A system and method for a constituent rendering of biomass and other carbon-based materials is provided. The system can be configured for receiving a feedstock material to be rendered into its constituent components, grinding the feedstock to a desired size and/or consistency, and placing the feedstock in contact with a hot mix heat transfer medium within a pressure chamber. Pyrolysis of the feedstock can lead to a breakdown of the feedstock into constituent components that can then be collected.

Provided is a cardboard conversion line including a wet cyclone dust collector for removing dust laden air from the conversion line. The wet cyclone dust collector has a swirl chamber in which air containing particles swirls in a rotational direction and a plurality of circumferentially spaced nozzles located within the swirl chamber to direct a spray of fluid within the swirl chamber in the rotational direction to wet the air containing particles, and the wetted particles are separated from the air in the swirl chamber. In this way, a system may be provided to clean high volumes of air containing particles without having to provide an explosion vent and without having to provide additional fans, motors, and compressed air.

A scrubber wastewater treatment method, according to one possible embodiment, includes obtaining a measurement of a turbidity or of a suspended substance concentration of scrubber wastewater and, upon determining that measurement of turbidity or suspended substance concentration is within a certain range, performing treatment. A scrubber wastewater treatment device, according to one possible embodiment, includes a magnetic powder adding device controllable to add a magnetic powder to be added to scrubber wastewater having been generated by treating combustion exhaust gas in a scrubber, and a controller configured to control an amount of the magnetic powder added by the magnetic powder adding device in accordance with a measurement value obtained by a sensor.

A promoted activated carbon sorbent is described that is highly effective for the removal of mercury from flue gas streams. The sorbent comprises a new modified carbon form containing reactive forms of halogen and halides. Optional components may be added to increase reactivity and mercury capacity. These may be added directly with the sorbent, or to the flue gas to enhance sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The sorbent can be regenerated and reused. Sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active sorbent into the mercury contaminated gas stream are described.

An engine air intake dust removal system and method, comprising an air intake dust removal system inlet (1011), an air intake dust removal system outlet and an air intake electric field device (1014). The air intake dust removal system (101) and method can effectively remove particulate matters from air trying to enter the engine, and make the air entering the engine cleaner.

An exhaust gas treatment system, comprising an ozone purification system. The ozone purification system comprises an ozone amount control apparatus (209), used to control an amount of ozone so as to effectively oxidize gas components to be treated in exhaust gas, the ozone amount control apparatus (209) comprising a control unit (2091). By means of the present exhaust gas treatment system, particulate matter can be effectively removed from exhaust gas, and the system features a better exhaust gas purification treatment effect.

The facility (1A) includes at least two treatment devices (2) each with an exchange chamber (20) intended to contain a liquid bath in the bottom part and at least one injection line (21). An aeraulic means (4), creates by suction or by blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) originating from outside the exchange chambers (2) and passes through the discharge opening of the injection line (21) by being introduced into the liquid bath contained in the bottom part of the exchange chamber (20), below the surface (S) of said liquid bath. The exchange chambers (20) communicate hydraulically with one another so that when the aeraulic means (4) are shut down, each exchange chamber (20) is suitable for containing or contains, in the bottom part, an initial volume (V.sub.initial) of liquid, with an initial liquid level (H.sub.initial) that is identical in all the exchange chambers (2).

An integrated system for the conversion of biomass to renewable natural gas and then to methanol and other value-added products is provided. The integrated system includes a compressor that receives biomass gases from a biomass source and a series of purification stations that produce purified gas from the biomass gases. Characteristically, the purified gas has an enhanced amount of methane. A gas-to-liquids plant converts the purified gas to a product blend that includes methanol.

Provided herein are integrated biomass combustion-carbonation gas conditioning systems to directly sequester carbon dioxide from biomass-derived CO.sub.2-containing flue gas. The CO.sub.2 is sequestered by mineral carbonation in concrete materials within a carbonation reactor. The mineral carbonation processes sequester CO.sub.2 in concrete materials, aqueous slurries, or aggregates without any additional carbon enrichment process. Contacting a CO.sub.2-containing gas stream from a biomass combustion apparatus with concrete, aggregate, or alkaline solutions, causes a carbonation reaction in which carbonation products such as calcium carbonate (CaCO.sub.3) and alumina silica gel are formed. The carbonation reactions set forth herein are useful for strengthening concrete and concrete components. Certain processes herein condition the biomass-derived flue gas. The conditioning includes condensing the gas to remove acidic gas, and to remove particulates and water. The conditioning includes adjusting the temperature, relative humidity, and gas flow rate of the biomass-derived flue gas without any carbon capture step before entering the carbonation reactor. The permanent storage of CO.sub.2 in concrete materials reduces carbon emissions from biomass combustion systems. The process does so, in certain embodiments, at low temperatures, ambient pressure, and even under dilute CO.sub.2 concentrations in CO.sub.2-containing flue gas streams. For example, the CO.sub.2 concentration in a CO.sub.2-containing flue gas stream from a biomass combustion system may be lower than 20 volume percent (vol %) and be used to produce low-carbon concrete materials.
