The current law of the market economy: "After the recession, growth begins" - is especially evident in the cost of processed petroleum hydrocarbons and natural gas used as fuel. It is the lot of economists to make assumptions about which next records the price will break. Scientists and technologists have long prepared their options, among which bioethanol (alcohol obtained in the process of processing raw materials of plant origin) occupies a leading position in terms of consumption as a fuel:
- It does not require a radical re-equipment of the internal combustion engines operating on it.
- Does not emit harmful substances during combustion in the form of vapors and hazardous particles of heavy metals.
Even today, in the absence of a deficit for classic fuel oil products and gas, bioethanol is used as an additive to gasoline and allows increasing its technical parameters and environmental component. This means that having our own production of this product is quite a promising and profitable investment.
What is the production complex
The manufacture of the final product in the form of alcohol belonging to the category of bioethanol implies the use of plant products as raw materials. According to the site https://agrotechnology.com.ua/, the varieties and types of crops used must contain a sufficient amount of sugar (glucose) for starting a natural chemical fermentation process (for example, potatoes, beets, corn or canola). It is in this way that the required concentration of alcohol components necessary for distillation is obtained. The procedure for distillation or dehydration of methanol can be carried out in several ways:
- Adsorption using molecular sieves - the role of the sieve in the evaporator column is played by a filter made of artificial zeolite, which retains molecules of a certain size. Thus, water molecules are retained on its surface, and the molecular structure of ethanol passes and condenses in the form of a finished final product.
- Membrane dehydration - a liquid heated to a vaporous state under a certain pressure through the pipeline system passes through ceramic and polymer membranes installed one after another. They hold water molecules on their surface and allow vaporous ethanol to pass through for further absorption.
In both versions, all the necessary equipment is compactly located in the body of a single column, the dimensions of which depend on the productivity (the amount of processed semi-finished product per unit of time).
