Reduce gasoline blending giveaway with inline blending and online analyzers

Refinery Automation Institute, LLC: Curcio, E.  |  Barsamian, A.

With best available technology, how much practical reduction in giveaway can be achieved, with the caveat that there is no such thing as “zero error” in value measurements? Also, can those numbers change if inline blending is used? This article seeks to answer both questions.

<i>Hydrocarbon Processing</i>, the downstream processing sector’s leading technical publication, has announced the winners for its third annual awards.

How valve upgrades can improve tank and terminal facility operations

Emerson: Leavitt, D.  |  Arroyo, M.

Tank and terminal facility profitability ultimately rests on a handful of key performance indicators (KPIs). The ability to maximize tank capacity utilization—while minimizing the time it takes to load and unload ships, trucks and rail cars—drives the bottom line. All those transfers must happen quickly and accurately, while avoiding product contamination.

Catalyst breakthrough for ethylene production

Clariant Catalysts: Vianna, C.  |  Adams, D.

In a growing and competitive industry, ethylene producers are turning to catalyst suppliers for solutions to innovate. Until recently, a solution to the difficulties inherent to acetylene hydrogenation in ethylene plants has challenged the catalyst industry. Due to their lower total production cost, “front-end” process flowsheets are now predominantly selected for new projects.

Driving FCCU value through fresh and flushing catalyst activity modeling

BASF: Shackleford, A.  |  Tan, A.  |  Eren, B.

Refiners are continually challenged to maximize economic gain in the face of cost pressures and plant operating constraints. The fluidized catalytic cracking unit (FCCU) plays an integral role in the optimization of the facility. FCC catalyst is often one of the largest budget items in the refinery. Therefore, the balance between FCCU performance and catalyst costs has a significant impact on refinery profitability.

Taking back what’s yours: Extractive desulfurization minimizes octane loss in FCC naphtha hydrotreating

INVISTA Performance Technologies: Aggus, B.  |  Massa, M.

Generating octane barrels has always been a tough road for refiners. In 2020, this road got a lot tougher with olefin saturation and octane destruction being collateral damage as refiners strive to achieve the sulfur limit in the gasoline pool.

Catalytic processes operation during downturns in aromatics complexes

ExxonMobil Chemical Co.: Andrews, J.  |  Hung, J.  |  Molinier, M.  |  Lim, Y. T.

Paraxylene production is a highly cyclical business that is subject to changes in the global economy and dependent on feedstock costs, alternative dispositions for aromatics, utilities costs and plant locations, among other factors. With the large PX capacity added by recently started crude-to-chemicals complexes and the expected impact of the economic recession on commodities demand, many aromatics complexes face a significant slowdown in the coming months or, possibly, years.

Conventional FCC to maximum propylene production

TechnipFMC Process Technology: Singh, R.  |  Lai, S.  |  Dharia, D.
W. R. Grace: Cipriano, B.  |  Hunt, D.

Fluid catalytic cracking is one of the most important conversion processes used in refineries. This process converts heavy petroleum fractions into lighter, higher-value products, such as gasoline, propylene and others.

Business Trends: Autonomous operations in process manufacturing—Part 1

IBM Corp.: Agnihotri, R.

Progress in the driverless car segment has served to illuminate one of the major future goals in industrial and process manufacturing: autonomous operations in process plants—in other words, the autonomous plant. While AO for process plants has received interest from the process automation and control industry, limited serious discussion has taken place in the process operations and IT domains.
