    Project goal:

    The current recycling technologies derived from the processes used in the crude oil processing and adapted to the waste hydrocarbons towards valuable semi-manufactured goods and products are known for their investment intensity. To build economically justified processing unit, a considerable investment capital and enough developed market for waste is required. This is another reason for the low percentage of recycling today.

    Scientific and technical workplaces around the world are on search of simpler and cheaper recycling methods for waste plastics and waste petroleum oils that might be widely implemented in practice.

    The process BLOWDEC (BLOWing DEComposition) represents a new original method based on the Slovak  patent No. 279,397.

    The main purpose of the goal is the destruction of additives and their residues through a mechanical and thermal decomposition while avoiding the coke formation at the same time. The technology is partially verified at the recycling of waste with a high content of petroleum portions and waste petroleum oils, in particular.

    The main principles of the assessment process is the waste oils processing in a hot blowing bed made from solid particles e.g. in hot sand or similar in the special equipment, a reactor that is the basic part of the whole process BLOWDEC. In course of waste oils processing, also a hydrocarbons cracking will run along with the additives destruction and separation of liquid parts to generate an economically interesting product.
