STEAM EXPLOSION METHODS BEFORE GASIFICATION

An integrated plant that includes a steam explosion process unit and biomass gasifier to generate syngas from biomass is discussed. A steam explosion process unit applies a combination of heat, pressure, and moisture to the biomass to make the biomass into a moist fine particle form. The steam explo...

Zusammenfassung:	An integrated plant that includes a steam explosion process unit and biomass gasifier to generate syngas from biomass is discussed. A steam explosion process unit applies a combination of heat, pressure, and moisture to the biomass to make the biomass into a moist fine particle form. The steam explosion process unit applies steam with a high pressure to heat and pressurize any gases and fluids present inside the biomass to internally blow apart the bulk structure of the biomass via a rapid depressurization of the biomass with the increased moisture content. Those produced moist fine particles of biomass are subsequently fed to a feed section of the biomass gasifier, which reacts the biomass particles in a rapid biomass gasification reaction to produce syngas components. L'invention concerne une installation intégrée qui comprend une unité de procédé de vapocraquage et un gazéificateur de biomasse pour produire un syngaz à partir de biomasse. Une unité de vapocraquage applique une combinaison de chaleur, de pression et d'humidité à la biomasse pour donner à la biomasse une forme de fines particules humides. L'unité de vapocraquage applique de la vapeur à haute pression pour chauffer et pressuriser tous les gaz et les fluides présents à l'intérieur de la biomasse pour faire éclater de l'intérieur la structure générale de la biomasse par une dépressurisation rapide de la biomasse avec la teneur en humidité accrue. Ces fines particules humides de biomasse produites sont ensuite introduites dans une section d'alimentation du gazéificateur de biomasse, qui fait réagir les particules de biomasse dans une réaction de gazéification de biomasse rapide afin de produire des composants de syngaz.
