Abstract
There are provided CCUS systems and methods having gas-to-liquid systems and processes, e.g., for processing flare gas to methanol. In these systems an air-breathing engine reformer produces a syngas intermediate that is further converted to methanol in a downstream synthesis step. The CCUS system has a CO2 separator that receives a gas-phase stream and separates this stream into two streams, a CO2-rich stream and a CO2-depleted stream. The CCUS systems may further have a hydrogen separator that receive a gas-phase stream and separates that stream into a hydrogen-rich stream and a hydrogen-depleted stream. The CO2-rich stream can be used for use in EOR, storage or both.
Claims27
A gas-to-liquid system comprising a primary synthesis loop configured for operation at a pressure above about 30 bar, the system further comprising:
- a. a means for providing a high-pressure process stream containing CO2, after (i) condensation and collection of a liquid product, (ii) collection of an easily condensable product or (iii) both products;
- wherein the products comprise one or more of as methanol, ethanol, mixed alcohols, ammonia, dimethyl-ether F-T liquids;
- b. a CO2 separator, wherein the CO2 separator is configured to operate based on mechanical separation of a condensed-phase, a solid, a liquid, or a solid and liquid, CO2;
- and,
- c. a means for capturing a CO2-rich stream for use, sequestration or both.
A gas-to-liquid system comprising a primary synthesis loop configured for operation at an operation pressure, the system further comprising:
- a. an infeed line in fluid communication with a source of a high-pressure stream comprising CO2;
- b. a first recuperator in fluid commination with the infeed line;
- c. a turbo expander in fluid communication with the first recuperator;
- d. a CO2 separator in fluid communication with the turbo expander;
- the CO2 separator comprising a first outlet and configured to provide a CO2-depleted stream of gas from the first outlet;
- e. a line placing the first outlet of the CO2 separator in fluid communication with the first recuperator, whereby a CO2-depleted stream of gas is used to cool the high-pressure stream comprising CO2.
A gas-to-liquid system comprising a primary synthesis loop configured for operation at an operation pressure, the system further comprising:
- a. an infeed line in fluid communication with a source of a high-pressure stream comprising CO2;
- b. a first recuperator in fluid commination with the infeed line;
- c. a second recuperator in fluid communication with the first recuperator;
- d. a turbo expander in fluid communication with the second recuperator;
- e. a CO2 separator in fluid communication with the turbo expander;
- the CO2 separator comprising a first outlet and configured to provide a CO2-depleted stream of gas from the first outlet;
- the CO2 separator comprising a second outlet and configured to provide a CO2-rich stream of material from the second outlet;
- f. a line placing the first outlet of the CO2 separator in fluid communication with the first recuperator, whereby a CO2-depleted stream of gas is used to initially cool the high-pressure stream comprising CO2;
- g. a line placing the second outlet of the CO2 separator in fluid communication with the second recuperator, whereby the CO2-rich stream of material is used to further cool the high-pressure stream comprising CO2;
- and,
- h. a line placing the second recuperator in fluid with a CO2 storage, transfer or both device, whereby the CO2-rich stream of material is stored, transferred or both.
