Does anyone knowledgeable know the steam temperature and pressure ratings at the inlet and outlet of a carbon dioxide compressor turbine, what types of steam are involved with the turbine, and their flow paths? Thank you

The carbon dioxide compressor drive turbine in the American-Holland type large nitrogen fertilizer plant is a single-cylinder, steam-extraction, steam-injection, and condensing turbine manufactured by the Italian company Nuovo Pignone. The turbine consists of two rows of impulse stages and five rows of reaction stages, and it is one of the key equipment in urea production plants.

The main steam pressure is usually 3.8 or 5.6, while the extraction pressure is around 2.5. Some turbines have air injection systems while others do not; the exhaust pressure is approximately 10 KPa
Our plant produces 520,000 tons of urea; the main steam temperature is 410 degrees, and the pressure is 4.0 G. The turbine exhaust conditions are 11 KPA(a) and 47 degrees.
We use Hitachi machines; the main steam temperature is around 430 degrees, the pressure is 4.2 megapascals, the extraction steam pressure is 2.7 megapascals, and the injection gas pressure is 0.36 megapascals!
