COLLECTING A GASEOUS POLLUTANT FROM AIR
An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

NEUTRALIZING ABSORBENT FOR DECONTAMINATING LEAKED CHEMICAL SUBSTANCE, METHOD OF PREPARING THE SAME, AND NEUTRALIZER FILLED WITH THE SAME
The present invention relates to a neutralizing absorbent for decontaminating a leaked chemical substance, a method of preparing the same, and a neutralizer filled with the same. The neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention includes an inorganic adsorbent, which is commonly usable in neutralizing absorption of acidic, basic, and/or organic chemical substances, at 40 to 60 wt %, a thickener at 20 to 30 wt %, a surfactant at 20 to 30 wt %, and a color change indicator, and is formulated in a solid state. The neutralizing absorbent is effective in promptly and safely taking an initial action regardless of the type, nature, and characteristics of acidic, basic, and/or organic chemical substances leaked in the leakage accident of the chemical substance, and accordingly, is useful in preventing secondary accidents. Also, when the neutralizing absorbent is used, there are no concerns about the spread of contamination due to water generated by an acid-base reaction, concerns about the additional occurrence of secondary contamination due to a decontaminating agent can be minimized by using a non-toxic chemical absorbent, and a decontamination process can be visually checked in real time regardless of the type, nature, and characteristics of the leaked chemical substance. Furthermore, when a neutralizer filled with the neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention is used, the leaked chemical substance can be more safely and effectively decontaminated during an initial action.
