Aqueous Corrosion in Renewable Fuel Processing Units (424)  

No tool exist for predicting the corrosivity in the aqueous streams in renewable fuel processing units. The aqueous phase contains a combination of chemicals (CO, CO2, H2S, NH3 and HCl) which are all outside of the existing available models. The goal is to better understand the limits for corrosion resistant alloys under the aqueous conditions present in renewable fuel processing units

Measurement and Correlation of Wear Resistance (427)  

There are numerous standard ASTM test methods for determining the relative resistance of materials or surface treatments to impingement, dry sliding wear, and wet reciprocating wear, however, there is no established correlation between a material’s mechanical properties and its wear resistance. The relationship between such wear tests and actual wear performance in equipment is unclear. The objective of this project is to develop approaches to predict wear rates for a range of materials frequently used in the process industries over a range of abrasion Indices and different types of wear.

Metal Additive Manufacturing Qualification for ASME BPVC (386)  

Additive Manufacturing (AM) provides designers the ability to build parts directly from computer-aided design (CAD) files. Metal AM technology is rapidly maturing and offers a range of benefits to reduce cost, schedule and increase performance of Boiler and Pressure Vessel (BPV) systems. The impact to the BPV industry has been limited by the availability of standards. The project objective is to use this effort to validate the qualification for materials used in fabrication of BVP equipment. This project will be authorized in two phases: Phase 1: Qualify an additive material manufacturing procedure using GMA-DED method and ER-2594 filler metal in accordance with the requirements of Section 6 in ASME Code Case (Record Number 22-1598) and ASME Section IX, Part QW, Article VI. Phase 2: Fabricate a test pressure vessel with the Phase 1 results and test it according to MTI provided design using GMA-DED in compliance with ASME Code Case (Record Number 22-1598) sections 1-14 requirements, and supplemental MTI requested test methods.

New Test Method for Titanium Hydriding (310)  

This project will search for a firm that is able to non-destructively detect titanium hydriding in plant equipment. Past MTI titanium hydride projects looked at one specific method with the aim to adapt the method to identify titanium hydriding. This project has a much broader perspective aiming to test all techniques that have the potential to detect titanium hydriding. Industry information suggests that a method already exists. A few companies indicate they can non-destructively detect titanium hydriding. With the goal of discovering the best method to detect titanium hydriding, the project team intends to find out if these firms can prove their techniques.

Pressure Swing Adsorber (PSA) Vessels Structural Integrity and Fatigue ...  

PSA (pressure swing adsorption) pressure vessels are often used in the purification of hydrogen after syngas production. These vessels are manufactured from carbon steel and are welded in accordance to design codes and standards. Due to fluctuations in pressure, these vessels are usually affected by fatigue damage which can be accelerated due to exposure to hydrogen. The purpose of this project is to establish a relevant materials database for PSA steel in hydrogen that will be useful for predicting performance and lifetime.
