US 12,669,222 B2 · Boil-off management system

Abstract

A boil-off management system for a cryotank includes a boil-off conduit which is fluidically connectable to a cryotank via a boil-off valve. The boil-off management system further includes an air feed conduit and a mixing chamber for mixing a first medium (e.g., hydrogen) flowing in through the boil-off conduit with a second medium (e.g., air and/or oxygen) flowing in through the air feed conduit. A catalytic converter is arranged downstream of the mixing chamber and an outlet downstream of the catalytic converter. At least one enrichment apparatus is provided and configured to temporarily increase the proportion of the first medium flowing in through the boil-off conduit in relation to the second medium flowing in through the air feed conduit at the catalytic converter.

Dependent claims

A boil-off management system for a cryotank, comprising:

a boil-off conduit having a boil-off valve which is fluidically connectable to a cryotank, through which is received a first medium that includes hydrogen;
an air feed conduit, through which is received a second medium that includes air and/or oxygen;
a mixing chamber configured to mix the first medium with the second medium;
a catalytic converter arranged downstream of the mixing chamber;
an outlet arranged downstream of the catalytic converter;
and
at least one enrichment comprising a control unit configured to detect an existence of an enrichment criterion, temporarily increase a proportion of the first medium in relation to the second medium flowing at the catalytic converter, and stop an increase in the proportion of the first medium in relation to the second medium flowing at the catalytic converter.
