For example, a refinery must process a very heavy crude with a low volume of compounds in the gasoline boiling fraction range. This means that a larger share of heavy oils will be produced. The engineer will need to adjust conditions in these downstream units to accommodate the additional volume. Agriculture Your engineering group has been asked to provide for your company's plans to build a large fermentation-based lactic acid plant. Part of the justification for the plant is that the route your company will use results in much less carbon dioxide released to the atmosphere.
Lactic acid is a naturally occurring organic acid, which is present in sour milk and molasses.
It is also widely used in dyeing and printing. Its formula is C3H6O3 and chemists also call it 2-Hydroxypropanoic acid. That process was simple, but the plants were large and costly. Monsanto began making lactic acid s precursor by a synthetic route at its Texas City, Texas plant at that time. The plant is now owned by Sterling Chemicals.
