The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

Disclosed in the present invention is a system and method for supplying acetylene to an apparatus using acetylene, the system having at least one acetylene storage apparatus and an acetylene content analysis apparatus. The system and method disclosed in the present invention can utilize the capacity of an acetylene cylinder to a higher degree; before the solvent impurity concentration in acetylene gas reaches a level where it is no longer suitable, a more accurate understanding of the usable acetylene amount in the acetylene storage apparatus can be gained through detection, thereby reducing the number of times that the acetylene storage apparatus is refilled and replaced, and lowering the user's total costs.

A gas magazine for a pneumatic weapon simulator. A gas magazine fill station for a pneumatic weapon simulator. A method of filling a gas magazine for a pneumatic weapon simulator. The apparatus for filling and refilling a fluid reservoir of a magazine for a pneumatic firearm simulator from a source of pressurized fluid of the present disclosure includes: a receiver for receiving the magazine; a passage for conveying the pressurized fluid from the source of pressurized fluid to the fluid reservoir of the magazine received in the receiver; and, a vent valve in fluid communication with the passage for venting the pressurized fluid from the passage. The apparatus may further include a vent channel in fluid communication with the vent valve. The apparatus may also include a valve in fluid communication with the passage which is adapted for permitting pressurized fluid to be conveyed through the passage; and alternately, prevent pressurized fluid from being conveyed through the passage.

An underwater compressed air storage device with at least one underwater compressed air tank, positioned on the floor (7) of a body of water and provided with at least one water outlet opening and at least one inlet opening (11, 13) for a mixture of water and air. A tank which has at least one compressed air storage volume provided with two connecting ducts (9, 11) between said volume and a collection chamber (5) for the water and air mixture, a first duct (9) located in the upper part of the volume ensuring the passage of compressed air in the volume and a second duct (11), at an altitude lower than the first duct (9), ensuring the passage of the water and air mixture in the volume, said tank also having at least one opening for discharging the degassed water into the body of water.

Preloading a containment vessel with Low Vapor Pressure (LVP) liquid; partially evacuating the containment vessel to generate a vacuum in a headspace above the LVP liquid; and relieving material from a process vessel into the containment vessel during a process relief event in the process vessel. The containment vessel pressure may be equalized with ambient conditions prior to preloading the LVP liquid. The containment vessel size and quantity of LVP liquid may be determined to absorb the energy and mass of relieving fluids from the maximum anticipated relief scenario, permitting the gases to condense to liquid form to be recovered in liquid state instead of atmospherically venting or combusting the gases. The containment vessel headspace may be partially occupied with High Vapor Pressure (HVP) liquid comprising C5-C10 hydrocarbons configured to flash during the evacuation step to create and occupy a headspace, providing additional head space volume and heat rejection capacity.
