1. What is the main task of the methanol synthesis unit? Answer: The methanol synthesis unit converts the feed gas containing H2, CO, and CO2 into crude methanol under certain pressure (5.9 Mpa), temperature (210–290°C), and in the presence of a catalyst (Cu). It then carries out the separation of methanol, and utilizes the heat generated by this reaction to produce steam, which is fed into the steam network.

Answer: The methanol synthesis unit converts the feed gas containing H2, CO, and CO2 into crude methanol under certain pressure (5.9 Mpa), temperature (210–290°C), and in the presence of a catalyst (Cu). It then carries out the separation of methanol, and utilizes the heat generated by this reaction to produce steam, which is fed into the steam network.
Under high temperature, high pressure, and in the presence of a catalyst, a mixture of H2, CO, and CO2 reacts in a synthesis tower to produce methanol. The gas resulting from this reaction is cooled to separate out the methanol; the unreacted gas along with fresh gas is pressurized again and sent back to the synthesis tower for further reaction. The heat generated during methanol synthesis is used to produce steam at 2.5 Mpa as a by-product.
Under high temperature (210–290°C), high pressure (5.9 MPa), and in the presence of a catalyst (Cu), a mixture of H2, CO, and CO2 reacts in a synthesis tower to produce crude methanol. The gas after the reaction is cooled and condensed to separate out methanol; the unreacted gas along with fresh gas is pressurized again and sent back to the synthesis tower for further reaction. The heat generated during methanol synthesis is used to produce steam at 2.5 MPa, which is then fed into the steam network.

The methanol synthesis section converts the feed gas containing H2, CO, and CO2 into crude methanol under specific conditions of pressure (5.9 Mpa), temperature (210–290°C), and in the presence of a catalyst (Cu). It also carries out the separation of methanol, generates steam as a by-product of the reaction heat, and incorporates this steam into the steam distribution network.

Under high temperature, high pressure, and in the presence of a catalyst, a mixture of H2, CO, and CO2 reacts in a synthesis tower to produce methanol. The gas resulting from this reaction is cooled and condensed to separate the unreacted gases from methanol; the fresh gas used as a supplement is then pressurized and sent back to the synthesis tower for further reaction. The heat generated during methanol synthesis is utilized to produce steam at 2.5 Mpa.
