Research & Testing

Superheated and Subcooled Liquid Releases of: Water, Freon-11, Chlorine, Methylamine, and Cyclohexane
A series of experiments using water, Freon-11, Chlorine, Methylamine, and Cyclohexane as test fluids was conducted for the Center for Chemical Process Safety (CCPS). The purpose of the experiments was to determine the behavior of superheated liquids as they were released from pressurized storage to the atmosphere. The amount of liquid falling to the ground (rainout) and the amount remaining in the vapor stream (aerosol) were measured as a function of storage temperature, storage pressure, and release orifice diameter. The data from the experiments was compared to the predictions of the CCPS “RELEASE” model. Based on the results of the comparison, enhancements to the “RELEASE” model were developed.

Sulfuric Acid Releases
Releases of alkylation sulfuric acid and emulsions of sulfuric acid and alkylate were released to determine the amount of sulfuric acid that would fall to the ground when released from a pressurized stirred vessel. The tests, conducted as a Petroleum Environmental Research Foundation (PERF), and showed that little sulfuric acid enters the air stream upon release.

Hydrogen Fluoride Releases
Releases of anhydrous hydrogen fluoride and hydrogen fluoride mixed with proprietary additives were conducted to determine the effectiveness of the additives in suppressing the formation of an airborne aerosol. Tests were conducted over a two-year period to determine the effectiveness of the additives as functions of temperature, release rate, and additive concentration.
