A solvent storage and depressurization system is described. The system allows a volume of solvent to be stored and used at low pressure, thereby providing safety benefits and regulatory simplicity. The system includes an external expansion tank that is located outside of an extraction facility and that contains a solvent. The system also includes an internal storage tank that is located inside of the extraction facility and that provides a solvent supply to a solvent user, such as a phytochemical extraction system. The external and internal tanks are separated and connected via a duplex manifold. The manifold allows gas below a first pressure level to pass from the external expansion tank to the internal storage tank, and allows gas above a second pressure level to pass from the internal storage tank back to the external expansion tank, wherein the second pressure level is greater than the first pressure level.

Composite tank apparatus and methods of making and using same. An array of flat-sided co-dependent cells with relatively thin skins made of metallic or non-metallic materials. Each cell has at least two flat wall panel portions connected by radiused sections arranged such that all of the flat wall panel portions are either in flush contact with each other or in flush contact with flat supporting panels of an enclosing structure or thermal insulating material lining an interior thereof. The cells are sealed with each other around a perimeter of at least one pair of matching lightening through-wall holes provided in adjacent pairs of the wall panel portions of the cells to resist relative movement and prevent leakage of fluid therefrom. The composite tank apparatus may include an enclosing structure, and optionally, one or more layers of thermally insulating material lining the interior surface or the exterior surface of the enclosing structure.

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.

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of sealing, reinforcement, sensing, protection, and interspatial injected materials.

A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.

A cryogenic full containment storage tank for realizing a low-liquid-level material extraction function by using a pump column, comprising an inner tank, an outer tank, a pump column, a submersible pump and a material pre-extraction device; wherein the material pre-extraction device comprises a cofferdam, a Venturi mixer, a backflow pipe, a return control valve, a lead-out pipeline and a liquid level detection system. The cryogenic full containment storage tank can make use of a low-temperature medium flowing back from the pump column to extract the low liquid level material outside the cofferdam into the cofferdam to form a local high liquid level and maintain the normal operation of the submersible pump.

Implementations of the present disclosure generally relate to an apparatus for large-scale external pressure storage, and more particularly for large-scale storage of liquid hydrogen and other products that require evacuated insulation. In some examples, a plate for a storage apparatus is provided. The plate a body that includes a beveled joint with the body having a nominal thickness at the beveled joint. The beveled joint is configured to be welded to a corresponding beveled joint of an adjacent plate.

A storage tank includes an upper tank having a cylindrical shape and a lower circumferential edge having a contoured shape. A top surface of a tank floor body is in sealing contact with the lower circumferential edge and conforms to the contoured shape. The tank floor body has a saddle shape. An upper cap is joined to an upper circumferential edge of the upper tank. The upper cylindrical tank shell, the tank floor body, and the upper cap form an inner storage volume. The storage tank may also include a lower skirt having a cylindrical shape and an upper circumferential edge having the contoured shape. A bottom surface of the tank body floor is joined to the upper circumferential edge and the lower tank skirt, and the upper tank share a common central axis.

The present invention relates to a remote propane-monitoring device primarily comprised of a body with a front surface further comprised of a display and at least one button, a retaining clip and a mobile application. In the preferred embodiment, the body is generally rectangular and is made from a rigid, water-resistant/water-proof, weather-resistant plastic. The body further has a clip assembly that allows the device to attach to a propane gauge of a propane tank and a piping/tubing that attaches to the tank. The device is further comprised of an internal pressure gauge that reads the pressure of the propane gas being pushed out from the tank to determine the level of propane gas left in the tank and relay said information to the mobile application.
