Safety in the Plant

When a company wanted to recycle over 36 000 t of sulphur, it needed a solution that, as Sean Ottewell reports, was not only readily-available and robust, but also capable of being dismantled and moved to other sites.
Als ein Unternehmen 36.000 t Schwefel aufbereiten wollte, brauchte es eine Lösung, die nicht nur einsatzbereit, verfügbar und solide ist, sondern die auch abgebaut und an andere Standorte verlegt werden kann. Ein Bericht von Sean Ottewell.
Quand une société a déclaré qu’elle souhaitait recycler plus de 36 000 tonnes de soufre, elle recherchait une solution non seulement facilement disponible et robuste mais aussi, nous explique Sean Ottewell, capable d’être démontée et déplacée dans d’autres sites.

ulphur is a by-product of diesel fuel that’s applied to the land as a fertiliser amongst its many other uses. Until recently, the market value of sulphur had remained
depressed for one the longest periods ever. This made the cost of recovery uneconomic so it was just stockpiled as a result. However, when the price increased five-fold, recovery became a profit opportunity for the owners of an oil refinery in Kenai, Alaska, USA. They contacted AIMM Technologies, a Texas-
based oil industry service-company with 15 years recycling/processing experience and long track record on the North Slope of Alaska.
“Alaska is a logistical nightmare in which to recycle petroleum by-products such as sulphur,” confirms Brooks Bradford, president of AIMM Technologies. “Sulphur is a hazardous material that can easily catch fire. For this contract, we had to bag the sulphur, move it to a storage site, move it from the storage site by truck to a port and then load it onto an ocean vessel for delivery to market. When we got the go ahead to recover the sulphur, we concluded that the best way was to use bulk bags. For this, we needed a means of filling them. One specific requirement was that the bagging facility had to be easy to dismantle for use at another sulphur recovery site once recovery at this site was complete.” “After researching various suppliers, we selected
