| description | In natural gas plants, the carbon dioxide (CO2) traveling in the extracted stream is separated and released to the atmosphere. This stream also contains hydrogen sulfide (H2S), water and hydrocarbons. The
purpose of this investigation was to design a process to purify this CO2 stream, to its further use in the
food industry. There, the CO2 can be employed in carbonated drinks and as supercritical fluid; requiring
a purity higher than 99.95 mol%. Therefore, a real flow of 3454 ton/year CO2 was selected as case of study, which is emitted in a gas treatment plant located in Neiva, Colombia. This stream was simulated in ProMax and subjected to chemical absorption with methyl diethanolamine (MDEA), to a dehydration with diethylene glycol combined with molécular sieve, to a Ryan-Holmes cryogenic process for removing light components (methane and ethane) and their combinations. The combination of the three processes allowed us for a 99.95% CO2
recovery and a 99.99 mol% CO2 purity, requiring capital expenses (CAPEX) of USD 412.323 or 53 USD/tCO2. This CO2 could be commercialized at sell prices as high as 5000 USD/tCO2 to the food industry. In addition, the combination of the two first processes delivered a CAPEX of 37 USD/tCO2 with a 99.85 mol% CO2 purity, suitable for other applications requiring less purity in the food industry or improved oil recovery. |

En las plantas de extracción de gas natural (GN), el dióxido de carbono (CO2) que viaja en la corriente extraída se separa y se libera a la atmósfera, acompañado de ácido sulfídrico (H2S), agua e hidrocarburos. El objetivo de esta investigación fue diseñar un proceso para purificar esta corriente de CO2, para su posterior uso en la industria alimenticia, donde el CO2 se puede usar en bebidas carbonatadas y como fluido supercrítico; requiriendo una pureza superior a 99,95% mol. Para ello, se seleccionó como caso de estudio un flujo real de 3454 ton/año de CO2 emitido por una planta de gas natural localizada en Neiva, Colombia y se simuló en ProMax. Se simularon la absorción química con metildietanolamina (MDEA), deshidratación con trietilenglicol (TEG) combinada con tamiz molecular, procesos criogénicos de Ryan Holmes y sus combinaciones. La combinación de los tres procesos permitió una recuperación de 99,95% de CO2 con una pureza del 99,99 %mol, requiriendo una inversión total de USD 412.323 o 53 USD/tCO2. Esta CO2 podría ser comercializado a valores superiores a 5000 USD/tCO2 para la industria alimenticia. Además, la combinación de los dos primeros procesos arrojó costos de 37 USD/tCO2, produciendo una pureza de CO2 de 99,85 %mol apto para otras aplicaciones.
