How is the mass flow rate in a catalytic cracking unit calculated?
Thread Content
I am carrying out a calculation of the hazardous materials for a plant with a capacity of 500,000 tons. The goal is to determine the amount of hazardous substances present in the plant, including gasoline, diesel, liquefied gas, etc. At present, I only know the flow rates of these materials; for example, the flow rate of the reaction gas is 49,896 kg/h. How can I calculate the quantities of each substance in the plant? Should it be calculated based on the volume of each device? Are there any coefficients? For example, how is the amount of gasoline in a fractionation tower or stabilizer calculated? :L Thank you!
It’s simple once you know the total amount of feed. Based on your design, the normal operating hours per year are usually 8,000 hours; from this, you can determine the feed rate per hour. Then, using the product yield, you can proceed with the calculations step by step
Did I not make it clear? The amount per hour is known; what I want to know is the amount of material remaining inside the equipment, to determine how dangerous it is.
