Abstract: A method for testing salt formation includes heating, by a first heater of an apparatus, an anion solution arranged in a first vessel of the apparatus to a first predetermined temperature and heating, by a second heater of the apparatus, a cation solution arranged in a second vessel of the apparatus to a second predetermined temperature. The method also includes conveying, by a fluid pump of the apparatus, a volume of the anion solution from the first vessel to the second vessel and simultaneously rotating a stirrer arranged in the second vessel to form a mixed solution. The method includes conveying the mixed solution from the second vessel of the apparatus to a sampler of the apparatus.

Abstract: A system and method for delivering volatile corrosion inhibitor (VCI) for protecting against external corrosion to the bottom, soil-side, surface of a storage tank is disclosed. The VCI delivery system can include a transport material buried underneath the tank and a carrier structure for containing the transport material. VCI can be supplied to the transport material from an external VCI storage tank and the supply regulated by a control valve. The transport material is configured to adaptively and controllably release VCI into the soil in response an external stimulus. The transport material can passively adjust the VCI release rate as a function of a stimulus including pH or soil potential. Additionally, a control system can monitor soil conditions and generate the stimulus that triggers the release of the VCI. Also disclosed are systems and methods for deploying the VCI delivery system under the tank using horizontal drilling techniques.
