I know this topic has been started a lot of times before. Actually I used "search" button but haven't found precise answer. We have a particular problem with predicted erosion velocity in steam condensate header of an existing petroleum unit. To get to know steam traps pressure drop we use simulation software - it helps us to save time. Software we use is designed for plant piping systems and it suggests to calculate erosion velocity according to API 14E. We knew that coefficient C in API 14E is conventional and C value has been criticised but it gave us a some safety margine. All was OK and software gave us reasonable results till now.
In current steam condensate header model we encountered that predicted erosion velocity of two phase flow is equal 6-10 m/s. My questions are next:
1. API 14E is designed for oil and gas pipilines. Could it be implemented for other service: steam, chemicals, refining processes?
2. Erosion prediction in API 14 is designed for two phase flow. Could it be implemented for near gas conditions, for example saturated steam, saturated vapors? Could it be implemented for all liquid conditions?
3. Are there any worth engineering (not academic) sources to know more about erosion prediction? Sorry, I understand that a lot of researches have been done and subsequent books and theses have been written. But we operate with real life and real pipe, I need more engineering instead of scientific.
4. What would you do for steam condensate header check? What are your practices? And the most important - what are the reasons and sources of your practices?
5. What software do you use for inplant hydraulic systems? Which of industry is yours (storage/refinery/petrochemical/chemical/fertilizers/energy)?
P.S. Sorry for language - I have seldom practice. You can state which part of text is hard to take.
