Renewable Energy
Monitoring waste storage T
he Seche Group and its subsidiary Tredi have chosen ARC Informatique´s PcVue to set the standard for its
plants, including household and industrial waste incineration plants, and biogas power plants. Since its first deployment in 2005, it can now be found in 16 plants and workshops, representing more than 500 000 variables being processed, applied and logged by PcVue. Séché Environnement has more than 20
processing sites in France. Its original position, downstream from collection activities, puts it at the very heart of the most technically demanding industry. Tredi is a subsidiary specialising in hazardous industrial waste. The range of materials processed is immense, covering any waste which cannot be treated like household refuse. A team of control engineers has been
working since 2003 to develop a library of generic objects specific to each of the group´s activities, and to introduce suitable ergonomics and control elements. The group
has decided that it will oversee development of the chosen control system in order to ensure as far as possible that it can be standardised and rolled out efficiently, quickly and consistently across its other plants. So the control applications can easily be grouped together in one single physical location: for some tasks, logging and reporting are already centralised. The PcVue solution was first
installed at the industrial site in Salaise sur Sanne, France, in 2005. This is Seche Group´s largest heat processing and energy recovery centre: it processes around 250,000 tonnes per year made up of hazardous waste (HW), non- hazardous industrial waste (NHIW), household waste and infectious clinical waste. This first deployment involved the water treatment unit. The priority was to define object standards and a whole special library was developed for PcVue and the logic controllers. The decision was taken to adopt OFS-based communications. PcVue was then progressively
introduced into units 1, 2 and 3 at the Salaise site. We started with a complete revamp of Salaise Unit 1, with its two rotary furnaces: Here, PcVue supervises all process functions and common tasks,
meaning about 30,000 variables are being monitored. Then, with the partial revamping of Salaise 2 following the installation of a new waste injection system, allowing it to operate in sealed mode; this revamp followed the signing of the waste treatment contract which resulted from the illegal dumping of the Probo Kpala cargo in Ivory Coast. And finally Salaise 3, where the replacement of the control system is currently under way. Rockwell process logic PLCs are to be replaced by Telemecanique PLCs under Unity and PcVue (two input/ output servers and 5 client stations). PcVue has been installed at the Drimm
storage centre near Toulouse and the Changé plant just outside Laval, France. PcVue is also installed at the SVO site in Vienne, and the Opale site in Nord Pas de Calais. l

Advanced plant for waste-to-biofuels
tto Simon Ltd has signed a direct agreement to support Enerkem, a Montreal-based waste-to-biofuels
and advanced chemical company, in the design and construction of two ground breaking biofuel projects in Canada and the US.
Each project will employ Enerkem’s
thermo-chemical gasification and catalytic synthesis technology to convert diverse feedstock’s including sorted municipal solid waste, construction waste and treated wood to produce methanol, ethanol and other specialty chemicals. The facility design has been standardised and is based on high level of modularisation
for rapid market penetration. Drawing upon their own experience
in associated processes, Otto Simon will complement Enerkem’s own in-house operations group, providing value added engineering and project delivery support. Otto Simon secured the position alongside
Enerkem following a period of interaction in which synergies were identified. Otto Simon is also working with Enerkem on behalf of a project developer at an advanced stage in applying Enerkem’s gasification technology on a waste to energy plant in the UK. The appointment in support of Enerkem
continues Otto Simon’s progressive success in supporting project developers/investors and their delivery expectations in the emergent new fuels and energy sectors. l
