ADNOC deploys pioneering AI-enabled process optimization technology

Following successful initial operations, ADNOC announced the deployment of an industry leading artificial intelligence (AI)-enabled process optimization technology--Neuron 5--across all ADNOC facilities across thousands of critical pieces of equipment essential for production, including compressors, valves and generators.

Utilizing pilot plant operations for new chemical process technology development: A roadmap to scale up success and commercial plant safety

AVN Corp.: Clark, B.  |  Nunley, M.  |  Phillips, G.

To demonstrate a new chemical process technology (flowsheet, raw materials, product) or improve an existing one, pilot plants are designed and operated at a scale between laboratory benchtop and commercial scale—often with specific goals for operability, product quality, economics and process safety. Identifying where potential safety, technical risks or uncertainties may occur is always a key goal in evaluating a new process.

The purification of benzoic acid using dividing wall columns

Sulzer Chemtech: Yang, Q.  |  Ni, L-F.  |  Faessler, P.

In one recent project for a customer based in Asia, the authors’ company suggested the combination of distillation and crystallization techniques to obtain high-quality purified benzoic acid. Encouraged by the successful startup of this processing train, the customer began to schedule a second project. The authors’ company was asked to optimize the purification process to improve cost and operational efficiencies. The two existing columns, which remove lights and heavies, respectively, from the crude benzoic acid feedstock were investigated to identify key opportunities. The feasibility study based on the feed composition confirmed that the existing columns could be converted into a single dividing wall column (DWC).  

The attractive market opportunity for synthetic graphite: Graphite as an energy transition material (4)

Chevron Lummus Global: Antoniou, M.  |  Manral, V.  |  Magdoza, K.
Evalueserve: Suri, V.

Given the attractive demand projection, investors must understand the benefits and return on investment for natural and synthetic graphite routes. This article establishes the pros and cons for each, and specifically highlights the emerging opportunity for upgrading and repurposing smaller petcoke units to needle coke units, therefore contributing to fulfilling the rising demand for synthetic graphite.

Utilize a hydrogen reactions lab to optimize renewable fuels processing

Air Products and Chemicals, Inc.: Lebrecht, T.  |  Duhamel, D.

Leading technology developers in the refining space are utilizing various catalysts to enhance the adjusted reaction chemistry, but this does not directly address how to optimize hydrogen utilization for the hydrodeoxygenation and isomerization/cracking processing steps. To ensure the right equipment outlay and calibration for these hydrogenation applications, replicating the process in a lab setting can help identify efficiencies and yield improvements for a fraction of the cost that a refiner would incur attempting to achieve that optimization through modifications at commercial scale. 

Meet gasoline quality and process safety requirements through new alkylation technologies

Petrobras: Da Silva, M. W.

The catalytic alkylation process is very attractive to countries with high gasoline consumption and a sizable availability of LPG. This process can produce high-octane gasoline with low levels of contaminants, although there are high capital investment and operational costs associated with this technology.  

Case study: Developing mildew-resistant coatings on ethanol tanks

Sherwin-Williams Global Supply Chain: Hair, J.  |  Rook, T.

Scientists from the authors’ company determined how best to combat persistent black mildew on aboveground storage tanks by first using a novel strategy to identify it. This discovery led to the identification of coating formulations with superior capacity to prevent mildew growth. The scientists proved the performance of the coatings by conducting field tests involving painting sample patches onto an ethanol storage tank. 

The effects of cooling water parameters on condenser brass tubes

Tüpraş: Yıldız, D.

This work is focused on the effect of cooling water parameters on admiralty brass tubes. The effect of high free chlorine on the corrosion rate of brass tubes has been investigated by scanning electron microscopes (SEMs) and eddy current test (ECT) methods and the laboratory results of the cooling water were determined and discussed. Also, the tendency of the feed water scaling indices that is LSI, PSI & RSI was calculated. The results show that a dezincification corrosion mechanism was observed due to the high-level free chlorine on the admiralty brass tube.
