There are two other distillation columns in this plant.

Most of the steam is used to heat the reboilers in the distillation columns.

This is what happens in a continuous distillation column.

A mixture is heated up, and routed into the distillation column.

The oil refining process starts with a fractional distillation column.

Such a distillation column is typically called a depropanizer.

This process uses a pre-concentration distillation column as first separating step.

The fractional distillation column is set up with the heat source at the bottom on the still pot.

Packing material can be used instead of trays to improve separation in distillation columns.

Very few of the components come out of the fractional distillation column ready for market.

For smaller applications, a series of heat exchangers may be used as an alternative to distillation columns.

"Why else was Trizein rigging up a fractional distillation column?"

Design and operation of a distillation column depends on the feed and desired products.

Additional heat is removed from the distillation column by a pumparound system as shown in the diagram below.

In this continuous process, a distillation column is fed with potassium chloride and sodium.

New feed is always being added to the distillation column and products are always being removed.

Hence, a distillation column needs more plates than the number of theoretical vapor-liquid equilibrium stages.

The availability of powerful computers has also allowed direct computer simulation of distillation columns.

High distillation column pressure initiates action to open a pressure vent valve.

In a typical classical distillation column, all the vapor driving the separation comes from the reboiler.

This plant consists of four distillation columns.

This column is the tallest distillation column in Australia.

These materials were separated in two distillation columns; the depropaniser and the benzene column.

The main parts of the conventional batch distillation columns are the followings:

The resulting steam enters a fractional distillation column.
