Abstract
Example embodiments for a method for compressing gas into a liquified gas using a plurality of pairs of liquid gas displacers in parallel moving a working fluid between each pair of displacers to pressurize the gas, arranging sets of the parallel liquid gas displacers in a series to raise the pressure, directly cooling the gas at each displacer pair, and finally condensing the gas using a coolant, collecting the liquified gas, and pressurizing the liquified gas for use in a pipeline.
Claims20
A method for compressing gas comprising:
- compressing a gas at a first stage compressor to create a first compressed gas;
- cooling the first compressed gas;
- compressing the first compressed gas at a second stage compressor to create a second compressed gas;
- cooling the second compressed gas;
- compressing the second compressed gas at a third stage compressor to create a third compressed gas;
- cooling the third compressed gas;
- compressing the third compressed gas at a fourth stage compressor to create a fourth compressed gas;
- cooling the fourth compressed gas;
- condensing the fourth compressed gas into a liquified gas;
- collecting the liquified gas;
- pressuring the liquified gas;
- delivering the liquified gas into a gas line.

A method for liquifying carbon dioxide comprising:
- Receiving carbon dioxide gas from a source;
- Compressing the carbon dioxide in a plurality of pairs of displacer vessels placed in a parallel configuration to form a stage;
- Cooling the gas using a plurality of discharge coolers, one for each pair of displacer vessels;
