Resource Recovery from Crude Oil Sludge Using Solvent Extraction and Delayed Cooking Method (Published)

The main objective of this work is to make an economically useful recovery from waste. Crude oil sludge is gotten from the bottom of crude oil storage tank. 100mI (109.2g) of crude oil sludge when treated with 50mI, 100mI, 200mi……400 ml of solvent heptane resulted in the formation of three different layers. The first layer contains the solvent and some extracted crude oil in the oil phase. This is distilled to get different hydrocarbon fractions. The second layer is asphaltic residue which when furnace treated and activated or washed and neutralized with inclusion of additives yields activated coke used as adsorbent and newsprint paste respectively. The third layer is the mud or clay which could be furnace treated to produce activated clay.Results show that petroleum coke is best activated at 800°C and the optimal condition for bleaching red palm oil by the adsorbent is at 130•C.
