Abstract: A fluid distribution device is presented for the collection and distribution of fluid between reactor beds. According to various aspects, the device includes a collection tray, a mixing chamber in fluid communication with the collection tray, a rough distribution tray in fluid communication with the mixing chamber, and a fine distribution tray in fluid communication with the rough distribution tray. The rough distribution tray includes an overflow weir with an upper liquid retention baffle.

Abstract: A vessel tray clamp is provided. The vessel tray clamp includes a distal end lying in a first plane and having a first width. The vessel tray clamp also includes a proximate end lying in a second plane that is not the first plane. The proximate end has a second width greater than the first width and has an elongated opening therethrough. An arcuate intermediate portion interconnects the distal end and proximate end. The arcuate intermediate portion has the first width adjacent the distal end and the second width adjacent the proximate end to form a shoulder therebetween.
