A manual mixing apparatus that contains two dual chambers with each of the chambers containing a separate and distinct chemical or liquid. Further, the apparatus has a rotatable base that allows the chemicals to be forced out of a nozzle as the base is rotated through a pair of expansion members respectively affixed to moving rear walls which move longitudinally to push a respective chemical into a front mixing tip from which the combined chemicals are discharged.

The system is provided for generating a mixed methane gas feed stream using at least one source of biogas and an alternate source of methane gas. The system includes a biogas subsystem, a control device for the methane gas from the at least one alternate source of methane gas, and a vertically-extending gas mixing vessel. A method of controlling a methane gas mass flow rate of a mixed methane gas feed stream is also disclosed. The proposed concept is particularly well adapted for situations where an uninterrupted and relatively constant input of methane gas is required to ensure an optimum operation of, for instance, a LMG production plant.

A fluid mixer of the present invention has an element (1) and a chassis (2) that accommodates the element therein and that is engaged with at least both ends of the element, the element having: a first-flow-path forming section (13) at an end of which a fluid inlet (3) is formed and in which a first flow path (4) is formed; and a body section (12) at an end of which a fluid outlet (8) is formed, in which a second flow path (5) is formed, and on an outer circumferential surface of which a plurality of communicating holes (11) are formed so as to allow the second flow path to communicate with the outside. A plurality of delay members (9) are discontinuously formed in a flow-path axial direction on at least one of an inner circumferential surface of the chassis and the outer circumferential surface of the body section, a single continuous space is formed between the inner circumferential surface of the chassis and the outer circumferential surface of the body section, the space serves as a third flow path (6), and the communicating holes serve as branch flow paths (7).

Unit for reduction of exhaust gases for an IC engine. The unit has a cylindrical housing with gas inlet and outlet openings and injector for a reducing substance. A helicoid is coaxially arranged inside the housing. A channel conveys the exhaust gases, has a substantially quadrangular cross-section, and helicoidally develops inside the unit. The helix is generated by the intersection between the inner surface of the housing and the helicoid has an inclination angle () relative to planes perpendicular to the generatrices of the cylindrical housing ranging from 0 to 30. The unit includes a coaxial stiffening and stabilization sleeve located at the center of the helicoid passing axially throughout the helicoid and axially over a length at least equal to the axial length of the helicoid. The sleeve cooperates with the inner surface of the housing and with the opposite surfaces of the helicoid to define the helicoidal channel.

A mixing device (10) containing a housing (20) that defines a mixing chamber (30), an A-component feed channel entrance opening (40), a B-component feed channel entrance opening (50), and air feed channel entrance opening (60), and an exit opening (70) where the feed channel entrance openings and exit opening provide fluid communication into and/or out of the mixing chamber, and a static mixing element (80) housed within the mixing chamber between the three entrance feed channels and the exit opening, wherein the air feed channel entrance opening having a cross sectional area that is 0.7 square mm or greater and 7.7 square mm or less.

A carbon monoxide oxidation device for oxidizing carbon monoxide contained in a hydrogen rich reformat gas includes a housing, wherein the housing incorporates an oxidation catalyst, which is adapted to oxidize the carbon monoxide of the reformat gas by an oxidizing agent to carbon dioxide, includes upstream of the catalyst at least one gas inlet for providing a gas stream of at least the reformat gas into the housing, includes downstream of the catalyst a gas outlet for exiting treated gas from the housing, and incorporates a gas stream perturbation device which is arranged upstream of the catalyst and which is adapted to provide a perturbation in the gas stream, wherein the gas stream perturbation device is designed as at least one propeller-shaped plate with a plate portion having a surface facing the gas stream and at least one blade which is connected to the plate portion and has a leading edge and an effluent edge, wherein a surface defined between leading edge and effluent edge is inclined in relation to the surface of the plate portion with a predetermined blade inclination angle, thereby defining at least one opening in the plate.
