The flow rate of vegetable oil was 160 microliters/min (vegetable oils molecular weight is 883 g/mol and density of 0.875 g/mL). The flow rate of the alcohol catalyst is 80 microliters/min with a molecular weight of 32.04 g/mol and a density of 0.79. Based on the flow rate of vegetable oil, what is the theoretical yield of biodiesel for flow reaction in mmol and mg?

P5.75 An absorber treats a gas stream containing 22.5 gnon 2.5 gmol/min carbon dioxide with an aqueous stream with proprietuly additives that is flowing at 50 gmolMnin. The process is currently ope recovers 80% of the CO, fed to the aqueous stream. (a) Determine a value for the equilibrium distribution coefficient between the aqueous and gas streams (moles CO,/mole liquid/moles CO,/ mole gas). b) We'd like to improve the separation performance of the absorber. Frannie proposes using a new superadditive that increases the CO, solubility in the aqueous phase (increases the distribution coefficient) by 10%, that can be mixed with the incoming liquid stream. What is % recovery of CO, if the new additive is used? Zooey suggests stay- ing with the original aqueous solution, but splitting the liquid feed into two equal streams and operating two separators in a cross- current mode, as shown in the figure. You may still assume that, in each separator, the exiting liquid is in equilibrium with…

A medlcal techniclan Is working with the four samples of radlonuclides llsted In the table below. Initlally, each sample contains 8.00 umol of the radionuclide. First, order the samples by decreasing Initial radioactivity. Then calculate how long it will take for the amount of radionuclide in each sample to decrease to 1/8 of the initial amount. time for amount of radlonucllde to decrease to 1/8 of Initial amount radlonucllde Inltlal sample radloactivity symbol half-llfe 51 46.0 minutes 1 (highest) v |minutes Mn 25 96 Tc 4.0 days days B. 43 99 |hours 66.0 hours Mo 42 103 Pd 17. days 4 (lowest) | days D. 46 Check Privacy Accessi Explanation 2021 McGraw-Hill Education.
