Get this from a library. Steam stripping of fixed-bed gasification wastewaters. [F Douglas Skinner; Barbara J Hayes; Air and Energy Engineering Research Laboratory.]. The report gives results of laboratory- and bench-scale steam stripping tests, using wastewaters from a fixed-bed coal gasifier at the Department of Energy's Morgantown Energy Technology Center.

The wastewater was pretreated by solvent extraction (for phenol removal) and filtered prior to stripping. @article{osti_, title = {Gasifier wastewater treatment: Phase I cooling tower assessment}, author = {Mann, M D and Willson, W G and Hendrikson, J G and Winton, S L}, abstractNote = {The principle goal of the gasification research at UNDERC is to develop environmental data on the treatability of wastewaters from the fixed-bed gasification of lignite.

Steam stripping of fixed-bed gasification wastewaters [] Skinner, F. Douglas. Research Triangle Park, NC: U.S. Environmental Protection Agency, Air and. Gasification of biomass is an attractive technology for combined heat and power production as well as for synthesis processes such as production of liquid and gaseous biofuels.

Dual fluidised bed (DFB) technology offers the advantage of a nearly nitrogen-free product gas mainly consisting of H2, CO, CO2 and CH4. The DFB steam gasification process has been developed at Cited by: Lurgi FBDB™ - Fixed Bed Dry Bottom Gasification Gasifying solid carbonaceous feedstock With Lurgi FBDB™ - Fixed Bed Dry Bottom Gasification, syngas (composed of hydrogen and carbon monoxide) can be generated from solid carbonaceous feedstock (e.g.

Acid–Base Chemistry of Coal Gasification Wastewaters Table VII shows that alkalinity values in Hygas and Synthane wastewaters are noticeably higher than in coke plant ammonia liquor. This results from the presence of relatively high Steam stripping of fixed-bed gasification wastewaters book pressures of ammonia and Cited by: 2.

The reaction gas (raw gas) is mainly comprised of CO and H 2, but also contains about % CO2, % CH 4, and % soot depending on the feedstock quality. The CO to H 2 ratio depends on the.

The gasification system was originally designed for the thermal conversion of biomass aiming at the generation of high quality product gas.

Steam is used as the fluidization and gasification agent in the gasification reactor of the DFB system and, therefore, the product gas has a high hydrogen content (>40%) and a moderate lower calorific value of 12–14 MJ/N m 3, when wood is by: • A hydrogen source is needed for regeneration.

• Stripper requires steam, i.e., high energy inputs. • The steam used in regeneration results in an acidic wastewater stream.

(In the pilot plant, the steam is vented to the stack with the regeneration off-gas.) D   We discuss an equilibrium model of a fixed-bed solid fuel gasification process that takes into account macrokinetic constraints imposed on the rates of heterophase processes and allows the pyrolysis and gasification processes to be described in a fairly simple manner with the use of thermal analysis data.

The results of calculations are compared with the measured parameters characterizing Cited by: 7. Sulfide removal from wastewater by steam stripping is not commonly practiced in the coke oven industry.

Phenols are being removed by solvent extraction, steam stripping and/or biological oxidation, and carbon adsorption. Biological treatment has been successful with coke oven wastewaters in meeting existing phenol regulatory limitation. A dual loop gasification system [17, 18], which has a gasifier for steam gasification and a combustor for residual char combustion, appears to be attractive to sustain the gasification process.

gasification is predestined for decentralized energy systems. Fixed bed gasification is predominantly in this lower power range, since fluidised bed or entrained flow gasification usually demand for higher plant size for economic fea-sibility.

Different gasifying agents used in fixed bed Different gasifying agents used in fixed bed are shown in Table 2 The process of gasification Gasification is the conversion process of biomass to producer by heating in an oxidant or.

Biogass gasification works well for small scale power production, upto a maximum capacity of 2 MW. Combustion, on the other hand, works well at MW scales. The gasifier is the key component in a biomass gasification system. There are two main categories of gasifiers fixed bed and fluidized bed.

In this study, isothermal gasification experiments were performed using a fixed bed system mainly involving a reactant gas control part, a tube furnace reactor, a Cited by: The effects of different sewage sludge fractions in the mixture with woodchips on product yields, gas composition, gross heating value and gasification performance are investigated.

These results can help us better understand co-gasification of sewage sludge and biomass in a fixed-bed downdraft gasifier. parallel operation of a fixed bed gasifier and a bubbling fluidized bed reactor as combustor. Biomass is fed into the fixed, dried, pyrolised, and gasified.

Municipal waste is used as fuel and silica sand as bed material. Steam is used in the upper part of the fixed bed as well as in the loop seals.

A high quality product gas with a lower. The fabrication of a fixed-bed catalyst from the same Inconel material used in the reactor, for example, increased gasification efficiency four-fold (Ding et al., ).

The gas yield obtained in the steam gasification of HDPE ( g/ g of HDPE) is more than times higher than that obtained in the gasification of biomass.

Moreover, the tar content in the gaseous stream is ten times higher in the gasification of biomass ( g Nm-3 on a dry basis) than in the gasification of pure HDPE ( g Nm-3 on a. Among the various renewable energy sources, biohydrogen is gaining a lot of traction as it has very high efficiency of conversion to usable power with less pollutant generation.
