The invention relates to an injection device () for atomizing a liquid into droplets using a gas, comprising a hollow tubular body () having a longitudinal direction (X). An inner wall () defines a first region, referred to as contact region (Z), and a second region (Z). The body includes: &#x2014;at least two inlet ports () for injecting liquid and an inlet port for injecting gas, all of said ports extending to the first region (Z); &#x2014;at least one outlet port (), located downstream of the first and second regions, for discharging the atomized liquid. The body () has an inner cross-section that varies continuously or constantly over the entire length thereof. Between regions (Z) and (Z), the inner wall () includes at least one baffle () which is shaped such that in each plane running perpendicularly to the longitudinal direction of the body containing said baffle, the baffle reduces an inner cross-section of the body over the entire periphery of the inner wall ().

The invention relates to an injection device () for atomizing a liquid into droplets using a gas, comprising a hollow tubular body () having a longitudinal direction (X). An inner wall () defines a first region, referred to as contact region (Z), and a second region (Z). The body () has an inner cross-section that varies continuously or constantly over the entire length thereof except at the junction between the first and second regions, where the inner wall () of the body includes at least one cavity () which increases the size of the inner cross-section of the body, said at least one cavity extending over a predefined length in the longitudinal direction.

Feedstock injection device of an FCC unit, having a locally larger cross-section

The invention relates to an enclosure () of a fluid catalytic cracking unit in which an inner space is defined by a side wall () having a longitudinal axis extending substantially in the direction of gravity, said enclosure being provided with a plurality of mechanical separation cyclones () located inside the inner space. The enclosure () comprises a supporting device () attached only to the cyclones () by: an annular peripheral support element () extending along the side wall () in a plane perpendicular to the longitudinal axis (X), separated from the side wall by a predetermined clearance; and a plurality of beams () extending in the same plane as the peripheral support element (), the beams being rigidly connected to the peripheral support element and to at least one mechanical separation cyclone by one end or by an attachment part distant from the ends thereof.

The invention relates to an injection device () configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body () of longitudinal direction (X). An internal wall () defines a first zone referred to as a contact zone (Z) and a second zone (Z). The device () is notably provided with an atomizing element () mounted on an opening () of the body situated facing an opening () for injecting a liquid, comprising a tubular pipe () for conveying gas into the first zone (Z), and a target () situated at the centre of the pipe. The body has an internal cross-section that varies continuously or is constant over its entire length (for example the shape of a simple cylinder) and of which the internal wall is provided, between the zones (Z) (Z), with at least one chicane () projecting from the internal wall towards the inside of the body.

The invention relates to an injection device () configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body () of longitudinal direction (X). An internal wall () defines a first zone referred to as a contact zone (Z) and a second zone (Z). The body has: The internal wall () of the body is provided, between the zones (Z) (Z), with at least one chicane () configured so that, in each plane perpendicular to the longitudinal direction of the body containing the said chicane, this chicane extends over just part of the periphery of the internal wall ().

FCC unit charge injection device with limited pressure drop

The invention relates to a metal element () for anchoring an anti-erosion coating that is intended to be fastened alone in an isolated manner to a metal wall or assembled with other identical anchoring elements. The anchoring element () has an edge () for fastening to said metal wall and an anchoring body firmly attached to the fastening edge () and having an upper edge () that is away from the fastening edge and intended to be covered by a composite material of concrete type. A section of this upper edge (), which is not intended to be juxtaposed and assembled with an upper edge of an identical anchoring element, is provided with a delimiting tab () in order to delimit a height of composite material that must cover the upper edge () of said anchoring element, said delimiting tab () having a delimiting edge () that is a predetermined distance away from a plane defined by the upper edge () of the anchoring element.
