Thanks a lot for sparing time in going ...Hi Tayeb,<br /><br />Thanks a lot for sparing time in going through the articles published on my technical blog. In response to your question, I would like to mention that the liquor velocity indicated as 1.5 to 3.5 m/s is the liquid velocity. However, the vapour velocity is taken between 5 to 8 m/s for design of vapour line of the evaporator.<br /><br />Hope, above clarifies your doubt.<br />Regards.<br /><br />Kunwar RajendraRajendra Kunwarhttps://www.blogger.com/profile/08671692608724278951noreply@blogger.comtag:blogger.com,1999:blog-8425476456019975806.post-30167762828311553622016-08-28T08:27:38.239-07:002016-08-28T08:27:38.239-07:00Hi Mr. Rajendra,

Considering the two phase flow inside the tube, What does the mentioned velocity range describe? vapor or liquid velocity? <br /><br />Kind Regards,<br />Muntaser Tayeb<br />Anonymoushttps://www.blogger.com/profile/05655762557137141668noreply@blogger.comtag:blogger.com,1999:blog-8425476456019975806.post-53287375569675092442014-11-30T21:44:41.651-08:002014-11-30T21:44:41.651-08:00Hi Mr. Hans Sauer,
Thank you very much for your in...Hi Mr. Hans Sauer,<br />Thank you very much for your intelligent and interesting question. You are well aware that the cost will depend on the unit price of fuel used for steam raising, boiler efficiency and steam economy of Evaporator installed in the plant. Let us assume that the Alumina refinery is using Coal having UHV of Coal as 5500 k.cal/kg at landed price of 120 US$/t. The steam-coal ratio in boiler will be around 6. If the steam economy of evaporator is 3.6. Then cost for removal of excessive water works out to US$ 5.80 [(1*120*1.04) /(3.6*6) = 5.80] per tonne of dilution removal.Here, 4% extra coal is assumed for bank firing and handling losses.<br />Regards. <br />Kunwar Rajendra <br />Rajendra Kunwarhttps://www.blogger.com/profile/08671692608724278951noreply@blogger.com
