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.

Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

Cryogenic fluid storage tank comprising a pipe for drawing off vaporized gas, which pipe is connected to a first casing and comprises a vaporizer and at least one control valve, a first filling pipe connected to the lower portion of the first casing, a second pipe for filling a downstream end connected to the upper portion of the first casing, a distribution valve assembly configured to enable distribution of the fluid from the fluid source in the filling pipes, a pressurization pipe connected to the lower end of the first casing and a second end connected to the upper portion of the first casing and at least one control valve and a heater, the tank further comprising an air vent regulator, the valve assembly for distribution in the filling circuit, the valve for controlling the pressurization pipe, the valve for controlling the drawing-off circuit and the air vent regulator being integrated into the same valve module, which shares at least one valve element.

A valve for pressurized fluid including a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit including a collection of valve shutter(s) including at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve including a member for manually controlling the collection of valve shutter(s).

The invention relates to a tank for storing a two-phase cryogenic mixture of liquid and gas, comprising a first casing, at least one drawing pipe, a tank filling circuit, the tank comprising a sensor assembly measuring the pressure in the first casing, the tank comprising a pipe for pressurizing the internal casing, comprising an upstream end connected to the lower end of the first casing and a downstream end connected to the upper part of the first casing, the pressurization line comprising at least one regulating valve and a heater, in particular a vaporization heat exchanger. The invention is characterized in that the regulating valve is configured to automatically maintain the pressure in the first casing at a minimum value by ensuring, when the pressure in the first casing is lower than said first value, a circulation of liquid taken from the first casing in the heater and a re-injection of said heated fluid into the first casing.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with a multi-function nozzle assembly including an exhaust nozzle corresponding to a vehicle exhaust port and a fuel nozzle for supplying fuel to a vehicle fuel tank. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. An exhaust conduit may be configured to transport captured exhaust therethrough from the exhaust nozzle to an exhaust holding tank connected to and in fluid communication with the exhaust conduit.
