Scientists from the Tomsk Polytechnic University (TPU) have developed a method to reduce energy consumption in refineries – it’s now possible to save more than half of the fuel at the explored site.
The university researchers are convinced that such results can be achieved in almost any industrial production.
The article was published in the Energy Conversion and Management academic journal.
The experts from TPU proposed a method to reduce energy consumption in hydrocracking – processing high-boiling oil fractions to produce fuel at refineries. As a result, the consumption of fuel gas and fuel oil decreased by 54 percent and electricity by 20 percent in the enterprise where the research was carried out.
The use of heat exchangers in a certain sequence has increased energy efficiency.
The method can be used both for the reconstruction of existing plants in the manufacturing sector and for the design of new, more energy-efficient, and environmental-friendly plants, the researchers reported.
Such improvements would reduce the costs of the final production as well as the impact on the environment. Fuel savings at the refinery, where the experiment took place, helped to reduce CO2 emissions by 19,000 tonnes per year. The less fuel the factory burns, the less gas it emits into the atmosphere. According to the experts, such results can be achieved in almost any industrial enterprise, including abroad.
To create an optimal flow structure, scientists used pinch technology, principles of continuous integration, graph theory, and the fundamentals of heat-mass exchange.
The team of scientists continues to work on decarbonisation and reduction of harmful emissions of industrial and territorial complexes by developing new advanced methods for integration of industrial enterprises, the public sector, and the environment.
