  • Apparatus and method for recovering diesel-quality fuel from produced crude oil
    Patent number: 5116485
    Abstract: An apparatus and process for recovering a diesel-quality fuel from produced crude oil is described. The diesel-quality fuel is produced by flashing the crude feedstock at high temperatures and recovering the diesel quality fuel as a liquid from a refluxing exchanger. Process efficiency is enhanced by heat integration. The process is particularly applicable to remote locations, both onshore and offshore, where conventional fuel supplies are inadequate or not available.
