Abstract:

To address the issue of pipeline blockage caused by the formation of waxy deposits inside pipelines, hindering the flow of petroleum in the Shengli oilfield, eight new-style polyacrylic acid pour point depressants (PPD) for Shengli crude oil were prepared by maleic anhydride and ene monomers with different polar and aromatic pendant chains. The synthesized Pour Point Depressants were characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), and polarizing optical microscopy (POM). The results were promising and demon

Abstract:

The effect of pour point depressants on crude oil properties is critical for ensuring smooth operations and efficient transportation. This paper presents experimentally determined characteristics of two high waxy crude oils from the Western region of Ukraine: Dolyna and Boryslav. The study demonstrates that selecting optimal additives can significantly enhance low-temperature properties, reducing the pour point and improving flowability. The selection process for depressant additives is justified, and their comparative characteristics are discussed. Considering efficiency, cost, and availabili

Abstract:

The pour point depression of a Nigeria waxy crude oil was investigated using modified African pear seed oil. Waxy Crude oil sample collected from a marginal field in Delta state. African pear seeds sourced from Choba Port Harcourt were extracted from their oil content and the oil was modified using ethylene glycol and diethanolamine via the esterification and aminolysis reaction respectively. These modified products were applied as pour point depressants. The waxy crude oil was dosed with the modified African pear seed oil of concentrations 0.1ml, 0.2ml and 0.3 ml. The result showed a reductio

Abstract:

The interaction between n-alkanes and pour point depressants with different structures was investigated. Using n-hexadecane as the representative component of crude oil n-alkanes, molecular simulation was employed to study the interaction between polyacrylate pour point depressants with different side chain length and n-hexadecane, and the interaction between polyacrylate pour point depressants with different polar building blocks and n-hexadecane. It was shown that during wax precipitation process, the mixed energy is low when the side chain length of acrylate is compatible with n-hexadecane.

Abstract:

Transmisi crude oil merupakan proses penyaluran crude oil dari satu plan ke plan yang lain. Permasalahan yang sering terjadi pada proses transmisi crude oil adalah pembekuan atau kristalilasi parafin apabila suhu di lingkungan menyentuh Pour Point Temperature. Biasanya hal tersebut dapat diatasi dengan penginjeksian Pour Point Depressant ke dalam crude oil. Namun, penggunaan Pour Point Depressant masih belum efektif apabila digunakan secara terus menurus. Hal ini karena Pour Point Depressant dapat mempengaruhi kualitas dari crude oil, meningkatkan risiko lingkungan dan apabila proses trasmisi

Abstract:

Kinds of pour point depressants were prepared from common monomers, octadecyl acrylate, maleic anhydride, styrene, acrylamide and vinyl acetate. Because the monomers have various functional groups, the performance of the polymers that were prepared from different monomers showed different. The performance of the pour point depressants on solubility in diesel and the drop of pour point on Daqing crude oil was studied. The results showed that styrene and vinyl acetate could increase the solubility of the pour point depressants; maleic anhydride and acrylamide could improve the drop of crude oil

Abstract:

A new type of nano-material based hybrid pour-point depressant with significant efficiency has been developed and successfully used in industrial application. For Daqing crude oil, a typical high waxy Chinese crude, with 80–100g/t new pour-point depressant and 58–65°C thermal treatment temperature, the wax appearance temperature of the Daqing crude oil can be decreased by 3–4°C. The viscosity/pour-point reduction, shearing resistance, and fluidity at low temperature of the modified crude with new type of pour-point depressant is much better than the effect of using traditional ethylene-vinyl a

Abstract This research work focuses on the evaluation of novel and eco-friendly additives as pour point depressants for crude oils to improve the flow properties. Neem oil, rogan kahu, rogan khashkhash, kalonji oil and mahua oil were tested for the pour point studies on a model oil containing two different types of waxes. The study reflected that rogan khaskhas beneficiated crude oil showed highest depression in pour point i.e. up to 6 °C and 10 °C in Type 2 and Type 3 wax embedded base oils respectively, indicating the best additive amongst the five additives tested.
