Abstract
1. Способ выделения водорода на палладиевой мембране с рекуперацией тепла, предусматривающий подогрев водородсодержащего газа, поступающего после очистки от воды и диоксида углерода и содержащего в качестве примесей оксид углерода, метан, азот и остатки диоксида углерода, до температуры 400-800°C и последующее выделение чистого водорода путем диффузии через палладиевую мембрану с отводом продувочного газа, отличающийся тем, что очищенный от воды и основной части диоксида углерода водородсодержащий газ до поступления на палладиевую мембрану разделяют на два потока, один из которых подогревают в теплообменнике за счет передачи тепла от выходящего после мембраны выделенного водорода, а второй поток нагревают во втором теплообменнике за счет передачи тепла от основной части продувочного газа, отводимого от мембраны, затем оба потока водородсодержащего газа вновь объединяют, догревают до требуемой температуры в газовом нагревателе, снабженном горелкой, дымовыми газами, образующимися при сжигании в горелке другой части продувочного газа, после чего нагретый водородсодержащий газ подают на палладиевую мембрану для выделения из него чистого водорода, а продувочный газ, отводимый от мембраны, разделяют на два потока, один из которых подают на горелку в качестве топлива, а второй поток направляют во второй теплообменник в качестве греющей среды, после чего возвращают в основной процесс получения синтез-газа. ! 2. Способ по п.1, отличающийся тем, что разделение водородсодержащего газа на два потока осуществляют в соотношении, преимущественно пропорциональном соотношению количеств тепла, вносимых в первый и второ 1. The method of hydrogen evolution on a palladium membrane with heat recovery, providing for the heating of a hydrogen-containing gas coming from water and carbon dioxide after purification and containing carbon monoxide, methane, nitrogen and carbon dioxide residues as impurities, to a temperature of 400-800 ° C and subsequent the release of pure hydrogen by diffusion through a palladium membrane with a purge gas outlet, characterized in that the hydrogen-containing gas purified from water and the main part of carbon dioxide before entering the palladium membrane well, they are divided into two streams, one of which is heated in the heat exchanger due to heat transfer from the released hydrogen leaving the membrane, and the second stream is heated in the second heat exchanger due to heat transfer from the main part of the purge gas discharged from the membrane, then both hydrogen-containing gas flows again combine, warm up to the required temperature in a gas heater equipped with a burner, flue gases generated when another part of the purge gas is burned in the burner, after which the heated hydrogen content The gas is fed to the palladium membrane to separate pure hydrogen from it, and the purge gas discharged from the membrane is divided into two streams, one of which is supplied to the burner as fuel, and the second stream is sent to the second heat exchanger as a heating medium, after which return to the main process for producing synthesis gas. ! 2. The method according to claim 1, characterized in that the separation of the hydrogen-containing gas into two streams is carried out in a ratio mainly proportional to the ratio of the amounts of heat introduced into the first and second
