20100219060 | Mass-exchange contact device - A mass-exchange contact device is proposed, comprising upper and lower flat ring-shaped trays attached to a column, a sleeve having windows with bottom edges in the plane of the lower tray, a barbotage unit having orifices in its sidewalls placed on the top sleeve, a movable double-acting valve including upper and lower plates connected with a rod. The barbotage unit includes an ascending limiter of valve's movement, the sleeve's bottom includes a descending limiter. Alternatively, the barbotage unit is made as a portion of the sleeve. Embodiments comprise a number of rows of the proposed devices situated one above the other, and separated by multi-layer packing fittings. The devices can be used in catalytic distillation columns, wherein the fittings are filled with catalytic material. Alternatively, the fitting is substituted with a grating supporting a catalytic granular layer. The proposed design improves device operation, reliability, durability, reduces its weight and costs. | 09-02-2010 |
20100221156 | Mass exchange contact device - A mass-exchange contact device is proposed, comprising an upper tray, contact element including a barbotage unit configured as an inner cap with strips tangently bent out, a lower tray, a casing including a ring-shaped descending limiter, windows circumferentially disposed on the casing's walls (lower row), orifices circumferentially disposed on the casing's walls (upper row) above the windows, a double-acting valve composed of an upper and lower plates fixedly attached to a distance rod, and a cover bushing disposed coaxially to and around the upper region of casing embracing the contact element. Embodiments comprise a number of rows of the proposed devices situated one above the other, and separated by multi-layer packing fittings. In catalytic distillation columns, the fittings can be filled with catalytic material. Alternatively, the fitting is substituted with a grating that supports a catalytic granular layer. The device allows improving operation, reliability, durability, reducing its weight and costs. | 09-02-2010 |

20090200690 | Mass Transfer Device - A mass-exchange contact device is proposed, comprising: upper and lower flat ring-shaped trays outwardly attached to a column, a sleeve including sidewalls attached to the trays and having windows made therein with bottom edges in the plane of the lower tray, a barbotage unit connected to the top of sleeve and having orifices in its sidewalls, a movable double-acting valve including two upper and lower plates attached to a rod axially disposed therebetween. The top of barbotage unit includes an ascending limiter of valve's movement, the bottom of sleeve includes a descending limiter of the valve's movement. In some embodiments, the barbotage unit is made as a portion of the sleeve. The height of windows preferably is equal to the height of valve. The proposed design significantly improves device operation for a cyclic mode, reliability, durability, reduces its weight and cost, extends its operational range for steam and liquid loads. | 08-13-2009 |

20090145738 | Mass Exchange Contact Device - A mass-exchange contact device is proposed, comprising: upper and lower trays, a contact element including a barbotage unit, a cylindrical casing including windows circumferentially disposed thereon and orifices circumferentially disposed above the windows, a movable valve including two solid plates one above the other and attached to a distance rod, and a cover bushing disposed around the upper region of casing. The contact element restricts the valve's upward movement, the casing's bottom edge restricts the valve's downward movement, the bottom edges of the windows are disposed at the level of lower tray, and the exterior of contact element communicates with the interior of casing via the inner space of the bushing and the orifices. In some embodiments, the windows and orifices are united in continuous openings. The device significantly improves operation especially for a cyclic mode, reliability, and durability. | 06-11-2009 |
