    • The present invention relates to a process, and relevant plant (1), for separating at least one key component (KC) from a multicomponent gas stream (GS) that is caused to flow on a composite membrane (20) comprising dense domains (21) permeable to the key component (KC) and porous domains (22) intended to adsorb preferentially the key component (KC). A permeate stream (PS), separated from the multicomponent gas stream (GS) and containing the key component (KC), is extracted through a discharge line (5) depending on the measured value of the pressure (P) downstream the membrane (20), Upon reaching a predetermined maximum value (p max ) of such pressure (P), the permeate stream (PS) is extracted until reaching a predetermined minimum value (p min ) of such pressure (P) downstream the membrane (20), and upon reaching such predetermined minimum value (p min ), the extraction of the permeate stream (PS) is stopped. Thus by repeating such operations extracting and stopping the extraction downstream the membrane (20), alternated cycles are generated and a pseudo-steady state condition is accomplished, where the plant (1) receives the feed stream (GS) in the continuous mode and releases the permeate stream (PS) in an intermittent manner, while a retentate stream (RS), containing the components of the feed stream (GS) that have not been collected in the permeate stream (PS) is discharged with continuity. By handling the predetermined maximum value (p max ) and minimum value (p min ) of the pressure (P) downstream the membrane (20), that is of the extraction cycle of the permeate stream (PS), it is possible to considerably vary the efficacious permeance value and the separation factor of the process without modifying the membrane (20), the module (10) where it is contained or the feeding conditions.
    • 本发明涉及用于将至少一种关键成分(KC)与多组分气流(GS)分离的方法和相关设备(1),所述多组分气流(GS)在包含致密结构域的复合膜(20)上流动 )可透过关键组分(KC)和多孔区域(22),其旨在优先吸附关键组分(KC)。 根据膜下游的压力(P)的测量值(20),从多组分气流(GS)分离并含有关键组分(KC)的渗透物流(PS)通过排出管线(5)提取 )当达到这样的压力(P)的预定最大值(pmax)时,提取渗透物流(PS)直到达到膜(20)下游的压力(P)的预定最小值(pmin),并且在 达到这样的预定最小值(pmin)时,停止提取渗透物流(PS)。 因此,通过重复这样的操作来提取和停止在膜(20)下游的提取,产生交替循环并且完成伪稳态条件,其中工厂(1)以连续模式接收进料流(GS)并释放 间歇性地渗透物流(PS),而含有未被收集在渗透物流(PS)中的进料流(GS)的组分的滞留物流(RS))连续排出。 通过处理膜(20)下游(即渗透物流(PS)的萃取循环)下游的压力(P)的预定最大值(pmax)和最小值(pmin),可以显着地改变有效 渗透值和分离因子,而不改变膜(20),包含的模块(10)或进料条件。
