The reactor product stream is fed to the EO absorber for lights removal by water quenching. MEG(Catalytic MEG process) Technology MEG (Mono Ethylene Glycol) (Application) MEG is a vital ingredient for polyester fibers, film and PET packaging – all of which are seeing burgeoning demand. The process overview illustrates the urea plant process design. Global Mono-Ethylene Glycol Capacity by Process. MEG is injected at the inlets of the gas-to-gas exchangers and the propane chiller. The Global Mono-ethylene production capacity was 34.8 million tons in 2016. Certain articles contain the author's personal recommendations only. the solution is pumped through preheaters (hot recycle water and steam ) In the described process, MEG is produced via EO, which is manufactured in an integrated plant utilizing Shell EO technology. A flow diagram of the manufacture of ethylene glycol through the un-catalyzed hydrolysis of ethylene Oxide (Arrieta, 2001) is shown in Figure 1. © 2021 Access Intelligence, LLC. Part of this gaseous overhead stream is recycled to the reactor, while the other part is sent to a carbon-dioxide-removal unit composed of an absorber and a stripper. AIR None 15 REGULATORY INFORMATION LABELLING Harmful CONTAINS ETHANEDIOL RISK PHRASES R22 Harmful if swallowed. ROAD None ADR CLASS NO. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. The dehydration by liquid media is more famous and economic than solid media. A diluted EO stream removed from the absorber is fed to the EO stripper, where it is concentrated and recovered in the overheads. It is also used in antifreeze applications and in pharmaceuticals and cosmetics. The catalyst is separated and recycled to the ethylene carbonate reactors. Ethylene oxide production. 2.1.

Figure 1 depicts MEG production from ethylene via a process similar to the OMEGA catalytic process from Shell Global Solutions (The Hague, the Netherlands; www.shell.com). Monoethylene Glycol, MEG) is an organic compound, more specifically a diol (a chemical compound that contains two hydroxyl groups). The plant is to produce a total amount of 100,000 metric ton ethylene glycol per annum. The modern ethylene oxide/ethylene glycols plants are highly integrated units where ethylene oxide from the ethylene oxide reaction system can be recovered as glycols with a co-product of purified ethylene oxide if desired. Privacy Policy. It is a colorless, practically odorless, with low viscosity, hygroscopic liquid at room temperature. The process of natural gas dehydration is very important in: gas-pipelines, -storage, and –marketing. In the described process, MEG is produced via EO, which is manufactured in an integrated plant utilizing Shell EO technology. Already a Chemical Engineering gold or platinum member? Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts. None UN NO. Shell OMEGA is the first process to enable ethylene glycol production via a fully catalytic process. Ethylene glycol (MEG) is a colorless liquid, utilized in the production of antifreeze, polyester fiber, PET bottle resins, polyester film, and a variety of other applications, including aircraft and runway deicing fluids. The Flow diagram of Ethylene Glycol plant. An economic evaluation of the process was conducted based on data from the first quarter of 2015, assuming a facility with a nominal capacity of 750,000 ton/yr of MEG constructed on the U.S. Gulf Coast.
