Under the Hood E-Mail Delivery and Retrieval When you have a choice, always use DNS for delivering your e-mail. When you use DNS, you are responsible for deciding where e-mail goes. The e-mail headers are correct and you re actually being a good Internet citizen. When you forward e-mail to what s called a smart host, the headers will show that the e-mail was forwarded or relayed, and in today s world when people are being swamped with spam, that alone is enough to get your e-mail blocked from many servers. E-mail is retrieved either directly from POP3 (Post Office Protocol 3) mailboxes and then routed to Exchange, or the e-mail is delivered directly to Exchange. POP3 mailboxes are the easiest to manage. They will have addresses such as user@YourISP.com. Many ISPs include 5 or 10 free POP3 e-mail accounts with their service. How your ISP handles incoming e-mail determines the configuration of email delivered directly to Exchange. Either it s delivered to Exchange as soon as received, or it s held until your server sends a signal to the ISP. Two types of signal are in use:

lower temperature process for sequestering carbon dioxide. Disposal of spent shale is also a problem that must be solved in economic fashion for the large-scale development of oil shale to proceed. Retorted shale contains carbon as char, representing more than half of the original carbon values in the shale. The char is potentially pyrophoric and can burn if dumped into the open air while hot. The heating process results in a solid that occupies more volume than the fresh shale because of the problems of packing random particles. A shale oil industry producing 100,000 bbl/day, about the minimum for a world-scale operation, would process more than 100,000 t of shale (density about 3 g/cc) and result in more than 35 m3 of spent shale; this is equivalent to a block more than 100 ft on a side (assuming some effort at packing to conserve volume). Unocal s 25,000 bbl/day project of the 1980s filled an entire canyon with spent shale over several years of operation. Part of the spent shale could be returned to the mined-out areas for remediation, and some can potentially be used as feed for cement kilns. In situ processes such as Shell s ICP avoid the spent shale disposal problems because the spent shale remains where it is created (Fletcher, 2005). In addition, ICP avoids carbon dioxide decomposition by operating at temperatures below about 350 C (662 F). On the other hand, the spent shale will contain uncollected liquids that can leach into groundwater, and vapors produced during retorting can potentially escape to the aquifer. Shell has gone to great efforts to design barrier methods for isolating its retorts to avoid these problems (Mut, 2005). Control of in situ operation is a challenge that Shell claims to have solved in its work (Mut, 2005; Karanikas et al., 2005). Shale (such as the Colorado shale) that contains a high proportion of dolomitic limestone (a mixture of calcium and magnesium carbonates) thermally deposes under the conditions of retorting and releases large volumes of carbon dioxide. This consumes energy and leads to the additional problem of sequestering the carbon dioxide to meet global climate change concerns. In addition, there are also issues with the produced shale oil that also need resolution. Shale oil is different to conventional crude oils, and several technologies have been developed to deal with this. The primary problems identified were arsenic, nitrogen, and the waxy nature of the crude. Nitrogen and wax problems were solved by Unocal and other companies using hydroprocessing approaches, essentially classical hydrocracking. Since that time, Chevron and ExxonMobil have developed technologies aimed at making high-quality lube stocks, which require that waxy materials be removed or isomerized. These technologies are well adapted for shale oils. However, the arsenic problem remains (DOE, 2004b). Unocal found that its shale oils contain several parts per million of arsenic. It developed a specialty hydrotreating catalyst and process, called for Shale Oil Arsenic Removal (SOAR). This process was demonstrated successfully in the 1980s and is now owned by UOP as part of the hydroprocessing package purchased from Unocal in the early 1990s. Unocal also patented other arsenic removal. Arsenic removed from the oil by hydrotreating remains on the catalyst, generating a material that is a carcinogen, an acute poison, and a chronic poison. The catalyst must be removed and replaced when its capacity to hold arsenic is reached. Unocal found that its disposal options were limited. Today, regulations require precautions to be taken when a reactor is opened to remove a catalyst. Thus several issues need to be resolved before an oil shale industry can be a viable option. These issues are not insurmountable but require the search for viable alternatives. For example, an alternative not much explored involves chemical treatment of shale to avoid the high-temperature process. The analogy with coal liquefaction here is striking: liquids can be generated from coal in two distinct ways: (a) by pyrolysis, creating a char coproduct, or (b) by dissolving the coal in a solvent in the presence of hydrogen.
