Aug 05, 2019 · 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
Desulfurization is the removal of sulfur or sulfur compounds (as from coal or flue gas), mostly from fuels. The most commonly required desulfurization process is in natural gas, but it
Flue Gas Desulfurization (Acid Gas Removal) Systems Goal To familiarize you with the operation of flue gas desulfurization (FGD) systems that use a scrubbing liquid to absorb SO2 present in the exhaust gas stream. process equipment and could affect process chemistry or require prescrubbing.
1. a process for reducing the sulfur content of a sulfurcontaining heavy hydrocarbon oil, at least 50% by volume of said oil boils above 250*c., which comprises treating the oil with an oxidant to form compounds containing both oxygen and sulfur, said oxygen and sulfur being chemically combined, heating the treated oil containing said compounds at a temperature from about 350* c. to about 450
The process operates at atmospheric pressure, at ambient temperature and has no liquid discharge. The only process discharge is the sulfur cake which has a certain humidity content. The process operates continuously and only requires a periodical inspection and cleaning of some internal components to ensure optimum efficiency and performance.
Apr 23, 2019 · Specifics on how IUT''s desulfurization works have been previously discussed in these pages, but the company says in addition to its original ultrasonic treatment it has now added a second alytic stage to its desulfurization process that focuses on breaking down sulfur compounds in the feedstock into SO2.
