Modern chemical-engineering industries should be characterized by
high efficiency and productivity. This can be achieved by the production
processes optimization, for example, by optimal control of the process.
The methanol production refers to the main productions of the chem-
ical industry. It is a heavy tonnage, nonstop production with the complicat-
ed technological scheme. The technology is characterized by the high tem-

peratures, pressure and multi relations of the processes parameters. Search-
ing effective parameters of the influence on the methanol synthesis process
and ensuring its stable operation in the optimal mode is a very important
task.
The aim of this work is the optimization of the process of methanol
air refrigeration and condensation at the synthesis stage in the methanol
production.
To achieve this goal it is necessary to solve the following technical
problems:
- analysis of refrigeration and condensation unit of methanol as a
control object;
- mathematical simulation of the air refrigeration process of the
methanol synthesis stage;
- construction of the refrigeration unit control system.
The object of the investigation is the refrigeration and condensation
stage of the methanol production synthesis. The subject of the investigation
is the refrigeration unit control system.
The investigation  methods.
A mathematical model has been developed by using computer simu-
lation method based on the heat balances of the air refrigerators. The inves-
tigation of the control system operation has been carried out by a method of
the simulation modelling on the computer with the use of SCADA – Trace
Mode VI system.
