Abstract: (Problem to be Solved) To provide a volatile organic compound recovery device which renders energy saving possible and renders the equipment simple. (Means for Solution) An untreated gas which contains a volatile organic compound is supplied to an adsorption tower (1), whereby the volatile organic compound is adsorbed onto the adsorbent. After completion of the adsorption, a volatile organic compound which has higher adsorbability than that of the volatile organic compound adsorbed onto the adsorbent is supplied to the adsorption tower (1) through a desorption gas supply valve (4). The volatile organic compound which has low-adsorbability and has been adsorbed onto the adsorbent is then desorbed therefrom due to competitive adsorption with the high-adsorbability volatile organic compound fed later, and the high-adsorbability volatile organic compound itself is adsorbed onto the adsorbent instead.

Abstract: In the partial-regeneration cycle gas turbine system wherein part of the air compressed by a compressor 2 is extracted before a combustor 3, mixed with steam, and after the mixed gas is superheated by exhaust heat of a turbine, and the mixed gas is injected into the combustor, high-pressure steam is used as a fluid for driving a first mixer 22 that compresses extracted air, to increase the ratio of extracted air to steam, and then this mixed gas of extracted air and steam is further mixed with low-pressure steam from a low-pressure exhaust heat boiler, in a second mixer, and the mixture of gas is superheated in a superheater 6 by exhaust heat of the turbine, and injected into the combustor. Thus, the pressure of the driving steam can be raised, an exergy loss in an exhaust heat recovery portion can be reduced, and the efficiency of power generation can be increased without reducing the flow of generated steam.

A steam-driven mixer boosts the air and mixes the steam and the air. A heat exchanger is arranged downstream of the turbine for heating the mixed gas from the mixer with heat from the turbine exhaust gas. A heat recovery steam generator is arranged downstream of the heat exchanger for producing steam with heat from the exhaust gas. An air line is provided for introducing a first portion of the compressed air from the compressor to the combustor and for introducing a second portion of the compressed air to the mixer.
