Abstract
Processes and apparatuses for heating process fluid in a furnace. Fuel to the furnace is either hydrocarbons or hydrogen. The fuels may be sent to different furnaces or be sent at different times to the same furnace. Furnaces that are configured to receive both types of fuels may have different exhaust paths. An exhaust path for hydrocarbon fuel flue gas includes a carbon capture process zone.
Claims14
An apparatus comprising:
- a first furnace configured to receive a first fuel, the first furnace having a burner configured to inject the first fuel into the first furnace and produce a flame and a flue gas;
- and,
- a second furnace configured to receive a second fuel, the second furnace having a burner configured to inject the second fuel into the second furnace and produce a flame and a flue gas;
- wherein both of the first furnace and the second furnace are configured to receive a fluid to be heated;
- wherein one of the first fuel and the second fuel comprises a hydrogen stream, and
- wherein the other of the first fuel and the second fuel comprises a hydrocarbon stream,
- wherein the first and second fuels are segregated from each other.
4 more elements
A furnace comprising:
- a first inlet configured to receive a first fuel, the first fuel comprising one of a hydrogen fuel and a hydrocarbon fuel;
- a second inlet configured to receive a second fuel, the second fuel comprising the other of the hydrogen fuel and the hydrocarbon fuel;
- a third inlet configured to receive combustion air;
- a burner configured to receive the combustion air, the first fuel, and the second fuel and inject the combustion air, the first fuel, and the second fuel into the furnace and provide a flame and a flue gas;
- a tube configured to contain process fluid to be heated in the furnace;
- a first exhaust path for the flue gas produced by in furnace, wherein the first exhaust path comprises a carbon capture process zone;
- a second exhaust path for the flue gas produced by in furnace;
- and,
- means for controlling a gas flow configured to change orientation so that when the first inlet is opened, only the first exhaust path is opened and when the second inlet is opened, only the second exhaust path is opened.
6 more elements
A process for generating carbon credits, the process comprising:
- passing a first fuel to a first furnace, the first furnace having a burner configured to receive combustion air, inject the first fuel and the combustion air into the first furnace, and produce a flame and flue gas, wherein the first fuel comprises a hydrocarbon stream, wherein at least a portion of the hydrocarbon stream comprises hydrocarbons produced from a biobased feedstock;
- heating a first fluid in the first furnace;
- passing a second fuel to a second furnace, the second furnace having a burner configured to receive combustion air, inject the second fuel and the combustion air into the second furnace, and produce a flame and flue gas, wherein the second fuel comprises a hydrogen stream;
- heating a second fluid in the second furnace;
- recovering carbon compounds from the flue gas from the first furnace;
- and,
- determining an amount of carbon compounds attributable to the hydrocarbons produced from the biobased feedstock so as to generate a carbon credit.
