A method for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO. The COis removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure COand to regenerate the sorbent for repeated use. Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently. The above method provides purified carbon dioxide for further use in agriculture and chemical processes, or for permanent sequestration. 136-. (canceled)37.

Though similar in molecular structure, the presence of sulfur instead of oxygen elicits many differences. Mercaptans are more odorous, with a stronger and repulsive smell in mercaptans with lower molecular weights. Mercaptans are responsible for a number of wine faults caused by unintended reactions between sulfur and yeast and for the “skunky” odor of beer after it has been exposed to light. Mercaptans are often used as odorants to assist in the detection of natural gas ( ...
