Mega methanol

Mega-Methanol This is a category of methanol-producing plant, not a particular process. Such plants have capacities of up to 10,000 tons per day. Engineering companies that have designed or built such plants include Lurgi and Davy. 

Commercial plants Thirty-five methanol plants have been built using Lurgi s low-pressure methanol technology. Two contracts for 5,000-mtpd plants using Lurgi s mega methanol technology have been awarded. 

Commercial plants Forty-nine methanol plants have been licensed applying Lurgi s Low-Pressure methanol technology. Six Mega Methanol licenses are in operation two are under construction and a MegaMe-thanol license has been awarded with capacities up to 6,750 metric tpd of methanol. 

MegaDME A process for making dimethyl ether from methanol. Developed by Lurgi, based on their Mega-Methanol process, but not yet commercialized. 

Science dealerships aren t the only places to get the stuff one needs. At those mega hardware stores one can find pure acetone, methanol, ethanol, toluene, methyl ethyl ketone, DCM(as a constituent of some stripping agents), sodium hydroxide in the form of lye, and some acids such as sulfuric and hydrochloric. These precious tools can be bought there cheaply and in great quantity. 

The second cleanup step uses a 5-g Varian Mega Bond Elut Cig SPE cartridge, preconditioned with 20 mL of methanol and 20 mL of 85% H3P04-water (1 50, v/v). Load the entire volume of the sample solution precleaned by the first SPE cartridge on to the second Cig SPE cartridge. Rinse all glassware used for collecting and...

Sample preparation for the determination of cyclamate by HPLC can be performed as described in Sec. I.C. (17,24,35,43). Potassium bromide can be used as an internal standard (17). In order to reduce interference, extracts can be clarified with Carrez reagents (24,35) or by solid-phase extraction. Nakazato et al. (43) added tetrabutylammonium bromide to the extract, adjusted pH to 4.0 -5.0, passed it through a Mega Bond Elut Cl 8 cartridge, and eluted cyclamate with a mixture of acetonitrile water (3 7, v/v). Lehr and Schmid (71) used an amino-anion-exchange column for the purification of cyclamate. After activation of the column with n-heptane, methanol, water, and 30% acetic acid, the sample was passed through the column and washed with water. Cyclamate was eluted with 2 M NaOH solution. 

Methanol is very important both as a produet and as a feedstock in chemical industry the total world capacity is currently over 30 Mt/a and is rising at about 3% p.a. Syngas is now the only realistic feedstock for making methanol. Major plants to make it from very cheap raw materials have been built in Trinidad, Saudi Arabia and elsewhere these use methane from oil wells, which was previously flared to waste, but can easily be converted into syngas. Such methanol plants use what is termed stranded gas which is natural gas in a remote area where it cannot be economically used for any other purpose. Very large mega-scale methanol plants > 1.5 Mt/a are now built. For example in Trinidad, which is now the world s largest exporter of methanol, with a total production capacity of 6.5 Mt/a.
