PROCESS FOR RENEWABLE ENERGY FORMATION
A method of generating hydrogen from an offgas includes obtaining the offgas from a renewable diesel unit (RDU). The method further includes inputting the offgas to a steam methane reformer (SMR).
1 . A method of generating hydrogen from an offgas, said method comprising the step of obtaining the offgas from a renewable diesel unit (RDU) and inputting the offgas to a steam methane reformer (SMR), wherein the hydrogen is produced via utilization of the SMR.
2 . The method of claim 1 , wherein the hydrogen is renewable hydrogen.
3 . The method of claim 1 , wherein the hydrogen is produced with lower levels of nitrogen oxide (NOx) emissions.
4 . The method of claim 3 , wherein the lower levels of NOx emissions are less than 0.05 lb/MMBtu.
5 . The method of claim 3 , wherein the lower levels of NOx emissions are provided post-selective catalytic reduction (SCR).
6 . The method of claim 3 , wherein the lower levels of NOx emissions are reduced up to an additional 95%.
7 . The method of claim 1 , wherein the offgas is selected from the group consisting of carbon monoxide, carbon dioxide, methane, ethane, propane, butane, hydrogen, and any combination thereof.
8 . The method of claim 1 , wherein the SMR comprises a pressure swing adsorption (PSA) process.
9 . The method of claim 1 , wherein the offgas is inputted to the SMR via a compressor.
10 . A method of generating hydrogen from an offgas, said method comprising the steps of
obtaining the offgas from a renewable diesel unit (RDU),
inputting the offgas to a pre-reformer reactor to produce methane, and
inputting the methane to a steam methane reformer (SMR), wherein the hydrogen is produced from the methane.
11 . The method of claim 10 , wherein the hydrogen is subsequently inputted to the RDU.
12 . The method of claim 10 , wherein the hydrogen is subsequently inputted to a second RDU.
13 . The method of claim 10 , wherein the hydrogen is renewable hydrogen.
14 . The method of claim 10 , wherein the hydrogen is produced with lower levels of nitrogen oxide (NOx) emissions.
15 . The method of claim 10 , wherein the offgas is selected from the group consisting of carbon monoxide, carbon dioxide, methane, ethane, propane, butane, hydrogen, and any combination thereof.
16 . The method of claim 10 , wherein the method is performed to be substantially free of using methane from natural gas.
17 . The method of claim 1 , wherein the CO 2 produced in the SMR and the water gas shift reactor(s) is captured from the syngas.
18 . The method of claim 1 , wherein CO 2 is captured from the SMR flue gas.
19 . The method of claim 1 , wherein CO 2 is captured from the PSA purge gas.
20 . The method of claim 1 , wherein the SMR is provided fuel by renewable hydrogen.
