Abstract
Methods and systems for reducing the pressure of a hydrocarbon-containing stream so as to provide a cooled, reduced-pressure hydrocarbon-containing stream are provided. Facilities as described herein utilize a single closed-loop mixed refrigeration system in order to facilitate transportation, loading, and/or storage of a liquefied hydrocarbon-containing material at or near atmospheric pressure. In some aspects, the facilities can include at least one separation device for removing lighter components from the feed stream, which may separately be recovered as a vapor product for subsequent processing and/or use.
