A design for equipment and process for reliquefaction of LNG boiloff gas, primarily for shipboard installation, has high thermodynamic efficiency and lower capital cost, smaller size (volume, footprint), lower weight, and less need for maintenance than systems utilizing the prior art. The main refrigerant gas compressor is reduced to a single stage turbocompressor. Optional elements include: compression of boiloff gas at ambient temperature; compression of boiloff gas in one or two stages; turboexpansion of refrigerant gas incorporating one or two turboexpanders; turboexpander energy recovery by mechanical loading, compressor drive, or electric generator; refrigerant sidestream for cooling at the lowest temperatures.

Nitrogen gas at a single pressure is produced from a two-column cryogenic distillation of air. The bottoms liquid product from the high pressure column is divided into portions, at least one of which does not enter the low pressure column as a feed stream. By these means, a portion of an oxygen-rich stream is removed from the distillation, further enhancing nitrogen recovery and achieving low specific energy consumption for nitrogen product.

Nitrogen gas at a single pressure is produced from a two-column cryogenic distillation of air. The bottoms liquid product from the high pressure column is divided into two portions, one of which is vaporized and then turboexpanded before its entry into the low pressure column as a feed stream. By these means, no stream bypasses the double distillation process, further enhancing nitrogen recovery and achieving low specific energy consumption for nitrogen product.

A method and apparatus for producing a ultra-high purity oxygen product in which a nitrogen generator is operated to produce nitrogen and an oxygen rich fraction as column bottoms. Part of the oxygen rich fraction can be further processed at column pressure within rectification column to produce a tower overhead lean in hydrocarbons such as methane, acetylene, propane and propylene. After liquefaction in a head condenser of the rectification column, part of the condensate is further processed in a stripping column to produce an ultra-high purity liquid oxygen column bottoms which can be extracted as product.

A method and apparatus for separating air in which a compressed and purified air stream is cooled in a main heat exchanger. Thereafter, the compressed and purified air is separated in a distillation column system to produce product streams. The product streams warm within the main heat exchanger by indirectly exchanging heat with the compressed and purified air stream. One or more of the product streams is distributed to a plurality of vortex tubes at successively warmer temperatures so that warm and cold streams produced thereby become successively warmer and one or more of the warm streams has a temperature warmer than that of said compressed and purified air stream upon its introduction into said main heat exchanger. All but the warm stream(s) having the warmer temperature are recycled back to said main heat exchanger to participate in the indirect heat exchange and heat is rejected by discharging said warm stream(s) so that heat is rejected at the warmer temperature and refrigeration is produced.

A process and apparatus for producing a gaseous oxygen product at a delivery pressure so as to contain a low concentration of heavy impurities in which compressed and purified air is cooled in a main heat exchanger to near dew point temperatures and then introduced into an air separation unit designed to rectify the air into a liquid oxygen fraction. The air separation unit comprises high and low pressure columns operatively associated with one another in a heat transfer relationship by provision of a condenser-reboiler. The liquid phase of the air being separated becomes increasingly more concentrated in heavy impurities as it descends within the low pressure column so that liquid oxygen collected in the sump of the condenser-reboiler becomes concentrated in the heavy impurities and the liquid phase flowing into the sump contains a low concentration of the heavy impurities. A product stream is withdrawn from the liquid phase before it reaches the sump and is pumped to the delivery pressure and then vaporized within the main heat exchanger. A purge stream of liquid oxygen from the sump is removed so that the impurity concentration level within the liquid oxygen does not reach its solubility limit.
