摘要：A process and apparatus to extract and recover heavy metals and sulfur fromcrude oil (3) or petroleum fuel products consisting of the steps of emulsifying (4) thecrude oil with an emulsifying agent (5), adding a leach solution (14, 17) to the emulsifiedcrude oil and leaching (7) the emulsified crude oil at elevated temperature and pressureto give a leached emulsified crude oil. The leach solution may be acid or alkali. A
proportion of the leach solution (16) is extracted for recovering heavy metals. There canalso be a microwave hydro-treating step (9) using hydrogen gas (10) at a temperaturebelow 220 °C to ensure there is no quality degradation in the crude feed to produce adesulfurised crude oil (20) and a hydrogen sulphide by-product and recovering sulfurfrom the hydrogen sulphide by-product.
