摘要:
A system and method of receiving field gas from a compressor station pipeline, and compressing the gas at a remote location with a modular compressor. The compressed gas is collected in a container and transported to a wellsite for use at the wellsite. The gas from the pipeline is directed to the container, and diverted to the modular compressor when pressure in the container approaches pressure in the pipeline. The modular compressor discharge is piped to the container, so that the container is filled with additional gas and at the discharge pressure of the modular compressor.

The present invention relates to a method, as well as a system, for filling a container (100) with an amount of liquid carbon dioxide (CO 2 ) which is partially converted into an amount of solid CO 2 into said container (100), for the purpose of maintaining one or more products, loaded into said container (100), at a defined temperature, below a defined temperature, or within a defined temperature range, which temperature or temperature range is below environmental temperature. The invention further relates to a method and a system for providing identification and traceability data determining the container (100) and its loaded one or more products, and for enabling the identification of said container (100) during transport to a particular destination.

The invention relates to a filling station (1) adapted for filling of a liquid cryogenic refrigerant from a supply tank to a receiver tank, the filling station (1) comprising a flash tank (2) positioned between the supply tank and the receiver tank, this flash tank (2) being adapted to de-pressurize the liquid cryogenic refrigerant that is transferred from the flash tank (2) to the receiver tank, resulting in the formation of a liquid cryogenic refrigerant phase (21) and a vapour cryogenic refrigerant phase (22) within the flash tank (2), and to phase separate the liquid and vapour cryogenic refrigerant phase (21, 22), and a pump (5) positioned between the flash tank (2) and the receiver tank, the pump (5) being adapted for pumping the liquid cryogenic refrigerant out of the flash tank (2) to the receiver tank, wherein the flash tank (2) has a size and the pump (5) has an outflow of liquid cryogenic refrigerant being such that the ratio between the size of the flash tank (2) and the outflow of liquid cryogenic refrigerant out of the pump (5) is equal to or more than 1.
摘要:
A mobile system for dispensing cryogenic liquid to a use point includes a bulk tank containing a supply of cryogenic liquid and a high pressure sump in communication with the bulk tank so as to receive cryogenic liquid therefrom. A heat exchanger is in communication with the sump and selectively receives and vaporizes a portion of cryogenic liquid from the sump. The resulting vapor is directed to the sump so as to increase the pressure therein. A pressure builder is in circuit between the sump and the bulk tank. The pressurized cryogenic liquid may be dispensed from the sump via a dispensing hose or directed to the pressure builder so as to pressurize the bulk tank. If the latter is selected, pressurized cryogenic liquid is dispensed from the bulk tank via a second dispensing hose. Operation of the system valves is automated by a controller.

A method is described for preparing mixtures of salts and/or other substances in general, including calcium and magnesium salts with carbon dioxide in pressurized containers, for the purpose of producing systems for the delivery of said mixtures in soluble form ant at a predetermined and constant saline concentration, for a wide variety of applications. The mixtures containing the substances are prepared in a stirred reactor under a pressure of carbon dioxide, and from there are brought into use after they have been transferred into containers that are suitable for maintaining the internal pressure generated by the carbon dioxide in the form of vapour, in the form of a liquid/vapour mixture or under supercritical conditions.
摘要:
A dispensing nozzle has a body (10) adapted to be connected to a supply of liquidified petroleum gas by connector piece (11) and to a vehicle gas tank by a threaded insert (19) in swivel nut (15). Gas is applied to the reservoir within the valve body (24) through the connector piece (11) and is delivered through a main valve having a valve seat (33) and a piston valve (23). Piston valve (23) and valve cylinder (22) form a dash pot which is pressurised by gas flowing through passageway (37). There is an annular gap between the piston valve (24) and the valve cylinder (22) through which gas will bleed as soon as the valve (23) is cracked from its seat (33) to reduce the pressure in the dash pot which enables easy opening of the main valve. The swivel nut (15) is locked in position by pin (20) which engages one of a plurality of recesses (21) at its rear face when the nozzle is open.

The invention is directed to a method for calculating the remaining usage time of a gas cylinder equipped with a pressure reducer, the method comprising the following steps: (a) measuring the pressure of the gas in the cylinder; (b) calculating the variation of pressure of the gas in the cylinder over time while gas is outputted; (c) calculating a remaining usage time Tr based on the measured pressure in the cylinder and the calculated variation of pressure. Step (c) takes into account characteristics of the pressure reducer relative to variations of its nominal flow rate along the decrease of its inlet pressure while emptying the cylinder.
