Reduction of Costs in the Oil Refining Industry
Cost reduction is a key task for managing enterprises involved in oil refining. It is extremely important for such enterprises to decrease the cost of processing.
Use of Frequency Converters
To achieve this goal, it is necessary to implement frequency converters. For many years, NPFS KRUG has accumulated vast experience in their application. The main achievements have been obtained through the integration of frequency converters in the configuration of automated systems for managing technological processes.

Application of Frequency Converters
Below is a list of frequency converters used for control:
- Air cooler
- Fuel oil extraction pump
- Pump for supplying diesel circulation irrigation
Problems without Frequency Converters
A specialized system provides quality management of the operation of frequency converters due to standard current signals. At the same time, the technological process requires the use of an air cooler. Failure to use frequency converters can lead to the following difficulties:
- Temperature fluctuations after the use of air coolers;
- Change in pressure in columns, which depends on the time of day and temperature changes;
- The need for manual readjustment of flows in winter.
Positive Impact of Frequency Converters
The use of frequency converters has a very positive impact on the management of air cooling chambers. By regulating the operating frequency of the fans, the negative impact of temperature fluctuations on the functioning of cooling systems is eliminated.
- In the summer, electricity consumption reaches its peak during the day;
- At night, electricity consumption is reduced by 15%;
- In winter, the reduction in consumption can reach 15-25%.
Control Schemes for Frequency Converters
Two types of control schemes for frequency converters have been used for the operation of pumping installations.
