Medium pressure method for the synthesis of ammonia

Medium pressure method

Operating pressure is 20 ~ 60MPa, temperature 450 ~ 550 degrees Celsius, the advantages and disadvantages between the high pressure and low pressure method, this method is more mature, more economical and more economical. Because the determination of the synthesis pressure, nothing more than from the equipment investment and compression power consumption in these two areas to consider. From the perspective of power consumption, the power consumption of the composite system occupies the largest proportion of the total power consumption of the whole plant. Power consumption is not only depending on the pressure, but also to look at other process indicators and the layout of the process. Overall, in the range of 15 ~ 30Pa, the power consumption of the difference is not big, so a lot of the world by this method.
