Each of the scallop, the center pipe, and the outer basket has openings formed therein. wherein the sizes or the shapes of the openings vary along the length or the width of the reactor components such that the openings define a pattern in configured to manipulate and optimize the distribution of flow of feedstock out of the components and through the reactor to maximize the efficiency of the catalyst reaction thereof.

A filtration apparatus for filtering a fluid stream includes a vessel housing. At least one cartridge assembly is arranged within the vessel housing. The cartridge assembly includes filtration material arranged between at least one inlet and at least one outlet. The filtration material treats the fluid stream to form a filtered fluid stream. In use, the fluid stream is received a feed port of the vessel housing, flows through the filtration material in the cartridge assembly between the inlet and the outlet, and the filtered fluid stream is discharged from a discharge port of the vessel housing. The filtration apparatus can be used to remove siloxanes from the fluid stream.

A multi-compartment bed radial flow adsorber capable of realizing large telescopic deformation mainly comprises an adsorber body, the adsorber body consists of an upper seal head, a barrel, a lower seal head and a pressed shell connected with an upper connecting pipe and a lower connecting pipe, the upper seal head and the lower seal head of the shell are each provided with an upper gas inlet and outlet pipe and a lower gas inlet and outlet pipe, a supporting seat is arranged at the bottom in the shell, an adsorption barrel is arranged above the supporting seat and consists of a plurality of concentric barrels with different diameters, a plurality of annular spaces are formed by the concentric barrels with different diameters, different types of adsorbents can be filled in the annular spaces, and the adsorption barrel is composed of a pore plate or a grid.

An air pollution remediation system is provided. The systemic apparatus includes a tubular column having a plurality of spaced apart vents along its outer surface. Each vent has adjustable louvers for controlling the airflow therethrough. An airflow conduit extends along the longitudinal length of the column with porous layers and a mass of absorbent disposed between the airflow conduit and the plurality of vents. A fan fluidly coupled to the airflow conduit urges ambient air into the airflow conduit and through the porous layers and the mass of absorbent and out of the vents in a selectively controlled manner by way of the adjustable louvers. A prefilter may be disposed upstream of the fan. A network of the systemic apparatus can be arranged to provide, in a selective enabled manner through the adjustable louvers, a contiguous looping canopy of purified air over large open spaces.

A sorption device for filtering evaporation emissions from a fuel tank, includes a vessel with a first opening connected to an air removal path of the fuel tank and a second opening opening to atmosphere, a middle annular space between a radial outer circumferential boundary of the middle annular space and a radial inner circumferential boundary thereof radially inwardly spaced apart from the outer boundary, a first annular space formed between a radial inner surface of a fluid tight circumferential outer shell of the vessel, the radial outer boundary being radially inwardly spaced from the inner surface, a sorbent material arranged in the middle annular space, and evaporation emissions from the fuel tank are guided through the first opening into the first annular space, through the sorbent material into a central space of the vessel in the radial direction, and through the second opening to atmosphere or another sorption device.

A method and a device intended to purify pollutants from an exhaust gas flow of an internal combustion engine operated with sulphur containing fuel, in particular of a ship internal combustion engine operated with heavy fuel oil, are provided. Exhaust gas flow is in contact with a solid adsorption agent of the adsorber in a first step and binding in particular acid pollutants, which comprise sulphur dioxide and sulphur trioxide. The exhaust gas flow is then guided by a second stage of the adsorber realising fine purification of the exhaust gas flow. The adsorption agent of the second stage is used in the first stage as an adsorption agent.

A filtering device is provided for filtering pollutants from a gas stream. The device includes a cartridge comprising an inner perforated passage, an outer perforated jacket, one or more non-perforated ends and a sorbent bed contained between the inner passage and the outer jacket; and a outer shell containing the cartridge and having a first port in fluid communication with the inner perforated passage and a second port in fluid communication with the outer perforated jacket. A flowpath of the gas stream into any one of the first port or the second port, through the sorbent bed and out of the other of the first port or the second port is a bidirectional flowpath. A method is further provided for filtering pollutants from a gas stream. The method includes the steps of allowing the gas stream to flow into a filtering device in a first direction, the device comprising a cartridge having a sorbent bed contained therein; directing the gas stream to bend in a second direction differing from the first direction as it enters the sorbent bed; and allowing the gas stream to pass through the sorbent bed and to exit the device.

A moisture extraction component including: an inlet; an outlet opposite the inlet; an inner surface defining a main flow channel, the main flow channel fluidly connecting the inlet to the outlet; a path on the inner surface configured to direct moisture flow, the path being defined by differences in hydrophobicity on the inner surface using at least one of a hydrophobic surface and a hydrophilic surface.
