A method of processing biogas that includes obtaining a mobile tank containing biogas at a pressure greater than 1000 psig, connecting the mobile tank to a pressure let down system, and depressurizing the mobile tank to remove biogas therein. The depressurization includes removing gas from the mobile tank using the pressure let down system, and introducing a warming gas into the mobile tank.

A pressure vessel with a flushing lance, a transport container with pressure vessels and methods of filling and producing this pressure vessel are disclosed which comprises an inner vessel, an outer layer applied on the inner vessel, a valve connection piece arranged on one of the terminal caps of the inner vessel and a hollow flushing lance that is open to the outside and is guided through the valve connection piece and held therein in a sealing manner, wherein the flushing lance protrudes into the storage volume and is provided with a perforation along its entire length up to a first end of the flushing lance facing the terminal cap that lies opposite the valve connection piece in the storage volume for a gas exchange with the storage volume, wherein the flushing lance extends to the terminal cap which lies opposite the valve connection piece.

A sterilized-liquefied gas apparatus of the invention includes: a liquefied gas reservoir; a source-gas supplier that supplies a source gas to the liquefied gas reservoir; a cooler that cools down an inside of the liquefied gas reservoir and thereby liquefies the source gas; a supply pipe that connects the source gas supplier and the liquefied gas reservoir; a sterilization filter provided in the supply pipe; a sterilizer that sterilizes, by a sterilizing gas, a sterilization region that is located further downstream than the sterilization filter; and a sterilizing-gas remover that removes the sterilizing gas after sterilization.

A home-based, low-cost, self-contained, fast-fill natural gas refueling station for providing compress natural gas (CNG) fuel for motor vehicles. The station compresses utility supplied natural gas and stores the CNG in a CNG storage facility located inside the station. In preferred embodiments the refueling station is located adjacent to a driveway at a home. The compressor preferably is a multi-stage gas compressor having at least three stages of compression. Applicant estimates that savings based today prices for CNG as compared to gasoline, a typical family with only one car could pay for the station in three years. If the family has several cars the station could pay for itself much earlier.

A control conduit for liquid hydrogen offloading is configured to couple a controller of a liquid hydrogen offload system to a liquid hydrogen tanker. The control conduit includes a control line and a gas detector. The control line is configured to transmit a control signal from the controller to the liquid hydrogen tanker. The gas detector is configured to detect hydrogen gas and provide a gas detector signal to the controller. The gas detector is secured to the control line at a predetermined distance from a tanker connection end of the control line.

A method for supplying helium to at least one end user is disclosed by feeding helium from at least one container of helium to an end user through at least one supply system, wherein a mass flow meter and a pressure transmitter, in electronic communication with a programmable logic controller measures an amount of helium being supplied to the at least one user, provides the amount to the programmable logic controller which provides a signal to the at least one end user of an amount of helium that remains in the at least one container and the temperature therein.

A fluid container (10) for fluid containment. The internal surface of the container body (12) defines a fluid-containment chamber (14), which has at least one fluid inlet and/or outlet port (18). Associated with at least one fluid inlet and/or outlet port (18), there is a fluid-flow control device, having a control body (16) integrally formed with the container body (12) as one piece.

Method for filling a tank with pressurized hydrogen via a filling station comprising at least one buffer container and a fluid circuit connected to said at least one buffer container, the circuit of the filling station comprising a first end connected to at least one source of hydrogen gas, the circuit comprising a second end fitted with a transfer pipe intended to be connected removably to the tank that is to be filled, the method involving a step of cooling the hydrogen supplied to the tank by transferring negative calories between a cold source and the hydrogen, the method being characterized in that it comprises a step of purifying the hydrogen supplied by the source in a purification member before transferring it to the at least one buffer container, and in that it comprises a step of transferring negative calories from said cold source to the hydrogen before and/or during the purification step.

The invention relates to the field of transportation and storage of gas cylinders, and specifically to a container for gas cylinders, in particular, cylinders for pressurized or liquefied gas, a method for arranging gas cylinders in the container, in particular, cylinders for pressurized or liquefied gas, and a container with gas cylinders, in particular, cylinders for pressurized or liquefied gas. The container for gas cylinders comprises a housing and at least one pipeline positioned to be connected with the gas cylinders in the lower part of the framework. The method comprises arranging the gas cylinders in a framework of the container; and connecting at least one pipeline with the gas cylinders in a lower part of the framework. The container with gas cylinders comprises a framework; at least one gas cylinder; and at least one pipeline connected with the at least one gas cylinder in a lower part of the framework. The technical effect involves simplification and expediting of the removal of condensate and impurities from the gas cylinders during handling the container containing the gas cylinders, in particular, the gas cylinders for natural gas. The additional technical effect is the reduction of the amount of condensate and impurities in the gas cylinders, in particular, the gas cylinders for natural gas, during handling the container containing the gas cylinders, in particular, the gas cylinders for natural gas.
