Packed distillation columns - Chemical Unit Operations II.

Packed distillation columns Packed columns are used for distillation, gas absorption and liquid-liquid extraction. The gas-liquid contact in a packed column is continuous, not stage-wise, as in a plate column. The liquid flows down in the column over a packing surface and the vapor (or the gas) moves counter-currently, up the column.

Factors Affecting Distillation Column Operation

The performance of a distillation column is determined by many factors, for example: feed conditions . Column Diameter : . Most distillation columns are open to the atmosphere. Although many of the columns are insulated, changing weather conditions can still affect column operation.

Column Design - Dublin Institute of Technology

Column Diameter The vapour flow rate in either section of the column is obtained from the mass balance in kmol/hr. This is converted to m 3/s as follows: m3/s = (kmol/hr x mol wt.)/(density x 3600) From the continuity equation, q = va.

Distillation Column Piping: Absorption Stripping .

2.0 Distillation Column Piping. The distillation is separation of the constituents of a liquid mixture via partial vaporization of the mixture and separate recovery of vapour and residue. Various kinds of devices called plates or trays are used to bring the two phases into intimate contact.

Towers, Columns - Instruct

Distillation — Distillation is a process which separates a mixture of materials into two or more desired parts. The device which performs this operation may be called a distillation tower, distillation column or fractionator. The operation of a distillation column depends on the fact that different materials boil at different temperatures.
