    摘要： The corrosion rate of a metal immersed in a fluid medium is measured by transmission of a beam of radiation normally in the visible or near infra-red portion of the spectrum, through a thin film of the metal immersed in the medium. The film of the metal is suitably supported on a radiation-transmitting substrate such as a glass plate or slide. The corrosion rate can be determined by passing a radiation beam through the metal film sample using a twin beam system to compensate for instrument factors such as the absorbance by the fluid medium, the cell windows and the film-supporting substrate. As the thickness of the film decreases, the reduction in film thickness is determined by the increase in beam intensity, using a reference beam to compensate for the instrument factors.

    摘要： A use of a foulant collector in a vessel or conduit in a paraffinic froth treatment (PFT) process. The foulant comprises asphaltenes. The foulant collectors are purposed to reduce build-up in the vessel or conduit and/or to reduce downstream foulant carry-over in the process. The surface of the foulant collectors may have an average water contact angle of less than 90 degrees. Additionally, together with such foulant collectors, a fluorocarbon polymer may be used as a surface of a vessel or conduit in the PFT process, for reducing fouling.
