A method for producing methanol comprises the steps of passing a feed stream of methanol synthesis pas through a main methanol reactor containing a methanol synthesis catalyst, to form a mixed gas containing methanol, cooling the mixed gas containing methanol, separating methanol from the mixed pas and heating the mixed gas. The stream of heated mixed gas is passed through an additional methanol reactor containing a methanol synthesis catalyst, and the effluent from the additional methanol reactor is mixed with the feed stream of methanol synthesis gas and passed through the main methanol reactor.

Method for producing methanol in a reactor with bypass

A process for the production of methanol from synthesis gas via an equilibrium reaction is conducted in a methanol pre-converter within a certain operational window, said operational window being defined by the area below an approximately linear curve of the partial pressure of carbon monoxide vs. the boiling water temperature for water temperatures between 210 and 270&#xb0; C. Methanol of different product grades may be obtained by operating in specific areas of the operational window.

Process and a plant for the production of methanol

A method and an apparatus for protection of a combustion unit of a chemical process against over firing, the burner(s) of the combustion unit are limited by a fuel and duty limiter which limits the duty based on process feeds, combustion gas and fuel flows.

Over firing protection of combustion unit

The invention relates to a catalytic reactor suited for exothermal reactions with a radial process fluid flow and process fluid flow guides which ensures an extended fluid flow path and higher flow velocity and thereby enhanced cooling of the catalyst bed in the reactor.
