Treść
Gasification is regarded as the most promising technique considering both syngas and energy pro - duction. It is a process during which the solid fuels at proper process conditions and at presence of a gasification agent are converted into gaseous products. The finally obtained gas, however, besides desired gases, contains also a range of inorganic and organic contaminants, which need to be removed before its further processing. The use of various gas cleaning techniques is always accompanied by the formation of a highly loaded wastewater. Its proper utilization is said to be the key for gasification popularization and commercialization, especially in case of the use of solid alternative fuels and small and medium installations. In the presented study, ultrafiltration of gasification wastewater was per - formed as a method for preliminary stream treatment. Two polyethersulphone membranes differed in cutoff, that is, 50 and 30 kDa, were investigated at various transmembrane pressures ranging from 0.2 to 0.3 MPa. The obtained results showed that the method could be used for preparation of the stream for further treatment by means of, for example, nanofiltration or advanced oxidation, while the con - centrate could be recycled to the gasification reactor.
