WitrynaNaphthenes. Naphthenes (Cn H 2n) have the same formula as olefins, but their characteristics are significantly different. Unlike olefins, which are straight-chain … WitrynaResearch at Exxon Chemical Co. has shown that asphaltene precipitation and subsequent carbonization is the major mechanism in crude oil heat exchanger fouling. Exchangers that foul frequently must be cleaned on a regular basis. In the worst case, furnace-limited refiners may have to cut crude-charging rates as preheat fouling …

WitrynaAs with many problems, prevention is typically a much more effective control than subsequent treatment. As such, the preferred solution for column fouling is to keep the fouling material out of the process and equipment itself. Many processes actually use some sort of filtration to accomplish this. One good example is with amine contactors … WitrynaThe LIFESPAN fouling and stability and control programs use a practical, systematic approach to address your heat exchanger fouling issues. This begins with a thorough unit survey that gathers operational and mechanical data, reviews your equipment operating history, and collects process samples. Proprietary testing programs then … budget equasions for googe sheets
