We are considering vapor recompression to upgrade the heat quality of a waste vapor stream so that it would be easier to integrate with existing proceses for heat recovery. I am looking for information on pros and cons of this as well as what issues may prevent this technology from being...
I am working to justify repairing steam leaks in the plant. Can anyone help me with a calculation method or table to determine the rate of steam loss through leaks to atmosphere? Would RO calculations be sufficient? I think it would be easier with a table using plume size and steam pressure...
I am considering funding a pinch study in my chemical operations. I've got a $300 million/year energy bill (steam, gas, coal, KWH, etc)Does anyone have experience with this? What were the outcomes? Did projects get installed as a result?
We have several banks of Air Cooled Heat Exchangers (FinFans). They are used to control the temperature of a closed loop tempered water system. They are designed for 11MMBTU heat removal per bank. They've been in service for over 20 years. They are installed approximately 15 feet above grade...
I have a relatively small column with 10 bubble cap trays. It is in a dirty service with approximately 1% phenolic tars. Feed is 96% toluene and ~2% each of water and methanol. Feed enters on top tray and there is no reflux. Solvent and tars are the bottoms. Over time the bubble caps get...
Does anybody have a quick and dirty method for estimating energy losses due to poor condition or lack of insulation? I have varying line sizes and varying process fluid temperatures. Thanks
