To provide a method for stably storing tetrafluoropropene filled in a container for e.g. storage or transportation, without occurrence of reaction such as polymerization.

A method for storing tetrafluoropropene in a gaseous-liquid state composed of a gas phase and a liquid phase in a closed container, wherein the oxygen concentration (content) in the above gas phase is adjusted to at least 3 vol ppm and less than 3,000 vol ppm at a temperature of 25 C.

A pressure tank includes a metallic vessel, a plastic liner received in the metallic vessel, a flexible diaphragm, two connectors and a nozzle coupled to the nipples respectively. The metallic vessel includes upper and lower shells. The upper shell defines a first planar area on a side thereof and a second planar area on a top thereof. The lower shell defines a third planar area thereunder. The flexible diaphragm divides the metallic vessel into a storage space and a pneumatic room. Each of the connectors includes a nipple and an anti-leak assembly. The nipples of the connectors are mounted on the side and top of the upper shell respectively and are in communication with the storage space. The two anti-leak assemblies provide leakproof connection between the nipples and the plastic liner. Additionally, the nozzle is mounted on the third planar area to be in communication with the pneumatic room.

The invention relates methods of reducing the risk or preventing the occurrence of an adverse event (AE) or a serious adverse event (SAE) associated with a medical treatment comprising inhalation of nitric oxide.

An embodiment of a single use nitrous oxide solution delivery system can be used in a prehospital setting such as in ambulances. A container can be filled with a predetermined relative concentration of nitrous oxide and oxygen gases. The container is sized to be stored in a repository within an automated dispensing cabinet (ADC) for medications. The container is connected to a regulator which includes a main control dial configured to allow a health care provider to adjust the volumetric flow rate of the nitrous oxide and oxygen gas mixture used by a patient. A scavenger can be optionally connected to a patient's mask and configured to remove exhaled gas. Another embodiment of a single use nitrous oxide solution delivery system can be used within hospitals and other medical buildings.

A system that can eliminate engine combustion emissions in addition to raw and fugitive methane emissions associated with a gas compressor package. The system may comprise an air system for starting and instrumentation air supply; electrically operated engine pre/post-lube pump, compressor pre-lube pump, and cooler louver actuators; compressor distance piece and pressure packing recovery system; blow-down recovery system; engine crankcase vent recovery system; a methane leak detection system; and an overall remote monitoring system.

The present disclosure provides a method for stably supplying a highly pure n-butylamine gas having a constant composition. The present disclosure is a composition supply method including: a filling step of filling a container with a composition containing n-butylamine in an amount of 99.5% by volume or more and isobutylamine in an amount of 0.001% by volume or more and 0.5% by volume or less; a warming step of warming the container filled with the composition to 50 C. or higher; and a gas supply step of supplying a gas containing n-butylamine and isobutylamine from the warmed container to a predetermined device.

A gas regulator is described. The gas regulator includes a gas inlet having an attachment mechanism for attaching to a gas container, a gas outlet in fluid communication with the gas inlet and further in fluid communication with a gas delivery system, a pressure regulator, a pressure sensor and a NFC sensor. A method of entering at least one information item relating to a gas source to a gas delivery system control unit. The method includes the steps of providing a gas source having a NFC tag that includes at least one information item stored in a memory of the NFC tag, attaching a regulator that includes a NFC sensor, wherein the NFC sensor is positioned to read the NFC tag when attached to the gas source, reading the at least one information item via the NFC sensor, and transmitting the at least one information item read by the NFC sensor to a gas delivery system control unit.

The invention relates to an apparatus for transferring flammable, hazardous and/or cryogenic fluids, comprising a first coupling part and a second coupling part having a connecting and locking mechanism in order to establish a connection to the first coupling part by connecting contact surfaces comprising sealing devices, so that charge equalization can be established. Furthermore, the invention relates to a method of operating an apparatus for transferring flammable, hazardous and/or cryogenic fluids into or out of a mobile, transportable or stationary storage device such that at first charge equalization is established before the transfer process begins.

A gas supply system includes a first tank, a first path into which a first gas generated by vaporization of a first low-temperature liquefied gas flows, a gas boosting mechanism being disposed in the first path, a second path that is a path configured to extract the first low-temperature liquefied gas from the first tank, a pump and a vaporization mechanism being disposed in the second path and a reliquefaction path that is a path configured to liquefy at least part of the first gas extracted from an upstream side of the gas boosting mechanism in the first path and to cause the liquefied first gas to flow into an upstream side of the pump in the second path, a cooling heat exchanger configured to cool the first gas by a second low-temperature liquefied gas or a second gas being disposed in the reliquefaction path.

A compressed gas energy storage system may include an accumulator for containing a layer of compressed gas atop a layer of liquid. A gas conduit may have an upper end in communication with a gas compressor/expander subsystem and a lower end in communication with accumulator interior for conveying compressed gas into the compressed gas layer of the accumulator when in use. A shaft may have an interior for containing a quantity of a liquid and may be fluidly connectable to a liquid source/sink via a liquid supply conduit. A partition may cover may separate the accumulator interior from the shaft interior. An internal accumulator force may act on the inner surface of the partition and the liquid within the shaft may exert an external counter force on the outer surface of the partition, whereby a net force acting on the partition is less than the accumulator force.
