Abstract: Systems and methods for liquefying a gaseous fluid that comprises at least 50% by volume methane into a liquefied fluid that comprises at least 85% by volume methane. Processing can include increasing a pressure of the incoming gaseous fluid to between 10 and 50 bar; pre-treating the gaseous fluid using membrane filtering to a retentate stream having a methane content of at least 85% by volume; liquefying the retentate stream by cryogenic cooling to a temperature between ?100° C. and ?140° C.; flashing the liquefied fluid into a container; retrieving processed liquid fluid at a first container level at a pressure of between 1 and 10 bar, a temperature of between ?120° C. and ?160° C., and a methane concentration of at least 85% by volume into a storage device; and retrieving a slurry flow comprising solid CO2 and water ice at a second container level below the first container level.

Abstract: The invention provides a sensing device that can be incorporated in a construction element for a toy construction set to allow new use of construction elements, for instance tracking the construction process. Sensing device comprises a carrier comprising a top surface provided with a series of top coils, a bottom surface with a series of bottom coils at a distance from said top coils, the sensing device further comprising a data processor functionally coupled with a memory for storing a status, said data processor comprises a computer program which controls and reads currents through each of said top and bottom coils and storing them in memory, thereby tracking status for each of said top and bottom coils.
