A method for treating, using temperature swing adsorption, a hydrocarbon mixture containing hydrocarbons with less than five carbon atoms and heavier hydrocarbons including hydrocarbons with five and/or six carbon atoms and hydrocarbons with at least seven carbon atoms is provided, the method comprising forming a process stream from at least a part of said hydrocarbon mixture and passing said process stream through an adsorption vessel, the adsorption vessel comprising, a first adsorbent or adsorbent layer and a second adsorbent or adsorbent layer, wherein the first adsorbent or adsorbent layer and the second adsorbent or adsorbent layer are configured such that the first adsorbent or adsorbent layer adsorbs at least a major proportion of the hydrocarbons with at least seven carbon atoms from a given amount of the process stream passed trough the adsorption vessel during an adsorption time period and the second adsorbent or adsorbent layer.
A method for treating, using temperature swing adsorption, a hydrocarbon mixture containing hydrocarbons with less than five carbon atoms and heavier hydrocarbons including hydrocarbons with five and/or six carbon atoms and hydrocarbons with at least seven carbon atoms, the method comprising forming a process stream from at least a part of said hydrocarbon mixture and passing said process stream through an adsorption vessel, the adsorption vessel comprising, in a first adsorption zone, a first adsorbent or adsorbent layer and, in a second adsorption zone downstream of said first adsorption zone, a second adsorbent or adsorbent layer, wherein the first adsorbent or adsorbent layer and the second adsorbent or adsorbent layer are configured such that the first adsorbent or adsorbent layer adsorbs at least a major proportion of the hydrocarbons with at least seven carbon atoms from a given amount of the process stream passed through the adsorption vessel during an adsorption time period and the second adsorbent or adsorbent layer adsorbs at least a major proportion of the hydrocarbons with five and/or six carbon atoms from the given amount of the process stream passed through the adsorption vessel during the adsorption time period, and wherein the process stream is, while being passed through the adsorption vessel, initially depleted in the hydrocarbons with at least seven carbon atoms and not depleted, or depleted to a smaller extent, in the hydrocarbons with five and/or six carbon atoms in the first adsorption zone of the adsorption vessel and then depleted or further depleted in the hydrocarbons with five and/or six carbon atoms in the second adsorption zone of the adsorption vessel.
An arrangement for treating, using temperature swing adsorption, a hydrocarbon mixture containing hydrocarbons with less than five carbon atoms and heavier hydrocarbons including hydrocarbons with five and/or six carbon atoms and hydrocarbons with at least seven carbon atoms, said arrangement comprising an adsorption vessel and means configured to form a process stream from at least a part of said hydrocarbon mixture and to pass said process stream through the adsorption vessel, the adsorption vessel comprising, in a first adsorption zone, a first adsorbent or adsorbent layer and, in a second adsorption zone downstream of said first adsorption zone, a second adsorbent or adsorbent layer, wherein the first adsorbent or adsorbent layer and the second adsorbent or adsorbent layer are configured such that the first adsorbent or adsorbent layer adsorbs at least a major proportion of the hydrocarbons with at least seven carbon atoms from a given amount of the process stream passed through the adsorption vessel during an adsorption time period and the second adsorbent or adsorbent layer adsorbs at least a major proportion of the hydrocarbons with five and/or six carbon atoms from the given amount of the process stream passed through the adsorption vessel during the adsorption time period, such that the process stream is, while being passed through the adsorption vessel, initially depleted in the hydrocarbons with at least seven carbon atoms and not depleted, or depleted to a smaller extent, in the hydrocarbons with five and/or six carbon atoms in the first adsorption zone of the adsorption vessel and then depleted or further depleted in the hydrocarbons with five and/or six carbon atoms in the second adsorption zone of the adsorption vessel.
