HighNew is a specialized company for amine purification equipment and services. We continuously remove Heat Stable Salts (HSS), suspended solids, and hydrocarbons from amine circuits.

Our Amine Purification can result in:

 Increased product quality
 Reduced process upsets
 Less equipment maintenance and energy consumption
 Reduced amine loss
 Reduced foaming
 Reduced filter consumption

HEAT STABLE SALTS (HSS)
Organic Amine reagent is usually used to remove H₂S and CO₂from natural gas and oil industry In the Aminedesulfurization process. Due to the decomposition of the Amine solvent, trapscontaminates and particles from the raw material, etc, these negative ions arecontinuously accumulated in the Amine, which forms the HHS. These negative ionsin the Amine cannot be removed by steam stripping at high temperatures (120 ℃) and therefore it isdefined as HSS (heat stable salts), such as:Cl-,SO₄^2-, HCOO^-, CH₃COO^-, C₂O₄^2-, SCN^- , S₂O₃^2-ions etc..

Procautions of the HSS
Based on the research and operational experience in China, the concentration of HSS needs to be controlled to below 1%wt. Continued accumulation of HSS over this level results in many issues.
