The process and system of the invention converts solid and liquid carbonaceous feedstock into electricity, steam, fuels, and carbon dioxide with minimal air emissions. Oxygen is partially consumed in a fuel cell then exhausted to a combustor of a Twin-Fluid Bed Steam Gasifier Unit (TFBSGU) where it is consumed in burning carbon contained in ash. After particulates are separated, the flue gas is expanded then cooled to recover power before returning to atmosphere or a bio-reactor. Synfuel leaving the TFBGSU is cooled in a heat recovery unit, producing steam and hot water. Carbon monoxide in this stream reacts with steam producing hydrogen and carbon dioxide. The stream is then cooled and compressed. The compressed gas passes through an acid gas removal system removing carbon dioxide and sulfur bearing compounds. Steam is added to the clean gas to prevent coking and the stream enters the anode space of the fuel cell.

An odor removal system to neutralize odors and VOC emissions released into the environment by commercial and / or industrial air streams utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and / or reduction of odor causing molecules and VOC's. The ROS is generated by drawing atmospheric and / or odorous air through a Dielectric Barrier Discharge Plasma Generation Cell (DBDPGC). The gas is activated by passing it through the non-thermal plasma field in the DBDPGC, producing the ROS that are then immediately mixed into the odorous gas stream to be treated, or if it is the odorous gas that is passing through the NTP field, it is inherently mixed. When large volumes of gas, and / or extremely high odor load in combination with large gas volumes must be treated, multiple units can be combined in parallel to treat the gas. The DBDPGC has hermetically sealed hot electrodes and may be used in other applications.

A Dielectric Barrier Discharge Plasma Generation Cell includes a plurality of hot electrodes interspersed with a plurality of ground electrodes whereby a power supply connected between the hot and ground electrodes creates a non-thermal plasma between the electrodes. The hot electrodes are hermetically sealed by a rubber material such as a siloxane material surrounding portions of the hot electrodes. The cells are useful in odor removal systems to neutralize odors and VOC emissions in commercial and / or industrial air streams and in gas purification and sterilizing systems which utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and / or reduction of odor causing molecules, VOC's, and other contaminants. Where a plurality of cells are electrically connected in parallel, shorts in a cell can be detected by sensing the difference in currents feed to each of the plurality of cells.
