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 robber (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.
