Figure 4.7 Influence of oxygen concentration (purity of oxygen) on a dry-feed entrained-flow gasifier (Shell) at 1450°C and 30 bar employing Pitt 8 coal. Figure 4.7 Influence of oxygen concentration (purity of oxygen) on a dry-feed entrained-flow gasifier (Shell) at 1450°C and 30 bar employing Pitt 8 coal.
The Shell process uses partial oxygen gasification. Because insufficient oxygen exists for complete combustion (20-30% of the oxygen required for complete combustion is used), only a fraction of carbon in the coal is oxidized completely to C02. The heat released from this combustion provides most of the energy needed for endothermic coal gasification reactions and raises the gasifier temperature. Some steam is usually added to prevent excessive... [Pg.110]

The Texaco gasification process, currently owned by GE, is also of the EF type. A main difference with the aforementioned technologies is that the fuel is fed as a water slurry, whereas Koppers-Totzek- and Shell-based coal gasifiers use some steam. [Pg.203]

European refinery gasification projects include the API project in Falconara, Italy Sarlux project in Sardinia, Italy ISAB project in Sicily, Italy and Shell project in Pemis, Netherlands. Several plants are also reported to gasify biomass to produce gaseous fuels or electric power. [Pg.5]

This technology has already been described. Some general characteristics The gasifier is a two-stage pressure shell lined with refractory material in which coal to be gasified is injected as a preheated slurry. The dry coal concentrations in the slurry range from 50 to 70 wt%, depending on the inherent moisture and quality of the feed. Part of the... [Pg.94]

Biomass gasification processes are in the demonstration phase. Biomass can also be gasified together with coal. Royal Dutch/Shell has commercially demonstrated a 25/75 biomass/coal gasifier. [Pg.113]
