Methods and systems for purifying a caustic fluid including sulfur are provided.

A nozzle for injecting a first liquid mass into a stream of second liquid mass flowing within a pipe, comprising a first, outer, cylinder and second, inner, cylinder concentrically arranged about a nozzle axis, securing means for securing the nozzle to a wall of the pipe with the nozzle axis orthogonal to the pipe wall, the nozzle projecting into an interior of the pipe in use, duct means for receiving the first liquid mass and transporting it to the interior of the inner and outer cylinders, the inner cylinder comprising at least one hole arranged to expel liquid therethrough, and the outer cylinder comprising at least one hole arranged to expel liquid therethrough.

Dosing and mixing exhaust gas includes directing exhaust gas towards a periphery of a mixing tube that is configured to direct the exhaust gas to flow around and through the mixing tube to effectively mix and dose exhaust gas within a relatively small area. Some mixing tubes include a slotted region and a non-slotted region. Some mixing tubes include a louvered region and a non-louvered region. Some mixing tubes are offset within a mixing region of a housing.

An exhaust duct for a fossil fuel powered engine includes an exhaust gas passage, a cooling fluid passage, a mixing device for mixing cooling fluid with the hot exhaust gas and a selective catalytic reduction catalyst for removing nitrogen oxides arranged in the exhaust gas passage. The mixing device has a mixing chamber with a first wall and an opposed second wall, the first and second wall arranged upstream of the selective catalytic reduction catalyst in the exhaust gas passage and extending over the cross-sectional area of the exhaust gas passage, both walls perforated by through holes, wherein through holes of the first wall are connected with through holes of the second wall in pairs by pipes extending through the mixing chamber, the pipes perforated by at least one hole into the mixing chamber and the cooling fluid passage ending into the mixing chamber.

An exhaust line includes a housing having a wall with an opening and a baffle disposed within the opening. In certain embodiments, the exhaust line includes a divider between the wall and baffle that partially defines a mixing chamber for receiving an exhaust and a reducing agent, and partially defines a bypass chamber for receiving another portion of the exhaust. The divider defines an inlet and outlet facing respective upstream and downstream ends. The divider transfers heat from exhaust passing through the bypass chamber to the reducing agent inside the mixing chamber. In other embodiments, the baffle partially defines a first passageway substantially parallel to and offset from a center axis for delivering a portion of the exhaust to the mixing chamber, and a ramped surface partially defining a second passageway transverse to the first passageway for delivering another portion of the exhaust to the mixing chamber.

An exemplary pharmaceutical compounding system and device for mixing materials from at least two distinct material sources can include a transfer set and junction structure that has a junction body, a first inlet port located at a first portion of the junction body, a second inlet port located at a second portion of the junction body, and an outlet port located at a third portion of the junction body. The junction structure can be configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port. The junction structure can also include attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device at a location downstream of a pump system.

The present invention relates to a spacer for high pressure mixing head comprising a control cylinder flange, a head body flange, and a plurality of uprights adapted to interconnect the control cylinder flange and the head body flange. At least one of the plurality of uprights comprises at least one deformation detection sensor applied at at least one available deformation surface thereof and adapted to detect longitudinal deformations and/or transversal deformations of the at least one of the plurality of uprights. The present invention also relates to a related mixing and dosing head and to a related apparatus.

A sealed fluid transfer device and a sealed fluid transfer method includes a first container puncture apparatus, a second container puncture apparatus and a fluid transfer apparatus, wherein the fluid transfer apparatus includes a first container puncture adapter, a second container puncture adapter and a pressure supply unit; the first container puncture adapter includes a sealing element fixed seat, a guided outer casing, a pipeline fixed seat, a first fluid pipeline and a second fluid pipeline; when the sealing element fixed seat is connected with the first container puncture apparatus, a first sealing element is firstly tightly connected with a second sealing element, the first fluid pipeline and the second fluid pipeline respectively pass through the two sealing elements and then communicate with the first container; after being firstly used, the first fluid pipeline and the second fluid pipeline are always in no contact with the exterior.

A method for unsealing an opening of a laboratory sample container containing a sample is presented. The opening is sealed by a closure attached to the laboratory sample container by an adhesive. An adhesive strength of the adhesive is lowerable by treatment. The method comprises treating the adhesive such that its adhesive strength is lowered and removing the closure from the laboratory sample container.
