dc.description.abstract |
The formation of organic acids due to secondary
reactions is an issue in industrial methanol synthesis. As such, to
avoid the formation of acidic regions in the units downstream of
the methanol synthesis loop, caustic dosing is a common practice
in the industry. Despite these precautions, some organic acids can
be left in crude methanol discharge from the methanol synthesis
loop. The objective of this study was to identify if the mode of
operations in the methanol distillation units that purifies the
crude methanol into high purity product can potentially lead to
an accumulation of trace organic acids within the main refining
column, which can lead to the formation of an acidic region
within the column. To carry out this work, the main refining
column of an industrial methanol producer was first simulated
on the industrial process simulation platform VMGSim, and then
validated against available data. This simulation was then used to
study the accumulation of organic acids ranging from formic acid
to valeric acid, where they were added to the feed stream at a
concentration of 1 ppm. The study found that propionic and
butyric acid, in particular, can accumulate significantly in the
middle of the column reaching a concentration of 40 to 80 ppm
creating an acidic environment ( PH 3.63), which can cause
corrosive damage. |
