New Anthracene Paste Plant for El Nasr, Egypt. Detail Engineering to implementation comprising anthracene oil treatment, cooling, crystallising, centrifuging and bagging/palletising of anthracene paste.

Detail engineering and implementation for a 25 tons per day carbon regeneration plant for Thames Water. Activated carbon is used for water purification in the water industry. When the activated carbon is saturated with impurities adsorbed from the water, it is sent away for processing so that it can be reactivated and reused as activated carbon is an expensive commodity. This detail engineering project was for a plant to reactivate the carbon. The plant design included the receipt and unloading of the carbon slurry from road tankers into silos, tanker scheduling and storage requirements, transfer of the carbon from silos, using eductors, for regeneration into a multi hearth furnace. Low pressure steam injection into the hearth to maintain an air free atmosphere. A separate steam injection system into the hearth furnace central shaft to provide cooling and temperature control of the carbon. The discharge of the hot activated carbon into water cooled silos. The design of power regeneration facilities using steam turbines from the steam generated in the reactivation process. Scrubbing and filtration of the hot gases prior to feeding into a thermal oxidiser and then for disposal via a stack. Design of the optimum configuration of heat exchangers and interchangers for thermal efficiency of the process.
