Claims (1)

Способ переработки природного газа с получением метанола, включающий отбор природного газа под давлением, нагревание, обессеривание газа, каталитическую паровую конверсию с получением конвертированного газа, утилизацию тепла, компремирование газа, синтез метанола с циркуляцией непрореагировавшего газа, рекуперацию тепла последнего с дальнейшим охлаждением в аппарате воздушного охлаждения и в холодильнике оборотной воды, отделение сконденсированного метанола, отличающийся тем, что исходный природный газ под давлением 30-45 атм делят на два потока в соотношении (75-85)/(25-15), первый основной технологический поток направляют на нагревание до 80oC в трубное пространство рекуперационного теплообменника высокого давления теплом циркуляционного газа с температурой 105-110oC, а второй поток после дросселирования и нагревания в метанольном подогревателе до температуры 50-60oC используют в качестве топливного газа.A method of processing natural gas to produce methanol, including the selection of natural gas under pressure, heating, gas desulphurization, catalytic steam conversion to produce converted gas, heat recovery, gas compression, methanol synthesis with unreacted gas circulation, heat recovery of the latter with further cooling in an air apparatus cooling and in the refrigerator of circulating water, the condensed methanol separation, characterized in that the source of natural gas at a pressure of 30-45 atm share and two streams in the ratio (75-85) / (25-15), the first main process stream is directed to heat up to 80 o C in the pipe space of the high-pressure recovery heat exchanger with heat of circulating gas with a temperature of 105-110 o C, and the second stream after throttling and heating in a methanol heater to a temperature of 50-60 o C is used as fuel gas.
