The petroleum industry has addressed wax problems since its inception. Every year, considerable resources are expended on wax removal, which accordingly cause significant economic loss. As one of the materials in chemical treatments, polymeric compounds referred to as ''wax-crystal modifier'', is being widely used to improve flow properties and/or combat wax deposition for waxy crude oils. This article reviews the recent achievements with regard to the flow improvement and wax inhibition of waxy oils using traditional polymeric wax crystal modifiers, such as ethylene-vinyl acetate (EVA), poly(ethylene-butene) (PEB), and polyethylenepoly(ethylene-propylene) (PE-PEP), as well as the development of novel polymers for potential use in the near future. The goal of this review is to assist people understand the advances in this topic.

“…Generally, a cold flow improver contains an oil-soluble long-chain alkyl group and a polar structure moiety in the molecular structure. The long-chain alkyl group can insert into the wax crystal in the fuels, and the polar moiety exists on the surface of the wax crystal, thereby inhibiting the crystal lattice formation and reducing the waxes crystal size [16]. The effect of PHs concentration on the pour point of 2# crude oil was screened in the following work, and the results were summarized in Figure 1.…”

“…Visual observations suggest that paraffin crystals are larger size and more numerous in the crude heavy oil (a) than after being processed (b), as shown in Figure 2. This may suggest that some of the longer paraffinic chains were also decomposed in the aquathermolysis reaction [16].…”

In this work, poly-hydrazide (PH) is designed and prepared from vegetable oil, hydrazine hydrate and dichloroethane. Nitrogen atoms are fixed in the main chain of the polymers to modify the polarity. The effectiveness of the PHs on four crude oil was tested as pour point depressants as well as paraffin inhibiters. The results showed that the highest pour point reduction depression was achieved as 10.6℃. The paraffin crystal morphology studies were conducted on simulated crude oil to elucidate the mechanism of pour point reduction.

KEYWORDSCanola oil; flow improver; paraffin inhibition; polyamine amide; waxy crude oil ABSTRACT Several techniques are employed to mitigate the problems associated with the crystallization of paraffin during the production and/or transportation of waxy crude oil. One of these techniques is the addition of chemicals that depress the pour point of the oil and inhibit the formation of paraffin crystals. In this work, the chemicals, polyamine amide (PAA), are prepared by aminolysis and polycondensation from canola oil and polyamine as substrates. Nitrogen atoms are fixed in the main chain of the polymers to modify the polarity. The effectiveness of the PAAs on four crude oil was tested as pour point depressants as well as paraffin inhibiters. The highest pour point reduction depression was achieved as 12.6°C. Differential scanning calorimetry and paraffin crystal morphology studies were conducted on simulated crude oil to elucidate the mechanism of pour point reduction.
