Proposed is a moisture control module for an automobile lamp, the moisture control module includes a moisture absorption composition in the accommodating part and seals the moisture absorption composition with a breathable film and a cover, thereby reducing mounting time, space, and cost as compared with a pouch type absorbent. In addition, the moisture absorption performance continues for a long time, and when used in a closed device, which is prone to dew condensation inside according to temperature changes, especially when used in automobile lamps, the internal humidity is kept low, so that dew condensation does not occur inside, and at the same time, has the effect of preventing damage to the packaging material, etc.

A carbon dioxide adsorbent may include a double salt having a first metal salt and a second metal salt. The first metal salt may include a first metal selected from Ca, Sr, and Ba. The second metal salt may include a second metal selected from Li, Na, K, Rb, and Cs. The present disclosure also discloses a process for preparing the carbon dioxide adsorbent and a method of separating carbon dioxide using the same.

A process for treating a petroleum fraction and for efficiently absorbing an organic halogen compound from a fluid mixture of the organic halogen compound and an inorganic halogen compound derived from crude oil. Also disclosed is an improvement in absorption performance of a halogen-compound-absorbing material, thereby reducing the frequency with which the absorbing material is exchanged. The absorbing agent includes attapulgite (palygorskite) having high absorption performance with respect to organic halogen compounds. Also disclosed is an absorption column in which the aforementioned absorbing agent and a halogen-compound-absorbing agent, that includes zinc oxide, are disposed in series, thereby making it possible to raise the treatment performance with respect to a fluid that contains, in high concentrations, the organic halogen compound in addition to the inorganic halogen compound.

Dry processes, apparatus, compositions and systems are provided for reducing emissions of sulfur oxides, and sulfur dioxide in particular, and/or HCl and/or Hg in a process employing a combination of a lime-based sorbent, in particular hydrated lime and/or dolomitic hydrated lime, and a sorbent doping agent administered to achieve coverage of a three-dimensional cross section of a passage carrying SO.sub.x and/or HCl and/or Hg-containing gases with a short but effective residence time at a temperature effective to provide significant sulfur dioxide and/or HCl and/or Hg reductions with high rates of reaction and sorbent utilization. The once-through, dry process can advantageously introduce the sorbent and sorbent doping agent dry or preferably as a slurry to enable uniform treatment. Preferred sorbent doping agents include water-soluble or water-dispersible copper and/or iron compositions which can be heated to an active form in situ by the flue gases being treated.

The sealing-purger includes at least one gravity driven moving particle bed. The at least one gravity driven moving particle bed allows the plurality of heat-transferring particles or the plurality of sorbent particles to enter or leave the calcination chamber while restricting the flue gas from entering the calcination chamber and the released carbon dioxide particles from leaving the calcination chamber.

A granular sorption material including a plurality of porous granules formed by buildup agglomeration for separation, especially absorption, of harmful gases, especially of SO.sub.X and/or HCl, from offgases of thermal processes. The granules containing greater than 80% by weight, and preferably greater than 95% by weight, of Ca(OH).sub.2 and/or CaCO.sub.3 based on the dry mass.

Disclosed herein are processes for treating high-P fluid involving (1) providing a high-P containing stream; (2) chemically treating the high-P stream such that a majority of dissolved P in the stream is transformed into a solid form via sorption of P onto particles placed or precipitated within the stream; and (3) removing the solid form containing P from the chemically treated fine solids stream, such that >about 90% of the total P is removed from the high-P fluid. Also disclosed are systems for treating a high-P stream, the systems involving (1) a chemical treatment station operable to chemically treat and transform equal to or greater than about 90% of dissolved P in a high-P stream into a solid form; and (2) a liquid-solid separator station operable to remove the solid form containing P from the chemically treated high-P stream.

A slurry product is shown for treating water to both soften the water and to remove silica. The slurry is prepared by blending, in an aqueous medium, hydrated lime under the form of a slurry or of a powder with at least partly hydrated dolime, or magnesium hydroxide or magnesium oxide particles or a combination thereof under the form of a slurry or of a powder, to form an aqueous slurry where the amounts of the dolime, magnesium hydroxide or magnesium oxide particles or the combination thereof are provided such that the solid content of the slurry is up to 60% by weight of the slurry.
