{"product_id":"troubleshooting-vacuum-systems","title":"Troubleshooting Vacuum Systems","description":"\u003cp\u003eVacuum systems are in wide spread use in the petrochemical plants, petroleum refineries and power generation plants. The existing texts on this subject are theoretical in nature and only deal with how the equipment functions when in good mechanical conditions, from the viewpoint of the equipment vendor. Also, the existing texts fail to consider the interaction of the vacuum system with the process equipment it serves and the variability of the motive steam conditions, change in cooling water temperature condenser fouling and \u003ci\u003eerosion\u003c\/i\u003e of the ejectors.\u003c\/p\u003e \u003cp\u003eHere are some of the many questions answered in this groundbreaking volume:\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003eWhy does my first stage jet make a surging sound during hot weather?\u003c\/li\u003e\n\u003cli\u003eWhy does the vacuum suddenly break?\u003c\/li\u003e\n\u003cli\u003eI've seen moisture condensing on the jet's body! What’s causing that?\u003c\/li\u003e\n\u003cli\u003eWhy do I have to steam-out the drain legs from our condensers?\u003c\/li\u003e\n\u003cli\u003eSuperheated steam is making our vacuum worse.

But why?\u003c\/li\u003e\n\u003cli\u003eI can't pull the pre-condenser bundle. The shell side is fouling. What should I do?\u003c\/li\u003e\n\u003cli\u003eWe're not getting our normal horsepower from our steam turbine.

Is there an explanation for this?\u003c\/li\u003e\n\u003cli\u003eOur turbine exhaust steam pressure to our surface condenser has doubled in the last two years. What should we do?\u003c\/li\u003e\n\u003cli\u003eRestricting cooling water flow from our elevated condensers improves vacuum!
