Russian oil separation plants will reduce energy losses

In petrochemical production, the method of rectification is used, which is a method of obtaining substances from

It looks like several columns: inside them are components with a high boiling point, which remain in a liquid state, and components with a low boiling point turn into steamThe main difficulty of this technology is to select the optimal order of separation of the mixture and the mode of operation of each column.

About 6% of all the energy of the oil produced is spent on this process, it is notedHowever, a method that would optimally select parathemms during rectification has not been found.Therefore, the researchers decided to offer their own unique algorithm that will help save on production. 

There are many options for separating multi-component mixtures in a rectification column cascade, and the number is rapidly increasing: for two components, the option isWhen designing multi-column rectification systems, it is important to find a simple feature for selecting a separation scheme that will provideWe were the first to do this, substantiating the method not by enumerating options, but by applying the methods of optimization thermodynamics.

The invented method will help production to calculate energy consumption more efficiently and reduce the amount of computation when designing new rectification systems and renovating old ones.

In addition, based on methods of optimizationthermodynamics specialists of YaGTU also solved the problem of choosing the maximum capacity of the column and the optimal point of input of raw materials, the coordination of loads in the column system and a number of others.
