Alternative energy suppli of food industry
(2019) Seryogin, Oleksandr
Global energy supply problems are shifting to the level of autonoms energy supply for food basinesses. In addition to environmental issues, thera are a number affactors that affect the competitiveness of food businesses. Unstable energy supply , fluctuaations inenergy prices associated with the use of traditional energy sources, impede the development of companies and corporation. Over the last 10 years, electricity prices for Bulgarian industrial enterprises have increased several times.
Energy independence problem solving by biomass technologies
(2021) Shtefan, Yevgenii; Seryogin, Oleksandr
In the first third of the 21st century, the world economy has faced significant challenges in the energy sector, and biomass as an energy resource can make a significant contribution to the production of heat, electricity and biofuels. Modern leading energy companies have experience in research, development and implementation of all bioenergy technologies (including direct combustion, co-incineration, anaerobic digestion, energy production from waste), as well as experience in bioeconomics. Organizations operating in the waste sector play a key role in the transition to a circular economy. They manage a significant part of the materials’ flows and produce resources which can be re-injected into the economy, either as materials or as energy. The sector also provides an essential environmental service for our society, both from a citizens’ point of view and from the perspective of the industrial, agriculture, and service sectors. It frees every household and organization of their waste, and it reduces related risks. The main motivation for the introduction of heat generating capacity on biomass is independence from imported energy, which ensures the energy independence of the state as an important component of its political and economic independence.
Energy-saving technologies for disposal of waste with printing design elements
(2022) Shtefan, Yevgenii; Seryogin, Oleksandr
Waste is an objective consequence of the civilization development, which creates many problems and requires decisive environmental action. But, on the other hand, waste is a resource that, in a market economy, can contribute to the overall energy balance. Municipal solid waste (MSW) (household waste and waste from other sources, such as retail, administration, education, health services, accommodation and food services, etc.). This fraction includes a wide range of products from different materials - organic, plastic, metal, paper, glass, bulky items, batteries, exhaust oils/lubricants, light bulbs, etc.). It represents around 10 % of the total waste generated by mass. More than 90% of MSW has varnish and paint coatings due to printing design. The removal of such paint elements by sorting technologies presents a significant technical challenge
Organic biomass – alternative energy source
(2013) Seryogin, Oleksandr; Osmak, Alexei
Наведено перспективу виробництва синтез-газу шляхом термічної конверсії органічної сировини. Описано принцип роботи газогенератора для спалювання рослинної біомаси. Shows the prospect of producing synthesis gas by thermal conversion of organic materials. We describe the principle of the gasifier for biomass burning.
Physic-chemical aspects of energy substitution technologies in modern production processes of printing enterprises
(2024) Shtefan, Yevgenii; Seryogin, Oleksandr
Thermodynamic models allow us to evaluate the maximum theoretical efficiency of the process and describe the equilibrium composition of the system. The process of thermochemical conversion is influenced by three macrokinetic restrictions: The restriction associated with the fact that the gasification process tends to the boundary of the formation of free non-gasified carbon. Upon reaching this boundary, an equilibrium is established between the solid and gas phases. The limitation associated with the thermal regime of the process, which, regardless of the reaction parameters determines the efficiency of the process and the composition of the resulting synthesis gas. The restriction associated with the fact that after the onset of a stationary state, additionally added heat to the system is mainly used to heat the reaction products, and not to change their composition.
Practice of ecological management of waste disposal with elements of printing design
(2022) Shtefan, Yevgenii; Seryogin, Oleksandr; Ilienko, Boris; Chornyi, Yuriy
Розглянуто проблему захоронення твердих побутових відходів з урахуванням наявності в них включень у вигляді лакофарбових покриттів поліграфічного дизайну. Показано, що їх утилізація, враховуючи, що понад 90 % твердих побутових відходів мають такі включення, потребує обґрунтованих технологічних рішень. Показано, що основною проблемою є утилізація змішаних відходів, до яких належить уся пластикова упаковка з побутових відходів, а також жорсткі та гнучкі вироби з полімерів різних типів та кольорів, які за-звичай створюються з елементами друкованого дизайну. Пропонується використовувати високотемпературні методи утилізації на основі процесів піролізу та газифікації. Такі методи доцільно розглядати в поєднанні з технологіями отримання альтернативних енергоносіїв та отримання на їх основі різних видів речовин та енергії, наприклад, механічної, теплової та електричної. Наведено опис процесів газифікації низько сортового твердого палива за методом термодинамічного моделювання. Показано, що економічна ефективність утилізації відходів суттєво підвищується при поєднанні процесів піролізу та газифікації, коли процеси утилізації відходів піролізної установки та газогенератора об’єднано в один технологічний процес, що дасть можливість довести утилізацію відходів майже до 100 %.
Studies of physical and technical characteristics of biowaste as components of gasification
(2014) Osmak, Alexei; Seryogin, Oleksandr
Proved promising use of plant biomass as a fuel due to the widespread introduction of bioenergy technologies. Justified the use of biomass for heat and electricity. The basic reasons for the use of organic materials as a source of renewable energy. The examples of industrial use of energy from biomass in the EU. Investigated the variation of the calorific value of the product gas from the humidity of the incoming raw materials. By experiment investigated the suitability of various types of plant biomass (sunflower husks, hulls of buckwheat and oats) to further thermochemical conversion for alternative fuel.The results of the technical analysis (moisture, ash, calorific value) of a number of analytical samples of agricultural waste.Studied the elemental composition of certain types of plant material, which suggests that these agricultural residues are highly reactive fuel with a high yield of volatiles.

(2021) Seryogin, Oleksandr; Vasylenko, Oleksandr; Riedel, Frank J.; Aigner, Helmut
A concept has been developed for processing of biologically active sludge from municipal wastewater treatment plants in combination with the organic fraction of municipal solid waste using the BioTech Process. The complex, which makes it possible to implement the proposed concept, does not require additional land plots, and classified secondary raw materials, biogas and high-quality biofertilizers suitable for use in the agricultural industry are the products of its activity. The proposed concept will allow solving several problems at once due to the construction of a waste recycling plant on the territory of the filtration zone of the existing water treatment facilities. The new processing plant will be used not only for processing and sorting of solid waste, but also for treating sludge from wastewater treatment plants, together with organic waste obtained from solid waste in the BioTech Process to obtain biogas and biofertilizers, the so-called compost. The new recycling plant will be environmentally friendly and, among other benefits, will be able to process of municipal solid waste with preliminary sorting and separation of recyclable materials.
