    Abstract: The present invention are methods for removing preselected substances from a mixed flue gas stream characterized by cooling said mixed flue gas by direct contact with a quench liquid to condense at least one preselected substance and form a cooled flue gas without substantial ice formation on a heat exchanger. After cooling additional process methods utilizing a cryogenic approach and physical concentration and separation or pressurization and sorbent capture may be utilized to selectively remove these materials from the mixed flue gas resulting in a clean flue gas.

    Abstract translation: 本发明是从混合烟道气流中除去预选物质的方法,其特征在于通过与骤冷液体直接接触来冷却所述混合烟道气,以冷凝至少一种预选物质并形成冷却的烟道气,而不会在热交换器上形成大量的冰 。 在冷却后,使用低温方法和物理浓度和分离或加压和吸附剂捕获的附加工艺方法可用于从混合烟道气中选择性地除去这些材料,从而产生干净的烟道气。
