Abstract
A method for producing a fuel includes transporting one or more pressure vessels containing pressurized biogas from a first location to a second location, and removing biogas from the one or more pressure vessels at the second location. The fuel production process is improved by controlling the decanting flow rate to provide a total decant time greater than 30-40 minutes, by actively heating biogas contained within the one or more pressure vessels, or some combination thereof.
Claims20
A method of producing renewable fuel comprising:
- a) receiving a plurality of pressure vessel systems, said plurality of pressure vessel systems comprising a first pressure vessel system containing a first biogas having a first density and a second pressure vessel system containing a second biogas having a second density;
- b) providing fluid communication between the first pressure vessel system and a first valve and between the second pressure vessel system and a second other valve, each of said first and second valves in fluid communication with a same pressure let down system;
- c) unloading the first and second biogases from the first and second pressure vessel systems, respectively, wherein said unloading comprises actuating the first and second valves such that the pressure let down system receives biogas from the first and second pressure vessel systems in succession before the first biogas is fully unloaded from the first pressure vessel system;
- and
- d) feeding at least a portion of first and second biogases unloaded in step (c) into a biogas upgrading system, a fuel production process, or a combination thereof.

- c) unloading the first and second biogases from the first and second pressure vessel systems, respectively, wherein said unloading comprises actuating the first and second valves such that while unloading each of the first and second pressure vessel systems a first portion of the respective biogas is provided from a first pressure let down system at a pressure above 3.4 MPa, and a second portion is provided from a second other pressure let down system at a pressure below 3.4 MPa;
- and
- and
- d) feeding the first and second biogases unloaded in step (c) into a biogas upgrading system, a fuel production process, or a combination thereof.
