A process to recover higher boiling synthesis gas component substantially free of hydrogen comprising partial condensation of a synthesis gas reaction stream, defined stripping of hydrogen out of the resulting liquid, and fractional distillation of the resulting fluid.

Process to recover hydrogen-free higher boiling synthesis gas component

A process to produce methane gas product with reduced product compression requirements comprising pumping liquid methane from a cryogenic nitrogen rejection plant to a high pressure thereby utilizing available excess refrigeration, and rewarming the pumped liquid methane product against incoming process streams.

Process to produce high pressure methane gas

A process to produce cold helium gas suitable for use as a feed to a helium liquifier comprising employing refrigeration from a nitrogen rejection unit to reduce the temperature of the helium gas just prior to its passage to the liquifier thus enabling a reduction in the liquifier energy requirement.

Process to produce cold helium gas for liquefaction

A process to produce helium gas from a feed to a nitrogen rejection unit comprising employing refrigeration from the nitrogen rejection unit to increase the recovery of helium by cooling crude helium prior to further processing.

Process to produce helium gas

A selected paraffinic or olefinic liquid is used to scrub acetylene from a minor gas fraction of uncondensed gas from a hydrocarbon feed mixture containing ethylene, hydrogen, acetylene and methane. Hydrogen product gas is separated and recovered from said minor gas fraction. The major gas fraction is processed without said acetylene removal operation, but under elevated pressure conditions effectively avoiding acetylene solidification during the separation and recovery of an ethylene-enriched liquid.

Acetylene removal in ethylene and hydrogen separation and recovery

Process for solid refuse disposal in which a vertical shaft furnace is maintained at 30-250 psia, part of the recycle-condensate is filtered to form liquid waste a portion of which is incinerated with a minor part of the product gas to form hot exhaust gas used to heat feed water in steam boiler zone, and energy from the resulting steam is recovered as part of the process energy requirement.
