Abstract
Official abstract text for this publication.
In a heat integrated distillation column (HIDiC), the product purity can be stably maintained against various disturbances. Provided is a method for controlling a distillation apparatus, which includes a high-pressure part including the whole or a part of a rectifying section and performing gas-liquid contact at a relatively high pressure; a low-pressure part including the whole or a part of a stripping section and performing gas-liquid contact at a relatively low pressure; a line for directing overhead vapor of the low-pressure part to a column bottom of the high-pressure part; a line for directing a column bottom liquid of the high-pressure part to a column top of the low-pressure part; and a heat exchange structure for transferring heat from the rectifying section to the stripping section, wherein the method includes controlling a flow rate of the column bottom liquid to be directed from the high-pressure part to the low-pressure part. Also provided is the distillation apparatus including a flow rate control means in the line for directing the bottom liquid of the high-pressure part to the low-pressure part.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for controlling a distillation apparatus which comprises a high-pressure part comprising the whole or a part of a rectifying section and configured to perform gas-liquid contact at a relatively high pressure; a low-pressure part comprising the whole or a part of a stripping section and configured to perform gas-liquid contact at a relatively low pressure; a line for directing an overhead vapor of the low-pressure part to a column bottom of the h…
