The reaction product from the reaction section of the mole fraction consisting of the following: H2 %, CO2 %, H2O %, CH4 %, C2H6 %, C2H4 %, C3H6 %, C3H8 %, C4H8 %, C5H12 %, Due to be aggregated ethylene and propylene polymerization grade relatively harsh conditions, So we must remove the mixture of CO2 and H2O. This section is designed primarily to remove CO2 and H2O, This section is designed primarily to remove CO2 and H2O, Through access to relevant documents and materials, design year of processing 800000 tons of crude methanol to olefins pretreatment process flow a
