Abstract: A feed stream including hydrogen sulfide is heated to a preheat temperature. At least a portion of the hydrogen sulfide in the feed stream is converted into hydrogen and sulfur to form a mixed product stream including the hydrogen, the sulfur, and a remaining, unconverted portion of the hydrogen sulfide. The preheat temperature is a temperature that is sufficiently hot to maintain a desired reaction temperature while converting at least the portion of the hydrogen sulfide in the feed stream into hydrogen and sulfur. At least a portion of the mixed product stream is cooled to a specified temperature at which recombination of the hydrogen and the sulfur into hydrogen sulfide is prevented. Cooling at least the portion of the mixed product stream includes condensing at least a portion of the sulfur to form a sulfur stream.

Abstract: A feed stream is heated to a preheat temperature. The feed stream includes hydrogen sulfide. After heating the feed stream, at least a portion of the hydrogen sulfide in the feed stream is converted into hydrogen and sulfur to form a mixed product stream. The mixed product stream includes the hydrogen, the sulfur, and a remaining, unconverted portion of the hydrogen sulfide. The preheat temperature is a temperature that is sufficiently hot to maintain a desired reaction temperature while converting at least the portion of the hydrogen sulfide in the feed stream into hydrogen and sulfur. At least a portion of the mixed product stream is cooled to condense the sulfur to form a sulfur stream. The sulfur stream includes the sulfur that has condensed from the portion of the mixed product stream.

Abstract: The disclosure relates to systems and methods to produce hydrogen (H2) gas from hydrogen sulfide (H2S). H2S is contacted with a catalyst to form H2 gas and sulfur adsorbed to the catalyst.

Abstract: The disclosure relates to systems and methods where an adsorption-based modularized gas storage system is integrated with existing off-network gas distribution pipelines, which can increase the system reliability and robustness for delivering gas. The modularized gas storage system is placed downstream of a natural gas producing well and upstream of a gas-based power plant. The modularized gas storage system can increase the capacity of the overall network, which can allow the pipeline network to absorb the fluctuations in gas demand with little if any need to adjust gas production rate and/or while sacrificing little if any survival time. The storage system can also release the stored gas in the case of an urgent need for gas (e.g., due to a shutdown of a natural gas producing well) to satisfy a desired survival time.

Abstract: The disclosure relates to systems and methods for a heat management system in a gas storage system that includes an expander, such as, for example, a sliding vane expander or a pelton expander. The expander can generate work (e.g., electricity) from the pressure drop of a coolant fluid. The work can be used by a compressor in a heat pump.
