Ethylene Recovery from Ethyleneoxide Unit Offgases

This paper depicts one possibility how to increase the benefit at the Ethylene oxidation 2 unit in Bratislava Refinery. The refinery offgases can contain valuable components e.g. ethylene, propylene or hydrogen, which are used only as fuel gases. There are some possibilities, how to remove them from the offgas stream and use as important raw material.

My report deals with Ethylene oxide 2 unit offgases. This stream contains high percent of ethylene and it is possible to take the ethylene out and continuously stream it back to the process. Thanks to this process, the raw material´s cost will be less. The process is cheap and simple and the return on investment time is short.
