Problems solved by technology

Unfortunately, pipeline networks can represent a significant investment, and are generally used only in situations where the natural gas is traveling a relatively short distance.
Natural gas condenses to its liquid state at about −260° F., or approximately −162° C. Accordingly, ...

Embodiment Construction

[0018]One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0019]When introducing elements of various embodiments of the present invention, the articles “a,”“an,”“the,” and “said” are intended to mean that there are one or more of the ...

Abstract

In an embodiment, a method includes cooling a fluid along a fluid path using a vapor compression refrigeration cycle; cooling the fluid along the fluid path using at least one cryocooler of a cryogenic cooling phase; expanding the fluid during cooling within the cryogenic cooling phase, after cooling in the cryogenic cooling phase, or a combination thereof, such that a temperature and pressure of the fluid are reduced to generate a fluid stream having both a vapor phase and a liquid phase; and condensing the vapor phase. The fluid may be a natural gas.

Description

BACKGROUND[0001]Natural gas, when isolated from natural sources (e.g., underground in naturally occurring reservoirs), generally includes a mixture of hydrocarbons. The major constituent in these hydrocarbons is methane, which is generally referred to as natural gas in commerce. Natural gas is useful as a source of energy because, among other things, it is highly combustible. One particularly desirable characteristic of natural gas is that it is generally considered to be the cleanest hydrocarbon for combustion. Because of this, natural gas is often used as fuel in a wide variety of settings, including heaters in residential homes, gas stoves and ovens, dryers, water heaters, incinerators, glass melting systems, food processing plants, industrial boilers, among numerous others. Generally, natural gas (e.g., untreated or raw natural gas) removed from reservoirs is processed and cleaned prior to entering pipelines that eventually feed the gas to homes and industrial plants. For exampl...
