The main scope of this master thesis is the investigation of technical solutions that are able to eliminate harmful flue gas emissions which are caused by the in-situ combustion oil recovery process in the Romanian Suplacu de Barcu field. PETROM endeavours to comply with Romanian and EU regulations as well as internal HSE policies. Therefore, measures shall be implemented to significantly reduce waste gas emissions of the Suplacu field. One of the key elements of this thesis is the development of a system that provides a both reliable and economic method for the abatement of characteristic flue gas emissions at the points where they are collected by the existing piping infrastructure. Thereby, the underlying part was a comprehensive evaluation of current flue gas emissions and identified substances, mapping flue gas volumes and pollutant concentrations from all emitting sources across the extent of the field. After comparing the applicability of several environmental control methods, thermal oxidation systems turned out to be not even highly capable, but also adaptable enough to handle the estimated range of emissions and associated pollutants. To get closer to the target of the thesis, several types thermal oxidation concepts and main components of combustion system have been assessed. Incineration systems mentioned in the thesis were examined in relation to operational difficulties that are likely to be encountered for the given conditions, as well as performance criteria, involved capital and operational expenditures and potential methods for heat recovery. In order to come up with a practicable solution for the given concentration of pollutants, the problem was assigned and elaborated with well-experienced combustion technology vendors. Thereby emphasis was simultaneously put on a flexible design that allows a broad range of operating conditions, use of components that allow trouble-free and continuous system performance as well as maximum energy efficiency. A further topic of this thesis was a simulation study about potential thermal abatement systems including flue gas emissions from each individual collection facility. The information obtained was first of all used to determine the maximum capacity required for the future onset of pollutants and second, to provide firm budget pricing for the required system dimension. Furthermore the amount of heat recovered was analyzed and compared in terms of producible saturated steam generated by distinguished incineration systems.
