Definitions
- the present invention relates to a method and a plant for purifying a feed gas stream comprising at least 90% CO 2, preferably 95% CO 2.
- Carbon dioxide is used in various applications, for example for the food market, which requires that CO2 contain very low levels of impurities.
- the International Society of Beverage Technologists (ISBT) requires the following composition:
- Oxygen 30 ppm v / v max.
- Carbon monoxide 10 ppm v / v max.
- Non-volatile residue 10 ppm w / w max.
- Nonvolatile organic residue 5 ppm w / w max.
- Total volatile hydrocarbons (such as methane) 50 ppm v / v max. with 20 ppm v / v max. for total non-methane hydrocarbons
- Acetaldehyde 0.2 ppm v / v max.
- the CO2-rich feed stream can come from a variety of sources, such as ammonia plants, natural wells, bio-fermentation, syngas production units, and the like. ... containing various traces of impurities, including hydrocarbons, sulfur compounds, nitrous compounds, chlorinated compounds and many other impurities which must be efficiently and economically removed.
- Catox catalytic oxidation
- the wet separator is a common solution that can be adapted to high levels of impurities. It consists of passing the feed gas through a medium promoting fluidic contact, for example a structured or random packaging, inside a container. Water is sprayed or dispensed onto the top of the container. If this solution seems effective in removing water-soluble hydrocarbon-containing hydrocarbons such as, for example, ethanol and methanol from feed streams, it is not effective in removing hydrocarbons that are not soluble in water. water, whose solubility in water is very low. Another disadvantage is that water must be introduced into the system. For the food-grade CO2 production area, this water must consume drinking water. Such water may not be available or at a high cost in an industrial plant.
- the basic anions of the hydroxyl group, carbonate or bicarbonate are introduced in a solid (milled) or liquid form into the feed gas.
- Basic anions react with acid gases to form salts.
- the salts are then filtered in a bag filter or separated in a container.
- the disadvantage of this solution is that it is not referenced for high efficiency removal. Its classic application is the treatment of flue gases, in order to comply with environmental standards. These standards are much less demanding than those applied for food C0 2 .
- this solution involves the addition of an external component.
- Handling chemical reagent such as sodium hydroxide requires special care and additional equipment (storage, dosing system).
- storage, dosing system For example, the use of sodium bicarbonate entails strong constraints. Indeed, this solution must be used at a temperature between 140 ° C and 300 ° C.
- Adsorption beds may be based on physical adsorption.
- the low adsorption force implies easy regeneration, but also fairly low or moderate adsorption capacities.
- it allows a regenerative process, having a long life, on the other hand, it may require high amounts of adsorbents detrimental to the cost or very fast cycle times (time including adsorption then the regeneration steps) implying that large amounts of regeneration gas are available.
- a problem is to provide an improved and economical method of purifying a feed gas stream comprising at least 90% CO 2.
- a solution of the present invention is a process for purifying a feed gas stream comprising at least 90% CO2, preferably at least 95% CO 2, at least 20% relative humidity and at least one impurity selected from chlorinated, sulfur-containing, nitrated or fluorinated compounds comprising the following successive steps:
- step c) a step of removing at least a portion of the acid impurities by contacting the gas stream from step b) in contact with at least one corrosion-resistant heat exchanger so as to condense the acidic compounds while regulating the temperature of the gas stream leaving under the dew point of the water;
- step d) a step of separating the acidic compounds of the gas stream from step c) by means of a corrosion-resistant separator so as to produce a gas stream enriched with CO2.
- Step b) avoids any creation of acidic liquid which corrodes the piping and other standard materials. It will be ensured never to pass below the critical dew point via suitable operating conditions but also thanks to a thermal insulation or even an external temperature maintenance system (electric or steam) preventing the creation of cold spots (temperature locally below the critical dew point) on the equipment.

- 254SMO and 904L steels nickel-based alloys or titanium.
- the heat exchanger is made of 254 SMO stainless steel for the parts in contact with the process gas, the rest being SS 316L steel, specially designed for strong corrosion created by the Hcl.
- the catalytic oxidation is carried out by means of a sulfur and chlorine-resistant catalytic oxidation unit.
- the stream is contacted with a catalyst bed containing a first layer of platinum catalyst and a second layer of palladium catalyst, making it possible to convert most of the hydrocarbons into water and carbon dioxide.
- a catalyst bed containing a first layer of platinum catalyst and a second layer of palladium catalyst, making it possible to convert most of the hydrocarbons into water and carbon dioxide.
- the gaseous flow at a temperature above 300 ° C. and containing HCl is cooled to a temperature above the dew point of the water (43 ° C.), in order to prevent condensation.
- the fluid at a temperature of 55 ° C., will then be fed into a skid comprising a heat exchanger made of a material resistant to chloridic acid, such as steel grade 254SMO.
- the cold will be brought into the exchanger through a coolant such as water, at a temperature below 43 ° C, preferably below 10 ° C to minimize the size of the exchanger. Cooling water supplying the exchanger
- the separation of the liquid droplets containing the acid molecules will be ensured by a separator pot (installed directly downstream of the exchanger) in a material resistant to corrosion by chlorine such as steel grade 254 SMO or more simply by a material made of polymer resin.
- the process gas leaving the separator pot and the condensed liquid, purged at the bottom of the separator pot will have the following compositions:
- AcetAldehyde 0.000000 0.000000
