摘要： 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.

摘要： 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.

摘要： An oxidation-reduction desulfurization system includes a reactor vessel with sour gas inlet at the bottom and a gas outlet at the top. A primary stage phase separator includes a vertically-oriented pipe with an inlet located inside the reactor vessel. The ratio of the reactor vessel diameter to the pipe inlet diameter is in a range of 2:1 to 5:1. Surface foam and non-gaseous multi-phase mixture including emulsion flow into a partially gas-filled upper section of the vertically-oriented pipe and freefall to a lower level, thereby facilitating mechanical breaking of the foam and the emulsion. A secondary stage phase separator connected to the gas outlet separates non-gaseous surge from sweet gas. Valves and a controller automatically maintain target levels of the non-gaseous multi-phase mixture and non-gaseous surge.

摘要： A filter silencer with quick disconnect lid has a cylindrical hollow casing, an inlet, a filter within the casing, a spring loaded seal plate beneath the filter, a flange opposite the inlet, and a lid turning to connect to the flange. The inlet admits blower air into the casing generally beneath the spring loaded seal and the air enters the sides of the filter. The air travels upwards through the filter and exits through the lid. Wear pads beneath a locking ring engage the tapered ears upon the lid. The lid has an outlet through which filtered air discharges. The lid has ports for monitoring differential pressure and air temperature while the casing has a port for a pressure relief valve.

摘要： A pipe coupler interconnects pipes and fittings and sections of pipe end to end for transferring bulk dry and fluid materials. The coupler connects various pipe ends, grooved, smooth, and ground, together. The coupler also connects various fittings such as tees and valves to pipe ends. Two arms clamp upon the two pieces of a gasket to seal the connection of pipes and fittings within the coupler. A plurality of ridges upon both surfaces of the piece grasp and seal the end of a pipe. The gasket removes any gaps in the connection that would have trapped material and contaminated later loads of material.
