- Abstract
Paraffin deposition is a serious flow assurance issue faced by the Petroleum industry which can be mitigated by different techniques among which chemical treatment is the most practical solution to reduce the pour point and improve the cold flow properties of crude oil. However, the utilization of environmentally hazardous chemicals for mitigation of this severe issue also causes additional threats. Thus, motivated by such a problem, current research endeavor to synthesize and application of ecofriendly products for the mitigation of paraffin deposition. Cashew nut shell liquid (CNSL) collected from cashew nut shells was esterified with ethanol amine. The CNSL derivative (CD) was tested as a pour point depressant and cold flow improver for paraffinic crude oils. The pour point of doped crude oil was significantly reduced reaching a maximum of 120C and viscosity was tremendously dropped up to 90%. CD demonstrated remarkable paraffin inhibition efficacy of up to 56%. Photomicrographs of treated crude oil were inspected, revealing changes to the wax shape and microstructure. Thus, CNSL can be utilized as a flow improver for waxy crude oil and it has potential as a renewable chemical feedstock for the manufacturing of pour point depressants and other oilfield chemicals.
