Abstract
There are provided systems and methods for using fuel-rich partial oxidation to produce an end product from waste gases, such as flare gas. In an embodiment, the system and method use air-breathing piston engines and turbine engines for the fuel-rich partial oxidation of the flare gas to form synthesis gas, and reactors to convert the synthesis gas into the end product. In an embodiment the end product is methanol.
Claims36
A carbon-neutral method of converting a flare gas to an end product, the method comprises:
- a. receiving a flow of a flare gas from a source;
- b. compressing the flare gas;
- c. partially oxidizing the flare gas to provide a reprocessed gas;
- wherein the partial oxidation of the flare gas is conducted at a specific entropy of greater than about 7.1 KJ/kg° C., wherein a reference state for the specific entropy is based upon 25° C. and 1 atmosphere;
- and,
- d. converting the reprocessed gas into an end product;
- e. wherein steps a to d produce less than 2.0 kg of CO2 per kg of flare gas received.
A carbon-neutral method of making an end product, the method comprises:
- a. partially oxidizing a flare gas to provide a reprocessed gas;
- wherein the partial oxidation of the flare gas is conducted at a specific entropy of about 7.1 KJ/kg° C. to about 8.6 KJ/kg° C., wherein a reference state for the specific entropy is based upon −273.15° C. and 1 atmosphere;
- b. converting the reprocessed gas into an end product;
- c. wherein steps a) to b) produce less than 2.0 kg of CO2 per kg of flare gas partially oxidized;
- and,
- d. wherein steps a) to b) are net carbon-negative, whereby these steps produce less than about −20 kg CO2e per kg of end product produced.
A carbon-neutral method of making an end product, the method comprises:
- a. partially oxidizing a flare gas to provide a reprocessed gas;
- wherein the partial oxidation of the flare gas is conducted at a specific entropy greater than about 7.5 KJ/kg° C., wherein a reference state for the specific entropy is based upon −273.15° C. and 1 atmosphere;
- b. converting the reprocessed gas into an end product;
- c. wherein steps a) to b) produce less than 2.0 kg of CO2 per kg of flare gas partially oxidized;
- and,
- d. wherein steps a) to b) are net carbon-negative, whereby these steps produce less than about −20 kg CO2e per kg of end product produced.
