This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a polygonal sidewall extending from the first end to the second end. The vessel further having a top, a bottom, at least one side, and an internal surface, and an outlet fluidly coupled with the bottom; and a chemical-resistant lining associated with the internal surface of the sidewall and being substantially flexible. A scrubber tank is supported by the frame and fluidly connected to the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

A novel and improved inventive valve with a regulating function is provided that is capable of filling to higher fill pressures than previously attainable with conventional C-10 on-off valves. The valve contains a single flow passageway by which gas dispenses and enters the valve. A fill adapter is specially configured to engage the valve to allow filling at the higher pressures along the single flow passageway. The structure of the valve allows greater utilization of cylinder capacity; simplifies filling and dispensing with the single flow passageway; and allows for regulating gas pressure during delivery without increasing the overall size of the cylinder package.

A modified vacuum actuated valve assembly and sealing mechanism is provided for improved sub-atmospheric flow stability characterized by the absence of delivery pressure spikes and flow excursions. The valve assembly includes a non-stationary thermoplastic seat and a stabber. The stabber is characterized by a top portion having a circular periphery designed to mechanically engage and disengage with an inner sealing surface of the thermoplastic seat. The sealing surface is coined to eliminate surface irregularities contained therein, thereby producing a relatively smooth coined mating inner sealing surface for the circular top portion of the stabber. The valve assembly also includes a modified bellows capable of fine tuning the delivery pressure of the valve assembly.

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 safety vacuum supply gas cylinder includes a cylinder body, a pipeline structure, first and second check valves (respectively having first and second check valve opening pressures P.sub.c1, P.sub.c2, wherein P.sub.c1 is greater than an atmospheric pressure P.sub.0). The cylinder body has an opening and an internal space configured to store a gas, wherein the gas forms an internal pressure P.sub.2 smaller than P.sub.0. The pipeline structure, communicated with the opening, has first and second pipelines where the first and second check valves are respectively arranged. An external filling gas enters the cylinder body when a pressure of the external filling gas is greater than P.sub.c1 and P.sub.2. The gas flows out when P.sub.2 is greater than P.sub.c2 and an external environmental pressure.
