Chemical Industry Products and Processes from DuPont Clean Technologies
Comprehensive Solutions for Air Pollution and Energy Control in the Chemical Industry
Since the chemical industry is process oriented, utilizing rotating equipment, chemical resistant piping, pressure vessels, instrumentation, other specialty hardware items and energy sources, the issues related to generating and controlling air pollution and conserving and/or recovering spent energy are diverse. Our portfolio of technologies and processes can provide innovative solutions and process enhancements for the individual issues our customers in the chemical industry face. MECS® products also solve some of the world’s most difficult mist and particular removal problems. The tougher the application, the more likely one of our products can be custom-designed to meet each individual customer’s needs.
SPENT SULFURIC ACID REGENERATION
Industrial producers are increasingly faced with difficult choices about how to treat harmful waste streams that are byproducts of their core processes. In established industries with high volumes, toll sulfuric acid regeneration facilities are an attractive alternative to on-site neutralization or disposal. But there are many industrial processes from which sulfur-bearing waste streams have historically been neutralized instead of regenerated.
Neutralization minimizes the up-front capital investment at the expense of operation costs of the neutralization reagent and disposal. And while reagents remain readily available around the world, some governments are increasing regulatory standards for waste disposal, making the regeneration of spent acid streams more attractive than in the past. The most proven way to regenerate spent sulfuric acid is to decompose the feeds into their most basic components so that they can be cleaned and recombined to form the desired product stream. DuPont Clean Technologies offers best-in-class, proven systems to reliable regenerate sulfuric acid and upgrade waste streams into valuable products.
OUR INNOVATIVE SOLUTIONS
Producers of organic chemicals trust MECS® technologies, products and processes to add value and environmental compliance to their operations. In many cases Brink® mist eliminators are an excellent solution to remove harmful impurities from off-gas streams.
PLASTICS & RESINS
Organic emissions in the plastics and resins industry are challenges that are met with our technologies. Plasticizer vapors produced during the manufacture of plastics and resin products can condense in the air causing hydrocarbon emissions and dense plumes, unless they are captured. Brink® mist eliminators in packaged systems can be used on curing ovens, extruders and injection molding machines to effectively remove the sub-micron mists generated in these processes
Many opportunities exist for energy savings in this industry and we can custom design solutions for individual plant needs to ensure process optimization. As methanol production affords many opportunities for energy savings, MECS®-ThermoZTM gas-to-gas heat exchangers can be used in conjunction with reformers to provide an excellent means of recovering heat that would otherwise be lost to ambient surroundings.
MECS® Sulfuric acid and environmental technologies provide customized solutions to a variety of industrial segments. DuPont Clean Technologies offer a large range of products and services for the Sulfuric industry.
