Provided an apparatus and method for carbonation treatment capable of efficiently carrying out a carbonation treatment. Provided is a carbonation treatment apparatus for subjecting a solid matter contained in a treatment object to a carbonation treatment by bringing the treatment object into contact with carbon dioxide while stirring the treatment object. The apparatus includes: a reaction vessel having a housing space in which the treatment object is housed; at least one stirrer that rotates about a vertically extending axis to stir the treatment object housed in the housing space; and the at least one stirrer being configured to move in planetary motion in the housing space when the treatment object is stirred.

A method for preparing an insulating product based on wool includes an aeration step inside a device, the device including a chamber and at least one structure capable of generating a turbulent gaseous flow, during the aeration step. A stream of carrier gas is introduced into the chamber and a wool in the form of nodules or flakes is subjected to the turbulent flow of this carrier gas with entrainment in one sense in a direction A and in the opposite sense in a direction B that is the opposite to the direction A so that within the chamber there is at least in one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.

A device may include a chamber configured to aerate a wool suitable for an insulating product; an air jet configured to introduce a turbulent gaseous flow into the chamber and entrain the wool within the chamber an entrainment of the wool in one sense in a direction A, and in a direction B that is the opposite of the direction A, such that within the chamber there is at least one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.

A system for treating exhaust gas of a vessel having at least one engine equipped with a turbocharger includes a storage tank configured to store a powder for treating the exhaust gas, and a dosing assembly fluidly coupled to the storage tank. The dosing assembly is configured to inject the powder into the exhaust gas at or adjacent the turbocharger, and includes a nozzle for injecting the powder into the exhaust gas. The nozzle includes a conduit configured to transport the powder, and a conical member mounted to a distal end of the conduit and defining a central hole in fluid communication with the conduit for guiding a first portion of the powder through the central hole. The distal end of the conduit and the conical member together define an annular gap configured to guide a second portion of the powder through the annular gap.

A dust generation apparatus is disclosed. The dust generation apparatus includes: a drum defining a drum chamber for receiving a sample; an agitation system in the drum chamber for agitating the sample to generate an aerosol of the sample in the drum chamber, the agitation system including: at least one first agitator rotatably mounted about a rotational axis extending through the drum chamber to stir the sample in the drum chamber; and a plurality of second agitators configured to tumble in the drum chamber during rotation of the at least one first agitator.
