FIELD: process engineering.
SUBSTANCE: production of methanol by vapour conversion comprises making of synthesis gas by vapour conversion with a definite excess hydrogen and mixing it with partially oxidised synthesis gas produced in partial oxidation section and having low hydrogen content to obtain gaseous agent in synthesis circuit with balanced stoichiometric factor. Method of reconstruction of usual methanol plants comprises introduction of partial oxidation section in parallel with existing conversion section.
EFFECT: increased output.
