摘要： A gas cylinder monitoring system comprising a gas cylinder for receiving and distributing gas. A flow control valve is associated with the gas cylinder and operable to allow or prevent the flow of gas from the cylinder. A monitor is provided for monitoring a signal from an input device associated with the flow control valve. The monitor has an environmental parameter sensor for detecting the presence or absence of a selected environmental parameter in the vicinity of the cylinder. The environmental parameter sensor is connected to the monitor for transmitting an environmental status signal thereto. A removable cover is provided for covering both the flow control valve and the environmental parameter sensor such as to only allow access to the flow control valve when the cover is removed. A transmitter is also provided for transmitting a signal, obtained by the monitor from the input device, to a receiver.

摘要： A heat exchanger includes a core tube extending in a shell space, several tubes wound around the core tube, and a liquid distributor. The liquid distributor is arranged above the tubes in the shell space and applies a liquid phase of a first medium to the tubes. The liquid distributor has distributor arms projecting in the radial direction from the core tube, an annular channel extending above the distributor arms in a circumferential direction of the shell and a collector tank formed by the core tube. The annular channel and the collector tank are each designed to collect the first medium. The distributor arms form at least one first container and at least one second container separated from the first container.

摘要： Systems and methods for enhanced or improved oil recovery includes injecting a Y-Grade NGL enhanced oil recovery fluid through an injection well into a hydrocarbon bearing reservoir to mobilize and displace hydrocarbons. The Y-Grade NGL enhanced oil recovery fluid comprises an unfractionated hydrocarbon mixture. Simultaneously and/or subsequently, a mobility control fluid is injected into the hydrocarbon bearing formation. Hydrocarbons from the hydrocarbon bearing reservoir are produced through a production well or the same injection well.
