Liquid cryogen from a tank having a head space pressure P1 is vaporized with a pressure building vaporizer to gaseous cryogen and the pressure of the gaseous cryogen is built to a pressure P2. The pressurized gaseous cryogen at pressure P2 is expanded across an expander to decrease its pressure and fed to a point of use at an installation including the vaporizer at a pressure P3. P22P3. Energy from the expanded gas may be recovered in the form of mechanical energy, electrical energy.

The present invention relates to a fuel oil theft prevention tool configured to prevent theft or siphoning of fuel oil from a fuel tank. The tool is compact and lightweight and includes a metal femalefemale reduced coupling, a heavy-duty metal screen having a plurality of holes disposed therein, the screen is positioned inside the reduced coupling and is secured/biased and held tight by a torsional spring, a malefemale hex bushing having a hexagonal head is positioned inside the reduced coupling over the screen for further securing of the screen. The tool is positioned between the fuel delivery pipe and the supply pipe and is configured to allow flow of fuel oil in only one direction.

The present description relates to an adsorbent monolith, method to make the adsorbent monolith, and a gaseous storage system that includes an adsorbent monolith according to the present disclosure. In particular, the adsorbent monolith includes adsorbent, a binder, and a scaffold material.

A method of storing ethane includes storing ethane in a number of storage pipes as a liquid at ambient temperature conditions. The storage pipes may be provided on a tanker.

A pressurized cylinder stand includes a base, a plurality of vertical supports coupled to the base, a safety plate that includes bores configured to fit over the respective plurality of vertical supports, and a plurality of nuts. The base includes a safety cap that includes a seat configured to support a pressurized cylinder that encloses a pressurized hydrocarbon fluid. Each of the plurality of vertical supports includes a threaded portion and an unthreaded portion. The safety plate includes a slot sized to receive a base of the pressurized cylinder. At least two lower nuts are configured to engage the threaded portions of respective vertical supports in contact with a bottom surface of the safety plate. At least two upper nuts are configured to engage the threaded portions of respective vertical supports in contact with a top surface of the safety plate, such that the base of the pressurized cylinder is secured within the slot of the safety plate.

The invention relates to a calculation method (400) for calculating dimensions of spacer elements (40) intended for the construction of a liquid-product storage facility (1), the storage facility comprising a load-bearing structure (10) having an internal space (11) delimited by a load-bearing wall (12) and a sealed tank (20) installed in the internal space (11) of the load-bearing wall (12).

The calculation method (400) is based on an iterative decrease in the dimensions of the spacer elements (40) under the constraint of acceptability criteria, the acceptability criteria comprising planarity criteria limiting deformations of planar facets (224) of the tank (20).

Embodiments of systems, methods, and canisters to filter flammable vapor and release filtered vapor during an overpressure event are disclosed. An embodiment of a method may include flowing a fluid from a sample vessel to a pressure relief device. The fluid may include one or more liquids and one or more flammable gases. The method may include flowing the fluid from the pressure relief device to a pressure flow reducer cylinder when the overpressure event occurs, reducing the pressure flow of the fluid in the pressure flow reducer cylinder, and flowing the reduced pressure flow fluid from the pressure flow reducer cylinder to a canister. The method also may include adsorbing vapors of the one or more flammable gases of the fluid when present in the reduced pressure flow fluid in the canister, thereby to obtain filtered vapor, and releasing the filtered vapor from the canister.
