  • Method for fast estimation of distillation residues and coke characteristics
    Patent number: 9638682
    Abstract: The present invention relates to a method of estimating, for a petroleum feedstock, values representative of the sulfur and carbon distributions in atmospheric and vacuum distillation residues, and a value representative of the sulfur content in coke. According to the method, the following stages are carried out: from a feedstock sample, measuring at least the Rock-Eval parameters S2b, SulfS2b, RC, Sulfoxy using a Rock-Eval device comprising a sulfur measurement module, deducing from the measurements of these Rock-Eval parameters the values of the sulfur and carbon distributions (SPHF, SCOKE, CPHF, CCOKE) in the distillation residues, and a sulfur content in relation to the carbon content in the coke.

  • METHOD AND SYSTEM FOR PREPARING A PIPELINEABLE HYDROCARBON MIXTURE
    Publication number: 20160108324
    Abstract: The present invention provides a method for preparing a pipelineable hydrocarbon mixture from a crude heavy hydrocarbon mixture comprising: —visbreaking said crude heavy hydrocarbon mixture at a temperature of 350 to 440° C. and a pressure of 20 to 150 bar for 0.5 to 15 minutes to produce a visbroken hydrocarbon mixture; and —mixing said visbroken hydrocarbon mixture with a diluent to produce said pipelineable hydrocarbon mixture.
