Everyone, calculate the alkali consumption
Thread Content
LPG alkaline desulfurization (without alkanolamines): LPG volume of 680 T/d, sulfur content of 5000 mg/m3. With an alkali concentration of 3%, let’s calculate how much alkali is used per day
It depends on what type of sulfur is present; generally, liquefied gas contains a high amount of inorganic sulfur, and calculations are based on this inorganic sulfur. One molecule of inorganic sulfur requires two molecules of base. Approximately 6.8 T of base may be consumed per day
6.7T – Just by looking at the number, one can tell it’s incorrect; several factors need to be taken into consideration: 1. The reaction between the alkali solution and S should be calculated using molar amounts. 2. The alkali solution will not be completely consumed. 3. The unit for sulfur content in liquid hydrocarbons is mg/m3, and the density of liquid hydrocarbons to be considered is 0.55 t/m3.
