Many refiners are processing larger volumes of attractively priced unconventional crudes produced from fracking operations. Contain polymers and other additives that upstream processors are often used to enhance oil recovery or address hydraulic limitations in their operations. These additives can disrupt refining unit operations such as Crude Desalters or restrict the ability of the refiner to meet key product specifications such as JFTOT or NACE Spindle Corrosion test.

Over the last few years, there has been an increase in through body leaks on cast HF Alkylation valves. This presentation will review several real life examples of casting failures on valves in HF Alkylation service including cross sections of the failure location. These failures have occurred on both low RE carbon steel and Alloy 400 (M35-1) castings. Some common causes of casting failures will be reviewed including sand inclusions, porosity and varying levels of shrinkage. Common locations of casting quality issues with HF Alkylation valves will be discussed including the bottom bowl area and the body to end flange transition on Alloy 400 plug valves. The presentation will also cover some of the methods that are being implemented in the industry to improve the casting quality of HF Alkylation valves along with efforts to standardize and consolidate requirements for these valves.
Processing crudes from different sources leaves the possibility of blending incompatible mixtures. Compatibility models uses correlations to estimate the potential to create incompatible mixtures. Understanding the potential for compatibility effects without physically testing the crude provides the ability to choose the crude mix and purchase it while the market factors are favorable and the ability to safely purchase distressed cargos. The paper will discuss the basis of model correlations and the application to actual blends.
Successfully processing a changing crude diet can be a challenge from the tank farm through distillation. Upsets and performance reductions lead to processing cost penalties downstream, loss of production, and environmental impacts through greater emissions and brine water quality issues. Optimizing the design, operational parameters and chemical injection schema from crude receipts through the hot train can minimize these cost penalties and ensure performance is maintained.

Join this session to hear the latest on API's 5th edition of Recommended Practice (RP) 751, Safe Operation of Hydrofluoric Acid Alkylation Unit. In this session, we're discussing maintenance from the operator perspective, integrity management and other safety programs for hydrofluoric (HF) acid alkylation units.
Net Zero CO2 emissions by 2050 will require large investments in the oil industry on technologies. New technologies must be developed to reach the target but still need to scale up and mature. Improving the performance of Existing Assets will contribute to reduce the impact on carbon footprint now and advancements in cleaning techniques can restore more lost heat transfer more efficiently than traditional methods.
Petroval will discuss technologies to preserve heat transfer by maintaining clean surfaces further into the run, while Clean as New will discuss the varying benefits & limitations of techniques to restore lost heat transfer from fouling.
