Typically, for a stripper with 20 trays the reboiler duties will be as follows: MEA system —1000-1200 Btu/lbs (280-330 MJ/m 3) lean solution. DEA system —900-1000 Btu/lbs (250-280 MJ/m 3) lean solution.
WebReflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial and laboratory distillations. It is also used in chemistry to supply energy to reactions over a long period of time. How is reflux different from distillation? WebThis technique is useful for performing chemical reactions under controlled conditions that require substantial time for completion. The diagram shows a typical reflux apparatus for …
WebFeb 2, 2011 · The reflux ratio is defined as the ratio of the liquid returned to the column divided by the liquid removed as product, i.e., R = L c /D. Figure 2 also shows the column as a series of theoretical plates. A theoretical plate is defined as a vapor-liquid contacting device such that the vapor leaves it in equilibrium with the liquid which leaves it.
Webwhere R is the reflux ratio and α is the relative volatility of the two components. In this case, we will assume a reflux ratio of 2.5 and use the relative volatility data provided to calculate the number of theoretical plates required. The relative volatility (α) is defined as the ratio of the vapor pressures of the two components: chris jalilian dermatologyWebReflux Rate.
