbers can be prevented or at least mitigated by treating the liquid washing phase used in a caustic scrubber with an additive having at least one compound selected from the group consisting of oxalyl dihydrazide, a disulfite salt, isopropyl hydroxylamine, chlorobenzhydrazide, aminobenzhydrazide, a thiosulfate salt, 4,4-dimethyl oxazolidine, a hydrosulfite salt, and mixtures thereof, particularly in the case where the liquid washing phase includes components that may undergo an aldol condensation, the products of which may cause fouling solids and/or sludges. | 08-28-2014 |
20140330053 | Hydroquinone Compounds for Inhibiting Monomer Polymerization - The polymerization of monomers may be at least partially reduced or inhibited by introducing an effective amount of an additive. The additive may be or include at least one hydroquinone, such as but not limited to, 2,6-di-tert-butyl hydroquinone, 2,5 di-tert-butyl hydroquinone, 3,5 di-tert-butyl hydroquinone, 3,5 di-methyl hydroquinone, 3,6 di-tert-butyl hydroquinone, and combinations thereof. The polymerizable monomers may be or include, but are not limited to styrene, butadiene, isoprene, acrylic acid, acrylonitrile, vinyl acetate, and combinations thereof. | 11-06-2014 |
20150072436 | Methods of Measuring Dissolved Oxygen in a Hydrocarbon Stream - At least one probe may be introduced into a hydrocarbon stream for detecting dissolved oxygen species therein. The hydrocarbon stream may have or include at least one probing additive where the probing additive(s) may be added to the hydrocarbon stream, coated onto the probe(s), or both. The probe(s) may detect at least one luminescent measurement from the hydrocarbon stream, and the luminescent measurement(s) may determine whether dissolved oxygen species are present within the hydrocarbon stream. | 03-12-2015 |
