Ammonium Polysulfide provides a needed tool for the refinery. As refineries are being driven to lower quality crudes, problems associated with nitrogen are on the increase. A major problem is the generation of cyanide in the various thermal cracking units, primarily the catalytic cracking and coking processes.
Ammonium Polysulfide is used to chemically scavenge free cyanide which is generated in thermal cracking processes (fluidized catalytic cracking units, hydrocrackers, delayed cokers, fluidized cokers, etc.) in refineries, converting it to thiocyanide, which is easily handled in the refineries' water treatment facility. If the free cyanides are not scavenged, they can contribute to corrosion within the units, downstream units, and/or send the free cyanide to the refinery's wastewater plant.
Ammonium Bisulfite is a very versatile product and is used in many process applications in a wide range of industries for continuous cyanide removal from industrial waste effluents. Successfully used by mines as a liquid alternative to SO 2 gas in Inco's SO 2 /Air process, providing similar performance with the safety of a water-based material. Ammonium Bisulfite used in a wide range of applications, including:
• Oxygen scavenging
• Sugar beet processing
• Caramel coloring
• De-chlorination
• Cyanide reduction in precious-metals mining process
• Oxidation inhibitor
Ammonium Sulfide may be used in the copper processing circuit to separate copper from other ores such as molybdenum. Ammonium Sulfide may be used by itself or in conjunction with NaHS (sodium hydrosulfide) in this process.
Ammonium Sulfide is a slightly alkaline liquid with a typical pH of approximately 9.5. The liquid form is typically green to reddish-yellow in color and has a strong hydrogen sulfide (rotten egg) odor. Ammonium sulfide is considered stable in normal transportation. Ammonium Sulfide are typically 45% concentration by weight and weigh approximately 8.33 pounds per U.S. gallon (1.0 gm/cc).
Polymerized Polyol - is the variance of the graft copolymer of styrene with polyether, which is made of the technological process «in situ», that is, by the polymerization solution in the presence of another polymer solution. The use of additives in the formulation of the system to get the foam in an amount of 10-20% cannot change the process to significantly improve the physical and mechanical properties of the finished product PPU: increases carrying capacity and resilience foam technology to improve its processing, increases the durability and appearance of the finished products.
Methanol, also known as methyl alcohol, carbinol, wood alcohol, wood naphtha or wood spirits, is a chemical compound with chemical formula CH3OH (often abbreviated MeOH). It is the simplest alcohol, and is a light, volatile, colorless, flammable, poisonous liquid with a distinctive odor that is somewhat milder and sweeter than ethanol (ethyl alcohol). At room temperature it is a polar liquid and is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol. It is also used for producing biodiesel via transesterification reaction.
Methanol is produced naturally in the anaerobic metabolism of many varieties of bacteria. As a result, there is a small fraction of methanol vapor in the atmosphere. Over the course of several days, atmospheric methanol is oxidized by oxygen with the help of sunlight to carbon dioxide and water. A methanol flame is almost colorless, causing an additional safety hazard around open methanol flames.
Because of its poisonous properties, methanol is frequently used as a denaturant additive for ethanol manufactured for industrial uses— this addition of a poison economically exempts industrial ethanol from the rather significant 'liquor' taxes that would otherwise be levied as it is the essence of all potable alcoholic beverages. Methanol is often called wood alcohol because it was once produced chiefly as a byproduct of the destructive distillation of wood. It is now produced synthetically by a multi-step process: natural gas and steam are reformed in a furnace to produce hydrogen and carbon monoxide; then, hydrogen and carbon monoxide gases react under pressure in the presence of a catalyst.
An entire methanol economy, based on methanol as a primary energy-storage medium and fuel, has been seriously proposed.
Ethanol, also called ethyl alcohol, grain alcohol, or drinking alcohol, is a flammable, colorless, chemical compound. It is best known as the type of alcohol found in alcoholic beverages and in thermometers. In common usage, it is often referred to simply as alcohol.
Except for the use of fire, the fermentation of sugar into ethanol is very likely the earliest organic reaction known to humanity, and the intoxicating effects of ethanol consumption have been known since ancient times. In modern times, ethanol intended for industrial use is also produced from byproducts of petroleum refining.
Ethanol has widespread use as a solvent of substances intended for human contact or consumption, including scents, flavorings, colorings, and medicines. In chemistry, it is both an essential solvent and a feedstock for the synthesis of other products. It has a long history as a fuel for heat and light and also as a fuel for internal combustion engines.
Urea or Carbamide is an organic compound with the chemical formula CO(NH2)2. The molecule has two —NH2 groups joined by a carbonyl (C=O) functional group.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is solid, colorless, and odorless (although the ammonia that it gives off in the presence of water, including water vapor in the air, has a strong odor). It is highly soluble in water and practically non-toxic (LD50 is 15 g/kg for rat). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, the most notable one being nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry. The synthesis of this organic compound by Friedrich Wöhler in 1828 from an inorganic precursor was an important milestone in the development of organic chemistry, as it showed for the first time that a molecule found in living organisms could be synthesized in the lab without biological starting materials (thus contradicting a theory widely prevalent at one time, called vitalism).
The terms urea and carbamide are also used for a class of chemical compounds sharing the same functional group RR'N—CO—NRR', namely a carbonyl group attached to two organic amine residues. Examples include carbamide peroxide, allantoin, and hydantoin. Ureas are closely related to biurets and related in structure to amides, carbamates, carbodiimides, and thiocarbamides.
GLYCERIN (or Glycerine, Glycerol) is a simple Polyol compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides. Glycerol is sweet-tasting and of low toxicity.
CRUDE GLYCERIN. Crude glycerin contains a significant amount of methanol, water, soaps, and salts and typically has a glycerol content of anywhere between 40 to 88%. Crude glycerol is a natural by-product produced during the biodiesel production process, specifically taking place during transesterification.
TECHNICAL GRADE GLYCERIN. Technical grade glycerin is a refined, high-purity product that is water white with most of its contaminants completely removed. Technical grade glycerin contains no methanol, soaps, salts, and other foreign matter. Biodiesel plants purchased from SRS Engineering, unlike many of our competitor's plants, produce technical grade glycerin right from the start.
USP GRADE GLYCERIN. USP Grade Glycerin is a pharmaceutical grade glycerin suitable for food, personal care, cosmetics, pharmaceuticals, and other specialty applications. All of these products have met the US Pharmacopeia specifications (USP 30).
