ETHYLENE PRODUCTION CHEMICALS. Hydrogen sulfide is a naturally occurring gas in many crude oils. It can also form during the refining process if sulfur-containing compounds in crude oils degrade at high temperatures. Refiners face significant safety, environmental, operational and compliance issues when hydrogen sulfide contamination occurs.
Approximately 90% are produced during the process of extracting phosphate from phosphoric ore. Approximately 5% come from the production of hydrogen fluoride or sodium fluoride. Approximately 5% come from the purification of high-quality quartz. Since the early 1950s, FSA has been the main additive used for water fluoridation in the United States.
Pyrolysis. Pyrolysis is one of the technologies available to convert biomass to an intermediate liquid product that can be refined to drop-in hydrocarbon biofuels, oxygenated fuel additives and petrochemical replacements. Pyrolysis is the heating of an organic material, such as biomass, in the absence of oxygen.
well as other natural chemical constituents, such as heavy metals and dissolved solids from the geological formation and synthetic chemicals that are added during the production process to prevent equipment corrosion and bacterial growth and for a myriad of other purposes (Fakhru'l-Razi et al., 2009).
Chemical additives (flocculants) are added to assist the sedimentation process. The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process).
The hardening process occurs through the hydration of calcium sulfate hemihydrate (stucco) to the dihydrate form (gypsum) ... The stucco is stored for the production of wallboard ... effects of chemical additives that are commonly used
Chemical additives can improve the performance of abrasion resistance, hydrolysis resistance, flame retardation, lightfastness, and cleanability. Polyurethane Coated Fabric Manufacturing Process.

Other chemicals can be used to fight diseases in farm animals or crops, or can sometimes be found in food as a result of a production process such as heating/cooking or decontamination treatment. Some plants and fungi naturally produce toxins that can contaminate crops and be a concern for human and animal health.
Chemical Additives. The term "chemical additive" means a chemical product (including products of disassociation and degradation, collectively "products") introduced into a waste stream that is used for cleaning, disinfecting, or maintenance and which may be detected in effluent discharged to waters of the Commonwealth.
process to extract the alkali-soluble form of lig-nin. Pulp is washed with water in the bleaching process. In modern mills, oxygen is normally used in the first stage of bleaching. The trend is to avoid the use of any kind of chlorine chemicals and employ "total chlorine-free" (TCF) bleaching. TCF processes allow the bleaching effluents to
Chemical processes such as chemical reactions operate in chemical plants to form new substances in various types of reaction vessels. In many cases the reactions take place in special corrosion-resistant equipment at elevated temperatures and pressures with the use of …
Polymers contribute substantially to this positive balance of trade in chemicals. For example, plastics in both primary and nonprimary forms contributed $6.0B, or 37 percent, to the net positive trade balance in chemicals during 1992 (Chemical & Engineering News, 1993). Plastics manufacturing is an important part of the national economy.

In the case of the chemical industry, the committee focused its examination of environmental metrics on the production of commodity and specialty chemicals and polymers. Excluded in the analysis are high-value materials such as cosmetics, food additives, and health care products, including pharmaceuticals, which account for a significant ...
Chemical industry, complex of processes, operations, and organizations engaged in the manufacture of chemicals and their derivatives. Raw materials include fossil fuels and inorganic chemicals. An average chemical product is passed from factory to factory several times before it emerges into the market.
Chemical food additives preserve shelf life by reducing or eliminating the growth of microorganisms that cause food decay. These added chemicals are controversial as some may have a detrimental effect on your health. Eating more fresh, whole foods may be a safe alternative to avoiding these chemical additives used in food processing.
Sulfur is a key component in tire manufacturing. Tires are made out of a product known as vulcanized rubber. The vulcanization process is what makes the tires hard and heat resistant. This works partly because of the mixture of sulfur into the rubber. This is one of the chemicals present in most types of tires, while others are only used when ...

Food Additives: To increase shelf life and to make food attractive various chemicals are added to food. Main categories of food additives are food colours, flavours and sweeteners, antioxidants, fat emulsifiers, stabilizing agents, flour improvers, food preservatives, and nutritional supplements like minerals, vitamins, and amino acids.
However, these chemicals are key to the efficient production of food (Figure 2). Figure 2 Sales value of crop protection chemicals worldwide by type of crop (2008). Sometimes mimicking nature's own way of protecting plants can provide the answer to cost-efficient synthesis of effective crop protection chemicals.
The migration process can be divided into four major steps exemplified for a food contact material: 1) diffusion of chemical compounds through the polymers, 2) desorption of the molecules from the polymer surface, 3) sorption of the compounds at the plastic–food interface, and 4) absorption of the compounds in the food . The mass diffusion ...
