Cracker output is given as:
▪️ 998,000 tonnes of ethylene
▪️ 420,000 tonnes of propylene

Feedstock is LPG and Naphtha as communicated by Technip and as per Environmental License mentioning storage for LPG and Naphtha but nothing about ethane/propane. LPG is assumed to be a blend of Propane and Butane.  

We use the following cracking yields:
▪️ Propane: 42% ethylene, 16.8% propylene
▪️ Butane: 40% ethylene, 17.3% propylene
▪️ Naphtha: 33.6% ethylene, 15.6% propylene

Let's again assume a 50/50 mix of propane and butane in the LPG for our initial calculation, we get approximately:
▪️ Naphtha: 2,130,000 tonnes
▪️ LPG: 1,150,000 tonnes
▪️ Total feedstock: 3,280,000 tonnes
The naphtha to LPG ratio is about 65:35.

This would be the world's ever largest cracker built, which Technip would have advertised if that was really the case. The company actually mentions that world's largest cracker capacity is 2,000,000 tonnes (of ethylene) in case of an ethane cracker , which corresponds to 2,500,000 tonnes of ethane feedstock). Something quite does not match  with the provided production capacity figures, especially for the cracker plant.

What can the actual plants capacities be?
