Systems and/or methods provided herein relate to cooling of a component within a chamber of a cryostat. A system can comprise a cryostat having a cooling plate disposed within the cryostat, and a cooling feed line extending into the cryostat from external to the cryostat, which cooling feed line is thermally coupled to the cooling plate by a heat exchanger. In one or more embodiments, the system further can comprise a bulk cooling system that employs a liquifiable gas to provide cooling, wherein the bulk cooling system is fluidly coupled to the cooling feed line. In one or more embodiments, the system further can comprise a vacuum pump disposed at the cooling return line and external to the cryostat and physically decoupled from the cryostat by a section of the cooling return line disposed between the cryostat and the vacuum pump.

A system includes a source of pressurized fluid, a primary pressure vessel disposed in fluid communication with the source, and a supplemental pressure vessel disposed in fluid communication with the source and in fluid communication with the primary pressure vessel. The primary pressure vessel has a first life expectancy duration and includes a first structural characteristic. The supplemental pressure vessel has a second life expectancy duration shorter than the first life expectancy duration and includes a second structural characteristic. A method uses a supplemental pressure vessel to predict impending failure of a primary pressure vessel. The method includes connecting a primary pressure vessel to a source of pressurized fluid, fluidly connecting a supplemental pressure vessel with the source and with the primary pressure vessel, and exposing the supplemental pressure vessel to a first fatigue load to cause its failure before failure of the primary pressure vessel occurs.

A vehicle such as a terminal or yard tractor used for freight spotting is provided with one or more individual, portable LPG cylinders of the type used by forklifts facilitating tank swapping on an as-needed basis for reduced downtime. Each auxiliary cylinder is a portable, removable and replaceable cylinder having a fuel capacity less than that of the vehicle's primary tank. A controller interfaced to a sensor and a pump is operative to pump fuel from the auxiliary LPG cylinder and into the fuel line to refill the primary LPG tank when the fuel level of the primary tank falls below a predetermined level. The invention may be factory-installed onto the vehicle, or may be provided as a kit enabling an existing vehicle to be retrofitted with the auxiliary LPG cylinder(s).

A method of distributing liquefied petroleum gas is described. The method comprises receiving payment for a predetermined amount of liquefied petroleum gas, transmitting an instruction to a valve to distribute liquefied petroleum gas monitoring, by a metering device, an amount of liquefied petroleum gas distributed determining, by the metering device, that the amount of distributed liquefied petroleum gas has reached a threshold amount, wherein the threshold amount is based, at least in part, on the predetermined amount, and responsive to determining that the amount of distributed liquefied petroleum gas has reached the threshold amount, transmitting an instruction to the valve to cease distribution of the liquefied petroleum gas.

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.

An LPG reclaim system for withdrawing and reclaiming liquefied petroleum gas (LPG) from an unspent LPG cylinder. The reclaim system has a reclaim station for reclaiming unspent LPG from LPG bottle containers, a compressor for applying a vacuum on the reclaim station and pressurizing LPG vapor from the reclaimed LPG fluid, and a receiving tanlc for receiving a stream of pressurized liquid LPG. The reclaim system has a pair of shell-and-tube heat exchangers include cold-side tubes and a hot side shell. The reclaimed LPG fluid is passed through the cold-side tubes, while the pressurizing LPG vapor is passed through the hot-side shell of the heat exchanger. The heat applied to the cold-side reclaimed LPG fluid promotes evaporation of the LPG fluid to LPG vapor for pressurizing, and the cooling applied to the hot-side pressurized LPG vapor promotes condensation of the LPG vapor to LPG liquid for the refill containers.

A system is provided for loading one or more transport tank. The system comprises one or more load lines for connecting between on-site storage tanks or vessels and the transport tanks; one or more vapour return lines for connecting between the transport tanks and an on-site flare or downstream units; an oxygen deficient medium source; one or more oxygen deficient medium blend supply lines connectable to each of the vapour return lines; a HMI/PLC for automation and control of the operations of the system; and a control panel in communication with the HMI/PLC for starting and stopping operation of the system. Gases displaced from the transport tanks during loading can be sent directly to flare or downstream units. A method is provided for loading a fluid from one or more on-site storage tanks or vessels to one or more transportation tanks in which gases displaced from the transport tank during loading are sent directly to flare or downstream units; and the method is automatically monitored and controlled via an HMI/PLC.

A dual-purpose displacer for adjusting a liquid cryogen level in a cryostat, the dual-purpose displacer includes a displacer wall having an exterior displacer surface and an interior displacer surface. The interior displacer surface defines a displacing chamber configured to contain a first portion of liquid cryogen. The exterior displacer surface is configured to displace a second portion of liquid cryogen contained in a cryogenic chamber of the cryostat. The dual-purpose displacer is disposed within the cryogenic chamber of the cryostat and configured to transfer the first portion of liquid cryogen contained within the displacing chamber to the cryogenic chamber.

A system for maintaining a substantially constant pressure within an ullage space of a cryogenic storage tank is provided. The system includes a compressor configured to receive fuel gas from the cryogenic storage tank, and compress the fuel gas to produce heated fuel gas. The system further includes a heat exchanger in flow communication with the compressor and configured to cool the heated fuel gas to produce cooled fuel gas, and a turbine in flow communication with the heat exchanger and configured to expand the cooled fuel gas to produce a gas and liquid mixture having a predetermined liquid to gas ratio, and discharge the gas and liquid mixture into the cryogenic storage tank.
