Dynamic Ullage Control System for a Cryogenic Storage Tank |
摘要 |
A dynamic system for determining an optimal liquid fill level and ullage space for a cryogenic liquid storage tank based on the temperature of the liquid being dispensed into the tank, and the desired operating pressure for an application. A means for selecting a desired operating pressure, such as a dial, is located external to the storage tank. A temperature sensor measures the temperature of the cryogenic liquid being dispensed. An optimal fill level and ullage space is calculated, and communicated to a liquid level sensor and flow control valve. |

1. A system for controlling the ullage space of a cryogenic storage tank comprising:
a) at least one insulated storage tank capable of receiving and storing a liquid at a cryogenic temperature and an initial pressure; b) a means for selecting a desired operating pressure; c) at least one device for measuring temperature of a cryogenic liquid; d) at least one device for measuring the cryogenic liquid depth inside the storage tank; e) a means for controlling flow into the storage tank; whereby flow into the storage tank is stopped at a calculated optimal fill level. |
