Steam turbine flow path drainage system under different operating conditions [PDF]
MATEC Web of Conferences, 2022 One of the important elements of anti-erosion protection of the steam turbine last blades is the use of hollow stator blades. There are grooves on the blade surface that lead the steam mixture inside the blades. This mixture is blown to the diffuser area.

Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path
Angewandte Chemie, EarlyView.One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.
