Abstract
The membrane process concept coupled with phase inversion technique has been successfully applied for the first time for the preparation of ionic liquid (IL) encapsulated microspheres using polyetheretherketone with card group (PEEKWC), trihexyl(tetradecyl)phosphonium chloride[CYPHOS IL 101] in N,Ndimethylformamide (DMF) as dispersing phase and dodecane, ethanol and water as continuous phases. The technique yields porous, spongy, spheres with smooth surface and diameter around 1000 lm, with morphology and chemical composition strongly affected by preparative conditions. IL loading capacity and subsequent surface topography has been investigated using optical microscopy, FT-IR, SEM, EDX, TGA and SDT.

Abstract
A series [C3Omim][X] of imidazolium cation-based ILs, with ether functional group on the alkyl side-chain were synthesized and structure of the materials were confirmed by various techniques like 1H, 13C NMR spectroscopy, MS-ESI, FTIR spectroscopy and EA. More specifically, the influence of changing the anion with same cation is carried out. The absorption capacity of CO2 for ILs were evaluated at 30 and 50 ºC at ambient pressure (0-1.6 bar). Ether functionalized ILs shows significantly high absorption capacity for CO2. In general, the CO2 absorption capacity of ILs increased with a rise in pressure and decreased when temperature was raised. The obtained results showed that absorption capacity reached about 0.9 mol CO2 per mol of IL at 30 ºC. The most probable mechanism of interaction of CO2 with ILs were investigated using FTIR spectroscopy, 13C NMR spectroscopy and result shows that the absorption of CO2 in ether functionalized ILs is a chemical process. The CO2 absorption results and detailed study indicates the predominance of 1:1 mechanism, where the CO2 reacts with one IL to form a carbamic acid. The CO2 absorption capacity of ILs for different anions follows the trend: BF4 < DCA < PF6 < TfO < Tf2N. Moreover, the as-synthesized ILs is selective, thermally stable, long life operational and can be recycled at a temperature of 70 ºC or under vacuum and can be used repeatedly.

Intelligent Googling

“I was so naive as a kid I used to sneak behind the barn and do nothing.” -- Johnny Carson (American TV Host, 1925-2005)

The September 2012 edition of Hydrocarbon Engineering (HE) magazine has a couple of articles on heavy crude that look interesting.  Unfortunately, if you do not subscribe to the magazine, you will not be able to read the articles.  They appear nowhere else online.

However, by intelligent Googling you can sneak a peek at the likely content of the articles.

Follow MAN Diesel & Turbo


“Right or wrong, the customer is always right.” -- Marshall Field (American department-store owner 1834-1906)

TIP: Follow MAN & Turbo's DieselFacts

DieselFacts is MAN Diesel & Turbo's technical customer magazine. DieselFacts online contains current and previous editions with extra material, including video clips.
http://mandieselturbo.com/0000665/Press/Publications/DieselFacts.html

[ SAMPLE ARTICLE EXCERPT ]
DieselFacts 2/2012
Tier III Selective Catalytic Reduction
Development of large two-stroke diesel engines
[ EXCERPT ]
With a view to meeting the NOx Tier III regulations due to take effect in 2016, Hitachi Zosen is developing an SCR (Selective Catalytic Reduction) system for low-speed diesel engines in cooperation with MAN Diesel & Turbo. To this end, a prototype was recently fitted to an MAN B&W 6S46MC-C engine aboard a general cargo newbuilding for Nissho Shipping.
NOx
regulation
The regulation of air pollution stemming directly from diesel engines is among the IMO regulations covering hazardous waste from ships. The first NOx regulation was introduced in 2000 (Tier I), with Tier II coming into force in 2011 and Tier III in 2016. As such, Tier III represents an 80% reduction in NOx compared with Tier I. While it was possible to meet Tier II limits through engine adjustments alone, meeting Tier III makes it necessary to introduce external techniques. It is mandatory to observe the new NOx regulations, and any negative effect on fuel consumption and running costs is a major concern for ship operators.
De-NOx technology for Tier III
Realistically, SCR and EGR (Exhaust Gas Recirculation) are the two main techniques that can help engines meet Tier III NOx regulations, based on the service experience from power plants and cars, respectively.
Hitachi Zosen and MAN Diesel & Turbo agreed to develop an SCR system for two-stroke engines located before the turbocharger. Hitachi Zosen chose SCR as its NOx-reduction method because: it is possible to make a compact system using high-temperature and high-pressure gas, and de-NOx efficiency is improved
it is possible to maintain the engine’s running performance whether the SCR system is running or not and with no harm to the engine Hitachi Zosen is a total solution provider of marine SCR systems.
SCR system for marine diesel engines
There are two solutions for a marine SCR system. One is a lowpressure system, installed downstream of the turbocharger. The other is a high-pressure system, installed upstream of the turbocharger and which Hitachi Zosen has concentrated on.
High-pressure SCR system
A diesel engine emits nitrogen oxides and dioxides. When a urea solution is injected into the duct upstream of the reactor, it is then converted into ammonia. Subsequently, NOx reacts with the ammonia in the catalyst in the HPSCR reactor and is converted into nitrogen and water with the clean gas then flowing into the turbocharger. Hitachi Zosen provides the optimised control system of urea solution injection.
Two SCR on/off valves and an SCR bypass valve control the smooth flow of flue gas into the SCR system, using a sequence that is programmed by MAN Diesel & Turbo.
NOx
removal catalyst
The Hitachi Zosen catalyst has a characteristic triangular configuration and its wall also has a lot of fibre matrix reinforcement. It is therefore very tough and resistant to engine vibration despite being quite thin.

Drill Down, Baby, Drill Down …


“The key to being a good manager is keeping the people who hate me away from those who are still undecided.” -- Casey Stengel (American Baseball Player and Manager, 1891-1975)

Managers love to talk about “drilling down” into the data.  Here’s an example of applying that concept to Google® Scholar.

Pretend that we want to know what technologies Exxonmobil has been pursuing.  Entering the simple search string Exxonmobil yields around 44,000 hits.

But we are primarily interested in recent Exxonmobil activity.  We drill down by clicking the Advanced Scholar Search button.



A search form pops up which allows us to restrict the search to items no older than 2011.



The result is a list with around 6,000 results.  But we want to focus on Exxonmobil’s recent desulfurization activities.  So we drill down further.

Back at the Advanced Scholar Search form, we add the following key words …

Sulfur desulfurization biodesulfurization electrodesulfurization



Now we’re down to about 1,000 on the hit list.  We are cooking, as my grandmother used to say, with gas.

Drill down, baby!

Another Reason to Use Delicious


“After all these years I see that I was mistaken about Eve in the beginning; it is better to live outside the Garden with her than inside it without her.” -- Mark Twain (American Humorist, Writer and Lecturer. 1835-1910)

I recently changed computers and was sure that I had thought of everything I had to save from my old computer to transfer to the new one.

I was mistaken.  I forgot to save my bookmarks.

Fortunately, I had added the bookmarks to my Delicious (www.delicious.com) social bookmarking account.  All I had to do was to export the bookmarks from Delicious, then import them to my new computer via my browser.

TIP: to export links from Delicious …
Log in and head to your "Settings" page, found by mousing over the "Profile" button on the top right of Delicious. There you'll find options to both import and export your links or browser bookmarks.






Bonus TIP: Visit my Delicious desulfurization bookmarks.
The easiest way to do so is to visit www.delicious.com and search for desulfurization.

It is difficult to remove refractory sulfur compounds such as benzothiophene (BT), dibenzothiophene (DBT) and its derivatives by means of conventional hydrodesulfurization (HDS) process. Severe operating conditions including high temperature, high pressure, highly-active catalysts and high hydrogen consumption, are required to achieve deep desulfurization of gasoline. Alternative desulfurization processes, such as extractive desulfurization, selective adsorption desulfurization, biodesulfurization, and oxidative desulfurization, have been attracting the attention of a growing number of researchers.
