The technology involves the sorption and recycling of harmful materials in process gases generated during the production of polyurethane (PUR) block soft foam. Activated charcoal is used for removing CC13F and TDI which are emitted with exhaust air during the conventional production process. Adsorption of TDI is an irreversible process, which eliminates the option of recovering the TDI. The CC13F, however, is recovered through regeneration of the charcoal bed with hot steam.
