Improved High Performance Trays
From a design and hydraulic standpoint, trays are relatively complex distillation internals. In the ongoing search for higher performance trays, one first must understand the hydraulic and mass transfer aspects of the tray operation such as entrainment, downcomer flooding, and vapor liquid contact. When this is well understood, then various aspects of the deck and/or downcomer designs can more ...
متن کاملNew Highspeed Mass-transfer Trays
The mass-transfer trays HighspeedTray, HighFlexiTray and SieveTray belong to a new generation of mass transfer trays that enable increase the capacity-efficiency profile and the flexibility of tray columns significantly. This increase is achieved by a special vapor and liquid distribution and contact systems installed on these trays and a combination of two different tray designs. These trays c...
متن کاملComparing surgical trays with redundant instruments with trays with reduced instruments: a cost analysis.
BACKGROUND When prearranged standard surgical trays contain instruments that are repeatedly unused, the redundancy can result in unnecessary health care costs. Our objective was to estimate potential savings by performing an economic evaluation comparing the cost of surgical trays with redundant instruments with surgical trays with reduced instruments ("reduced trays"). METHODS We performed a...
متن کاملChoosing Trays and Packings for Distillation
Distillation towers are essential to the chemical process industries (CPI), so it is imperative that they are properly designed and operated. Tower internals are arguably the most important piece of process equipment, since they cannot easily be accessed after startup. If the tower internals malfunction, the distillation tower will follow suit and the entire chemical process will suffer. This a...
متن کاملPneumatic, multiple, simultaneous inoculator for plastic trays.
A device is described which consists of a bonded Plexiglas-silicone rubber plate, perforated to hold capillary pipettes in register with the wells of a plastic tray to be inoculated. Pipette contents are simultaneously discharged by positive air pressure, initiated by closing an exhaust port with the thumb.
