Abstract
The invention relates to a process for preparing methanol, in which a first reactant stream having a first reactant in the form of hydrogen and a second reactant stream having a second reactant in the form of a carbon oxide-containing gas mixture are provided; the first reactant and the second reactant are fed into a synthesis reactor arrangement; and the methanol synthesis is conducted in the synthesis reactor arrangement to form a product stream having methanol. Forecasts are created as to rates of change in inflow rate of the first and/or second reactant in order to compensate for fluctuations.
Claims14
A process for producing methanol, comprising:
- a) a first reactant stream comprising a first reactant in the form of hydrogen and a second reactant stream comprising a second reactant in the form of a carbon oxide-containing gas are provided;
- b) the first reactant and the second reactant are fed into a synthesis reactor arrangement;
- and
- c) the methanol synthesis is conducted in the synthesis reactor arrangement to form a product stream comprising methanol;
- wherein the process further comprises:
- providing at least one first buffer for intermediate storage of at least one of the reactants upstream of the synthesis reactor arrangement;
- determining the inflow rate of the at least one reactant into the synthesis reactor arrangement;
- and the
- creating of a forecast with regard to a rate of change in the inflow rate on the basis of influencing variables on which the inflow rate of the at least one reactant is dependent;
- wherein
- when the forecast indicates a positive rate of change having a magnitude that exceeds a predefined first threshold value, at least a portion of the stream of the at least one reactant is diverted into the first buffer;
- and/or
- when the forecast indicates a negative rate of change having a magnitude that exceeds a predefined second threshold value, the at least one reactant is fed from the first buffer into the synthesis reactor arrangement,
- thereby adjusting the rate of change to a predefined value or predefined range.
