Analysis of the technogenic load on the environment during forced ventilation of tanks
Journal Title: Технологический аудит и резервы производства - Year 2018, Vol 1, Issue 3
Abstract
<p><em>The object of research </em><em>is an above-ground vertical steel tank, used as storage tank for light oil products (gasoline, diesel fuel, kerosene).</em> <em>One of the most problematic places of this operation is extremely high level of explosion and fire risk, and therefore, a significant danger to the life and health of people in the zone of influence of reservoirs. Within forced ventilation of the VST-5000 tank, 1.5 tons of petroleum products vapor enters the atmospheric air. To address this shortcoming, the application of the absorption-condensation technology of vapor recovery of oil products, the efficiency of which reaches 99 %, is proposed in this paper.</em></p><p><em>During the study, software ALOHA was used that allows to enter details about a real or potential chemical release, and then it will generate threat zone estimates for various types of hazards. The results of the study have shown that the size of the zone of acute toxic effects on the population reached 1.2 km, the fire danger zone was 80 m and the explosion zone did not exceed 13 m. Such indicators indicate a high level of environmental hazard. </em></p><p><em>The use of the ejector method of air supply during forced ventilation of tanks with the subsequent capture of petroleum fumes by means of an absorption and condensation unit ensures prevention of such a risk. The caught oil products are subject to further use, which provides additional income. Thus, the proposed method allows not only to reduce the technogenic load on the environment (ecological effect), but also has an economic effect.</em></p>
