Sodium Hydroxide-Based CO2 Direct Air Capture for Soda Ash Production …
This work introduces the principles and supplies the first key parameters for replacing the conventional ammonia-soda (Solvay) process with a new environmentally friendly and sustainable process. For this, the absorption of diluted CO2 (0.0153–1.2 vol %) in carbonated NaOH solutions was experimentally studied in a temperature range relevant …

Blast furnace process
Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.

Options for CO2 capture from SMR
Whenever a hydrocarbon is converted to hydrogen, there is a concurrent production of by-product carbon dioxide (CO 2). Historically, SMRs have been designed to optimise capital, operating costs and plant reliability. ... A simplified block flow diagram of the SMR process is shown in Figure 1. It can be seen in Figure 1 that CO 2 is present in ...
