The World of Batch - ISA 88 gives process automation a native language and much more

A Short History of the World ... of Batch "Batch manufacturing has been around for a long time," says Lynn Craig, batch guru and Process Automation Hall of Fame inductee. "Most societies since prehistoric times have found a way to make beer." That's a batch process. Its one of the oldest batch processes. Food processing and the making of poultices and simples (early pharmaceutical manufacturing) are so old that there is no record of who did it first. "The process consisted of putting the right stuff in. the pot, and then keeping the pot just warm enough, without letting it get too warm. Without control, beer can happen, but don't count on it. Ten years ago, or a little more," Craig continues, "batch, was a process that generally speaking didn't have a whole lot of instrumentation and control, and all of the procedures were done manually. It just didn't fit into the high tech world."
