APPARATUS FOR REMOVING HALOGEN HYDRACIDS FROM BIOMASS HYDROLYSATES

摘要

An apparatus for removing hydrogen halide and water from hydrolysates that were obtained by way of halogen-acid hydrolysis from vegetable biomasses, characterized in that: - said apparatus comprises two containers, which are connected to each other by a tube, - at the inlet of the first container two flows are fed, one representing the hydrolysates and the other a heat transfer medium, which dissolves in the hydrolysate only to an economically justifiable extent (no additional process steps due to potential contamination during mixing), or enriches matter therefrom, - both flows are sprayed together in the first container, thereby producing a homogeneous mixing of the two flows, including heat transfer, which subsequently results in complete evaporation of water and the hydrogen halide dissolved in the hydrolysates, - the evaporation produces a mixture of granular solid bodies and heat transfer medium droplets, which is pulled from the first container into the second container via the connecting tube by way of a pressure gradient, - the second container is configured as a cyclone or centrifugal force precipitator, and a separation of liquid (heat transfer medium droplets) and solid constituents (granular solid bodies) from the gas flow takes place. An apparatus, characterized in that the second container (here: cyclone) on the inside wall may be lined with polyvinylchloride [PVC] (hard), PVC (chlorinated), polyethylene (PE), polypropylene (PP), polybutylene (PB), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), ethylene-propylene-diene rubber (EPDM), ethylene-propylene copolymer, ethylene-tetrafluoroethylene (ETFE), perfluoro-ethylene-propylene plastic (FEP), fluoropolymer plastics (FPM and FKM = group designation), perfluoro trifluoroethylene (PCTFE), perfluorinated rubber (FFPM and FFKM), butyl rubber (HR), isoprene rubber (IR), chlorinated polyethylene (PE-C) and rubber (collective term for rubbers containing sulfur) and copolymers and mixtures thereof from said polymers, or comprises them.
