“…Jiang et al (2006) found that the optimum molecular mass of EVA for pour point depression is 1.2 9 10 4 Da, but the influence of the relative molecular mass distribution is negligible. This conclusion might be appropriate for asphaltene-free oils; however, for the asphaltene oils, the situations would become more complicated (Taraneh et al 2008).…”

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.

“…Initially, the sample will be subjected to a shear rate of 1000 s -1 to erase its memory (Taraneh et al, 2008). All the samples will be subjected to a preshear for 60 seconds with a shear rate of 0.15 s -1 , for a correct homogenization of the sample (Al-Roomi et al, 2004;Li and Zhang, 2003).…”

“…The majority of crude oil and its products contain large amounts of oil wax called paraffin. Paraffin is a mixture of hydrocarbons formed from linear or normal chains, which are mainly composed of 20 to 40 carbon atoms [2]. Paraffin wax deposition causes equipment failure, upstream and downstream flow congestion, and loss of production, transportation capacity, and storage [3].…”

“…One type of bio-solvent that can be produced from biomass is bioethanol [19][20][21]. The raw materials for bioethanol can be sourced from: (1) biomass starch such as corn, cassava, and sorghum [12]; (2) sugar sources, such as cane crops, sugar cane juice, coconut sap, and gum [22,23]; and (3) source of cellulose including rice husks, bagasse, and corncobs [24,25]. In general, biomass basically consists of cellulose, hemicellulose, and lignin [19,26,27] which the availability of its raw materials is a great potential to be utilized.…”

Review of Solvents Based on Biomass for Mitigation of Wax Paraffin in Indonesian Oilfield

This paper presents a review of the expectations and challenges of using biomass in the prevention and slowing of paraffin wax deposition that takes place during the crude oil production process. The inhibition of the deposition process involves the use of solvents from biomass that are generally available around the crude oil production field. The processes used to scale down the precipitation of wax include mixing crude oil with the manufacturer's solvent composed of toluene and xylene. The goal is to assess solvents sourced from biomass that are capable to slow down the wax deposition process. Wax appearance temperature is an important characteristic to evaluate the possible wax precipitation of a given fluid. Wax precipitation can be reduced by using some chemical additives, often called the pour point depressant. This additive is expected to be produced from local biomass which can compete with solvents currently produced on the market.
