This theme focuses on integrated processes for removal and conversion of volatile sulfur compounds from aqueous solutions. These aqueous are used to scrub volatile sulfur compounds from oil and gas and have a high pH and salt concentration. The process scheme consists of scrubbers and bioreactors and aims at removal of all volatile sulfur compounds like sulfide and thiols (e.g. methanethiol). The water consumption of this process can become zero by treating the bleed stream enabling recycling of all water. The scientific disciplines needed for development of such an integrated process are chemistry, microbiology, biotechnology and modeling.
