Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas ...

Jeri Sullivan Scrubbers can be used to help desulfurize the exhaust from power plants. Desulfurization is the process of removing sulfur from something to prevent contamination. Also known as hydrodesulfurization or HDS, this chemical process reduces the sulfur dioxide emissions and converts them to sulfuric acid. The sulfuric acid is then used in car batteries and fertilizer.
