  • IJERPH Free Full-Text Petroleum Coke in the Urban

    Petroleum coke or petcoke is a granular coal-like industrial by-product that is separated during the refinement of heavy crude oil. Recently the processing of material from Canadian oil sands in U.S. refineries has led to the appearance of large petcoke piles adjacent to urban communities in Detroit and Chicago. The purpose of this literature review is to assess what is known about the

  • GETTING THE FACTS ON OIL MIST LUBRICATION By Don

     · Oil mist can be referred to as the ultimate oil filter. The dry mist or small particles of oil The particle size distribution of the oil mist is an important characteristic for successful lubrication. A large volume of very small mist particles (< 1.5 microns) can lead to inadequate lubrication as particles of this size will not coalesce to allow wetting. Conversely a large volume of large mist particles (> 3 microns) will fall out of suspension prior to reaching the application points. Careful selection of the correct oil coupled with the design advantages of the vortex mist head can assure the mist
