A dual-mode LNG liquefier arrangement that is configurable to operate in a first mode broadly characterized as a low pressure, liquid nitrogen add LNG liquefier without turbo-expansion or a second mode broadly characterized as a low pressure, liquid nitrogen add LNG liquefier with turbo-expansion.

Dual mode Liquefied Natural Gas (LNG) liquefier

A modular, aerogel-based vacuum insulated pipe section comprising an outer conduit; an inner conduit concentrically disposed within the outer conduit with aerogel insulation and a condensable gas being disposed in the insulation space between the concentric conduits. As a stand-alone pipe section, the insulation space is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit, the condensable gas condenses and the pressure within the insulation space is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section further includes a coupling arrangement disposed on a first end of the inner conduit and a second end of the inner conduit, the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.
