Definitions
- the present invention relates to a system and method for treating gas from biomass gasification.
- the gasification of biomass in particular of wood, produces a syngas which is used for most refining processes (for example methanation, Fischer-Tropsch).
- Pollutants are in particular higher hydrocarbons (Schwflflticianrs, Schwerflticianr, especially aromatics, waxes and tars), and sulfur compounds (eg H 2 S, COS, thiols, sulfur-containing heteroaromatics). If it is possible to efficiently remove the pollutants from the synthesis gas, this can be used even for catalytic upgrading processes (eg methanation, Fischer-Tropsch reaction).
- the present invention is therefore based on the object of specifying a method and a system for the treatment of gas from a biomass gasification, which provides the gas with sufficient for the required service life in the refining process, for example by means of a catalyst purity.
- this object is achieved by a method for processing a synthesis gas originating from a biomass gasification, which comprises the following steps: a) one-stage or multi-stage cooling and / or quenching of the synthesis gas to a first temperature and a first pressure, where it is necessary to induce a partial condensation to separate heavy boilers; b) washing the cooled / quenched synthesis gas in an oil scrubber at a wash temperature that is in the range of the first temperature, wherein the withdrawn from the oil scrubber charged wash oil is thermally regenerated in a stripping column and / or by means of stripping gas and then cooled in the oil scrubber is recycled; c) optionally purifying the cooled / quenched and washed synthesis gas in a catalyst doped one
- a system for processing a synthesis gas originating from a biomass gasification which essentially comprises the following components: a) a first cooler or quencher stage which transfers the synthesis gas to a first temperature and a first pressure brings; optionally, a subsequent second cooler or quencher stage that brings the pre-cooled synthesis gas to a second temperature and a second pressure, the second temperature being lower than the first temperature; b) a downstream oil scrubber for washing the twice quenched or cooled synthesis gas at a washing temperature which is in the range of the second temperature, wherein the withdrawn from the scrubber loaded scrubbing oil thermally regenerated in a stripping and / or by stripping and then cooled in the oil scrubber recycled; c) if necessary, an adsorber stage downstream of the oil scrubber for purifying the quenched and washed synthesis gas using an adsorbent doped with a catalyst / activator (eg doped activated carbon), in particular
- a catalyst / activator eg doped activate
- the multistage prepurification described above by means of at least one cooling / quenching and an absorption / desorption stage and optionally reactive adsorption and optionally.
- HDS catalysis Hydrophilicity-Propanediolysis
- two cooling / quenching stages are present.
- the temperature of a single cooling / quenching stage should then be at the level of the absorption stage (oil scrubber).
- first temperature in the range of 0 to 70 0 C and the second temperature in the range of -20 to +30 0 C.
- Advantageous scrubber temperatures are in the range of the second temperature.
- a meaningful reuse of waste products from the refining process can be achieved if the stripping gas originates from the refining process, preferably as a CO 2 -rich gas from a CO 2 separation.
- a particularly good separation is made possible by removing some wash oil from the oil wash and adding fresh wash oil. As a result, heavy bottles, which can not be expelled in the desorption, be discharged from the wash cycle.
- Regeneration tasks to a minimum. For this reason, it is particularly expedient to carry out the adsorber stage and / or the chemisorber each redundant. In this way, one stage is always involved in the current process, while in the other stage, for example, the adsorbent or the chemisorber can be changed.
- FIG. 1 shows a schematic view of a schematic representation of the essential process modules for the preparation of a derived from the biomass gasification synthesis gas.
- Synthesis gas biomass gasification is usually cooled using heat energy to about 50 to 150 0 C and filtered (1). This gas is fed to a first cooler / quencher (QI). In this stage, the gas stream partially separates the first offers (tars, waxes and partly tar oils) and water, and at the same time cools to about the cooling water temperature. The separation of the organic phase (112) and the aqueous phase (113) takes place in a decanter (DI), and heat energy is dissipated in a quench cooler (QK-I). This level belongs to the state of
- the oil scrubbing after the second quencher stage is used to the gas stream (3) to extract any remaining absorbable pollutants (Schwerflticianr, especially aromatics, waxes and tars and thiols, sulfur-containing heteroaromatic) maximum.
- an oil-like liquid for example a suitable mineral oil fraction, a mineral oil derivative, a biodiesel such as rapeseed oil methyl ester, which has a high boiling point, in the oil scrubber (EW) and the pollutants are absorbed in the liquid phase.
- the loaded wash oil is thermally regenerated in a stripping column (ES) by means of an oil heater / evaporator (AE) and / or with stripping gas.
- the stripping gas (315) can in particular consist of a the refining stage downstream process stage (eg CO 2 -rich gas from the CO 2 separation).
- the regenerated wash oil on the scrubber (311) is cooled from the oil stripper via oil heat exchanger ( ⁇ WT) where heat is transferred to the loaded wash oil (312) and oil cooler (OK).
- the oil scrubber is preferably operated at a temperature of -20 to +30 0 C.
- Some fresh wash oil must be added (314).
- the combination of absorption (oil scrubber) and desorption (oil stripper) for this application is one of the key points, especially in combination with the reactive adsorption.
- a recirculation stream (eg, unreacted gases such as H 2 ) is added from the refining process following the refining process (6), with the addition at several points being meaningfully possible.
- the pressure increase usual for process engineering processes can take place at several places in the process, in particular after the oil wash or before the reactive adsorption. Usually, such a system is suitable for a pressure around atmosphere up to more than 70 bar.
- the gas (7) which is largely freed from absorbable pollutants, is enriched by a catalyst / activator
- Adsorbent passed (ADS-I or ADS-2, a fixed bed in operation, the other is replaced or is ready for operation or in series downstream).
- H 2 S is oxidized (and sometimes also COS), where elemental sulfur is formed, which is bound to the adsorbent.
- the oxygen required for this purpose is actively added, if it is not present anyway due to leaks in the gas flow (5). Remains of the most serious offenders and heavy refugees, who are still in the gas stream 7, are also retained on the adsorbent.
- This type of reaction of H 2 S into elemental sulfur and its binding to an adsorbent is based on known technology.
- gas heater gas heater
- GK gas cooler
- the purified gas (10) is then fed to a catalytic upgrading process.
