Abstract
Requirements for water pollution abatement have created a need for much better recovery of fatty material from soapstock acidulation processes. The present methods of recovery lack reliability, or are relatively capital intensive, or both. A new, continuous system con-sisting of equipment for acidulating the soapstock, decanting the bulk of acid oil from acid water, and treating the acid water in a coalescer for further separation of emulsified acid oil is described. The emphasis is on operating results from a pilot process using a variety of soapstocks. Fat concentrations below 150 ppm in acid water can be achieved reliably. The process is relatively compact, and simple to operate.
