Composition Measurement in Ethylene Plants

An Ethylene Plant is a process for the produc-tion of polymer grade ethylene (99.9 vol %). It also produces major byproducts such as propyl-ene (chemical or polymer-grade), a butadiene rich C 4 stream and C 6-C 8 aromatics rich pyroly-sis gasoline. The Ethylene Plant is the major supplier of feedstock to the polyethylene plants for the creation of polyethylene plastics. The first section of ...

MacView Ethylene Postharvest Portable Analyser | EMS

Ethylene (ISO-name ethene), is a plant hormone that is produced by trees, plants, vegetables, fruit, flowers and tulip bulbs. Several cultivars of these vegetations are extremely sensitive for the presence of ethylene in air. Ethylene cause a trig- ger of ripening and is thus a stress-hormone that can cause irreversible damage to the stored product. Monitoring of ethylene …

Process Design for the Production of Ethylene from Ethanol

After conducting an analysis of the sensitivity of the plant’s Net Present Value and Internal Rate of Return to ethylene and ethanol prices, it was determined that while profitability is not attainable in the current market (which prices ethanol at $0.34/lb and ethylene at $0.60/lb), profitability is attainable should ethylene prices rise to $0.64/lb and ethanol prices fall to $0.305/lb ...

01/10/2004· In this study, we used kinetic analysis of growth to further examine details of growth inhibition by ethylene in wild-type seedlings and seedlings with mutations for one or more genes in the ethylene signal transduction pathway. We tested whether rapid growth inhibition was altered in mutant seedlings lacking the two transcription factors EIN3 and EIL1 or the Nramp-related protein EIN2.

Gas Chromatography: The Modern Analytical Tool

Just like fuel dilution, ASTM D4291 covers the use of gas chromatography to detect trace amounts of ethylene glycol due to coolant leaks; another method specifically developed for used oil analysis. In the case of ethylene glycol, the method works by first extracting the glycol using water (because ethylene glycol is a polar molecule, it is easily extracted using water) and injecting it into a ...
