"PROCESS FOR MANUFACTURING A MULTI-COMPONENT PRESSURE LIQUID, METHOD FOR CARRYING A RICH HYDROCARBON COMPOSITION AT LEAST ONE OF C ~ 1 ~ OR C ~ 2 ~, METHOD FOR TREATING A PRESSURE PROCESSED TRANSPORTATION POWER LOAD MANUFACTURING A LIQUID NATURAL GAS CURRENT, MANUFACTURING A PRESSURED NATURAL LIQUID GAS, AND FOR TRANSPORTING NATURAL GAS AND MULTI-COMPONENT PRESSURE LIQUID ". The invention relates to a process for the manufacture of a pressurized multicomponent liquid from a pressurized multicomponent stream (20), such as natural gas, which comprises C ~ 5 + ~ components and at least one C ~ 1 ~, C component. ~ 2, ~ C ~ 3 ~ OR C ~ 4 ~. The process selectively removes (12) from the multicomponent stream one or more of the C ~ 5 + ~ components expected to crystallize at the selected temperature and pressure of the pressurized multicomponent liquid product and leaves at least one C ~ 5 + ~ component in the multicomponent stream. The multicomponent stream is then liquefied (14) to produce a pressurized liquid substantially free of crystallized C5 + + components. Removal of C ~ 5 + ~ components may be by selective fractionation or crystallization.
