Abstract

The oil spill is an event of significant environmental and social risks and therefore requires prompt action in an emergency. The choice of measures to neutralize the spill occurs in a stressful state of emergency, at the same timeneed to ensure the effectiveness of the developed measures, as there is always a risk that non-compliance with measures can only worsen the situation. Usually in such conditions are based on previous experience, which is now known to prove the effectiveness of the use of sorption technologies, which are used as oil sorbents – super hydrophobic and super lyophilic materials. Carbon-based absorbents in the form of expanded / expanded / exfoliated graphite are considered to be one of the best candidates for this role. This decision is due to its significant, compared to other absorbents capacity for oil and petroleum products and relatively low cost, which makes it possible to use in spill areas of tens and hundreds of square kilometers. Accordingly, the development of an affordable mobile system for the industrial production of this absorbent capable of synthesizing it directly at the accident site is an urgent task. We have created a compact system that is able to stably synthesize exfoliated graphite by thermal shock. This system together with the power generator is placed directly in the minibus and the production of exfoliated graphite can be very quickly deployed directly at the site of an emergency oil spill or petroleum products. The need for system mobility is due to the wide geographical coverage and terminals, as well as oil storage facilities. That is, it is almost all regions of Ukraine and the world, which once again confirms the need for mobile generation of this absorbent with significant selectivity, especially for heavy brands of oil and petroleum products.

Key words: absorbent, graphite, exfoliated graphite, oxidized graphite, oil, petroleum products
