Wash the recovered exhaust gas with dimethyl sulfoxide

A few questions: 1. What kind of exhaust gas is meant here? Which part’s exhaust gas? 2. Where does the sulfur dioxide obtained through flash evaporation go, and how is it treated? 3. What processes, and where are the achievements?

Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, with the formula (CH3)2SO. At room temperature, it is a colorless, odorless, transparent liquid; it is also a hygroscopic and flammable liquid. It features high polarity, a high boiling point, good thermal stability, and water solubility; it is soluble in most organic substances and is known as the \"universal solvent\". http://image68.360doc.com/DownloadImg/2014/01/1616/38322845_2.jpg DMSO ball-and-stick model. DMSO is dimethyl sulfoxide, which has a wide range of applications. Used as a solvent for acetylene, aromatics, sulfur dioxide, and other gases, as well as a solvent for acrylic fibers. It has extremely strong penetration into the skin, which helps drugs penetrate the body. It can also be used as an additive in pesticides. It is also a very important chemical reagent. DMSO is also an osmoprotectant that can lower the freezing point of cells, reduce the formation of ice crystals, mitigate damage to cells caused by free radicals, and alter the permeability of biological membranes to electrolytes, drugs, toxins, and metabolic products. However, studies have shown that DMSO has certain toxic effects; it interacts with the hydrophobic groups of proteins, leading to protein denaturation, and it possesses vascular toxicity as well as hepatotoxicity and nephrotoxicity. DMSO has certain toxic effects; it is necessary to prevent its evaporation when using it. 1%-5% ammonia solution should be kept on hand, and in the event of skin contact, the area should be washed thoroughly with water as well as diluted ammonia solution. The most common symptoms include nausea, vomiting, rashes, as well as a garlic, onion, or oyster-like odor on the skin and in exhaled breath. Inhalation: High vapor concentrations may cause headaches, dizziness, and drowsiness. Skin: It can burn the skin and cause stinging sensations, as seen in rashes and blisters. A thermal reaction occurs when dimethyl sulfoxide comes into contact with moist skin. It is necessary to avoid contact with dimethyl sulfoxide solutions containing toxic ingredients or substances, as their toxicity is not well known; moreover, dimethyl sulfoxide can penetrate the skin and, under certain conditions, introduce toxic substances into it. Absorption: The risk of absorption is very low.

The sulfur recovery off-gases, from which the vaporized sulfur dioxide is recovered, are returned to the sulfur recovery unit.

Where is this exhaust coming from, after the incinerator? Sulfur dioxide and returning sulfur for further hydrogenation in sulfur recovery? Could you explain it in detail? It would be great if there were some materials for everyone to study*study*.

Does the new idea proposed by the original poster have any practical results?

Dimethyl sulfoxide does not have good thermal stability; it generally decomposes at 120°C! It is not an ideal solvent for oil extraction

The exhaust gas burned after passing through the incinerator. This mainly involves corrosion issues. At present, Shell Consolf is widely used abroad, while in China it is only applied in thermal power flue gas systems. There is a company in China named Ion Liquid Desulfurization, which is mainly used for flue gas desulfurization in the non-ferrous metals industry; I haven’t heard of any applications for sulfur recovery with this technology.

Is sulfur dioxide used in the desulfurization recovery reactor? Are there any practical application examples for this process?

It’s not as simple as you think. We specialize in desulfurization using ionic liquids, and we have already built more than 10 such systems

Does your company carry out desulfurization using ionic liquids? The technology of that company?
