Methyl Ethyl Ketone is one of the top 100 chemicals produced worldwide due to its high demand and versatile end use. This article will analyze and compare methyl ethyl ketone production processes using patent-protected methods from two of the industry's chemical production leaders, Maruzen Petrochemical Co. and ExxonMobil Corp. The analysis of the two methods of producing methyl ethyl ketone will allow us to highlight the evolution of the production process over time and the impact of these processes on energy consumption and waste production. Comparing the patented methyl ethyl ketone production method of the world's leading methyl ethyl ketone producer, Maruzen Petrochemical Co., with ExxonMobil Corp.'s patented method. and the conventional method, we will be able to determine the most favorable process based on their environmental impact, turnaround time and energy consumption. Many industries use methyl ethyl ketone, particularly the automotive, electrical, and furniture industries. The main application of methyl ethyl ketone is in the paints and coatings industry, which contributes half of global demand. Methyl ethyl ketone exists in many consumer products available around the world. A few consumer products containing methyl ethyl ketone will be selected and their chemical composition will be broken down and analyzed to see what role methyl ethyl ketone plays in the composition of the products. Production of methyl ethyl ketone by Maruzen Petrochemical Co. Maruzen Petrochemical Co., located in Tokyo, Japan, is the world leader in the production of methyl ethyl ketone. Maruzen Petrochemical Co.'s patented process for producing methyl ethyl ketone is quite simple using paper..., while in Europe and North America there is not much need or growth for methyl ethyl ketone. .1 Growth is expected to increase at an average rate of 1.9% over a 4-year period between 2010 and 2014, with most of the growth coming from the Asian market.1 As we move into the future, it is It is evident that methyl ethyl ketone will continue to play a key role in the chemical industry. New processes are being developed to produce methyl ethyl ketone in a much safer and faster manner, with less energy consumption and less environmental impact, as illustrated by Maruzen Petrochemical Co's patented process. As more applications and uses of methyl ethyl ketone are discovered, the demand for this chemical compound will increase and thus motivate chemical manufacturing companies to research and develop new methods and tools to produce. methyl ethyl ketone..
