LabDELTA™ Strong Acid
Neutralization Systems
Strong acid,
concentrated acid, superacids such as Oleum or Chlorosulfonic
Acid, require a special neutralization strategy. With these
chemicals, operator or technician safety is a primary concern.
Automating the neutralization process with Wastech's
LabDELTA™ systems takes the operator out of
harm's way.

In addition to the highly
corrosive liquid and vapors, heat is a constant issue. When
neutralizing concentrated acids with 50% caustic, an exothermic
reaction will generate heat. Heat can cause boiling and even
explosions in unvented areas.
Normally the water volume itself
can act as a heat sink to dissipate the heat. In extreme cases, a
heat exchanger made of PVDF or PP will be installed in the
reaction tank using factory supplied chilled water. High
temperature materials (CPVC, PP or Teflon) for piping, metering
pumps and tanks may be required. Stainless steel mixer shafts
may need to be coated in Teflon.

In less severe cases, the reaction
will be slowed to allow heat to dissipate by slowly adding the waste
to the reaction tank or diluting the chemicals by adding the waste
slowly to a large water volume. Regardless, the temperature will be
automatically monitored with an alarm and a shutoff of the chemicals
in the alarm mode. Larger
tank volumes, double containment, equalization or holding tanks,
longer reaction times and responsive controls are all considered in
the engineering of a
LabDELTA™ solution.
