ON-LINE, THERMO-CHEMICAL PROCESS FOR THE DEWAXING OF OIL EXPORT PIPELINES

摘要

An on-line, thermo-chemical process for the dewaxing of oil export pipelines with the aid of a Nitrogen Generating System is described, wherein the treating fluid to be employed as dewaxing fluid comprises: a) a solution of nitrogen salts activated by emulsified acetic acid and designed to yield nitrogen and heat, and b) a solvent, which is the pretroleum oil being produced. The dewaxing treatment is effected at the same time as the pretroleum oil is produced, this leading to great savings in costs and energy.
