The invention relates to a multivalve with a storage bag (30) and to a storage bag (30). The storage bag (30) is configured for temporarily accommodating a liquid gas fuel around a discharge for a liquid gas fuel store (1) formed from a deformable memory material, wherein the storage bag (30) has a temporarily, size-reduced position, an outer diameter of the storage bag (30) then being less than 48 mm, and a second, operative position, the storage bag (30) having a sufficient volume. The invention also relates to a multivalve with a storage bag (30) and to a strorage bag (30) having a bottom (35) with sides (31, 32) rising from the bottom (35), a one-way valve (46, 47) being placed in or close to the bottom (35) and connected to an inlet (40) in the storage bag (30), the one-way valve (46, 47) being welded to he plastic of the storage bag (30).
摘要:
A method for supplying synthesis gas comprising reacting a carbonaceous feed with an oxidant, to generate synthesis gas; forwarding all or part of the generated synthesis gas to an underground storage location, to generate a synthesis gas buffer; and retrieving synthesis gas from the underground storage location and supplying the retrieved synthesis gas to a downstream processing unit, which downstream processing unit is substantially continuously converting synthesis gas. Conveniently the downstream processing unit can comprise a water-gas shift unit and the invention further provides a system for supplying synthesis gas comprising: a gasification unit, for generating synthesis gas from a carbonaceous feed and an oxidant, that is at least directly or indirectly connected to an underground storage location; an underground storage location, for generating a synthesis gas buffer, that is at least connected directly or indirectly to the gasification unit and at least connected directly or indirectly to a water-gas shift unit; and a water-gas shift unit, for generating a shifted synthesis gas, that is at least connected directly or indirectly to the underground storage location.

A new procedure for constructing cryogenic storage tanks involves erecting a freestanding metal liner. The liner is sized and configured to withstand the hydraulic forces the concrete wall of the tank being poured without the need for temporary stiffeners on the inside surface of lower portions of the liner. Lateral tension ties can be connected to anchor ties on an outward surface of the liner and used to tie the liner to outer formwork. These ties may be spaced up to about 2 m apart. Studs can also be provided on the outer surface of the liner, and a cylindrical ring of cryogenic steel can be integrated into the liner.
摘要:
A method for applying to an outside surface of a liquid container an anti-leak, self-healing, layered barrier structure intended to inhibit liquid leakage from that container due to an impacting and piercing projectile. The method includes the steps of (a) spray applying to the mentioned container surface a first barrier layer formed of a high-elastomeric material, (b) thereafter, spray applying to the first barrier layer a second, composite-material barrier layer including a body formed of substantially the same high-elastomeric material used in the first barrier layer, and a distribution in that body of a plurality of liquid-imbiber bead elements designed to react with dimensional swelling and related liquid absorption when contacted by any leakage fluid coming from the mentioned container, and (c) thereafter, spray-applying to the second barrier layer a third barrier layer formed of substantially the same high- elastomeric material used in the mentioned first barrier layer, and in the body of the second, composite barrier layer.
摘要:
This invention is directed to a method for delivering a liquefied compressed gas with a high rate of flow comprising passing a liquefied compressed high-purity semiconductor gas into a storage vessel; positioning a temperature measuring means onto the wall of the compressed gas storage vessel; positioning at least one heating means proximate to the storage vessel; monitoring the resulting temperature with the temperature measuring means; positioning a pressure measuring means at the outlet of the storage vessel and monitoring the vessel pressure; adjusting the heat output of the heating means to heat the liquefied compressed gas in the storage vessel to control the evaporation of the liquefied compressed gas in the storage vessel; and controlling the flow of the gas from the storage vessel.
摘要:
Systems are provided for vehicular, land-based distribution of pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 °C (-190 °F) to about -62 °C (-80 °F) environ. The systems include at least one container that is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 °C (-100 °F).
