Definitions

  • the field of the invention relates to delivery of steam produced by an electrical power generation plant to a lignocellulosic biomass refinery.
  • second generation bioethanol produced from lignocellulosic biomass such as crop wastes (stalks, cobs, pits, stems, shells, husks, etc.), grasses, straws, wood chips, waste paper and the like.
  • fermentable 6-carbon sugars, and potentially fermentable 5-carbon sugars are liberated from biomass polysaccharide polymer chains by enzymatic hydrolysis or, in some cases, by pure chemical hydrolysis.
  • the fermentable sugars obtained from biomass conversion can be used to produce fuel ethanol or, alternatively, other fuels such as butanol, or lactic acid monomers for use in synthesis of bioplastics, or many other products.
  • hydrothermal pretreatments are especially attractive. These utilize pressurized steam/liquid hot water at temperatures on the order of 160 - 230 o C to gently melt hydrophobic lignin that is intricately associated with cellulose strands, to solubilize a major component of hemicellulose, rich in 5 carbon sugars, and to disrupt cellulose strands so as to improve accessibility to productive enzyme binding. Hydrothermal pretreatment does not require any added industrial chemicals and can be conveniently integrated with existing coal- and biomass-fired electrical power generation plants to efficiently utilize turbine steam and "excess" power production capacity.
  • steam supply for the biomass refinery is produced first by pressurizing comparatively low temperature water ( ⁇ 100 o C) to a desired final pressure then heating the pressurized water to a final steam temperature by means of a series of heat exchangers fed by turbine steam.
  • Power generation plants are typically configured so as to provide discrete extraction points where turbine steam may be extracted for other purposes. However these extraction points typically extract steam having a definite pressure. It can occur that a power generation plant is configured to provide extraction steam at pressures that do not correspond to the steam pressure requirements of the biomass refinery. Accordingly, where steam is provided directly by the power generation plant to the biomass refinery, there can often be
  • At least one compressor for pressurizing low temperature water to pressures of at least 5 bar
  • FIG. 1 shows a schematic illustration of one preferred embodiment of a system according to the invention.
  • Two separate pre-heating trains are used to provide steam at two different final pressures of 10 and 20 bar.
  • a compressor (1 ) compresses low temperature water to a final pressure of 10 bar.
  • compressed low temperature water is then heated by series of three counter-current heat exchangers (2) supplied with heat by extracted turbine steam (3) from an associated power generation plant.
  • the pre-heated, pressurized water is then conveyed as steam to biomass processing devices such as distillation units, dryers and evaporators by means of steam pipeline (4).
  • biomass processing devices such as distillation units, dryers and evaporators by means of steam pipeline (4).
  • a compressor (5) compresses low temperature water to a final pressure of 20 bar.
  • compressed low temperature water is then heated by series of three counter-current heat exchangers (6) supplied with heat by extracted turbine steam (7) from an associated power generation plant.
  • the pre-heated, pressurized water is then conveyed as steam to biomass processing devices such as hydrothermal pretreatment reactors by means of steam pipeline (8).
  • pre-heating trains may be configured in a variety of different ways, depending on the level of turbine steam pressure that is available for extraction from the power generation plant.
  • a steam delivery system according to the invention may be used in combination with an additional heat source.
  • 10 bar steam from a pre-heating train fed by turbine steam can be further super-heated to 20 bar steam using a gas-fired boiler.
  • methane gas for such a boiler can be provided by anaerobic digestion of waste water produced by the biomass refinery.
