TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The anaerobic digestion involves digesting concentrated agricultural waste, where the waste has a solids content of 4 - 8 %, and is heated prior to digestion. Prior to anaerobic digestion, the agricultural waste is concentrated up to approximately 30 % solids, and the concentrated agricultural waste is contacted with water to produce the agricultural waste stream having a solids content of 4 - 8 %. The anaerobic digestion has a retention time of less than 30 days. The biogas produced by anaerobic digestion is purified to form a cleaned biogas stream prior to reforming. For purification, the biogas is passed through a solvent vessel to remove entrained H2S.The biogas is purified to produce a cleaned biogas stream by separating entrained moisture from the biogas by passing the gas through an inlet separator; compressing the separated gas in a feed gas compressor; and removing hydrogen sulfide in a hydrogen sulfide absorber by contacting the compressed gas stream with methyldiethanolamine. The biogas is reformed by heating the biogas; mixing the heated biogas with steam in the presence of a catalyst to form a hot syngas stream; and cooling the hot syngas stream to form a syngas stream, that comprises (mol.%): hydrogen (69), carbon dioxide (13), and carbon monoxide (17). The conversion of the syngas to methanol involves compressing the syngas; converting the resultant hot, compressed syngas into methanol in a methanol converter to form a hot methanol stream; cooling the hot methanol stream to form a condensed methanol stream; and separating condensed methanol from gas in a methanol separator. Additional carbon dioxide is not added to convert the syngas into methanol. At least a portion of the solids remaining after anaerobic digestion are removed and treated to form fertilizer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Catalyst: The methanol converter is a catalytic reactor containing a catalyst selected from ZnO-Cr3O3 and CuO-ZnO-Al2O3.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred System: The system further includes a biogas purification system and a distillation unit to distill the methanol product. The biogas purification system comprises an inlet separator to separate entrained moisture from the biogas; a teed gas compressor to compress the separated gas and to form the compressed gas stream; and the hydrogen sulfide absorber. The biogas reformation apparatus is formed of a heater to heat the biogas; a reformer; and a heat exchanger to cool the hot syngas stream with compressed air to form the syngas stream and a hot air stream. The biogas reformation apparatus further includes an electricity generating apparatus. The electricity generating apparatus comprises a compressor to compress the hot air stream from the heat exchanger, a turbine engine connected to the compressor and to an electrical generator by a common shaft; a combustion apparatus connected to the compressor and turbine engine to provide hot compressed air to the turbine engine; and the electrical generator connected to the turbine engine by the common shaft. The distillation unit is a two-column distillation system formed of a product cooler to heat the methanol with a product methanol stream; a topping column to remove lights; and a refining column to produce a product methanol stream. The refining column comprises at least one refining reflux condenser. The topping column is formed of a column reflux condenser and a purge condenser. ACTIVITY - Fertilizer.
