“…Pipeline natural gas is the primary fuel of choice for distributed fuel cell-based power-generation systems due to its abundant supply and well-developed infrastructure. Natural gas is composed of low boiling hydrocarbons (mostly methane) and much smaller amounts of nitrogen, carbon dioxide, water vapour and sulphur compounds [2]. Possibility of environmental contamination by natural gas is relatively small.…”

The paper presents the results of the spread of the tetrahydrothiophene (THT) - used as odourant - in the gas network. Such analyses allow quick detection of leaks in networks, systems and devices of gas supply directly to consumers. The main goal of the study was to determine the effectiveness of the use of portable chromatograph and comparing it with a stationary odourant concentration analyser. Based on these studies, an attempt to determine the odouration zone for the selected city have been also taken. For this purpose, three series of measurements were made - in each series 13 points were analysed. Obtained results confirmed the effectiveness of the measurement a concentration of odourant in the gas network using a portable gas chromatograph - difference in relation to the stationary chromatograph ranged from 1.91 to 2.55 %.

“…Some common solid sorbents used in selective adsorption of sulfur compounds from fuels include ion-exchanged or metal-containing zeolites, supported metals, metal oxides, metal-containing aluminum oxide, activated carbons, and modified mesoporous silica. − Zeolites are attractive sorbents due to their large pores and surface area, polarity, high thermal stability, and surface sites that lead to high capacities for sulfur removal. Zeolites X, Y, ZSM-5, and USY have all been used successfully in many studies for adsorbing various sulfur compounds from different fuels. , Zeolites can be easily regenerated with heat or vacuum, and can be pressed into pellets for use in a fixed bed or spun into fibers for use in a fiber module. , …”

Sulfur odorant removal from pipeline natural gas can prevent or delay corrosion in gas turbines to increase their lifetime and efficiency. Removal of the odorant tert-butyl mercaptan (TBM) by selective adsorption with fiber sorbent modules and removal with pellet packed beds are compared in terms of capital and operating costs. Capital costs are estimated based on sizing the equipment items needed for each system, which varies depending on the regeneration gas used. Operating costs are estimated based on the utilities needed to run each system, again varying depending on the regeneration gas used, and also on whether heat integration is considered. Using a fraction of the product gas for regeneration is safer, simpler, and more economical than compressed air or nitrogen. Due to the need for more adsorber beds to process the same amount of TBM-containing pipeline natural gas, the capital cost associated with the pellet packed bed system is significantly higher than that of the fiber sorbent system. Heat integration with the sorption system by using the energy generated from waste gas combustion to produce steam dramatically decreases the operating cost by reducing the parasitic load. Overall, this process analysis shows that the fiber sorbent system with heat integration can be an attractive technology compared to packed bed systems for TBM removal.
