“…One used method that is dependent on pressure variables is Pressure Swing Adsorption (PSA). PSA is one of the adsorption methods with high pressure operated and when a fluid flow through it, some component will be adsorbed because of high pressure [4]. For the liquid light naphtha used in this study, the properties are itemized in Table 1.…”

“…Several studies and studies relevant to PSA on upgrading chemical commodities including naphtha have been carried out several times. Chang et al studied the influence of adsorber models and studies related to the influence of operating specifications on adsorption performance [4]. Dobladez et al studied an external influence in the form of the influence of the type of adsorbent used on adsorption performance [5].…”

Light naphtha is an organic compound produced from the distillation process that is often sold at a low price because of its poor performance, especially in the value of Research Octane Number (RON). The goal of this study was to improve the quality of naphtha to become a useful fuel with qualifying performance that is High Optimum Mogas Component (HOMC) by using the Pressure Swing Adsorption (PSA) method with the help of Aspen Adsorption simulations to find the most optimal combination of zeolite adsorbents (Beta and 5A) to use in the process. The principle of this quality improvement is to separate the compounds contained in naphtha that have low RON values from those that have high RON values so that the performance of naphtha that has gone through the adsorption process can be maximized. For this study, the RON target from HOMC is 95, while the value of RON for feed light naphtha ranges from 61-65. There are three compounds simulated in this PSA process, n-pentane and n-hexane as compounds that want to be separated because they have low RON values from iso-pentane which has a high RON value. Furthermore, after acquiring the combination of adsorbents that resulted in the products that have the highest RON, the economic potential of all variables was evaluated to get the most optimal process to use. The economic potential is also analyzed to find the profit of the PSA process. The most optimal results are obtained when the adsorbent configuration produces the product with the highest RON and produces high economic potential. The results showed that the most optimal adsorbent combination is to use 30% Zeolite Beta; 70% Zeolite 5A with product results having the highest RON of 84 and economic potential of US$ 114,410,163.92.

“…La composición del gas natural, se conoce por medio de lo dispuesto por Vanti (2020), quien es el distribuidor que lleva el combustible a planta, los cuales muestran la composición del mismo y que se presenta en la Tabla 4-12, mostrando únicamente los componentes con una participación mayor de 1% en el combustible. La composición del aire atmosférico se toma según lo mencionado por Chang et al (2021), en donde se tiene una composición mayoritaria de nitrógeno y oxígeno en la atmósfera, y cuyos porcentajes se presentan en la Tabla 4-13. La composición de los gases de salida de la caldera, se toman del estudio más reciente de la planta de análisis, sobre sus emisiones atmosféricas, cuyos valores se presentan en la Tabla 4-14, en donde es posible evidenciar que la suma de los componentes no resulta en 100%, y para ello se usa lo mencionado por Moran et al (2014), donde el porcentaje restante es nitrógeno.…”

“…Now it has evolved an ideal separation method with high automation, low cost, and on-site gas production capability [4]. Air was separated by the difference in the loading of O 2 and N 2 adsorbed in the zeolite, and oxygen with a purity of over 90% was enriched by cyclic pressure changes [5].…”

To enhance the oxygen guarantee capacity in high altitude areas and address the challenges of traditional pressure swing adsorption oxygen generation fixed equipment with large volume and multiple device modules, a novel single-reversible-pump single-bed vacuum pressure swing adsorption (VPSA) oxygen generation process was proposed and simulated. This study investigated the effects of purge on oxygen productivity, purity, recovery, and energy consumption, determining that the optimum ratio of total oxygen in the purge gas to the total oxygen in the feed gas (P/F) was 0.176. A set of principle prototypes was developed and validated in plains. The process performance was then simulated and studied at altitudes of 3000 m, 4000 m, and 5000 m. Finally, the optimization was carried out by adjusting the product flow rate and feed flow rate, revealing that the best performance can be achieved when the oxygen purity exceeded 90% with lower energy consumption or larger productivity than the optimization goal. This study serves as a valuable reference for the optimization of the VPSA oxygen generation process in a plateau environment.
