High-sulfur spray dryer Shawnee test program: Characterization of 10-MW spray-dryer electrostatic precipitator by-product: Final report

At IPC 2010 PII Pipeline Solutions (PII) presented the paper “VALIDATION OF LATEST GENERATION MFL IN-LINE INSPECTION TECHNOLOGY LEADS TO IMPROVED DETECTION AND SIZING SPECIFICATION FOR PINHOLES, PITTING, AXIAL GROOVING AND AXIAL SLOTTING”1, IPC 2010-31124. The suggestion was that this improvement would allow operators to make more informed pipeline integrity decisions in future. In the 4 years since this paper was presented many hundreds of runs have been completed with this latest generation MFL ILI technology, capturing information on tens of thousands of kilometers of pipe, and generating a significant volume of dig verification data. In collaboration with Oil & Gas pipeline operators around the world this growing dig verification database has been utilized to improve software models, algorithms, & analysis processes to validate and further enhance system detection, sizing, & reporting capabilities. This paper focuses on the recent collaboration between ExxonMobil and PII, to investigate system capabilities with respect to “Pinholes”, to address a known threat to a specific pipeline in the United Kingdom. This paper will describe the: • Evolution of the “Pinhole” specification that captured the interest of ExxonMobil. • Use of Finite Element models to predict entitlement for characterization of “Pinhole” type defects • Detail of and results from the ExxonMobil sponsored test program that was conducted in early 2013 • The in-line inspection, analysis report, and dig verification that followed for the pipeline in question. This joint paper, prepared and presented in collaboration by ExxonMobil & PII, will reflect the perspective and synergy of the Pipeline Owner/Operator and the ILI Vendor.

SOPRANOISE targets simplified assessment of the in-situ intrinsic acoustic performances of road / railway noise barriers. This paper presents its half-term progress. The research is divided in 5 Work Packages, the scientific ones being WP2 to WP5.WP2 is about establishing a state of art (SoA) of the intrinsic performances characterization: it is now finished and presented in 2 other papers by Conter and Fuchs. WP3 is about in-situ inspection tools: based on a review / questionnaire, an inspection protocol has been developed allowing simplified assessments mainly based on visual inspections and characterization of possible defects; WP3 is now in its final testing phase. WP4 is about designing a brand new "quick and safe methods" that could take place "in between" the inspection tools and the standardized EN1793-5 and 6; the research and development phases of WP4 are now finished, while its validation along highways is now scheduled. Finally, WP5 is about the use of noise barriers in the European market and the final report: a synthesis on the physical behavior of noise barriers and the physical significance of the test methods has been done, as well a SoA on the effective use of noise barriers; the results will be presented.
