Deza implemented the system of advanced production control

On May 19, 2015 the Honeywell company announced an implementation project of a system of advanced production control in Deza company.

Project Tasks

Production of phthalic anhydride at the Deza plant provides seven basic processes and two auxiliary. For increase in production efficiency the system of the advanced management (AM) was faced by a problem of maximizing development of FA-raw at necessary restrictions:

• concentration of reagents in the reactor of oxidation is lower than the set extreme value;

• concentration of reagents in a zone of preparation of raw materials below explosive level;

• capacity of the air compressor is lower than the set upper operational limit;

• catalyst temperature in the oxidation reactor in safe borders;

• output influences of the UU system in the set limits.

Building of ABK of the Deza plant, 2013

Project Progress

The UU system managing the air compressor, section of preparation of raw materials and the reactor of oxidation is created on the basis of the program and algorithmic Honeywell Profit Controller complex.

The Profit Toolkit software application which is controlling temperature in the reactor of oxidation and regularly transferring the updated data to multiple parameter controllers of a system is used. The database of real time of Honeywell Uniformance PHD creates reports and trends of keyword parameters, providing information for the effective analysis of TP.

Software of performance monitoring of UU provides useful statistical data about system operation, including duration of its unceasing work, standard deviations of controlled variables, information on exits of variables to restrictions and many other things.

Project Results

The project paid off less than for half a year. The system utilization coefficient from the moment of its commissioning exceeded 99%.
