    Abstract: A continuous vacuum distillation system for separating one or more components of a multi-component composition by distillation, including a plurality of distillation columns, including a stripping column and a rectification column, wherein at least some of the distillation columns are configured according to an indirect split arrangement of coupled sections. In some embodiments, a near steady-state pressure condition operating range of 15 mmHg to 85 mmHg is obtained, with an operating temperature of less than 100° F., where the a near steady-state condition includes a nearly unchanged pressure condition across multiple stages. In some embodiments, processing across all stages occurs as a closed system.

    Abstract: An alkanolamine gas treatment unit system that may comprise an absorber column, a regenerator column, and a once-through natural circulation vertical thermosyphon reboiler comprising a reboiler tube and a shell. The reboiler may be a steam driven one having a process side and a shell side, wherein the process side is inside the reboiler tube, the process side of the reboiler and the regenerator column are in fluid communication with one another, an inner surface of the reboiler tube, on the process side, has a surface roughness of 0.06 µm or greater, the shell side of the reboiler is in fluid communication to a steam source, and the regenerator column and the absorber column are in fluid communication with one another. An absorbent regenerator system that may comprise the regenerator column and the once-through natural circulation vertical thermosyphon reboiler.

    Abstract: An energy saving and emission reduction system for chemical separation and purification process is disclosed. The chemical separation and purification process includes a synthesis section and/or a distillation section and/or a recovery section. The energy saving and emission reduction system includes an energy comprehensive utilization maximizing energy saving module. The energy comprehensive utilization maximizing energy saving module comprehensively evaluates the chemical separation and purification process, and acquires a lowest energy consumption value according to initial and final material flow parameters. Then energy integration optimization and energy saving technical modification are performed on the synthesis section and/or distillation section and/or recovery section according to the lowest energy consumption value. The disclosure involves a comprehensive and extensive energy saving and emission reduction system for chemical separation and purification process, and has achieved good environmental benefits.

    Abstract: A distillation system and process for separating a multi-component feed mixture in a distillation system comprising a first distillation column having a first fired reboiler, and at least a second distillation column having a second heat-exchange reboiler, comprising the steps of a) introducing the feed mixture to the first column, and separating into at least a first top and a first bottom product; b) taking part of the first bottom product for providing heat to the second reboiler as a utility stream; and c) feeding part of said utility stream after heat-exchange as main feed to the second column for further separation. This process allows significant energy savings, by reduction of the amount of external heat required for the fired reboiler and omission of a conventionally used heat-exchanger.

    Abstract translation: 一种用于在蒸馏系统中分离多组分进料混合物的蒸馏系统和方法，所述蒸馏系统包括具有第一次再沸器的第一蒸馏塔和具有第二热交换再沸器的至少第二蒸馏塔，所述第二蒸馏塔包括以下步骤：a）引入 进料混合物至第一塔，并分离成至少第一顶部和第一底部产物; b）将第一底部产物的一部分作为效用流提供给第二再沸器的热量; 和c）在热交换之后将所述有用物流的一部分作为主进料送入第二塔用于进一步分离。 该方法通过减少烧制再沸器所需的外部热量和省去常规使用的热交换器，可显着节省能源。
