WEIXIAN Unit 79 Neutralization and Dioxane Stripping When producing SLES, the sulfate needs to be neutralized with pure water, caustic soda, H2O2, and buffer in the neutralization reactor, all materials react by high-speed mixing, then remove dioxane together with air in the stripping tower under vacuum condition, meanwhile, the cooling procedure is also done in this tower.   Features: Compared with Italy's vacuum neutralization, WEIXIAN stripping tower is a static equipment, without motor and maintenance requirement. Before going into the stripping tower, products react in the micro positive pressure reactor, so there is no acid gas corrosion happened in condensate and vacuum pump. Meanwhile this unit has a 10 times SLES recycle loop, comparing to similar technologies of other suppliers, this process makes the neutralization temperature rise less than 5℃, which helps us to get the products with lighter color, more stable pH value and lower dioxane content. This unit is able to realize ultra-low dioxane content.

Acetylene (C2H2) is a highly unstable gaseous hydrocarbon. Stored in compressed cylinders, it is dissolved in acetone (C3H6O) as the solvent. Interestingly, this unique cylinder utilizes calcium silicate, a porous medium, to adsorb acetylene, preventing decomposition reactions.

IOTA-2211 is a methyl-terminated oligomer, a colorless or light yellow transparent liquid, and belongs to modified fluorosilicone oil. Due to the introduction of trifluoropropyl groups, it has oil resistance, solvent resistance, low surface tension, and low refractive index. At the same time, the introduction of silicon-hydrogen segments as active groups can react with double bonds, hydroxyl groups, and other groups. #fluorosiliconeoil #fluorosilicone #Modifiedsiliconeoil #Functionalsiliconeoil

🔬 Determination of Fluorine in Coal Sample⚡️ Coal naturally contains fluorine, chlorine, and sulfur compounds. When burned, these release harmful acids like hydrofluoric acid, which can damage equipment in power plants. To prevent this, power plants need low-fluorine coal. Discover how Metrohm Combustion IC helps determine fluorine content in coal using ion chromatography. 📚 Learn more in our latest application note: https://brnw.ch/21wPAL1 #Metrohm #IonChromatography #CoalAnalysis #PowerPlants #Fluorine #CombustionIC #CIC

..........From chaos to order? Analyzing a #mineral #oil inhibited after the RPVOT test, then processed in extreme conditions (presence of water, catalyst, high pressure oxygen and high temperature), as well as noticing a change in its appearance and properties, such as #acidity, #viscosity, #density, #color, etc., It is noted that the composition of the carbon constituting the oil changes, there is an increase in aromatic carbon at the expense of paraffinic carbon, The chaos that is generated through oxidation reactions leads to the formation of intermediates reactive substances that can undergo cycloalkylation processes with the transformation of more thermodynamically stable benzene rings under extreme conditions, but also dehydrogenation, catalytic cracking (although not predominant as the % of paraffinic carbon does not vary much), or condensation and polymerization reactions can contribute to the formation of the aromatic fraction, The question mark refers to the fact that a naphthenic fraction consisting of 6 carbon atoms such as cyclohexane, by direct dehydrogenation (due to the stress mentioned above) could generate benzene, maintaining its annular structure, a more plausible and less complex solution.......(corrected slide)

#SulfideScaleInhibitor Metallic Sulphur Dissolver-Solution for metallic sulfide scales in oil and gas gathering and transportation. We would like to recommend a product: Sulfide Scale Remover UBPro-443,a kind of organic phosphates-based scale dissolver. UBPro-443 truly inhibits sulfide scale formation at much lower dose rates and controls the Iron Sulfide and other sulfide scales. In addition, this product can dramatically increase the running days of wells. more: https://lnkd.in/g3PJZFpp

Aluminum Fluoride (ALF3) Aluminum fluoride, alias aluminum trifluoride, is an inorganic compound with chemical formula AIF3, which is prepared by the reaction of aluminum hydroxide or metallic aluminum with hydrogen fluoride, or by the reaction of aluminum trichloride with hydrofluoric acid and ammonia water.  https://lnkd.in/gCQF9ZAE

In a converter (such as in the contact process for producing sulfuric acid), sulfur dioxide (SO₂) is oxidized to sulfur trioxide (SO₃) using a catalyst, typically vanadium(V) oxide (V₂O₅). This reaction takes place in the converter at high temperatures (around 450-600°C) and is described by the following chemical equation: \[ 2SO_2 + O_2 \rightarrow 2SO_3 \] Key points about the process: - **Exothermic Reaction**: The conversion of SO₂ to SO₃ is exothermic, meaning it releases heat. - **Catalyst**: V₂O₅ is used to increase the reaction rate without being consumed. - **Equilibrium**: This reaction is reversible, and high temperatures and pressures are often used to shift the equilibrium toward producing more SO₃. The sulfur trioxide produced is then absorbed in water to form sulfuric acid (H₂SO₄), completing the process.
