Hydrogen chloride has a great affinity for water and the absorption can be easily accomplished as long as a suitable method is found to contact the gas and the water. *Note that many of the parameters can have different values for different stages in the column. .pmpro-account .content .section-article ul, Some typical VOCs are benzene, toluene, xylenes, ethylbenzene, styrene, and chlorinated hydrocarbons. Since the digestate of an anaerobic digestion has both a high temperature and a high TAN content, it is very suitable for ammonia stripping [15]. Usually, a stripping process is performed in either a packed or trayed column. Fiewin Minesweeper Bomb Scanner. Comparing treated (ammonium removed via stripping) and untreated digestate (no ammonium removal) allowed us to verify if the ammonium present in this particular digestate really exerts an inhibitory effect on the biogas production or not. After stripping the ammonium, the pH of the treated supernatant was lowered to the original pH of 7.8 by means of concentrated HCl and recombined with freshly obtained thick fraction (obtained after centrifugation of digestate).
