Casting Quality Issues in HF Alky Valves

HF Alkylation


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.

Case for Carbon Intensity Improvement for Gasoline Units

Sustainability, Gasoline Processing


The carbon intensity of Reforming Units is inherently one of the higher processes in the refinery due to its energy requirements. This presentation will explore ways to improve carbon intensity with various equipment upgrades, as well as showing the positive impact that optimal catalyst performance can have on reducing Carbon Intensity.

Testing and Modelling Crude Oil Compatibility

Crude


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.
