Abstract
Currently, the processing of plant waste is a promising area of development in modern energy. There are many methods for
recycling waste, but not all of them are economically feasible and environmentally friendly. One of the most common processing
methods is fast ablative pyrolysis, designed for thermal processing of waste without access to oxygen. As a result of such processing,
carbon residue and pyrolysis gas are formed. The amount of pyrolysis gases produced is 60 % or more of the mass of processed raw
materials. In order for pyrolysis gases to become high-quality fuel, they must be subjected to a separation process that takes place in
devices called a vapor condenser. When separating pyrolysis gases, it is better not to use conventional oil and gas condensers since the
condensed pyrolysis gases have a high tar content, which causes faster wear of the device. For the installation for the production of
pyrolysis fuel, a two-stage separation system is proposed, designed to separate pyrolysis gases into fractional components: pyrolysis
distillate, non-condensable combustible gas and water. The article presents the design of a two-stage separation system. The principle
of operation of a two-stage separation system is described, and a diagram of its structure is given. A method for calculating a two-stage
separation system is presented, which makes it possible to determine the geometric parameters of scrubber and ejector type capacitors.
