2 How can we find out the problems inside towers, storage tanks and pipelines without shutting down and also not having the need to remove insulation? Why is tower not meeting the design condition? Is there tray damage in tower? Any foam or flooding? Any packing damaged? Any liquid mal-distribution? Any deposit in the pipeline? Where is the deposition? Any leak in heat exchanger?

3 Tracerco Diagnostics TM Service Non-intrusive On-line Diagnostics No lagging removal No impact on product and process while carrying out diagnostics Help you to see the internal condition of the vessel Reduce the time and cost With tower scan, the buildup in the internal of tower was known, then the info can help in the adjustment of process parameters and chemical injection to control the buildup. This avoid any unnecessary shutdown for maintenance, hence saving dollars loss during each shutdown. With TRACERCO Diagnostics services, it helps the plant to narrow down the problem of new tower commissioning where the diagnostics result used in the problem rectification helps in the optimization after. Using TRACERCO Diagnostics Separator Study, the study assist in the optimization that overcame rate limitations and separator malfunction which was worth >$1 million per day.

4 Service When to scan When need to scan Results Before shut down After Commissioning Assess tower operational conditions Identifying tray damage, feed pipe, outlet pipe Assess tray cleaning requirement Assess tray replacement need Assess gas-liquid separation Assess shut down maintenance results Assess on-line operational condition Assess on-line abnormal condition 1. Get information of the tower operating condition. 2. Make some preparations before cleaning or shut down, If there is foaming, you can add foam suppresser online, then rescan to see the effect of foam suppresser, save time and even do not need shut-down. If the packing is blocked, you can add chemicals online to clear the block, then rescan to see the effect of chemicals. 3. If it was flooding, you can determine the cause because of tray damage or feeding problems. 4. Save maintenance time as you can know how many trays were damaged before shutdown. 5. Identify the problem and provide the basis for project. 6. Checking the revamp effect and see the problem was solved or not Tray column scan During malfunction Assess tower operational condition Identifying internal equipment, such as feed pipe, out pipe and other important equipment Determining flooding high entrainment liquidvapor separation Before project Assessment tower operational condition Find out capacity or abnormal point After project Assess the effect Regular scan Assess the operational condition of each stages to analyse anomaly condition Assess the operational condition at different rate Measure liquid level Unstable Level measurement Level measurement was incorrect due to foam or slurry Given actual material level, including part of the foam. Measure deposit buildup in the pipe Regular measurement Sudden shut-down due to buildup Regular measure bulidup to plan shut down schedule. Crude oil storage tank scan Regular assessment Assess depth of deposit Provide depth of deposit Crude oil separator scan Regular assessment Assess deposit Provide the trend of deposit bulidup to assess shutdown time Leak test During malfunction Determining which heat-exchange was leak Determining which heat-exchange was leak, save maintenance time

5 Service When to scan When need to scan Results Packing column scan Before shut down After Commissioning During malfunction Before project Assess the tower operational condition Identifying of packing, distributor, draw out liquid situation Assess packing cleaning requirement Assess packing replacement requirement Assess liquid distribution Assess shut down maintenance results Assess on-line operational condition Assess on-line abnormal point Assess tower operational condition Identifying internal equipment, such as feed pipe, out pipe and other important equipment Determine the liquid flooding, mal-distribution Assess the tower operational condition Find out capacity or abnormal point 1. Get information of tower operating condition 2. Make some preparations before cleaning or shut down, If there is foaming, you can add foam suppresser online, then rescan to see the effect of foam suppresser, save time and even do not need shut-down. If the packing is blocked, you can add chemicals online to clear the blockage, then rescan to see the effect of chemicals. 3. If it was mal-distribution, you can know where the mal-distribution was present 4. Save maintenance time as you can know how may trays need to be replace and where the tray need to be replaced before shutdown 5. Distributor operating condition 6. Identify the problem before and provide the basis for project. 7. Checking the revamp effect and see the problem was solved or not After project Assess the project effect Regular scan Assess the operational condition of each stages to analyse anomaly condition Assess the operational condition at different rate During malfunction Determine blockage point Determine the blockage point quickly, saving maintenance time Pipe scan Regular scan Assess deposit buildup condition at each stages Assess liquid level inside of the pipe Provide sediment deposit trends, to assess shut down time Provide depth of liquid level in case that the liquid block the pipe
