Corrigendum to “Application of a New Method in Identifying the Sludge Deposits from Refineries and Gas Plants: A Case of Laboratory-Based Study”

In the article entitled “Application of a New Method in Identifying the Sludge Deposits from Refineries and Gas Plants: A Case of Laboratory-Based Study” [1], Rasha A. AlGhamdi was missing from the authors’ list. Rasha A. AlGhamdi performed the separation of the inorganic materials part (non-hydrocarbon) from the hydrocarbon part for the complex sample such as sludge deposit collected from theNG line, where the methylene chloride was insoluble. Rasha A. Al-Ghamdi also conducted the materials characterization of hydrocarbon parts using both the thermal gravimetric analysis and gas chromatography mass spectrometry techniques. Additionally, Rasha A. Al-Ghamdi interpreted the results, e.g., type of hydrocarbon (i.e., hydrocarbon type was diesel with the C10–C27) and the amount of inorganic compound, water, and hydrocarbon content (3 wt% of inorganic compound, 25wt% of water, and 72wt% of hydrocarbon content). The corrected authors’ list is shown above.
