It is generally difficult to accurately identify specific chem - icals that cause detrimental effects in processing facilities such as amine or glycol units. However, minimising and properly using the products causing foaming and/or solids formation will alleviate detrimental effects. In some cases, total replacement is necessary. Correct application of these products is also critical so that no unused or excess chemical is entrained in the inlet gas entering processing plants. In terms of mitigation, com - plete removal of chemicals entering the process via the inlet gas is likely not possible. Therefore, strict practices and provisions need to be in place to ensure minimal contam - ination ingression with the inlet gas. These practices and provisions include: u Water wash of the inlet gas using a highly effective water injection and extraction methods.  Install correctly designed gas filtration for solids removal from the inlet gas.  Install correctly designed liquids coalescing for liquids removal from the inlet gas.  Use proper high-efficiency elements (internals) with proper seals in both the inlet gas filter and coalescer.  Test for oxygen ingression with the inlet gas and mini - mise its presence if detected.  Ensure proper regeneration of the amine solvent to avoid possible cross-reaction with any contaminant entering the process and to minimise solvent thermal degradation. * All tables are available from the authors and included on the digital version of the article on DigitalRefining.com. Disclaimer Nexo Solutions received samples and SDSs of the various chemical additives from processing facilities for the specific objective of testing chemical compatibility with process solvents. None of these chemicals were tested or analysed for material composition or molecular types. David Engel is Managing Director at Nexo Solutions.
