    摘要: A process separates a multicomponent feed by distillation into at least one stream enriched in the most volatile component, one stream enriched in the least volatile component, and one stream enriched in a component of intermediate volatility. In one embodiment, the process produces an argon-enriched stream from a cryogenic air separation process. The distillation system includes at least one distillation column that produces a nitrogen-enriched stream from the top of the column, an oxygen product stream from the bottom of the column, and an argon-enriched stream from a partitioned section. The geometry of the partitioned section minimizes vapor and liquid distribution, and includes a vertical separating element and an end separating element to isolate the partitioned section from the intermediate distillation section. The equivalent diameter (De) of the partitioned section is at least 60% of the ideal diameter (Di) of the partitioned section, wherein the equivalent diameter is defined as four times the cross sectional flow area enclosed by the vertical separating element divided by the perimeter formed by the vertical separating element, and the ideal diameter (Di) is the diameter of a circle which has the same cross sectional flow area as that cross sectional flow area which is enclosed by the vertical separating element.

    摘要: A sulfur recovery system for recovering sulfur from a sulfur plant feed stream including a first sulfur removal system and a second sulfur removal system. The system includes a sulfur plant feed inlet to the first sulfur removal system, the sulfur plant feed inlet being capable of providing a sulfur plant feed stream at a first pressure. One or more oxidizing gas inlets are arranged and disposed to combine at least one oxidizing gas stream with the sulfur plant feed stream to form a combustion gas for combustion in the first sulfur removal system at a second pressure. A flow restriction device is operably configured to control an operating pressure in one or both of the first sulfur removal system and the second sulfur removal system. A gas processing plant and method for recovering sulfur from a sulfur plant feed stream are also disclosed.

    摘要: A system is set forth to increase the capacity of an LNG-based liquefier in a cryogenic air separation unit wherein, in a low production mode, the nitrogen that is fed to the LNG-based liquefier consists only of at least a portion of the high pressure nitrogen from the distillation column system while in a high production mode, a supplemental compressor is used to boost the pressure of at least a portion of the low pressure nitrogen from the distillation column system to create additional (or replacement) feed to the LNG-based liquefier. A key to the present invention is the supplemental compressor and the associated heat exchange equipment is separate and distinct from the LNG-based liquefier. This allows its purchase to be delayed until a capacity increase is actually needed and thus avoid building an oversized liquefier based on a speculative increase in liquid product demand.
