A wastewater is to be treated in a complete-mix reactor. Assuming that the reaction is irreversible and first-order (r=-kC) with a reaction rate coefficient equal to 0.15 d, determine the flowrate that can be treated if the reactor has a volume of 20 m' and 98 percent treatment efficiency is required. What volume would be required to treat the flowrate determined above if the required treatment efficiency is 92 percent?

Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.
