Abstract: A liquid distribution assembly includes a plate to collect liquid and a plurality of liquid distributors coupled to the plate. Each liquid distributor of the plurality of liquid distributors includes a conduit extending down from the plate. Liquid is to flow internal to the conduit from the plate. Each liquid distributor also includes a dome coupled to the conduit at an end of the conduit distal from the plate. The conduit defines openings disposed where the dome is coupled to the conduit permitting the liquid to flow from the conduit to the dome. The liquid is to flow over an edge of the dome.

Abstract: A separation system includes a column including a stripping section proximal to a lower end of the column, a rectifying section proximal to an upper end of the column, and an intermediate section disposed between the stripping section and the rectifying section. The intermediate section includes first and second vertical sides separated by a vertical wall. The column includes a feed port to receive a material stream to be separated. The separation system further includes a reboiler in fluid communication with the column. The reboiler provides vapor to the stripping section. The separation system also includes a condenser in fluid communication with the column. The condenser provides liquid to the rectifying section, the condenser to provide a distillate effluent stream. The separation system further includes an active vapor control to control the relative vapor flow rate to the first and second sections.

Abstract: An exchange device includes a plate having a top surface, a bottom surface, a plurality of openings extending between the top and bottom surfaces. The top surface receives a liquid which flows in a flow direction over the top surface. A plurality of valves is disposed over the openings. Each valve includes a round lid coupled to the first, second, and third legs. The first leg is upstream of the second and third legs relative to the flow direction. The first leg has a width that is greater than the width of the second and third legs. In particular, a ratio of the width of the first leg to the width of the second leg is in a range of 1.6:1 to 2.6:1.

Abstract: A separation system can include one or more vapor-liquid contact trays. A vapor-liquid contact tray can include a set of panels. Two adjacent panels can be connected at a joint at overlapping edges of the panels. The first panel can include slots extending through the first panel proximal to a first offset bend. Tabs of the first panel can extend downward toward an underside of the first panel. The tabs can originate from an edge of the slots proximal to the deck and extend downward relative to a horizontal plane of the deck. The second panel can include a plurality of strips that have a second offset bend extending from a deck of the second panel extending through a slot and to underlie the first panel. A strip of the plurality of strips can define an opening through which a tab of the first panel can extend.
