Synthetic graphite demand drives attractive techno-economics for coker upgrades
This article describes the economic opportunity that synthetic graphite demand growth presents for American and European refiners. It describes the conditions that best suit a plant to be considered for such a revamp. The article also discusses the modifications needed in capital equipment, process conditions and feedstock to execute this change, the typical capital expenditure required to materialize it, and the transformational gross profit enhancements that could result from these modifications, given the product slate upgrade.

Marathon to run refineries at 90% of combined capacity in Q3
U.S. crude oil refiner Marathon Petroleum plans to operate its 13 refineries at 90% of their combined 3 MMbpd capacity in the third quarter.
EIA: U.S. refining capacity increased in 2023 with expansions and existing facilities
U.S. refining capacity increased in 2023 for the second time since the COVID-19 pandemic, according to the U.S. EIA’s annual Refinery Capacity Report. U.S. operable atmospheric crude oil distillation capacity totaled 18.4 MMbpd at the start of 2024, a 2% increase compared with the start of 2023.
The distinct operational advantages of alumina-supported catalysts for hydrocracker pretreat and hydrotreating applications
Hydroprocessing units in refineries process crude oil feedstocks in the presence of hydrogen and catalysts at high temperatures and pressures to produce clean fuels (i.e., gasoline, diesel, jet) while meeting stringent environmental standards dictated by U.S. and EU frameworks.
Evaluating pressure recovery turbines as a clean energy solution
Petroleum refining is an energy intensive process. Although the level of energy efficiency, in general, is relatively higher in oil refining compared to the steel or cement sectors, there is still a scope for improvement.
A multi-objective optimization study for an integrated oil refinery-petrochemical plant—Part 2
In this research, the integration of an oil refinery and an ethylene-producing facility was examined using a mixed-integer nonlinear programming model that prioritized maximizing ethylene and propylene production and net profit.
