摘要：

Microwave radiation in closed vessels was applied for removal of sediments from crude oil allowing the subsequent crude oil characterization in laboratory. Heating time and microwave power were evaluated in the range of 5 to 30 s and 300 to 1400 W, respectively. Sediment content was determined using the method recommended by ASTM D 4807-05 based on a filtration step in a membrane before and after sediment removal. Water and chloride contents were determined in the oil phase obtained after sediment removal. Up to eight samples of 20 g of crude oil could be simultaneously processed. Sediment removal efficiency was better than 95%. It was possible to obtain crude oil in a suitable condition for determination of routine parameters as API gravity, density, viscosity and total acid number without interferences caused by sediments or even water and salt.
