WebThere are three main operational concerns with VTTR that are not encountered with other exchanger operations: Startup: Because boiling the fluid in the reboiler is needed to start the circulation, and effective boiling is only possible once circulation is established, we are left with a chicken-and-egg problem. WebAug 5, 2013 · The demethanizer and the stabilizer both have a design pressures of 450 psig. Therefore, the existing piping and equipment should be able to handle the elevated feed pressure. Based on process... WebThis is because for a given ethane recovery percentage, the proposed process allows the demethanizer to operate at a temperature and pressure higher than that of a conventional process. Such higher operating temperature and pressure places the system operating conditions further away from the conditions under which solid carbon dioxide forms. atalanda halle
