What are the molecular weights of the crude steam, stabilized steam, and the rich gas entering the absorption tower (what values are generally used)? What is the liquid-to-gas ratio of your unit?
Using the mass ratio directly is also fine, and it’s easier to calculate. For crude gasoline and stabilized gasoline, data is collected directly in terms of mass units. The rich gas entering the absorption tower is generally expressed in standard cubic meters; by analyzing its density, the mass can be determined, and thus the values can be calculated. The liquid-to-gas ratio in our unit is between 1.5 and 2.0.
