What are the specific requirements regarding plant scale, raw material composition, and product quality for processes such as Lo-CAT desulfurization (H2S) and similar processes?
There aren’t many constraints; the main one is cost. When the sulfur production is less than 1.5 tons per day, using chelated iron for treatment is too expensive. If the sulfur production exceeds 10 tons, the equipment required becomes too large – the reactor diameter has to be big, which increases the cost significantly. There are basically no other constraints
I’m not sure if it’s possible to handle organic sulfur
The removal rate of organic sulfur by complexed iron is about 90%
It is not applicable for installations with a scale exceeding 10,000 tons. Organic sulfur cannot be guaranteed, and ammonia cannot be treated.
