摘要： The present invention relates to Delayed Coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilizes a pre-cracking reactor for mild thermal cracking of the feedstock and intermediate multistage separation system before being subjected to higher severity thermal cracking in delayed coking process, resulting in reduction in overall coke yield.

摘要： The present invention relates to resid processing, particularly related to conversion of resid material with maximum recovery of lighter hydrocarbons. The invented process utilizes a novel scheme for integration of solvent de-asphalting and delayed coking processes to maximize the residue conversion to valuable products, with cleaner quality of middle distillates and fuel oil products, in comparison with other integrated solvent de-asphalting and delayed coking schemes. This process also has an additional flexibility to vary the recycle quantity, without impacting fractionator operation of the delayed coking section, which further enhances the product recovery and achieves maximum conversion of the resid feedstock, with minimum impact on liquid product properties.

摘要： The present invention relates to crude oil processing, particularly related to conversion of crude oil containing high amount of naphthenic acid compounds to lighter hydrocarbon materials with minimum capital expenditure. The invented process utilizes a novel scheme for high TAN crude oils by employing thermal cracking process to maximize the residue conversion to valuable products, which require minimum modifications in unit metallurgies and corrosion inhibitor injection schemes in refineries.

摘要： The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor and a reactor furnace for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking treatment in a coker furnace and a coking drums, resulting in reduction in overall coke yield.
