A tower packing element (100), a tower packing (300), a packing tower, and a mixer including the tower packing element (100) are provided. The tower packing element (100) is manufactured by a deformed plate and includes a plurality of strip assemblies (10) arranged along a longitudinal direction of the tower packing element (100) and a connecting plate portion (20) connected between adjacent strip assemblies (10). Each of the strip assemblies (10) defines a central passage (30) therein, and the central passage (30) is extended in a lateral direction of the tower packing element (100). The connecting plate portion (20) is extended along the lateral direction of the tower packing element (100). The adjacent strip assemblies (10) and the connecting plate portion (20) connected therebetween define a side passage (40) parallel to the central passage (30).

A process for forming and for catalytically converting an ignitable gas mixture is proposed, in which at least a first gas or gas mixture comprising oxygen and a second gas or gas mixture comprising one or more oxidizable compounds are mixed to give the ignitable gas mixture, where the ignitable gas mixture is supplied to a reaction zone (12) of a reactor (1). The first gas or gas mixture and the second gas or gas mixture are fed into a mixing chamber (11) having a boundary wall (13) provided with a number of passages (131), where the first gas or gas mixture is fed into the mixing chamber (11) through the passages (131) in the boundary wall (13) and where the second gas or gas mixture is fed into the mixing chamber (11) by means of one or more feed conduits (14) which have feed orifices (141) and extend into the mixing chamber (11). The present invention likewise provides a corresponding reactor (1).

The present invention discloses an efficient mass-transfer separation bulk filler structure, which includes a bulk filler body with closely-fit multilayer structures, wherein an annular wall surface of the bulk, filler body has a corrugated angle group. A lower portion of the bulk filler body is of a bell-mouth shape. Three passages with a same sectional area are formed inside the bulk filler body. The present invention has the characteristics of small pressure drop, large specific surface area, low liquid holdup and large void ratio. The annular wall surface is provided with the corrugated angle group to increase the disturbance and reduce a double-membrane thickness of vapor and liquid phase mass-transfer resistance, thereby improving the mass-transfer coefficient and separation efficiency. Meanwhile, by adopting the bell-mouth shape, the stability and natural stacking regularity of the bulk filler can be improved.

The invention is a tray 2 for a column for heat and/or matter exchange between a gas and a liquid, comprising at least one chimney 4 projecting from the upper part of tray 2 for exclusive passage of the gas through the tray, at least one means 5 enabling passage of the liquid through tray 2 and the inside of at least one of the chimneys providing exclusive gas passage being provided with a material dispersive towards said gas. The invention also relates to an exchange column comprising such a distributor tray and to the use of such a column.

It has been discovered that the efficiency of asphalt blow stills (reactor columns) can be improved by filling the blow still with various types of packing material, such as metal or glass spheres (or other rigid materials). The packing material acts to reduce air bubble size and improve the dispersion of the air bubbles throughout the asphalt. This increases the total surface area per unit volume of the air bubbles and promotes a faster processing time. The packing material also increases the contact time between the air bubbles and the asphalt which further results in improved efficiency and reduced blow times. This is beneficial because faster processing times can be achieved resulting in more efficient use of equipment, higher levels of productivity, lower energy requirements, cost savings, reduced blow loss, and reduced thermal history to which the asphalt is exposed.
