Demand-Surge

The retailer needed to restructure the supply chain to manage two channels of procurement. Placement of orders to the Honduran company was greatly simplified with advance orders of quantity Q and long lead times. To manage procurement from Griffin, on the other hand, the retailer needed to track demand D, per period of

As mentioned above, the first metathesis reaction studied was the equilibrium between propylene and an ethylene 2-butene mixture. In the initial Phillips process this was used to convert excess propylene into ethylene and 2-butene (Scheme 5.55). When propylene demands surged, the process was reversed and is now known as olefins conversion technology (OCT). The OCT process is operated with a fixed-bed reactor, W03 on silica serves as a catalyst. In order to allow... 

Usually, immediately upon entering the plant, supply water is split into potable water and process water. This is done by using an air break or back flow preventers. This is a precaution against process contaminants backing up into potable or city water and vice versa. Often a break tank is used as the air break since it also provides storage capacity for demand surges at the use points. 

Consider supply chains that face significant short-term changes events that require rapid adjustment and adaptation of flows. In a book titled Orchestrating Supply Chain Opportunities, Iyer and Zelikovsky [63] focus on the information system as one tool to manage events that include weather-related disruptions (like Hurricane Katrina), product failures that require rapid redesign (Uke the Kryptonite bicycle lock), demand surges (such as those faced by Amazon.com), among others. 

The actions of the Revolutionary government had allowed others to freely benefit from the discovery of Leblanc. In 1806, a Leblanc plant was opened by Payen at Dieuze, and others opened in Rouen and Lille. In 1810, the first Leblanc plants were operating in Marseilles, which became the heart of the French soda ash industry. By the end of the decade, total alkali production surpassed 10,000 tonnes per year in France. Sulfuric acid demand surged with it. In 1815, France was producing 20,000 tonnes per year of sulfuric acid. In 1822, a major Leblanc plant was opened in Chauny. Chemical production on this scale had never been seen before. 

Sulfuric acid demand surged ahead at astronomic rates, but no new plants in Europe were using elemental sulfur. All new plants were on pyrites, and the established facilities switched in the following decades. By 1880, the elemental sulfur market in Europe for the manufacture of sulfuric acid had disappeared The resilient demand for sulfur, though, was almost oblivious to these changes and continued to surge ahead. By the mid-1880 s, Sicilian exports had double in two decades to 350,000 tonnes. 

The War protected Europe from Frasch sulfur and global demand surged. Even so, this was a diffrcult year for the industry. Labor trouble and restrictions on fuel supply depressed production. In 1918, the term of COISS was renewed. After the war, the Sicilian industry was back on hard times. Trans-Atlantic vessel rates dropped, allowing the U.S. Frasch producers to be even more competitive in Europe. The two major markets, Britain and France, had switched mainly to American product. In 1921, the Italian government intervened to save the Mtering business, a feature that the Sicilian sulfur industry would henceforth be dependent upon to survive.
