Quality improvements, chemical industry

QRA practitioners can use to satisfy some QRA objectives. Also, the American Institute of Chemical Engineers (AIChE) has sponsored a project to expand and improve the quality of component failure data for chemical industry use. And many process facilities have considerable equipment operating experience in maintenance files, operating logs, and the minds of operators and maintenance personnel. These data can be collected and combined with industrywide data to help achieve reasonable QRA objectives. However, care must be exercised to select data most representative of your specific system from the wide range available from various sources. Even data from your own plant may have to be modified (sometimes by a factor of 10 or more) to reflect your plant s current operating environment and maintenance practices. 

Lead and Alloys Chemical leads of 99.9 percent purity are used primarily in the chemical industry in environments that form thin, insoluble, and self-repairable protective films, e.g., salts such as sulfates, carbonates, or phosphates. More soluble films such as nitrates, acetates, or chlorides offer little protection. Alloys of antimony, tin, and arsenic offer limited improvement in mechanical properties, but the usefulness of lead is limited primarily because of its poor structural qualities. It has a low melting point and tensile stress as low as 1 MPa (145 Ibf/in ). 

Operational. In addition to having a strong culture and awareness of security within an organization, an active and effective security program makes security part of operational activities, from daily operations (such as monitoring physical access controls) to scheduled annual reassessments. Chemical industries will often find that by implementing security into operations they can also reap cost benefits and improve the quality or reliability of the chemical service. 

Many facilities already measure the above parameters (and many others) on a regular basis to control plant operations and confirm chemical mixture quality more closely monitoring these parameters may create operational benefits for facilities that extend far beyond security, such as reducing operating costs and chemical usage. Chemical industrial facilities also should thoughtfully monitor customer complaints and improve connections with local public health networks to detect public health anomalies. Customer complaints and public health anomalies are important ways to detect potential contamination problems and other environmental quality concerns. 

Crosslinked PE foam is widely used today in the automotive, sport, leisure and packaging industries. The role of azodicarbonic acid diamide (ADC) in its manufacture is illustrated, showing possibilities of improving the production quality of chemically crosslinked PE foams by adding a modified azodicarbonic acid diamide. 

Food and feed additives, also known as dietary supplements, are minor ingredients added to improve the product quality. Most commonly, the effects desired relate to color, flavor, nutritive value, taste, or stability in storage. The market sizes are estimated to be 20 billion each for food and for feed additives, respectively. The major customers for the food additives are the big food companies Ajinomoto, Danone, Kraft, and Nestle, mentioned at the beginning of the chapter. With the exception of Ajinomoto, these companies are rarely backward-integrated. As they prefer to use natural ingredients rather than synthetic ones, they are not very important customers of the fine-chemical industry. Premixers, that is, enterprises that prepare ready-to-use mixtures of nutrients for the farmers who raise cattle, pigs, and chicken, are the main users of feed additives. 

An important lesson learned from the implementation of the project "Promotion and implementation of closing-the-loops cooperation and business models in the chemical industry" is the need for quality assurance of Chemical Leasing business models. The models must result in improved environmental performance of the participating companies, reduced risks of chemicals and enhanced human health protection. 

Currently, DSM uses biocatalysis, biotransformation, and fermentation technologies in addition to chemical methods to produce these specialties. To keep ahead of the competition and provide the best service to our customers, we use classical and/or advanced (gen)omics tools such as proteomics and metabolomics to make continuous improvements in the productivity and quality of our industrial workhorses. In the many cases where it is difficult - or impossible - to apply fermentation, we use (multi-step) biocatalysis to achieve our goal. Other in-house competences that are of growing relevance to the pharmaceutical area include the formu-... 

Amino acids are monomeric units of polypeptides and proteins. They are widely used in the food and chemical industries as flavor enhancers, seasonings and sweeteners e.g. for the improvement of bread quality, also in the production of drugs, cosmetics, synthetic leather and surfactants, in medicine for infusions and as therapeutic agents. Amino acids are produced by chemical synthesis or extraction from protein hydrolyzate. They may be also produced by microbiological methods. 

So economic forces within the chemical industry are compelling improved capital productivity. Requirements for on-aim product quality control grow increasingly tighter. More energy integration occurs. Im-... 

In this symposium both the chemical and propulsion companies are heavily represented, but this was not always true. Increased government support of propulsion research since 1958 necessitated the involvement of major segments of the chemical industry. Before this time, most propulsion research was conducted by propulsion companies as an essential aspect of product improvement and competitive marketing. The competition, in the more basic research areas, between propellant chemists and industrial chemists working on propellant ingredients has tended to improve the quality of both. 

Discussion confirmed that the perception of the ATP as corporate welfare is dead, and the debate is now a healthy one about process improvement and funding and growth levels. Although the ATP does not directly receive a funding stream from successful projects, the payback is real in terms of jobs, economic growth, and quality of life. The audience again commented on the chemical industry s historic aversion to collaboration and speculated on the reasons for it. 

The modern chemical industry has produced many important products that have improved health, the quality of life, and our prospects for more sustainable forms of development. However, the number of chemicals produced in great volumes and the number of products that contain these chemicals have brought serious concerns about the consequences of toxic substances on public health and ecosystems. These concerns, and others (see Box 3.1), boil down to a mistrust of the industry as a whole. Addressing this mistrust remains one of the major challenges facing the chemical industry (Moffet et al., 1999). 

DuPont became an early adopter of the six sigma philosophy. Many other companies in the chemical industry have followed. The following groups are also actively promoting lean six sigma the National Institute for Science and Technology (NIST), the American Society for Quality, and a number of trade associations. It is very likely that the use of these business improvement methods will continue to expand in the future. 

Many companies, both within the chemical industry and in other sectors, have recognized benefits from involving their suppliers and customers in various aspects of their business. The area of supply chain management (SCM) has become a critical element in the overall business strategy of improved productivity, reduced costs, and better control of the quality and potential risks associated with raw materials and intermediates. Proactive management of supplier environmental performance, as practiced by Hewlett Packard, can lead to product and process simplification, improved resource efficiency, product quality enhancement, reduced liability, and customer perception of the company as an industry leader.
