Method and arrangement for avoiding uncontrolled outflow or overflow of gas when transferring boiling liquids and pressure gases

摘要

The invention relates to a method of avoiding uncontrolled outflow and overflow of gas when transferring boiling liquids and pressure gases, such as, for example, liquefied gas, in particular from tankers into storage tanks. The gas pressure in the storage tank is set in such a way that a positive pressure preventing subsequent boiling of the liquid phase in the tank is maintained, and only if the positive pressure is exceeded does gas flow over from the storage tank into the tanker until the predetermined positive pressure is reached again.
