20140134743 | METHOD FOR IDENTIFYING LAYERS PROVIDING CORROSION PROTECTION IN CRUDE OIL FRACTIONS - A method for determining and identifying corrosion protective layers that provide corrosion protection against crude oils and crude oil fractions is disclosed. The method identifies naturally occurring constituents in crude oils that indirectly provide corrosion protection. A method assessing the potential of these constituents is also disclosed. The method includes exposing metal coupons with the crude oil or crude fraction of interest at the expected operating temperature of concern. The corrosion potential assessment further analyzes the exposed coupons with transmission electron microscopy and an additional high temperature exposure that challenges the tenacity of the protection offered by the corrosion protective layer. | 05-15-2014 |
20140212978 | SYSTEMS AND METHODS TO MONITOR OPERATING PROCESSES - Example methods, systems, and computer readable media are provided for monitoring operating processes. An example method includes monitoring an equipment parameter associated with an asset in an operating process unit and monitoring a process parameter associated with the asset. The example method includes determining an asset health corresponding to the asset. The asset health is determined based on a potential state of corrosion associated with the asset by comparing a corrosivity index to a corrosion threshold. The corrosivity index is a function of at least one of current values or changes in the monitored equipment parameter or the monitored process parameter over time. | 07-31-2014 |

20150017729 | METHOD FOR EVALUATION TESTING OF MATERIAL FOR INTERNAL COMBUSTION ENGINE - An oxide film is formed on the surface of a sample made from a metal material by holding the above-described sample at a temperature of 800° C. or higher and 1,100° C. or lower in an oxygen-containing atmosphere, and the sample provided with the oxide film is immersed in a corrosive solution containing an acid and NaCl for a predetermined time. After immersion, the corrosion state (degree of denseness of oxide film, cracking state, and the like) of the sample is evaluated. The corrosion resistance of the sample can be evaluated appropriately and conveniently in a short period of time by causing accelerated corrosion in an environment simulating the actual environment of an internal combustion engine. | 01-15-2015 |
20160041085 | CORROSION MONITORING APPARATUS AND METHODS - A method for passively monitoring corrosive factors in an environment includes locating an apparatus in an environment. The apparatus includes at least one corrosion classification coupon and a temperature and humidity logging device. The apparatus is maintained in the environment for a period of time and then removed from the environment. The at least one corrosion classification coupon and the temperature and humidity logging device are analyzed to determine whether one or more of corrosive gases, temperature changes or humidity changes were present in the environment during the period of time. The temperature and humidity logging device may be an electronic temperature and humidity logging device. The analysis may be performed by an off-site vendor. | 02-11-2016 |
