20140260567 | METHOD OF ASSESSING ASPHALTENE INHIBITOR EFFICIENCY - Methods of assessing asphaltene inhibitor/dispersant efficiency are disclosed. Also disclosed are methods of assessing solvent/dispersant/cleaner efficacy for remediating asphaltene deposition. The methods are useful in facilitating the production, transportation, storage, and separation of crude oil and natural gas, and more particularly, for preventing the undesired deposition of asphaltene from crude oil. | 09-18-2014 |
20150355076 | FOULING PROBE FOR MEASURING FOULING IN A PROCESS FLUID - A fouling test probe includes a chamber containing a plurality of test wires secured to a replaceable test wire assembly. An actuator selectively opens and closes inlet and outlet windows to the chamber, a controller controls the actuator and independently controls an amount of electrical current to each test wire, and a voltage sensor measures the voltage across each test wire. The test probe is disposed into a process fluid, the chamber is opened allow process fluid to flow through the chamber, and the chamber is closed to capture a sample of the process fluid within the chamber. An amount of electrical power is independently controlled to the test wires while the chamber is closed, and an amount of foulant accumulation on the test wires is determined, using heat transfer measurement to determine a fouling factor. | 12-10-2015 |
