Abstract: A surfactant composition in aqueous phase includes 0.5% to 15% by weight of an alkoxylated block copolymer and 0.5% to 15% by weight of an alcohol ethoxylate. The non-ionic alkyl ethoxylate is a fast wetting agent. The block copolymer, which is characterized by a longer wetting time than the non-ionic alkyl ethoxylate, disrupts the emulsion and allows the now-coated sulfur particles to escape the existing emulsion. The composition may also include an alkyl alcohol and/or glycol ether. The alkyl alcohol augments the emulsion-breaking capabilities of the diblock copolymer by providing additional surface tension reduction to the system, as well as emulsion inhibition at the aqueous-gaseous interface. The glycol ether acts as a mutual solvent, which also augments the emulsion breaking capabilities of the diblock copolymer by providing additional surface tension reduction to the system, as well as emulsion inhibition at the aqueous-gaseous interface.

Abstract: A method of reducing the hydrogen sulfide content of an influent gas stream comprising oxygenated gas and hydrogen sulfide. An aqueous stream including an available metal chelant and the influent gas stream are contacted using an eductor. The eductor releases an eductor effluent stream including a mixture of sulfur, a first treated gas including a lower concentration of hydrogen sulfide than the influent gas stream, a first unavailable metal chelant, the available metal chelant. The eductor effluent stream is received in a common vessel wherein a plurality of activities may be performed. The plurality of activities includes generating a second treated gas by reducing a metal of the available metal chelant and producing the aqueous stream of the available metal chelant by oxidizing the first or second unavailable metal chelant using the oxygenated gas.

Abstract: A patient-centered healthcare management system with a provider dashboard interface and a patient application interface. The provider dashboard and patient application display synchronized data about patient care plans for each of a patient's diagnoses, including a next step and a risk level status for the next step. The risk level status is initially selected based on the provider's assessment of the risk that the next step will not be completed by an agreed-upon time. The risk level status is automatically elevated to a next level when the agreed-upon time passes. The provider dashboard includes a patient table that is sortable by a selected patient data value, facilitating multi-selection of patients for batch operations. The patient app receives automated reminders at preset times based on the patient's care plan, including guided self-advocacy prompts timed to occur during scheduled appointments or based on next step due dates.

Abstract: A dynamically adjustable rate sulfur recovery process continuously calculates and adjusts sour gas stream operating pressure and/or flow rate to maximize sweet gas output, thereby improving efficiency. A corresponding desulfurization system may include a fixed-sized pressure vessel, a flow control valve that controls the rate of flow of a sour gas stream into the pressure vessel, a sensor that measures sulfur concentration in the sour gas stream, a reagent tank, an oxidizer tank, and a phase separator that separates sweet gas as a gaseous phase after hydrogen sulfide in the sour gas stream in the pressure vessel is converted to elemental sulfur, sulfur species, or both by contact with reagent from the reagent tank and oxidizer from the oxidizer tank. A PLC (programmable logic controller) continuously calculates updated flow rates based on sulfur concentration measurements from the sensor to achieve maximum sweet gas production.

The weir separates the co-current contacted second fluid stream from the countercurrent contacted second fluid stream and allows the separated streams to be released from the chamber. The co-current and countercurrent contacted first fluid is released from an upper portion of the tank.

Abstract: A small-scale system for removing hydrogen sulfide and ammonia from a wastewater stream includes a sulfur recovery stage, an ammonia recovery stage, and a separation stage. Sulfur species are oxidized and converted into solid sulfur and solid sulfur species by exposure to a combination of chelated iron and oxidizer. The solid sulfur and solid sulfur species are removed by filtration to yield a sulfur-free stream to which oxidizer is added and electromagnetic radiation is inputted to break the N—H bonds of the ammonia into amine radicals. The combination of additional oxidizer and electromagnetic radiation promotes the creation of water and nitrogen gas.
