The APC is the top level of the automated technological process control system and makes it possible to automate the operation of the unit in all modes, such as cold start and warm start, regular operation, scheduled and emergency shutdown, as well as in case of off-nominal and emergency situations.
With the sufficient level of unit automation, the APC can operate in an autonomous mode, while the operator’s participation is reduced to setting the task and monitoring key parameters.

- improving economic performance by reducing resources consumption, in particular, electricity and steam;
- decreasing the probability of the personnel’s errors while running the technological unit;
- decreasing the probability of emergency situations;
- increasing the integrated production safety;
- increasing both the system stability and technology performance

• Our highly skilled engineers-technologists are really experienced in working out solutions for various complex issues associated with operating technological units. The T-Soft specialists have examined, made simulations of, worked out emergency procedures and solved complex technological problems associated with operating technological units of various oil refinery and chemical enterprises.
• T-Soft has developed and implemented OTS's  for most technological units used by the oil refining and chemical industries. While developing the OTS's, the T-Soft specialists studied the operation peculiarities of a large number of technological units, which is extremely important for the high-quality implementation of APC. OTS's are also used to study, debug and test solutions. It should be noted that OTS's make it impossible to test the operation of the APC in case a whole range of off-nominal and emergency situations occur.
• T-Soft has developed and tested approaches that allow determining the major and minor factors and parameters that might affect the safety and security of the unit operation, as well as the production quality and performance.
• The T-Soft specialists have extensive experience while working with DCS by leading manufacturers, which is important for a reasonable combination of the capabilities of the standard and implemented control systems for the technological facility.
• T-Soft uses software of its own design that allows taking into account any Customer’s requirements regarding the functionality of the modules.

The software by T-Soft provides for the interconnection of complex intelligent control systems included in the complex of advanced intelligent management that consists of Alarms ranking system, Module for forecasting dangerous states, System of automated procedures implementation, Operator’s Assistance System; Advanced process control (APC) system.

Using all the systems enables one to ensure the safest and most efficient control of the technological process.
