Methods and systems are disclosed to compress raw, liquids-rich natural gas to high pressures while removing heavier hydrocarbons and water through inter-stage gas processing. Some variations provide a method for purifying and compressing natural gas, comprising: conveying a methane-containing input stream to first-compression stages; generating an initial compressed gas stream at a first pressure; conveying the initial compressed gas stream to a low-temperature separation sub-system configured to remove liquid contaminants, thereby generating an intermediate compressed gas stream at a second pressure; conveying the intermediate compressed gas stream to second-compression stages, to generate a compressed gas product stream at a third pressure; recovering purified and compressed natural gas; and feeding the compressed gas product stream into a mobile container. The sub-systems are preferably integrated into a single unit. The invention solves several problems associated with processing and transporting raw natural gas from initial production locations to end markets for final use.

Systems and methods of processing biomass include a conveyor unit associated with an inlet and/or outlet, a microwave generator, a microwave guide connecting the microwave generator to the conveyor unit that includes a microwave opening configured to receive microwave energy via the microwave guide, and a microwave suppression system including a tunnel associated with the material inlet and/or outlet, and including at least one flexible and/or movable microwave reflecting component within the tunnel, the microwave reflecting component configured to be deflected as biomass material passes through the tunnel and then returning to a resting, closed position when the biomass material is no longer passing through the tunnel. The conveyor unit is configured to receive and process the biomass material, including heating the biomass material to at least a first temperature by applying microwave energy to the biomass material.

A method for recovering associated gaseous hydrocarbons from a well for producing liquid hydrocarbons, the method comprising (i) providing gaseous hydrocarbons from a hydrocarbon well; (ii) providing a cryogenic liquid from an air separation unit or an associated nitrogen liquefaction facility within proximity of the hydrocarbon well; (iii) liquefying the gaseous hydrocarbons at a hydrocarbon liquefaction facility within proximity to the hydrocarbon well to thereby produce a liquefied hydrocarbon gas, where heat associated with the gaseous hydrocarbons is transferred to the cryogenic liquid; and (iv) transferring the liquefied hydrocarbon gas to an air separation unit or nitrogen liquefaction facility.

Provided is a device that uses a high-temperature exhaust gas released from an internal combustion engine to produce a fuel. The present invention relates to the fuel production device including the internal combustion engine, an electrolysis device connected to the internal combustion engine, and a hydrogenation reactor connected to the electrolysis device, wherein the electrolysis device is a device for decomposing high-temperature water vapor contained in the exhaust gas from the internal combustion engine into hydrogen and oxygen, and the hydrogenation reactor is a device for converting the hydrogen resulting from the decomposition to the fuel.

Systems and methods for rendering cannabis-related waste materials are provided. The method may include inserting a plurality of cannabis-related waste materials into, for example, a mobile rendering vehicle. The method may further include physically altering the cannabis-related waste materials such that the cannabis-related waste materials are unrecognizable and unusable. The insertion of the cannabis-related waste materials into the mobile rendering vehicle may be recorded and/or the physical alteration (e.g., pulverization) of the cannabis-related waste materials may be recorded via one or more cameras disposed on the mobile rendering vehicle to verify proper insertion and/or alteration of the cannabis-related waste materials.
