NOVELTY - Method for extracting biomass oil from biomass in a biomass-related process, involves (a) obtaining biomass-based product from biomass-related process, (b) applying an alkyl acetate solvent to the biomass-based product to extract oil to produce an extraction solution of at least biomass-based product solids, oil, solvent and water, (c) separating the extraction solution into a first phase containing solvent and oil and a second phase containing at least one of water and solids, and (d) separating the first phase from the second phase and removing the solvent from the oil.    USE - The methods are useful for extracting biomass oil from biomass in a biomass-related process, production of syngas from oil containing biomass-based product, production of co-products from alcohol or biofuel production process, and drying a wet solid co-product containing an amount of moisture from an alcohol or biofuel production process. The system is useful for removing oil from biomass-based products before fermentation in an alcohol or biofuel production. The syngas is useful to produce at least one of anhydrous ammonia, dimethyl ether, mixed alcohols, diesel, methanol, butanol and hydrogen (all claimed). The biomass includes corn, sugarcane, hemp, willow, Sorghum, wheat, barley, rice, and animal or agricultural waste. The co-products include steam, electric power and chemicals.    ADVANTAGE - The methods utilize waste products as raw material.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) production of synthetic gas (syngas) from oil containing biomass-based product, involves obtaining biomass from a biomass harvesting process, placing the biomass in a particle size reduction process to form a reduced size biomass-based product, feeding the reduced particle size biomass-based product along with an oxidant, into a pressurized gasifier to produce syngas, cooling the syngas in a boiler for heat recovery, removing sulfur compounds from the syngas, cooling the syngas further for conducting a water gas shift reaction to produce shifted syngas, removing a percentage of moisture content in the shifted syngas using direct or indirect condensers, applying compression and further removing a percentage of the moisture content in the shifted syngas using direct or indirect condensers and producing syngas with a higher purity level of hydrogen and separating syngas from low energy fuel gas in a pressure swing adsorption unit;    (2) production of co-products from alcohol or biofuel production process;    (3) method for drying a wet solid co-product containing an amount of moisture from an alcohol or biofuel production process, involves obtaining an ethanol stream from the production process, or an alkyl acetate stream, converting the ethanol or alkyl acetate into an azeotrope, applying the azeotrope to a wet solid co-product to remove moisture and form an ethanol or alkyl acetate rich solid co-product, applying a stream of hot carbon dioxide gas from the alcohol or biofuel production process to the ethanol or alkyl acetate rich solid co-product to remove ethanol or alkyl acetate from the solid co-product and form an ethanol or alkyl acetate-carbon dioxide stream, condensing the ethanol or alkyl acetate from the ethanol or alkyl acetate/carbon dioxide stream and recycling the carbon dioxide back into the production process, thereby leaving a dried solid co-product; and    (4) system for removing oil from biomass-based products before fermentation in an alcohol or biofuel production.
