| 24 | Separation of multi-component mixtures | US818337 | 1977-07-22 | US4124496A | 1978-11-07 | Donald R. Cummings |
| An improvement in the separation of a multi-component mixture, especially a well head stream, into gaseous and liquid phases by multi-component flash separation at reducing pressures, comprises recycling at least a part of the gaseous fraction recovered from a stage after the first stage to a preceding stage, and preferably the immediately preceding stage, to mix with the liquid phase which is separated in said preceding stage and at substantially the pressure of said preceding stage. This (a) increases the gas/liquid ratio in each stage, the amount of liquid recovered from the last stage and the proportion of medium-boiling components therein; (b) results in more gas being available from the higher pressure stages and (c) yields gases having narrower boiling ranges. Three separation stages are preferred and pipeline gas, crude LPG and a local fuel gas to supply the energy requirements of the separation can be derived from the gaseous fractions recovered from the separation stages. | ||||||
| 25 | Process and apparatus for liquefying natural gas | US593222 | 1975-07-07 | US4012212A | 1977-03-15 | Ludwig Kniel |
| There is disclosed a novel process and apparatus for liquefying a hydrocarbon gas under a pressure greater than the critical pressure thereof wherein the gas is first expanded to below the critical pressure thereof to permit the facile separation of C.sub.5 and heavier hydrocarbons with the lighter components being re-pressurized to above the critical pressure thereof by such expanding gas prior to the further cooling of such re-compressed lighter components for eventual liquefaction. | ||||||
| 26 | Lng expander cycle process employing integrated cryogenic purification | US3724226D | 1971-04-20 | US3724226A | 1973-04-03 | PACHALY R |
| A process and apparatus for the liquefaction of natural gas wherein raw feedstock is cryogenically fractionated to remove essentially all of the carbon dioxide and C5 hydrocarbons therefrom, and wherein the cryogenically purified feedstock is cooled and liquefied under pressure in a cryogenic heat exchanger. The pressurized cold liquid from the heat exchanger is isenthalpically expanded to reduce the pressure and further cool the liquid while at the same time flashing a minor gas fraction. Refrigeration for the liquefaction of the natural gas is supplied by a circulating refrigerant stream which is compressed and workexpanded to obtain the necessary cooling. The minor flash gas portion of the liquefaction step is commingled with the circulating refrigerant stream so that the analysis of the refrigerant stream is always rich in the lighter portions of the liquefaction stream, thus aiding in maintaining refrigeration temperature differentials to drive the liquefaction step. The work-expanded refrigerant portion undergoes a compression cycle and is work-expanded in a series of expansion turbines. The expansion turbines furnish at least part of the power necessary to drive the compressor system in the refrigerant gas cycle.
