Analysis method of carbon fiber tail gas absorption unit in hydrogen peroxide production

An analysis method of a carbon fiber tail gas absorption unit in hydrogen peroxide production comprises the following steps that a carbon fiber box body is connected with a vacuum pipe, the vacuum pipe is connected with a vacuum pump through a heat exchanger, and an ultraviolet lamp is installed in the carbon fiber box body; the tail gas enters the carbon fiber box body for adsorption operation, and the tail gas is emptied; then saturated steam is injected into the carbon fiber box body for steam desorption, then an ultraviolet lamp and a vacuum pump are turned on for gas extraction, and after desorption, mixed gas composed of steam and residual tail gas in the carbon fiber box body is extracted out of the carbon fiber box body; the residual tail gas enters a gas-liquid separator after being cooled by a plate heat exchanger, aromatic hydrocarbon gas in the residual tail gas is liquefied and then combined with steam liquefied water into a liquid phase, the liquid phase enters a waste aromatic hydrocarbon stora
