High-quality graphite/needle grade coke is produced with reduced impurity levels and improved coefficient of thermal expansion using an integrated hydrotreatment, catalytic cracking and coking reaction sections, employing a combination of highly paraffinic hydrotreated VGO stream and aromatic CLO stream, which is thereafter processed in a delayed coking section.

Process for production of needle coke

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.

Process for conversion of high acidic crude oils

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 for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking in delayed coking process, resulting in reduction in overall coke yield.

Delayed coking process with pre-cracking reactor

The present subject matter describes a method and apparatus for operating a delayed coker. The method comprises contacting a vapour produced in a delayed coker-drum with a catalyst maintained in form of a bed, and maintaining a level of said catalyst-bed within pre-defined limits during catalytic-cracking of the vapour. Thereafter, the cracked-vapour is routed to a coker-fractionator column to trigger conversion into one or more hydrocarbon products.

Delayed coker drum and method of operating thereof

The present invention provides a delayed coking process comprising a step of subjecting a mixed feed comprises residual heavy hydrocarbon feedstock and bio oil obtained from fast pyrolysis of lignocellulosic biomass of one or more of Jatropha, Cashew nut, Karanjia and Neem to a delayed coking process and a system for the delayed coking process.
