Industry Perspectives: Petrochemicals surge despite possible future roadblocks
Over the past several years, investments in petrochemicals capacity additions have skyrocketed. Hundreds of billions of dollars have and will be invested in additional petrochemicals units and complexes.
FCCU catalyst reformulations: Reducing risk and guaranteeing value with collaboration/testing
Hellenic Petroleum S.A.’s Aspropyrgos refinery is located near Athens, Greece. It has a total refining capacity of approximately 7.5 MMtpy and a Nelson complexity index of 9.7. The refinery was built in 1958 and has undergone several upgrades, including the installation of a fluid catalytic cracking unit (FCCU).
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.
A new liquid-phase isomerization process for xylene loop debottleneck and energy savings
In a typical xylene loop, C<sub>8</sub> aromatics are fractionated out of a heavy reformate C<sub>8</sub>+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C<sub>8</sub> aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.
Can ammonia be a future energy storage solution?
Ammonia is well known as a fertilizer. However, it is also a potential carbon-free fuel and an excellent solution for storage of renewable electricity, especially if the syngas needed for producing the ammonia is made by electrolysis.
IMO 2020 stability and compatibility headaches
The year 2020 will be a mess from the fuel oil stability and compatibility points of view. The year will be price-driven, so the temptation to “cut corners” is great—meaning that a highly variable number of blend components to manufacture the fuel oil will open a “Pandora’s box” of complex and questionable fuel formulations.
Industry Perspectives: There’s still time to vote for the best!
The nominees for the 2019 Top Project awards are out. Using <i>Hydrocarbon Processing’s</i> Construction Boxscore Database, the editors have identified nine projects that are anticipated to significantly impact the global or regional downstream industries.
Editorial Comment: Honoring the industry’s best … take 2!
Due to Tropical Storm Imelda, Hydrocarbon Processing issued its first force majeure in postponing the third annual HP Awards.
FCC catalyst deactivation studies to mimic refinery conditions for high-propylene applications
The fluid catalytic cracking unit (FCCU) is a conversion unit located at the heart of many refineries. Its main purpose is to crack crude oil-derived feedstocks into valuable liquid products, primarily LPGs (propylene and butylenes), and gasoline and light-cycle oil (LCO) precursors. The process uses a fluidizable catalyst, comprising an alumina-silica framework and tailored for each refinery to meet its specific needs. Often, the changing of a catalyst includes catalyst testing evaluations, employed by about 50% of the FCCUs in the world. The testing process is cumbersome, in which multiple methods are available to refineries.
