Hydrocracking

Steam generator in a hydrocracker high-pressure loop—why not?

Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker.

Rovuma LNG, a JV comprised of ExxonMobil, Eni and China National Petroleum Corp., will likely delay its final investment decision (FID) on the group’s $30-B Mozambique LNG project.

Octane enhancement avoiding both high reformer severity and alkylation

Kauders, P., CDE Projects Ltd.

An innovative refinery process arrangementa converts butane-rich, light paraffinic streams—preferably containing a high proportion of isobutane—into butylene by dehydrogenation.

Optimization study in hydrocracker unit using simulation model

Hydrocrackers are key refinery units that convert heavy feed components into valuable lighter products. The profitability of these units is directly related to this conversion level. Conversion reactions take place in a nearly pure hydrogen environment, with the help of selective catalysts, under high pressure and high temperature. The products of the unit are separated in the fractionator section. Unconverted oil taken from the fractionator bottoms reveals the conversion performance of the unit.

HP Top Project Awards

The editors of Hydrocarbon Processing have identified nine projects that are anticipated to significantly impact the global or regional downstream industries. The winners and nominees of the HP Top Project awards will have a considerable impact on the HPI, whether through CAPEX, satisfying domestic or regional demand, diversifying product offerings, or adding to the resurgence in refining and/or petrochemical processing capacity.

Diversifying the future: Incentives for worldwide adoption of renewable fuels and chemicals—Part 2

Bio-based, renewable fuels and chemicals can reduce the environmental footprint of maintaining global transportation and product demands, while also offering supplementation of traditional fossil fuels in a global environment with increasing energy demand. The renewable energy sector is large and growing rapidly.
