Abstract:
LNG vapor from an LNG storage vessel is absorbed using C3 and heavier components provided by a fractionator that receives a mixture of LNG vapors and the C3 and heavier components as fractionator feed. In such configurations, refrigeration content of the LNG liquid from the LNG storage vessel is advantageously used to condense the LNG vapor after separation. Where desired, a portion of the LNG liquid may also be used as fractionator feed to produce LPG as a bottom product.
Abstract:
A plant includes an absorber (103) that operates in a gas phase supercritical region and removes an acid gas from a feed stream (9) at high recovery of the feed stream (10) while producing a high purity acid gas stream (36). Particularly preferred plants include gas purification plants that receive a feed gas with at least 5 mol % carbon dioxide at a pressure of at least 3000 psi.

Abstract:
A syngas treatment plant is configured to remove sulfurous compounds and carbon dioxide from shifted or un-shifted syngas in a configuration having a decarbonization section and a desulfurization section. Most preferably, the solvent in the decarbonization section is regenerated and cooled by flashing, while the solvent is regenerated in the desulfurization section via stripping using external heat, and it is still further preferred that carbonylsulfide is removed in the desulfurization section via hydrolysis, and that the so produced hydrogen sulfide is removed in a downstream absorber.
Abstract:
Contemplated plants comprise an acid gas removal unit (102) that receives a compressed gas from an injection gas compressor (107), wherein acid gas is removed from the compressed gas in the acid gas removal unit (102) at a pressure of about of above pipeline pressure.

Abstract:
A filter system has a first filter from which solvent is recovered in a cleaning cycle using a rinse fluid in forward flow, and from which particulates are removed using flush gas in reverse flow. At least part of the solvent and the flush gas are recycled to the system and in still further preferred aspects, filtration of the solvent continues during the cleaning cycle via a bypass circuit through which the solvent is routed to a second filter.
Abstract:
A device for verifying the calibration of an infrared sensor includes a body configured to be placed in orbit. The body defines a spin axis and an outer surface. The outer surface has an infrared radiant intensity that is substantially independent of the viewing angle between the spin axis of the body and the infrared sensor. The device may be used for on-orbit verification of the calibration coefficients associated with each pixel of an infrared sensor, including linearity calibration and verification of the resolution capability of the sensor. The calibration coefficients may be verified over the entire sensing capability range of the infrared sensor. After a thermal model of the device is developed, the device operates passively and provides a known source of infrared radiation observable during the device's entire orbital lifetime. The device may be designed to automatically de-orbit from space after a predictable time in orbit.
