A method of delivering proppant to a well site has the steps of transporting a load of proppant in a vessel to a desired location, moving the load of proppant from the vessel into a container so as to create a proppant-loaded container, unloading the proppant-loaded container into a pneumatic bulk trailer, and transporting the unloaded proppant in the pneumatic bulk trailer to well site. The container is placed onto a bed of a truck and moved in proximity to the vessel. The proppant-loaded container is placed onto a tilting mechanism and then tilted so that the proppant is discharged through a flow gate of a container into a hopper. The proppant in the hopper can then be conveyed to the pneumatic bulk trailer.

A pressure control device is provided for use with a storage container. The pressure control device includes a base defined by a sidewall and a flange extending outwardly from the sidewall, the flange adapted to be connected to a surface of the storage container, the base including a port defined by the sidewall and adapted to be in fluid communication with an interior of the storage container. The pressure control device includes a lid movably coupled to the base to selectively expose the port of the base to an environment surrounding the pressure control device, and a plurality of blind holes formed in a bottom side of the flange of the base. The plurality of blind holes are configured to facilitate connection of the pressure control device to the storage container while preventing leakage from the storage container through the connection, thereby reducing fugitive emissions.

The transport container for concentrated hydrogen peroxide comprises: a cuboid carrier frame; a liquid container provided inside the carrier frame (1) and frictionally connected thereto, said container having an internal volume of between 65 and 500 I and consisting of pure aluminium, chromium-nickel steel, a nickel-based alloy, or a steel coated with a polyolefin or clad on the inner face; a pressure equalisation device and a pressure relief valve, both of which are provided on the upper face of the liquid container; and at least one sealable opening of the liquid container for the charging and/or removal of hydrogen peroxide.

The present disclosure provides for an above-ground mobile storage tank that can be used in a variety of different commercial applications. In one embodiment, the storage tank may comprise a tank shell, wherein the tank shell further comprises at least one floor wall, at least one top wall, and at least four side walls. The side walls may each be affixed to the floor wall and the top wall to from an interior tank space. Each of the wall panels may comprise a copolymer polypropylene material. The storage tank may also comprise a plurality of steel reinforcements, wherein each reinforcement is configured to encapsulate the tank shell. Each reinforcement may be affixed to a trailer, which is configured to transport the tank shell. The storage tank may also comprise a plurality of slip plates located on the trailer to enable the tank shell to float above the trailer.

A bunded tank system suitable for both transport and storage of bulk dangerous industrial liquids is provided. Preferably the tank is containerised to provide efficient use of space and improved logistics for transport and storage. The containerised bunded tank system includes a plurality of bunded sub-tanks arranged in an interlocking manner within an ISO container. In addition the container is fitted with an improved container lock.

A vent system (1) according to the present disclosure is a vent system (1) discharging a gas in an underground space (S1) communicating with a ground space (S2) via a pull-up pipe (22, 23), and includes an inert gas cylinder (12) that is disposed in the ground space (S2) and generates an inert gas, an inert gas supply pipe (13) for supplying the inert gas to the underground space (S1), and a gas concentration measurement sensor (14) that measures a concentration of the gas in the underground space (S1).
