TEST BENCH FOR PROCESS OF REPLACING METHANE WITH CARBON DIOXIDE IN METHANE HYDRATE Russian patent published in 2025 - IPC G01N7/14 

FIELD: measuring.

SUBSTANCE: invention relates to experimental equipment and can be used to study the process of replacing methane with carbon dioxide in methane hydrate. Test bench comprises reactor (1) made in the form of a steel vertical cup with double walls, between which a cavity is formed, which is connected by pipelines to thermostat (2). Cover of reactor (1) contains temperature sensor (3), funnel (16) equipped with valve (17), outlet valve (4) and a branch pipe for gas discharge into the atmosphere, which is equipped with safety valve (5) and pressure sensor (6). Temperature (3) and pressure (6) sensors are connected to conversion unit (7) connected to personal computer (8). Inside reactor (1) along its bottom there is pipe (9) in which holes are made at equal distance from each other. Ends of pipe (9) are brought out through walls of reactor (1). One end of pipe (9) is connected to cylinder (12) filled with methane, and the other end is connected to cylinder (15) filled with carbon dioxide. Internal volume of reactor (1) is connected to vacuum pump (20). A sampling channel is connected to gas pipeline (18), which is connected through valve (21) to gas chromatograph (22) connected to personal computer (8). Vacuum pump (20) is connected to methane storage tank (25) and to separator (28). Separator (28) is connected to methane storage tank (25) and to carbon dioxide storage tank (30). Vacuum pump (20) is brought to atmosphere through gas line (32).

EFFECT: investigation of the process of substitution of methane with carbon dioxide in methane hydrate.
