Waste continued collection costs

Acidulation is one of the least desirable processes in the integrated facility. Not only is the process rather difficult to perform effectively, but it generally represents a cost without significant return. Figure 16 depicts a typical acidulation system based on gravity separation. The separations can be performed in either a continuous or batch operation. In operation, soapstock, discharge streams from tank farm collection systems, and other waste streams enter a equalization or holding tank. The facility may or may not add additional caustic at this point to saponify the... 

Compliance with biohazard and chemical waste management regulations continues to be one of the most significant issues in any laboratory. Chemical waste, either stock or reagent, should never be poured down laboratory drains. Instead, it should be collected into appropriate and clearly identified ( HAZARDOUS WASTE ) containers prior to removal by waste management services. Chemicals and reaction products should never be mixed. Not only is the practice dangerous but also creates additional costs in terms of dealing with the waste.
