Restarting the Plant After Annual Shutdown

Make sure that all statutory requirements and instructions given by inspecting authorities have been complied with. Some of these could be for boilers, economiser, steam lines, and electrical mains which have to be necessarily stopped for thorough cleaning and internal inspections. 

The date of restarting the plant shall be decided after discussing with sales department. The production engineers have to produce marketable grade material on restart. However, this may not be immediately possible, and hence, the date for restart may have to be advanced by a few days the time it would take to stabilise the plant and to produce marketable grade material). 

Storage tanks shall be made available to store the off-spec products or arrangements made to recycle/dispose of such material till proper quality products are getting produced. 

The schedule for restart shall be prepared by working ffie dates backwards. This will indicate which activity is lagging behind and needs to be accelerated. 

Check units at the end of production chain first (product purification/filtration/ distillation), cooling systems, other process units thereafter, and finally the feed end. Boxing up shall be done in the meanwhile, and start-up activities see examples below) shall commence only when all units are found to be in working condition.
