2021-5-3 Solvent recovery systems, based on activated carbon adsorption, steam regenerated, are using a technology which has been proven in thousands industrial applications (mainly for mono solvent systems), treating variable volumes of gaseous effluent (2.000 ÷ 1.000.000 Nm³/h); steam is used for the regeneration of the adsorption media (activated carbon), determining this process to be ideal for the recovery of non water miscible solvents or for solvents which do not form azeotropic mixtures with water: in this case you have to apply the inert gas (nitrogen, N 2) regeneration

Surface area and pore volume measurements indicated that the adsorption capacity of the original carbon could be completely restored by thermal regeneration followed by reaction with steam. However, some activated carbon is lost implying that there would be an optimum extent of steam gasification in a cyclical adsorption-regeneration process.

2010-7-14 The steam can then be compressed, condensing the water and leaving a concentrated flow of carbon dioxide suitable for sequestration or other use -- such as a nutrient for algae growth. Because most coal-burning facilities generate steam, some of that might be bled off to achieve the separation and regeneration without a significant energy penalty.

The kinetics of the reaction between steam and thermally‐regenerated activated carbon containing DBS residue was studied at 973 to 1,062 K and atmospheric pressure. The results fit a Langmuir‐Hinshelwood rate equation originally developed for the oxidation of other types of carbon with steam. The rates of reaction were relatively high.

2012-2-29 Steam regeneration had been proven to be very effective and economical to regenerate activated carbons and hydrophobic zeolites. The regeneration of organic compounds (P-dichlorobenzene and Methyl Ethyl Ketone) from Ambersorb 563 commercial adsorbent by using steam at 160 °C had been successful for six cycles.

1995-7-1 Cost-wise, solvent regeneration of activated carbon is only a few cents per pound more expensive than steam regeneration, and less than one-tenth as expensive as thermal regeneration. Because steam regeneration is appropriate for only certain industrial applications (discussed later), the choice is usually between solvent and thermal regeneration.

1995-7-1 Solvent regeneration is one such technology. It uses solvents to dissolve adsorbed material out of the pores of the activated carbon. Then the solvent is removed by steam. This article discusses where solvent regeneration fits into the overall scheme of activated carbon applications and regeneration

2012-2-29 For the steam regeneration, the temperatures of steam (T s) were varied as 140 and 200 °C, and the flow rate of the steam (V s) was kept constant at 0.833 g s −1 by adjusting the pressure. The following Table 4 summarizes the operating conditions and the results obtained by the steam regeneration.

2006-8-23 The adsorption and steam regeneration of n-hexane, MEK, and toluene on an activated carbon fiber (ACF) were conducted for single, binary, and ternary systems and were compared with those on a granular activated carbon (GAC). An ACF bed showed not only larger adsorption capacity but also faster steam regeneration than the GAC bed.

Activated carbon is an expensive product. In most of the cases the cost of replacing the saturated carbon would be prohibitive. It should therefore be regenerated, and four methods have been developed for this purpose: Steam regeneration; This method is restricted to regenerating carbon which has only retained a few very volatile products.
