摘要:
A process for recovering liquefied C3 compounds from a natural gas stream containing C3 compounds which comprises (a) chilling the natural gas stream under conditions sufficient to liquefy the natural gas, whereby a mixture comprising liquid natural gas (LNG) and liquid C3 compounds is formed; (b) fractionating the mixture comprising liquid natural gas (LNG) and liquid C3 compounds in a separation zone under sub-atmospheric pressure and under conditions predetermined to vaporize a significant portion of the natural gas present while retaining the C3 compounds as a liquid fraction; and (c) recovering separately from the separation zone natural gas and liquid C3 compounds.

摘要:
An LED light engine includes a flexible electrical cable and a plurality of LEDs. The flexible electrical cable includes first, second and third electrical conductors and an electrically insulating covering for the electrical conductors. The conductors are arranged substantially parallel with one another having an insulating material therebetween. A first LED including a first lead electrically connects to the first electrical conductor and a second lead of the first LED electrically connects to the second conductor. A second LED includes a first lead electrically connected to the second electrical conductor and a second lead electrically connected to the third electrical conductor. A third LED includes first and second leads electrically connected to the second conductor. The third LED is interposed between the first LED and the second LED.
摘要:
A method of protecting a surface of a device from residual polishing compound comprises applying a thin barrier layer of coating material to the surface of the device; polishing the surface with a polishing compound; rinsing the polishing compound from the device; and removing the thin barrier layer from the surface of the device to remove the residual polishing compound.
摘要:
A universal CAD-neutral data management system capable of two-way exchange of information between a CAD-neutral database and any one of a variety of proprietary CAD graphics platforms. An updateable CAD-neutral database includes parameter descriptions arrayed against parameter values and may further include parameter type information.
摘要:
A process for condensing a C3-C4 hydrocarbon vapor which comprises contacting the C3-C4 hydrocarbon vapor with a heat exchanger surface which is cooled by contact with LNG and recovering a liquefied C3-C4 product therefrom.
