ADIP ULTRA: for cost-effective, enhanced removal of CO2

Gas development projects face growing challenges from resources containing increasing amounts of CO2, tighter sales specifications and stricter environmental emission standards. At the same time, operators in the oil and gas industries are looking for solutions to debottleneck existing plants while reducing their operating costs and carbon footprint.

Article Summary

Gas development projects face growing challenges from resources containing increasing amounts of CO2, tighter sales specifications and stricter environmental emission standards. At the same time, operators in the oil and gas industries are looking for solutions to debottleneck existing plants while reducing their operating costs and carbon footprint.

The Shell Catalysts & Technologies ADIP ULTRA gas-treating process for CO2 removal is an ideal solution for helping to meet these requirements in grassroots applications and solvent swap revamp situations.

About the technology
Shell Catalysts & Technologies has a long history of developing gas-treating processes; ADIP technology, for example, dates back to the 1950s. Since then, more than 500 Shell operating facilities and licensees have applied the technology, and it has established a track record of high levels of performance and reliability.
Moreover, the organisation continues to improve the technology. In 2000, it introduced ADIP-X technology, which features a significantly upgraded solvent that unlocked a step change in CO2 removal capability. The latest generation came in 2017 with ADIP ULTRA, which has several enhanced design features that reduce the cost of CO2 removal even further. A typical ADIP ULTRA process line-up is shown in Figure 1.
  
Solvent description
ADIP ULTRA technology uses two amines, methyl diethanolamine (MDEA) as the main reactant and piperazine as the accelerator, and water.
It can help to reduce the capital and operating costs of grassroots plants and revamps owing to the solvent’s high capacity for CO2 and hydrogen sulphide removal, and its low circulation compared with using aqueous MDEA.
ADIP ULTRA solvent can facilitate efficient and stable operations owing to its characteristics of low levels of hydrocarbon solubility, foaming, fouling, corrosion and degradation.

Business Value
The ADIP ULTRA gas-treating process cost-effectively treats gases with high CO2 levels. Compared with conventional process line-ups it can help to:
-    reduce equipment costs by up to 30%;
-    cut regeneration energy requirements by up to 30%;
-    capture up to 25% more CO2.
All the solvent chemicals can be sourced on the open market.
