Total productivity improvement

A renewed investment in Product and Process R D supports the theme of technical leadership. Also, Product and Process R D and Consulting support the technical leadership theme. Total Productivity Improvement addresses all the costs that go into installing a fastener, not just the cost of the fastener itself. Acme reckoned its technical position was unique in the industry. That capability would have value to customers needing new... 

This productivity improvement usually amounts to at least 10%-20% of total staff resources of a laboratory complex. The reader can verify this by assessing for his/her own labs the percent of staff activity spent manually recording data that could be captured automatically,... 

As the protective barrier between the body and the external environment, the skin is exposed to potentially damaging chemicals on a daily basis. It has been estimated that approximately 80,000 chemicals are in common use worldwide [5] and new products are being continuously introduced. Chemical production for most countries increased in 2004 with an increase in the total production index for all chemicals of 2.9% in the United States, 4.3% in the United Kingdom, and 6.8% in Canada [6], As new products are being developed and chemical production increases, toxicologists are faced with the need to develop improved methods for evaluating the potential of these chemicals to induce contact dermatitis. 

The benefits discussed earlier fall into two areas the time-value of information and the improvement in laboratory productivity. Assessing the benefits of the time-value of information requires examination of the total process through which that information will be used. For example, using data such as the turnaround time, rate at which material is produced, its value, and losses attributable to scrap or rework, one can estimate the savings. Similarly, knowing the average labor, overhead, and General and Administrative (G A) costs allows one to convert productivity improvements in the lab to dollar values of equivalent labor made free for more productive uses. 

The second largest use of sodium bicarbonate, accounting for approximately 25% of total production, is as an agricultural feed supplement. In cattle it helps maintain rumen pH and aids fiber digestibility for poultry it helps maintain electrolyte balance by providing sodium in the diet, helps fowl tolerate heat, and improves eggshell quality. 

The aluminum so produced sold for 158 per pound owing to the high cost of potassium and to the expense involved in obtaining dry aluminum chloride. Substitution of the cheaper metal sodium for the potassium lowered the price of aluminum to around 25 per pound, and subsequent improvements in methods for the production of sodium made possible the sale of aluminum at 5 per pound. Even so, these improved methods resulted in a total production of less than 100 lb of aluminum during the years in which these methods were used. 

Solvent-resistant nanofiltration and pervaporation are undoubtedly the membrane processes needed for a totally new approach in the chemical process industry, the pharmaceutical industry and similar industrial activities. This is generally referred to as process intensification and should allow energy savings, safer production, improved cost efficiency, and allow new separations to be carried out. 

Installations The Dow Chemical Co. (Dow), developed their ion exchange resin based BPA technology in the late 1960 s. Dow has continued to improve the technology, especially in the areas of product quality, higher operating efficiency and reduced capital cost. Dow has a total production capacity exceeding 300,000 mty in four plants located in Texas and Stade, Germany. 

Economics Variable production cost is dominated by feedstock pricing, especially for natural gas. The installed plant cost is the other main contributor to the total product cost. Total energy usage for a self-contained plant is typically around 7.8 Gcal/ton of methanol (31 MMBtu/ton) on an LHV basis. Capital investment varies tremendously with size and location however, a guideline installed cost for a 3,000-tpd plant is approximately U.S. 250-300 million. Synetix s LCM process offers improved economics over conventional processes. It is ideal for large capacities (over 3,000 tpd) where conventional plants cannot be used, such as, offshore production. 

Compared to its use in product manufacturing, the use of formaldehyde in the medical fields is relatively small. Consumption in this area averages approximately 1.5% of the total production volume (WHO 1989). Some of the earlier, minor, medicinal applications for formaldehyde included its use during vasectomies, as a foot antiperspirant or as a preservative in such products, as a treatment for athlete s foot, and as a sterilant for echinococcus cysts prior to their surgical removal (lARC 1982). In veterinary medicine, formaldehyde has been used therapeutically as an antiseptic and as a fumigant. It has also been used to treat tympany, diarrhea, mastitis, pneumonia, and internal bleeding in animals (Windholz et al. 1983). In animal nutrition, formaldehyde is used to protect dietary protein in ruminants. It is used as a food additive to improve the handling characteristics of animal fat and oilseed cattle food mixtures (WHO 1989). 

A common trend seen today in this industry is plant integration through the merger and alliance of refractories companies. In general, the global refractory production has increased, due in part to process optimization (better usage of refractories) or to improved refractory materials with better performance. Monolithic refractories consumption, however, has markedly increased and represents today a large portion of the total. For instance, it is about 60% of the total production in Japan [63],...
