Abrégé
(EN)

The present invention relates to a process for separating oil from oil sludges. Said process comprises the following steps: the oil sludge is introduced into the cracking furnace whose internal press is kept at a level of 3 kilograms, wherein the sludge is heated to a temperature between 400 to 700 °C to crack the oil contained in the sludge to a gas state; the oil gas is cooled in a condenser to produce gas and light crude oil which are introduced to gas tank and crude oil tank separately. As an alternative, plastic garbage can be introduced into the cracking furnace together with the oil sludge to crack the plastic garbage into light crude oil and as a result, the oil recover rate is increased.

본 발명은 원유(crude oil)로부터 오일 슬러지를 분리하는 방법이다. 먼저, 원유를 함유하는 오일 슬러지를 분해로(cracking furnace)에 넣어 400-700도로 가열하고, 분해로 내부의 압력 값을 3 kg으로 유지하여 오일 슬러지에 의해 함유된 원유를 가스 상태로 분해시킨다. 다음, 제1 단계에서의 오일 가스를 냉각시키고 냉각된 후의 오일 가스는 가스와 경질유를 형성하도록 냉각한다. 다음 화학적 중간 물질 또는 증류되어 가스 오일, 디젤 오일 또는 연료 오일로서의 사용을 위해 제2 단계의 가스를 가스 취급기로 안내하고 경질유를 원유 취급기로 안내한다. 또한, 경질유의 생산을 증가시키기 위하여, 플라스틱 정크는 간접 가열 분해로의 연료로서 오일 슬러지를 고온으로 분해시키는 분해로 속으로 투입될 수 있다.
