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

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

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

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
