Embodiment Construction

[0025] The following embodiments are exemplary. Although the specification may refer to "one" or "some" embodiments in various places in the text, this does not necessarily mean that every reference is made to the same embodiment or that a particular feature applies only to a single implementation. Single features of different embodiments may also be combined to provide other embodiments.

[0026] figure 1 An example of a system according to an embodiment is shown. The system 100 comprises a combined heat and power (CHP) plant 102, an interface 114 for feeding biogas to a transport fuel production unit 104, an interface 114 to a district heating system 106a and to the grid 106b, and a hydrolysis unit 108, a digestion unit 110, Dryer 116 and heat recovery unit 112, and granulator 105, are operatively coupled to transfer heat, processed intermediate and final products. The coupling may be achieved by structures comprising, for example, pipes, heat transfer units and valves k...

Abstract

The invention provides a system (100) and method for processing biomass. The system comprises a combined heat and power plant (102), an interface (114) for feeding biogas to a traffic fuel production unit, interfaces (114) to a district heating system (106a) and an electrical grid (106b), and a hydrolysis device (108), a digestion device (110), a dryer (116) and a heat recovery unit (112), which are operatively coupled for transferring heat, intermediate products and final products of the process, wherein raw biomass is received into the hydrolysis device (108), biomass processed by the hydrolysis device (108) is fed to the digestion device (110), biogas obtained in the digestion device (110) is fed to the traffic fuel production unit (104), heat is recovered from the hydrolysis device (108), biomass processed by the digestion device (110) is dried by the heat recovered from the hydrolysis device (108), heat is recovered from the dryer (116), heat recovered from the dryer (116) is fed to the hydrolysis device (108) to be used in pre-heating of the received raw biomass, heat recovered from the dryer (116) is fed to the district heating (106a), and production of electricity is fueled by the dried biomass from the dryer (116).

Description

Background technique [0001] The National Renewable Energy Laboratory (NREL) proposed the concept of co-location of bioethanol production equipment and combined heat and power (CHP) equipment in November 2002 NREL / SR-510-33000 to utilize CHP heat and heat in biofuel production. electricity. The report proposes the idea of ​​using leftover biomass (called lignin) as part of the CHP fuel. [0002] Christensen et al. define a method and apparatus for thermal hydrolysis in patent US2010041119A Method and apparatus for converting cellulosic material into ethanol. This patent defines the separation and co-firing of lignin in a CHP unit connected to the grid. [0003] ST1 / Ahokas et al in WO2009141495(A1) define a method and apparatus for bioethanol production. The patent states that the dry matter will be used as biofuel to partly provide the heat to be used in the hydrolysis, fermentation, evaporation and dehydration units.
