Apparatus and process for pre-liquefaction fluid processing for improved liquefaction operations
12535267 · 2026-01-27 · ·

An apparatus and process for processing of a fluid (e.g. hydrogen) for liquefaction can permit a reduction in power consumption and also an improvement in operational efficiency in flexibility. Embodiments can be configured to account for large variations in feed to be provided for liquefaction and also permit operational cost reductions associated with liquefaction processing so the overall power consumption and operational cost for liquefaction can be greatly reduced while also providing improved operational flexibility. For instance, embodiments can be configured to feed a fluid to multiple liquefiers of a train of liquefiers based on a pre-selected set of feed routing criteria for improving power consumption and providing greater operational flexibility for liquefaction operations.

SYSTEM FOR SUPPLYING CO2 GAS TO A FACILITY THAT REQUIRES CO2 OR A MIXTURE COMPRISING CO2, SUCH AS AN ABATTOIR OR A GREENHOUSE FOR CULTIVATING PLANTS
20260036363 · 2026-02-05 ·

A method for supplying CO.sub.2 gas to a site comprising a facility (20) that requires CO.sub.2 or a mixture comprising CO.sub.2, such as an abattoir or a greenhouse for cultivating plants, comprises the following steps: a boiler (4) capable of supplying hot water to the site is arranged within the site, the boiler carrying out the process of oxycombustion between a fuel (14) and pure oxygen (1), the oxygen that supplies the boiler being obtained from a liquid oxygen source present on the site; and some or all of the CO.sub.2 contained in the flue gas produced by the boiler is recovered by transferring heat between the flue gas and the liquid oxygen in an exchanger (2).
