Definitions
- hydrohalic acids preferably hydrochloric acid
- hydrolytically in the cold about room temperature.
- Known methods are described in DE 927139 and DE 3539492. Fundamental to the successful industrial application is the economic management of hydrochloric acid in the cycle. This leadership of the acid itself must meet important requirements.
- hydrochloric acid must be available in the desired concentration as well as amount for the digestion of the biomass. It is known that hydrochloric acid of different concentration is used successively for the fractionated digestion of biomasses (see DE 927139). These different fractions must be continuously supplied in the required quantity.
- the starting point here should be the process step of hydrolysis.
- the technical realization of the hydrolysis has been solved in many ways. However, it is always in the filling of a suitable reactor with biomass, which by means of concentrated Hydrochloric acid is digested. Hydrochloric acid is added and closes depending on
- Plant biomass of any kind wood, straw, energy crops, carcasses, mixtures of different biomasses
- This biomass can be pelleted, unpelleted or filled in a mixture of pelleted and unpellated material (see DE 102012020166).
- hydrochloric acid 35 to 37% hydrochloric acid is slowly passed through the reactor from bottom to top.
- the hemicelluloses from the biomass composite preferably dissolve, but other herbal ingredients are also dissolved. This fraction is withdrawn at the top of the reactor.
- hydrochloric acid is introduced from below through the reactor into the reactor. Due to its density, this hydrochloric acid displaces the low-concentration acid present in the reactor. The flow rate of the acid is measured so that the displacement leads only to a minimum mixing of the acid fractions. This higher concentrated acid fraction preferably dissolves the cellulose present and can be withdrawn anywhere.
- the hydrolysis step is not yet complete. In order to recirculate all acid, it must be completely removed from the reactor. It should be noted that the residue present in the reactor (lignin) itself binds hydrochloric acid. In the past, it was therefore necessary to ensure that all the free acid present in the reactor was displaced and that the hydrochloric acid bound to the lignin was removed again. This was preferably done by slowly introducing
- washing water fraction which initially contained considerable amounts of hydrochloric acid.
- residual amounts of hydrochloric acid could only be removed by using large amounts of water, so that in the concentration profile a so-called "washing tail", characterized by low
- the sugar / acid fraction is sent to the process step of evaporation.
- hydrochloric acid and water in addition to other volatile substances (released from the biomass, such as acetic acid) evaporated from the sugar and other valuable substances.
- considerable amounts of water vapor were also needed to drive off residual hydrochloric acid.
- a good overview of the usual three-stage process is DE 3539492. It is important to note that ALWAYS hydrochloric acid losses occur during evaporation. A small proportion of hydrochloric acid thus remains at the sugar / recyclable fraction. A 100% recycling is current the evaporator technology not possible.
- the washing water fraction is not subjected to the energy-intensive evaporation due to their low proportion of recyclables. It immediately goes into the process step of acid processing.
- the process step of the acid work-up is of fundamental importance for the acidification, as it closes the acid cycle.
- All requirements are met, which have already been named above.
- the handling of the lignin is separated according to the prior art from the leadership of hydrochloric acid. It is removed from the hydrolysis reactors and fed to thermal utilization (incineration). In the past, a drainage by means of pressing was usually preceded to increase the potential energy gain. The flue gases were finally emitted in compliance with legal requirements. A special idea is in DE 3539492 described. There, the lignin is passed through the evaporation together with the sugar / acid fraction and freed together with this from the hydrochloric acid. However, this concept has never been realized in large scale engineering. With the processing of the lignin, a part of the entrained water is effectively discharged again. Press water has been used in wastewater treatment in the past. The flue gases also contain water and have been emitted in the past. In proportion to the proportion of water that is discharged in the acid workup, this amount is much lower.
- the entry of water occurs (at least) in the process step of hydrolysis (to displace the acid) and in the process step of evaporation (by adding water vapor as a means to expel residual hydrochloric acid).
- the discharge of water is mainly due to the process step of acid processing and partly in the process steps of lignin utilization.
- Wash tail usually discharges only small amounts of hydrochloric acid with the aid of considerable amounts of water and is virtually cut away.
- the residence time of the lignin in the hydrolysis reactor is significantly reduced. This increases the space / time yield, at the same time reduces the expenditure on equipment.
- This acidic lignin is now subjected to the known steps of the prior art. There is a drainage with subsequent combustion. Since the resulting streams contain hydrochloric acid or HCl gas, they must be included in the leadership of the acid. Thus, the press water from the drainage in acid processing are performed. Exhaust gases from combustion are freed of HCl gases with a flue gas scrubber.
- hydrochloric acid is produced by accepting a water input. However, this is much more concentrated than the prior art wash water resulting from the hydrolysis. This hydrochloric acid is also passed as makeup in the process step of the work-up.
- the introduced changes reduce the amount of water that is effectively forced into the process.
- a second acid cycle which includes the process steps hydrolysis, lignin processing (at least including the combustion), flue gas scrubbing and acid workup in the order listed.
- streams from the lignin workup can be fed directly into the hydrolysis.
- the press water can be used directly for washing out the hydrolysis reactors. Then the task of acid processing would consist exclusively in the storage of the resulting hydrochloric acid streams.
- DE 102011104723 documents an effective method for removing hydrochloric acid from biomass hydrolysates. With the help of a heated heat carrier, evaporation can take place completely and without additional water input.
