TRANSFER OF NATURAL GAS DIRECT FROM A PIPELINE TO LIQUID STORAGE

This invention relates to a method of moving natural gas mixes directly from a high pressure pipeline into a marine or similar liquid containment or transport system. During the loading process a select rich natural gas mixture is transformed into a liquid state without the need for an intermediate traditional LNG processing facility. The liquid mixture results from an induced phase change caused by releasing high pressure NGL enriched natural gas from a pipeline or storage into a lower pressure containment system. The pressures of adjacent gas pipelines are utilized to assist with loading and unloading the stored liquid. Increase in constituent NGLs, chilling or pressurizing can further increase the desired liquid storage density. The work expands beyond existing teachings of the authors and others. The density of the natural gas component held in the liquid here exceeds those of PLNG or CNG under these selected conditions.

METHOD OF TRANSPORT AND DISTRIBUTION OF HELIUM BY MEANS OF MOBILE BULK STORAGE TANKS

Summary Helium is transported and distributed in mobile bulk storage tanks (1) and filled at filling stations (3) into smaller consumer tanks (11). The contents of the tank takes up heat continuously from the surroundings, which leads to a continuous rise in temperature and pressure of the contents of the tank, so that the original liquid helium above a critical pressure turns into a singlephase supercritical fluid. The bulk storage tank (5) may at need be brought to a recooling station (2) which by a recooler group (4) which exhibits a closed cooling circuit cools a heat-exchanger (29) which cools the contents of the bulk storage tank (5). Through the extraction of heat the contents of the bulk storage tank (5) may be cooled as often as desired to a usually standardized temperature. (Figure 1) ...

Refrigeration process for liquefaction of natural gas.

A PROCESS IS DISCLOSED FOR CONVEYING GAS STREAM RICH IN METHANE, SUCH AS NATURAL GAS. IN THE FIRST STEP OF THE PROCESS, GAS IS SUPPLIED TO A PIPELINE AT AN ENTRY PRESSURE THAT IS SUBSTANTIALLY HIGHER THAN THE OUTPUT PRESSURE OF THE PIPELINE. THE DROP IN PRESSURE IN THE PIPELINE CAUSES A LOWERING OF THE GAS TEMPERATURE, PREFERABLY TO A TEMPERATURE BELOW ABOUT -29°C. (-20°F.). THE ENTRY PRESSURE OF THE GAS TO THE PIPELINE IS CONTROLLED TO ACHIEVE A PREDETERMINED OUTPUT PRESSURE OF THE GAS FROM THE PIPELINE. OUTPUT GAS FROM THE PIPELINE IS THEN LIQUEFIED TO PRODUCE LIQUEFIED GAS HAVING A TEMPERATURE ABOVE ABOUT -112°C. (-170°F.) AND A PRESSURE SUFFICIENT FOR THE LIQUID TO BE AT OR BELOW ITS BUBBLE POINT TEMPERATURE. THE PRESSURIZED LIQUEFIED GAS IS THEN FURTHER TRANSPORTED IN A SUITABLE CONTAINER. (

Condensation system for expansion of untreated brönnström from an offshore gas or gas condensate field

In a method of condensing an unprocessed well stream from an offshore gas or gas condensate field the well stream taken from one or more wellheads is cooled and directly expanded, isentropically, or near isentropically, to a state in which the pressure is close to that of a storage tank. Part of the well stream is condensed and condensed fractions thereof is drawn off the expander and fed to the storage tank along with condensation products from the exit of the expander. Hence, without any preprocessing, a condensed well stream product is produced which comprises a mixture of liquids and solids which is collected in the storage tank for transport therefrom to land. A system for carrying out the method is also disclosed. The invention makes the condensation of an unprocessed well stream possible without any preprocessing thereof, such as extraction of solid particles, e.g. sands, removal of water, cleaning or drying. Thus, by means of the invention smaller gas or gas condensate fields can be developed in a more cost efficient way.
