Abstract
Цей винахід стосується вдосконаленої обробки рідких вуглеводневих сумішей, що мають тенденцію до утворення при зберіганні і/або обробці твердих органічних відкладів, особливо на основі вуглеводнів, які потім залишаються у вигляді небажаних щільних відкладів усередині трубопроводів, насосів, фільтрів, контейнерів і подібного устаткування, і вимагають значних витрат на очищення. Зокрема, ця проблема стосується транспортування, зберігання і/ або перекачування сирої нафти, що має високий вміст вуглеводнів парафінового ряду і/або відповідно обробки нафтових фракцій, що містять такі вуглеводневі сполуки. Подібні проблеми можуть також виникати при перекачуванні і обробці природного газу.
