Continuous Processing

30. Examples of batch processes
Pharmacuticals (substances with medicinal properties)
Agrochemicals (pesticides, fertilizers, fungicides)
Dyestuffs (food dyes, clothing dyes, industrial dyes)
Food additives(preservatives, enhancers, the ‘E’s infood)
Perfumes
Vitamins
Pigments

31. Advantages of batch processes
Good for small amounts of speciality chemicals
Make a range of products using same equipment
Can schedule maintenance & inspections to equipment in between batches
Good for developing new products
Easier to scale up from lab scale
Generally cheaper set up costs
Employees understand the process well

32. Examples of Continuous Processes
Sulphuric acid production
Sodium hydroxide production
Ammonia
Petrol
Chlorine
Methanol

33. Advantages of Continuous Processing
Good for large volumes (bulk chemicals)
Fewer start up and shutdowns – UPTIME!!
Potentially greater yields
Potentially easier to maintain quality or spot out of specification product sooner
