LPG and Amine Solvent Emulsion Formation

{0 Comments}

When a liquid hydrocarbon travels across the amine solvent inside the amine unit contactor (treater) and liquid pockets or droplets cannot break the interfacial structure, they become encapsulated in the amine solvent aqueous liquid phase and form what is commonly referred to as emulsion. Emulsion is essentially a liquid droplet that will not merge (coalesce) […]

LPG Treating Surfactant Contaminants

Surfactants in the liquid LPG hydrocarbon phase feeding amine units can cause a number of detrimental eff ects, most predominantly LPG-amine solvent emulsification. Surfactants can also be present in the water phase if the LPG contains emulsified or free water. Emulsion formation inside the amine unit contactor (treater) can then lead to several secondary problems […]

Influencers of NOx Chemistry

Regenerator design A well-mixed or counter-current regenerator configuration will help minimise NOx emissions. An example is the higher efficiency combustor regenerator which is renowned for having amongst the lowest NOx emissions in the industry. Carbon monoxide promoters All CO promoters will have a negative impact on NOx emissions but platinum based promoters are the worst. […]
