teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as pre-separators. Bag filter failure is consequently a very common problem for clients in this industry. Client`s needs include a very robust dedusting system, either serving as end-stage collector avoiding the need to cool down flue gases, or strongly minimizing the loads of aggressive material to bag filters.

A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face during their operation, leaks can and do develop. When a heat exchanger leaks, xylene contaminates the steam and produces a number of problems ranging from loss of final product, contamination and fouling of steam transfer piping, and ultimately bio-fouling of cooling towers. Consistent and reliable monitoring for xylene or other petroleum hydrocarbons in cooling water or steam condensate can alleviate product loss and process equipment down time.
