摘要：Based on the adsorption-thermal nitrogen cycle-shunt condensation organic gas recovery technology, this paper investigates the existing adsorption theories and engineering practices and studies the desorption part of this recovery process using a combination of theory and experiment so as to propose suggestions for improvements from the viewpoint of desorption rate and desorption effect. Based on the experimental conditions of this paper, when the cyclic desorption turndown ratio (the ratio of clean gas to total circulation gas) λ equals 0.5, it is more advantageous to increase the desorption rate of volatile organic compounds. Continuing to increase λ will increase energy consumption in actual engineering, but has no significant effect on either the desorption rate of activated carbon in the adsorption tank or the desorption effect. This provides reliable data and methods for efficient operation of this technology and energy saving.
