Abstract
Microalgae may sequester carbon, creating biomass. Algae may remove CO2 from raw biogas. Biomethane/biogas 1 and/or CO2 can be injected into a gas dissolver 2 containing algae. The liquid (containing algae) can be saturated with carbon dioxide, and held in an absorption tank 4, before entering digester 5. Methane may be vented. Light in the digester 5 can allow the microalgae in the liquid to grow, digesting the carbon dioxide, forming biomass. Recycled liquid can be fed back into the gas dissolver 2. Harvested biomass from the outlet 6 can be used for biofuel production. The gas absorber 2 may have a rotating cylinder within a sealed tube (figure 2), creating high shear in the gas and liquid mixture, increasing gas/algae interaction. A second gas dissolver may be used to remove more carbon dioxide. Output may include protein and lipids. The liquid may be water.
Description
TREATMENT OF CARBON DIOXIDE CONTAINING MATERIALS WITH ALGAE
Previous laboratory and pilot studies have demonstrated the prospect of using algae for capturing greenhouse gas. However, the incumbent processing methodologies rely on sparging, a method that has proven inefficient due to severe gas escape. Sparging delivers a relatively low concentration of dissolved carbon to the algae and thereby poor growth yields are experienced. We have found that the concentration can be increased particularly by using a bioreactor such as the one developed by Autichem Ltd, as described in GB patent applications 2545924 and GB2545927. Additionally, by increasing the efficiency of delivery of CO2 to algae the amount of light energy required to fix the carbon is also reduced.
Algae is capable of sequestering CO2 and have higher CO2 biofixation than terrestrial plants. Algae can fix CO2 through photosynthesis to produce carbohydrate, lipids and other valuable products.
Algae are a ubiquitous group of photosynthetic organisms and are found in the ocean, freshwater bodies, on rock, soils and on vegetation. Their simple cellular structure makes them efficient converters of solar energy and fixes carbon dioxide and producing approximately half of the global atmospheric oxygen.
Algae can grow in wastewater and perform a triple role of wastewater remediation, biomass production and carbon capturing. The biomass from the algae can be used to produce products including biofuel, biofertilizer and palm oil alternatives.
The addition of CO2 gas to algae growing in wastewater can provide extra carbon source and consequentially increase the nutrient removal efficiency from the wastewater.
A dynamic mixed flow reactor such as that developed by Autichem Ltd provides an efficient means of dissolution of gases in aqueous medium. The system uses a tubular and rotating component to create and breaks bubbles for effective adsorption of gas in liquid. The reactor can be used to dynamically mix CO2 gas continuously with algae culture and thereby increasing the retention time of CO2 in the culture and enabling capture of larger amounts of the 002. Further reaction stages allow the algae to assimilate the dissolved CO2 and allow recovery/conversion.
Improved carbon capture and bioqas treatment process In one embodiment the invention provides more efficient mixing of liquid and or gases containing sources of carbon and microalgae. The improved mixing in the system enables the microalgae to sequestrate any carbon with increased productivity. The biomass produced by this system is suitable for conversion to a range of other valuable products.
An alternative embodiment of the invention allows the use of algae for removing CO2 from raw Biogas. Biogases include, but are not limited to, Bio-methane and Bio-hydrogen. In this instance the systems produces upgraded Biogas and can provide a biomass suitable for conversion to a range of other valuable products.
Raw Bio-methane is primarily a mixture of methane (CH4) and inert carbonic gas (CO2). The presence of 002, water and H2S make biogas very corrosive and requires the use of expensive resistant materials leading to high equipment costs. The composition of a gas produced from a digester depends on the substrate, on its organic matter load and on the feeding rate of the digester. This variability in product composition and the relatively poor calorific value means that the use of biogas for combustion is not always a good economic option without additional processing and expense. However the upgrading of the biogas by removal of the more soluble CO2 by algae according to this invention generates new possibilities for its use since it can then replace natural gas, which is used extensively in many countries. This invention therefore provides an optimized upgrading process in terms of low energy consumption and high efficiency giving high methane content in the upgraded gas. The invention further provides a continuous multistage bioprocess, that increases the efficiency of delivering CO2 to algae with no gas escape and thereby providing a pathway for the commercial implementation of CO2 capturing using algae. An additional feature is the ability to remove CO2 from the waste gas.
Accordingly in one embodiment this invention provides a method and equipment to convert biogas into a more useful fuel. Furthermore this provides a method and equipment for converting CO2 into a useful fuel. The product of the process is a fuel in the form of combustible gas or a combustible liquid or both.
The present invention is illustrated by the accompanying Figures in which Figure 1 is a schematic diagram of a process and apparatus according to the present invention.
Figure 2 is an illustration of the gas dissolver used in the apparatus of Figure 1.
Figure 3A compares the composition of an influent biomethane stream to the apparatus of Figure 1 and composition of output of the apparatus.
Figure 33 compares the specific energy in the influent and effluent streams of Figure 3A.
Figure 1 shows a schematic of a process according to one embodiment of the invention. Gas (1) is injected into a gas dissolver (2). The gas is biogas. Algae are provided in the gas dissolver (2). Gas in the form of CO2 can also be injected as an alternative to the biogas. In most cases both biogas and CO2 will be injected together or at different stages. A fluid is injected into the gas dissolver (7) which operates on a recycle loop. Gas, liquid and algae pass through the gas dissolver (2) in a flow pattern which is substantially plug flow. The algae containing liquid discharging from the gas dissolver is saturated with CO2 and is held in the absorption tank (4). Excess gas passes to a vent line (3). The high concentration of CO2 in the absorption tank (4) ensures that the CO2 is absorbed into the live microalgae where the feed is bio-methane, the methane from which the CO2 has been removed may be vented at line 3 and may be used for fuel purposes. Fluid passes from the absorption tank to a digester (5). The lower concentration of CO2 in the digester (5) combined with a light source allows the microalgae to grow and in doing so digest the CO2 to form biomass. The source of light may be natural light or artificial light. CO2 is replenished by recycling fluid through the gas dissolver into which CO2 and or Biogas is added. The biomass is harvested from the outlet (6) and may be used for the production of biofuels and other products.
The process described above may be operated in batch or continuous mode. Chemical addition or treatment may also be added to maintain the right conditions for microalgae growth. This includes but is not exclusive to materials or methods to control pH, nutrient addition, neutralisation or removal of harmful materials or removal of particulates.
Patents GB2545927 and GB2545924 describe a novel continuous reactor which may be used as the gas absorber (2) used in this invention. Figure 2 shows the key elements of the reactor which comprises a sealed tube (9) with a gas feed connection (8), a liquid feed connection (12) and a discharge connection (11). The gas feed (8) and liquid feed (12) connections may be combined into a single connection. A mixing element (10) in the form of a rotating cylinder is located within the sealed tube (9). The rotational movement of element (10) is generated by a drive system (13). The drive system may be an external motor or hydraulic or pneumatic drive connected to the mixing element by a shaft. A mechanical seal or magnetic coupling may be used to keep the system sealed. Alternatively a magnetic drive system may be used.
The rotating mixer (10) creates an annual space between the mixer and the reactor wall and exposes the gas and liquid mixture to high shear which increases the interaction between the gas and the algae. The high shear creates a high interfacial area between the gas and the algae containing liquid and also reduces boundary layer resistance.
The gas discharge from the absorption vessel may also pass through a second gas dissolver 10 to remove 002.
Example
A stream of carbon dioxide was passed through the apparatus shown in Figure 1 and the algae growth parameter was compared with a run in which the stream was biomethane of content roughly 40% methane and 60% carbon dioxide and the results were as follows.
Biomethane CO2 Carbon Biofixation rate (g L-1 day -1) 0.991 ± 0.227 1.057 ± 0.192 Biomass Productivity (g L d -1) 0.462 ± 0.028 0.481 ± 0.038 Algae Growth rate (d -1) 0.368 ± 0.037 0.422 ± 0.052
