A method of generating a pressurized, sub-cooled mixed-phase cryogen is disclosed, including providing a cryogenic system including a reservoir containing a liquid cryogen; and a heat exchange coil immersed in the liquid cryogen, the heat exchange coil having an input end and an output end not immersed in the liquid cryogen; introducing a pressurized gas cryogen to the input end of the heat exchange coil; cooling the pressurized gas cryogen within the heat exchange coil; and collecting the pressurized gas cryogen at an output end of the heat exchange coil.

A mobile storage apparatus for containers is provided. The apparatus provides a unique support assembly for holding a container. The assembly includes a latch mechanism that allows a clamp of cylinder to be moved from a closed position to an open position which creates clearance around a neck of cylinder to allow it to rotate without falling out of clamp. The other end of apparatus is structurally configured with a release plunger that can be retracted to allow rotation of cylinder along said other end. Rotatable wheels on a user side with a braking mechanism along a handle and a foot ledge allow improved maneuverability and stability.

Disclosed is a tank foot ring comprising: a body for supporting a pressurized tank made of polymeric material; and the body having an open end enclosing a hollow space or spaces on which a bottom portion of the pressurized tank rests and wherein the open end is in air flow communication with such hollow space or spaces, and an opposing surface for contacting a ground surface on which the foot ring rests. The opposing surface has a series of openings for drainage of water from the hollow space or spaces. Further provided is a collar for mounting on a top portion of a pressurized tank. The collar comprises: a body, a fastening system and a rotatable lid disposed on the collar. Further provided is a collar with a window cut-out for viewing tank data and a regulator mounting clip for securing a regulator of the tank in place during use.

A system and a method for processing and storing hydrocarbon gas. A gas conditioning and compression transport comprises a gas conditioning system for processing hydrocarbon gas received from the hydrocarbon fuel source and a compression system. The compression system comprises a dual shaft electric motor capable of driving a first compressor and a second compressor to compress the hydrocarbon gas. A gas compression and storage transport receives the processed hydrocarbon gas from the gas conditioning and compression transport. The gas compression and storage transport is capable of directing a first portion of the processed hydrocarbon gas to bypass processing at the gas compression and storage transport and diverting a second portion of the processed hydrocarbon gas for storage. A storage compressor compresses the second portion of the hydrocarbon gas for storage in one or more gas storage tanks.

A nasal prong or nasal mask cannula system which has at least one of the following features: to enhance the cannula tubing at the port base of the oxygen source to minimize “crimping” and diminished oxygen delivery; to design a cannula that will expand in length as needed and shorten as needed without loss of pressure (PSI) of oxygen from start point of oxygen source to patient; to provide a device such as a clasp or clip attached to the cannula which clasp or clip may be attached to the patient's clothing to relieve pressure or weight exerted by the cannula tubing on the patient's ears and keep the cannula close to the patient's body; to provide storage means for storing extra length of tubing; to provide a warning device to alert the patient when oxygen levels or oxygen flow rate are low or that the battery energizing the warning device is low; to provide a timing device to alert the patient to change the cannula after a prescribed period of time; to provide means for stylizing or personalizing the cannula system; to provide an oxygen supply system with a regulator which includes an external outlet or port that includes a pivot of at least 180° and optimally 360°.

An oxyacetylene type work apparatus including a first container containing acetylene; a first pressure gauge configured to measure the pressure in the first container, a first two-dimensional marking disposed on the first dial, a second container containing oxygen; a second pressure gauge configured to measure the pressure in the second container, a second two-dimensional marking disposed on the second dial, an image capturing device configured to produce images of the first pressure gauge and of the second pressure gauge; an electronic logic circuit configured to process said images of the first and second pressure gauges thereby determining the respective angular positions, and a sensor configured to measure the temperature of the first acetylene container.

An enhanced operating method and an integrated tube-trailers and stationary ground storage system are provided for implementing enhanced pressure consolidation operations for refueling gaseous fuels. The integrated tube-trailers and stationary ground storage system includes gaseous fuel supply tube-trailers and stationary ground storage including at least one or more stationary pressure vessels. A compressor can be supplied by both the stationary ground storage and the tube-trailers. The stationary ground storage can provide higher pressure to the compressor than the tube-trailers, enabling enhanced compressor throughput during refueling operation, and enhanced utilization of tube-trailers payload.

Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a polygonal sidewall extending from the first end to the second end. The vessel further having a top, a bottom, at least one side, and an internal surface, and an outlet fluidly coupled with the bottom; and a chemical-resistant lining associated with the internal surface of the sidewall and being substantially flexible. A scrubber tank is supported by the frame and fluidly connected to the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.
