With modern pressure-fractionating equipment, the separation of liquefied petroleum gases into propane, n-but&ne, and iso butane is a relatively simple procedure which is being conducted in many plants. The resulting butane is employed as a carbureting agent, and propane, in addition, is used in refrigerating equipment. Liquefied isobutane or propane are extracting agents for the refining of resins and gums (80,103) or oils and asphalts (3,93,122). AlcoholsThe conversion of olefins to alcohols is accomplished by absorption in sulfuric acid. The alkyl sulfuric acids which arc formed as intermediates are then hydrolyzed to alcohols. INDUSTRIAL AND ENGINEERING CHEMISTRYVol. 26, No. 8 occurs (49). Most lubricating oils contain reactive hydrocarbons which are partly removed from the oil by agitation with sulfuric acid. The sludges from such refining operations contain free acids, polymerized bodies, asphaltic materials, and oxidized substances together with various sulfonated products.

The research on the flowability of waxy oil has spanned more than a century and is still attracting much attention. How to improve the flowability of waxy oil to ensure safe and efficient pipeline transportation and storage is of great practical importance for the industry. In this work, we have systematically reviewed the research advances in improving the flowability of waxy oil. First, the crystallization properties and phase behavior of waxes are described based on their chemical structure, thermodynamic properties, and solution phase properties, with emphasis on the solventized layer properties of wax crystals. Then, the mechanisms, process, and research progress in flow improvement of waxy oil are discussed from three major aspects: process improvement, equipment improvement, and chemical treatment, with emphasis on the summary of waxy oil pour point depressants in recent years. The remaining challenges and perspectives for future research on flow improvement of waxy oil are presented.
