Abstract
Processes and apparatuses for operating a centrifugal gas compressor. A storage tank containing a liquid buffer material is provided and used to offset density fluctuations in the gas stream passed to the compressor. The storage tank may contain a component of the high-pressure gas stream provided by the compressor, such as carbon dioxide.
Claims20
A process for compressing a gas stream, the process comprising:
- passing a feed stream to a centrifugal compressor, the feed stream comprising a gas stream;
- mixing, upstream up of the compressor, a buffer stream, from a storage vessel, with the feed stream, wherein the storage vessel comprises a liquid buffer material, and the buffer stream comprises a gaseous phase of the liquid buffer material;
- and,
- increasing a pressure of the feed stream and the buffer stream in the compressor to provide a high-pressure gas stream having pressure greater than a pressure of the feed stream.

A process for compressing a gas stream, the process comprising:
- passing a feed stream to a centrifugal compressor, the feed stream comprising a gas stream;
- obtaining data on one or more conditions of the feed stream;
- comparing the obtained data against one or more threshold values and when the obtained data is outside of the one or more threshold values, mixing, upstream up of the compressor, a buffer stream, from a storage vessel, with the feed stream, wherein the storage vessel comprises a liquid buffer material, and the buffer stream comprises a gaseous phase of the liquid buffer material;
- and,
- increasing a pressure of the feed stream and the buffer stream in the compressor to provide a high-pressure gas stream having pressure greater than a pressure of the feed stream.
2 more elements
An apparatus for producing a high-pressure gas stream, the apparatus comprising:
- a centrifugal compressor configured to receive a gas stream and provide the high-pressure gas stream having a pressure higher than a pressure of the gas stream;
- a storage tank comprising a liquid buffer material;
- a line configured to provide a stream from the storage tank to the compressor;
- and,
- a valve in the line configured to control a flow rate of the stream provided to the compressor.
