摘要

激光测绘是一种被广泛接受的获取焦炭筒壁表面轮廓以识别凸起的技术。所得到的数据用于跟踪和趋势血管扭曲,并映射以说明从基础半径和/或先前检查的血管形状。以准确和一致的方式监测这些变形随时间的发展和演变已被证明是预测焦炭鼓形诱发裂纹的有效工具。本文讨论了激光测绘技术中扫描仪定位、数据噪声、激光测距精度、数据缺失以及在胀形评定中的影响等问题。对基于二阶导数的分析的影响进行了详细的讨论,并讨论了使用技术来减少数据噪声和传感器运动的影响。

Importance of Accurate and Detailed Data Processing of Laser Mapping in Coke Drum
Laser mapping is a well-accepted technique for obtaining surface profiles of coke drum walls to identify bulges. The resulting data is used to track and trend vessel distortions and mapped to illustrate the shape of the vessel from a base radius and or previous inspection. Monitoring the development and evolution of these distortions over time in an accurate and consistent manner has been demonstrated to be an effective tool for predicting bulging induced crack in a coke drum. In this paper, the authors discuss several aspects of the laser mapping technique such as scanner positioning, data noise, laser range accuracy, missing data and the repercussions in the assessment of bulging. The effects on second derivative-based analysis are covered in detail and the use of techniques to reduce the effects of data noise and sensor motion are discussed.
