摘要： The invention relates to a compact catalytic reactor comprising at least three plates with at least one area of millimetric channels on each plate, promoting heat exchange, and at least one distribution area upstream and/or downstream of the area of millimetric channels, the channels being separated by walls. The distribution areas are characterized by:the discontinuity of the walls along the distribution area on the side of the inflow of gaseous flows or on the side of the outflow thereof; andthe increase in the width of the walls along the distribution area on the side of the inflow of gaseous flows or on the side of the outflow thereof.

摘要： Plant and process for the production of liquid methane from a feed gas stream comprising at least methane and carbon dioxide. A feed gas stream is injected into a CO2 crystallizer in countercurrent fashion against a stream of predominantly liquid methane, thereby crystallizing amounts of carbon dioxide from the feed gas stream. Gaseous methane recovered from the CO2 crystallizer is liquefied at a liquefaction exchanger.

摘要： Process for producing biomethane from a biogas stream including methane, carbon dioxide and at least one impurity chosen from ammonia, volatile organic compounds, water, sulfur-based impurities (H2S) and siloxanes. A biogas stream is dried, the at least one impurity is at least partially removed by solidification and removal of the impurity. The methane and the carbon dioxide contained in the biogas obtained from the second step are separated so as to produce a biomethane stream and a CO2 stream.
