Definitions

  • Yet another embodiment of the present invention is a. method for removing and recovering a volatile organic component from, a vapor stream including the steps of: (a) directing a flow of the vapor stream to a first carbon adsorption unit from a cooled heat exchanger; (b) measuring the vapor stream exiting from the first carbon adsorption unit for the volatile organic component; (c) releasing the exiting vapor stream from the first carbon adsorption unit into the atmosphere if a measured concentration of the volatile organic component is below a desired concentration; (d) diverting the flow of the vapor stream to a second carbon adsorption, unit whenever the measured concentration of the volatile organic component, in the vapor stream exiting from the first carbon adsorption unit, is equal to or greater than, the desired concentration; (e) lowering the pressure in the first carbon adsorption unit to deso.rb the volatile organic component; and (f) directing the desorbed volatile organic component through the cooled heat exchanger to condense a portion of the volatile organic
  • the vapor stream passes through the first condenser 21 and continues toward the second heat exchange condenser 22 through open valves 24B, 24C and 24D. Since the refrigerant is circulating through the second heat exchange condenser 22, the temperature in the second condenser 22 is lower than the temperature of the first heat exchange condenser 21. and is generally lower than the condensing temperature for the VOCs in the vapor stream. Thus, as the vapor stream passes through the second heat exchange condenser 2.2 and is cooled by the refrigerant, condensate from the volatile organic components in the cooled vapor stream will accumulate at the bottom of the second condenser 22.
  • the condensate may be drained manually opening the valve 29A into a condensate collection vessel 15, or alternatively the condensate may be drained automatically using a controller that monitors a liquid level in the condenser to send a signal to open the valve 29A and allow the condensate to drain from the first condenser 21 into the condensate collection vessel 15.
  • the direction of the flow of the vapor stream is reversed either at preset time intervals (e.g. * 10-30 minutes) or whenever the pressure across one or both of the condensers drops to a particular setpoint,

Abstract

La présente invention concerne l'extraction de vapeurs volatiles d'un récipient de stockage en établissant une circulation d'un courant de vapeurs volatiles issues du récipient de stockage et en dirigeant le courant de vapeurs à travers un module d'échange thermique afin de condenser une partie des vapeurs dans le courant circulant à travers des condenseurs d'échange thermique refroidis dans le module d'échange thermique. Les vapeurs non condensées dans le courant de vapeurs sont alors dirigées vers un module d'adsorption de carbone comprenant deux unités d'adsorption de carbone. Le système de récupération de vapeurs offre également un moyen de désorber une unité d'adsorption de carbone qui approche sa capacité pour adsorber les molécules organiques volatiles et recycler le courant de vapeurs désorbées à travers un condenseur d'échange thermique refroidi afin de transformer la matière organique volatile en état liquide pouvant être vendue comme produit ou utilisée comme matière première plutôt que d'être brûlée ou autrement libérée dans l'atmosphère.
