Abstract: An apparatus and process for adsorbing volatile organic compounds, or VOCs, and efficiently regenerating adsorbent material in an emission control system. Flue gas, emitted from a combustion unit burning an outside fuel and desorbed VOCs, is humidified and cooled with a set of water injectors. The resultant humidified flue gas is directed through the adsorbent material, which is rapidly superheated without pressurization. A method for controlling the regeneration cycle of the emission control system includes at least three sensor configurations including a breakthrough sensor, a desorbed gas sensor and a flue gas temperature sensor.

Abstract: In a system for delivering vapor from a container partially filled with liquid to be vaporized by bubbling a carrier gas therethrough, the flow of the vapor is precisely regulated by a controller so as to provide a uniform mass flow rate of vapor. The controller is programmed to receive signals representing the sensing of the total gaseous pressure, temperature and liquid level in the container and to use the signals in a computation according to the following formula:m*=AF.sub.c (1+B.DELTA.T-C.DELTA.P-DF.sub.c +E.DELTA.L)whereinm*=Approximate vapor mass flowF.sub.c =Carrier gas mass flow.DELTA.T=Temperature variation from nominal (T-T.sub.o).DELTA.P=Pressure variation from nominal=(P-P.sub.o).DELTA.L=Charge in liquid level=-.intg.m*dtA,B and C=Positive constants computed for each chemical and nominal operating conditions; andD and E=Positive or negative constants computed for each chemical and nominal operating conditions.
