The present invention relates to a supply station jointly storing a low-temperature-liquefied combustible gas, in particular natural gas, and liquid nitrogen and designed for supplying each component separately or jointly as needed to a vehicle, the supply station being present on the vehicle, the station comprising at least a first storage tank for storing said liquefied combustible gas; and at least a second storage tank for storing said liquid nitrogen and at least one heat-transmitting connection element between the at least one first storage tank and the at least one second storage tank, which connection element is designed so that the combustible gas can be cooled, or can be maintained at a temperature below its boiling point, directly or indirectly by the liquid nitrogen.

Method for the refrigerated transportation of a stock in a vehicle implementing a liquid combustible gas tank and a liquid nitrogen tank

The process and device according to the invention make it possible to reduce the pressure build-up in the head space as a function of the quantity of inflow medium. It also makes it possible to maintain or create defined flow conditions in the head space gas. This is accomplished by measuring the quantity of gaseous and/or liquid inflow medium and then venting the head space gas as a function of the quantity of inflow medium.

Process and device to regulate the inner pressure of a tank and/or to

In processes for high pressure extraction, a gaseous solvent under high pressure is conducted through an extractor filled with solid material and in this process takes on organic components from the solid materials. These are subsequently separated in a separator and the solvent is again delivered to the extractor. In particular, when gas mixtures having a reduced solvating power are used as solvent to increase the selectivity of the components to be dissolved out, high gas throughputs become necessary to produce a certain amount of product. In order to reduce the high gas throughputs, the solid materials are soaked with a gaseous solvent under high pressure without gas extraction before the circulation process begins. The solvent composition as well as the soaking conditions may deviate from the extraction conditions. In this process, prior to the extraction stage, the solid material in the extractor is soaked with a gaseous solvent under high pressure without the occurrence of a gas flow.
