Oxygen for gasification

O2 separation Compressed air o2 Oxygen for gasification of fossil fuels (coal, heavy oil, biomass) Oxygen for oxy-fuel combustion Oxygen for combustion of remaining fuel from various process streams... [Pg.198]

Klosek, J., Sorensen, J. C., and Wong, W., Air versus oxygen for gasification combined cycle power, paper presented atVGB Conference — Buggenum IGCC Demonstration Plant, Maastrich, The Netherlands, November 1993. [Pg.356]

Substituting the ASU with membrane modules that provide the oxygen for gasification,... [Pg.394]

The use of air alone leads to a relatively low calorific value product gas, of the order of 4-6 MJ/mi (LHV basis), which is not attractive for H2 production in view of the large bulk of N2 to be separated from it compared to a preseparation from the air. Only the application of hydrogen in ammonia production would need N2 as cofeedstock. Therefore, in this context only steam- or oxygen-blown gasification concepts are dealt with. The raw product gas can, thus, be produced by an oxygen-blown or indirectly heated steam-blown processes. [Pg.205]

It is probable that development of satisfactory processes for gasification of pulverized coal with oxygen-steam mixtures would be expedited by additional laboratory research on the kinetics of the steam-carbon reaction (20) at temperatures between 1000° to... [Pg.144]

In oxygen deficient expls an appreciable fraction of the carbon product is in elemental form even though sufficient oxygen is present for gasification. This is a consequence of Le Chateliefs Principle that with increasing pressure the number of molecules of gaseous products tends to be minimized by a shift to condensed reaction products... [Pg.685]

Gasification involves adding substoichiometric levels of oxygen for partial oxidation of the char and the high-molecular-weight volatiles ... [Pg.116]

The gasification process involves the combustion of coal with a restricted amount of oxygen. For the most part the oxygen is provided by a separate air separation unit (ASU) rather than air which would otherwise introduce a large amount of nitrogen into the synthesis gas. The principal chemical reactions are ... [Pg.205]
