Pour Point Depressant(PPD) and Flow Improver Additives (FIA) of Crude Oil and Its Study Method Progress

摘要

The situation of low temperature crude oil pipeline carrying is universal. The rapid developing of pipe line supposes higher asking on new carrying technology. The problem of long distance carrying at normal temperature of high waxy crude oil is impel to resolve and its potential social economic profit is obvious. As the pipeline is designed at high production period of field so there must have low carrying situation at beginning and ending time. At the situation the high waxy crude oil and high pour point crude oil will face on great resistance and blockage problem. Further more the pipeline has to make great energy expense on high temperature carrying. So take new carrying technology to realize atmosphere temperature carrying is crucial of resolving low temperature carrying. The method of adding chemical pour point depressant(PPD)/flow improver additives (FIA) into crude oil directly was widely used at present. The progress of the additives and its study methods was summarized in the paper and supply some reference for the technology of PPD/FIA.
