TBT: Dynamic Alarm Management on an Ethylene Plant

Katherine Persac

ProSys is joining the Throwback Thursday trend and will begin posting a series of blogs and whitepapers from years gone by. To start off, here is a paper that our founder, Les Jensen presented at the Honeywell User’s Group EMEA in Nice in 1995. Les presented the paper jointly with one of our European customers, ÖMV. The data presented in the paper is collected from the alarm management project that ProSys implemented for ÖMV. Stay tuned for more oldies but goodies in our #TBT series.

A little history on “Throwback Thursday” from

Throwback Thursday is an Internet theme day observed on every Thursday during which people share an old photograph of themselves via social networking sites and image-sharing communities, most notably through photo-sharing mobile app Instagram. Its origin has been associated with things that are deemed classic or vintage since as early as 2003 when the term was first defined. The earliest mention of “TBT” can be found in the title of a series of revamped retro cartoon characters illustrated by animator Saxton Moore and uploaded onto his blog in January of 2006. In July of 2006, the sneaker fan blog Nice Kicks launched their own TBT series highlight a selection of once-popular vintage sneakers and the series continued through June 2012. In 2011 the phrase began to gain more popularity in the blogosphere. By November 2011 the hashtags #throwbackthursday and #tbt have become an established trend, and as of May 2013 these tags have been used about 25 million times. More than 90,000 people used these hashtags on Twitter in the first week of January 2012 alone. It has continued to grow and remains relevant today.
