Cryogenic fluid management

A method comprising:

• admitting cryogenic fluid from a storage tank to a first pressure tank and causing the cryogenic fluid to be heated to convert it into gas form in the first pressure tank;
• admitting the fluid in gas form from the first pressure tank through a first ejector, such that the fluid in gas form acts as a motive fluid to cause evacuation of a second pressure tank as it passes through the first ejector;
• after the second pressure tank has been evacuated, admitting cryogenic fluid from the storage tank to the second pressure tank and causing the cryogenic fluid to be heated to convert it into gas form in the second pressure tank, and
• admitting the fluid in gas form from the second pressure tank through either the first ejector or a second ejector, such that the fluid in gas form acts as a motive fluid to cause evacuation of the first pressure tank as it passes through the first or the second ejector.

A non-transitory computer readable medium having stored thereon a set of computer readable instructions that, when executed by at least one processor, cause an apparatus to at least:

• admit cryogenic fluid from a storage tank to a first pressure tank and cause the cryogenic fluid to be heated to convert it into gas form in the first pressure tank;
• admit the fluid in gas form from the first pressure tank through a first ejector, such that the fluid in gas form acts as a motive fluid to cause evacuation of a second pressure tank as it passes through the first ejector;
• after the second pressure tank has been evacuated, admit cryogenic fluid from the storage tank to the second pressure tank and cause the cryogenic fluid to be heated to convert it into gas form in the second pressure tank, and
• admit the fluid in gas form from the second pressure tank through either the first ejector or a second ejector, such that the fluid in gas form acts as a motive fluid to cause evacuation of the first pressure tank as it passes through the first or the second ejector.
