Hydrogenation Reactor

A life monitoring and assessment system of pressure vessels and piping in petrochemical plants has been developed based on the structural integrity theory and web technology. Two industrial cases of the monitoring system are given in this paper for hydrogen processing reactor, hydrogen pipeline and furnace tube of hydrogen reformer. The monitoring system is established to predict hydrogen embrittlement for the wall materials of hydrogenation reactor and pipeline in petrochemical plants. A critical description of hydrogen induced cracking is introduced to set up a criterion for the embrittlement. The electrochemistry hydrogen sensor is designed for its feasibility of real-time monitoring and assessment of hydrogen embrittlement for the equipment. It is pursued by the research to make a more impersonal judgment of safety of the hydrogenation reactor with real time tracing of operation. A remote inspection system is created based on computer network technology to monitor the plant subjected to hydrogen attack. The on-line system is also founded to monitor the operation of the furnace tube of hydrogen reformer and predict its residual life. The system executes in the remote server to assess the life of the tube and issue the information through the internet. Therefore remote users can monitor and manage the tubes on real-time. A non-contacting temperature monitoring technique is introduced into the system using CCD camera. An assessment method is introduced in this paper to create a correspondent relationship between remaining life and damage accumulation. It is significant for the method to describe the tube damage or materials degradation under unstable operations including varied pressure, varied temperature, over-heat or thermal fatigue, etc. A life fraction model related to damage accumulation is adapted into a real time monitoring system to calculate the residual life for a selected tube and work out an optimum preventive maintenance project.

Actual trends in machinery maintenance point to the necessity of an on-line real-time monitoring of the condition of the lubricant oil. Excessive delay in replacing the lubricant oil can have catastrophic results, whereas doing it too early produces evident economic and environmental issues. Magnetoelastic materials offer a good sensing principle for assessing lubricant oil viscosity; which is one of the most important properties to assure its proper lubricant capacity. Among others, one of the most remarkable properties of this sensing principle is the capability of being used through a wide viscosity range. In this work, we describe the experiments performed to evaluate the usefulness of this technology for testing the viscosity of different test oils in order to develop a working device for on-line, real-time monitoring the quality of lubricant oils.
