Title (EN) SEPARATING ETHANE FROM METHANE
(FR) SEPARATION DE L'ETHANE DU METHANE
Abstract: front page image
(EN)Ethane is separated from methane by passing a gaseous mixture of the ethane and the methane (plus a carrier gas if desired, e.g. helium, which can be 95% of the total volume) at a temperature from 150K to 400K and at a pressure from 1 to 80 bar through a bed of an adsorber having an effective molecular sieve size from 4(Alpha) to 10(Alpha) until the methane concentration per unit volume of gas leaving the bed is at least as great as the methane concentration per unit volume of the mixture passing into the bed (at the same pressure), discontinuing the passage of the mixture (but optionally allowing any carrier gas to continue to flow) and collecting the gas which is released from the bed next after a complete cessation of methane release. That gas is relatively enriched in ethane, often containing only ethane (plus any carrier gas).
(FR)On separe l'ethane du methane en faisant passer un melange gazeux d'ethane et de methane (plus un gaz porteur si on le desire, p. ex. de l'helium, qui peut representer 95% du volume total) a une temperature se situant entre 150K et 400K et a une pression de 1 a 80 bars au travers d'un lit adsorbant ayant une dimension de tamis moleculaire effective de 4 66 a 10 66 jusqu'a ce que la concentration de methane par unite de volume de gaz quittant le lit soit au moins aussi grande que la concentration de methane par unite de volume du melange passant dans le lit (a la meme pression), en arretant le passage du melange (mais eventuellement en laissant du gaz porteur de continuer de s'ecouler), et en recuperant le gaz qui se degage du lit juste apres un arret complet de degagement de methane. Ce gaz est relativement riche en ethane, ne contenant souvent que de l'ethane (plus un gaz porteur).
