摘要:
A system that can offload compressed gas from a storage tank to a customer site. The system can have a fluid circuit that is configured to fit within a container structure, like a trailer, for mobility to remote locations. This fluid circuit can include a transfer unit to automatically switch between tanks. The transfer unit can couple with a heat exchanger. Downstream of the heat exchanger, the fluid circuit can reduce pressure of fluid from the tanks through multiple pressure reduction stages. Each of the pressure reduction stages can include a throttling device, for example, a pilot-type fluid regulator and a control valve assembly. The throttling device may be selected to maintain flow of fluid at least at, e.g., 35,000 scfh, in accordance with pressure drops in the incoming fluid from the tanks.

L'invention porte sur un robinet (1) de distribution de gaz comprenant une embase (2) et un système de détente de gaz interne (20, 21, 22). Une coiffe (12) surmonte l'embase (2), ladite coiffe (12) étant mobile par rapport à l'embase (2) entre au moins une position de fermeture dans laquelle la coiffe (12) vient repousser le clapet de détente (20) du système de détente de gaz interne (20, 21, 22) contre le siège de clapet (21) de manière à obturer totalement l'orifice de détente (22) et empêcher toute détente de gaz, et une position de détente dans laquelle la coiffe (12) permet au clapet de détente (20) de s'éloigner d'une distance donnée du siège de clapet (21) de manière à libérer l'orifice de détente (22) et à permettre une réduction de pression du gaz entre le clapet (20) et le siège de clapet (21). Un élément élastique (13) vient repousser élastiquement la coiffe (12) dans un sens tendant à l'éloigner de l'embase (2) pour la faire passer de la position de fermeture à la position de détente. Récipient de gaz (30) équipé d'un tel robinet (1) et son utilisation pour distribuer du gaz, notamment de l'oxygène.
摘要:
In order to overcome the problems that liquefied natural gas (LNG) handling at earlier LNG transfer terminals, in particular at earlier LNG import/export terminals, has experienced, the present invention proposes to reduce the temperature of LNG transferred from at least one LNG supply source (10) to at least one land tank (20).
摘要:
This method for replenishing the supply of cryogenic liquid from a storage tank (2) involves the following steps: - pressurizing a container (14) with cryogenic gas at a first pressure, said container having passing through it a first cryogenic fluid flow line referred to as the cold line and a second cryogenic fluid flow line referred to as the hot line, - passing cryogenic liquid at a second pressure through the cold line (12), and - supplying the container (14) with cryogenic gas at least partially from cryogenic liquid pumped from the storage tank (2) and vaporized. The device according to the invention is a device for implementing a method like the method described hereinabove.

The invention provides a mobile and/or transportable system for natural gas supply to end consumer and a method for emergency supply of natural gas to an end consumer. Occurrences of temporary or long term shut down of a power plant, an industrial plant or a distribution area is a very expensive and uncomfortable mishap. Such shut downs are either unexpected (due to accidental breakdowns etc.) or scheduled maintenance shut downs and have severe impact on the profitability of the gas receiving stations and their customer reliability.
摘要:
