Abstract:
A system for loading and storing CNG onboard of a barge and for unloading it therefrom comprises CNG loading facilities for loading CNG on board of the barge, CNG storage facilities for storing the loaded CNG on board of the barge at nominal storage pressure and temperature, and CNG unloading facilities for unloading CNG to a delivery point. The delivery point requires the unloaded CNG to be at delivery pressure and temperature generally different from the storage pressure and temperature. Thus, the CNG unloading facilities comprise a CNG heater for heating the to-be-unloaded CNG prior to unloading, and a lamination valve for allowing the to- be-unloaded CNG to expand from its storage pressure to the delivery pressure. A compressor may also be provided to compress CNG that would not otherwise be spontaneously delivered.

Abstract:
A liquefied gas tank includes an inner tank (2) that stores liquefied gas and is disposed so as to be capable of self-standing on a floor surface (F), and an outer tank (3) that is covered over the inner tank (2) and is supported by an upper face portion (2a) of the inner tank (2). The outer tank (3) is configured to be capable of sliding on the upper face portion (2a) of the inner tank (2) in response to expansion and contraction in the horizontal direction of the inner tank (2), and to be capable of moving in response to expansion and contraction in the vertical direction of the inner tank (2). A ceiling portion (3a) of the outer tank (3) that is placed on the upper face portion (2a) of the inner tank (2) is not fixed to the upper face portion (2a) of the inner tank (2), and the inner tank (2) and the outer tank (3) are configured to be capable of sliding in the horizontal direction relative to each other. The outer tank (3) includes an expansion and contraction mechanism portion (33) that is disposed along the lower outer circumference thereof.
Abstract:
The invention relates to a protective cap for a pressurised fluid cylinder valve, comprising a body having one end intended to be mounted on a cylinder and another end including a manual gripping member (1) mounted such that it can rotate in relation to the rest of the body of the cap (5), in order to allow the rolling of a cylinder provided with such a cap while the cylinder is being maintained vertical manually using the gripping member (1). The gripping member (1) rotates together with a rotary shaft (2) rotatably mounted in a stationary bearing (3) solidly connected to the body of the cap (5). The cap is characterised in that the gripping member (1) is over-moulded onto the rotary shaft (2).

Abstract:
Customers with an increased demand for technical gases are normally supplied with gas bottle packs. These are gas supply systems in which a plurality of commercially available pressurized gas bottles are connected to one another via a pipeline system which is simultaneously equipped with a connection for extracting gas and for filling the pack. Here, the fill pressure of the pack must correspond to the extraction pressure demanded by the customer. According to the invention, the pipeline system comprises at least two outlets which are designed in each case for different pressures, for example for 300 bar and for 200 bar. For this purpose, at least one of the outlets is equipped with a valve for pressure reduction. In this way, the extraction of gas at different extraction pressures is possible with one arrangement.

Abstract:
A security device for gas cylinders or crates of gas cylinders, comprises a carrier adapted to be fixed to the gas cylinder or crate; a REID-tag provided on said carrier having a storage for storing an expiry date or any other data regarding the durability of the gas contained in said gas cylinder; a processor for checking the durability; and a display indicating the durability and/or passing of the expiry date. The security device may have a closed electric circuit with a current- or voltage supply adapted to be switched off; and means for generating an optic-, acoustic- and/or wireless transmittable alarm signal upon disruption of the electric circuit.
