“…Macro-and micro-crystalline waxes have different functional properties (including viscosity and melting point) due to the differences in their hydrocarbon content (linear or branched). Oliveira et al [35] investigated the influence of micro-and macro-crystalline paraffin on the properties of crude oil and found that Mic-wax can be dissolved or dispersed in solvents and display a sharp transition of gel-strength. The micro-crystalline wax usually crystallizes at a higher temperature compare to macro-components where stronger gels are formed.…”

Deposition and precipitation of paraffin wax in pipelines are major problems in the production, transfer, storage, and processing of crude oil. To prevent complete clogging, it is necessary to minimize and remove deposited wax in pipelines and tubing. Significant research has been done addressing the mechanisms of wax formation and its composition. In this review, the status of research and perspectives on the occurrence and characterization of the paraffin wax that forms in crude oil developing wells and pipelines has been critically reviewed. Several approaches for detecting paraffin wax and managing wax formation damage during oil recovery were discussed. This review also highlighted the effects of temperature and crude oil type on wax formation.

“…In general, waxy crude oils contain mainly nparaffins and small amounts of branched and cyclic paraffins. However, some crudes contain n-paraffins in small quantities relative to branched and cyclic paraffins 15 . The latter ones have a high pour point, which causes a deterioration in the rheological (mobility, fluidity, etc.)…”

Global demand for crude oil has grown significantly over the past two decades. However, conventional light crude oil production is declining, and more and more deposits of heavy and waxy oil, including high waxy ones, are being developed, creating new technological challenges at every level of the process, from production to transportation and refining. Among the various problems, the main one is wax deposition. Since the costs of maintenance, repair, and achieving the required low-temperature properties of commercial oil products are very high, solving this problem becomes critical. The paper discusses the existing problems of production, transportation, and refining of waxy crude oil and analyzes the methods of their solution.
