Abstract

The pump (18) draws the liquefied carbon dioxide from the storage tank (4 or 6) and is passed through a regulated heater (20) and a filling valve (14) to the tank (26) for filling. The This container (26) was heated to Is controlled by a heater (32). Sensors (22,24) are used to indicate pressure and temperature. Of the contents of the container For each desired density there is a table showing the density. Relationship between pressure (Higher than the saturation pressure) with the temperature at that density Temperature selection (Which must be higher than the lowest temperature the container will Filled with liquid at the desired density but not necessarily higher than critical temperature) and control heaters (20 and 32). Tank and container space converge. Or close to the temperature when finished filling During the final process of packing The temperature rises slowly and the pressure (when the container is filled with liquid) rises relatively quickly. When the temperature and pressure are equal to the numbers in the table provided, close the filling valve (14), which cuts off the gas at the thickness. Tightly packed desired

Claims (1)

1. Methods for filling a container with liquefied gas at high pressure, the volume of the filled gas has a density. The procedure has a) to determine the pressure for the specific gas to be filled and by Only at the specified density Which each of these pressure has you The characteristic is associated with a single temperature greater than or equal to the saturation temperature at that density. B) Record this 1-to-1 relationship between pressure and saturation. Temperature in the right form Are intended to be referenced or used for comparison with the apparent pressure or temperature; c) gas supply to the tag:
