Product Description

AdapT 253 is a formulated MDEA-based solvent designed for total removal of acid gases from natural gas streams. As it consists of both a chemical and physical solvent component, it will also remove mercaptans to low concentrations.

The removal of sour or acid gas components such as hydrogen sulfide (H2S) or carbon dioxide (CO2) from gas streams is a common process, known as acid gas removal or gas sweetening. These impurities have to be eliminated or reduced to a specified level, for a variety of reasons: toxicity (H2S), corrosiveness of the gas, low caloric value, environment or other reasons depending on the application of the gas.

For over 50 years, alkanolamines have been used for acid gas treatment in natural gas and petroleum processing industries. AdapT solvent range is based on today’s most advanced and preferred alkanolamine for gas treatment technology: MDEA, and MDEA-based formulations.

Amine Gas Treatment Unit system simulation
Based upon feed gas conditions, the installation design and type of amine, unit performance can be predicted and optimized. The simulation output and reporting are tailored towards your needs and focus on the issues at hand. These simulations combined with our application experience allow us to provide you with feedback on how to improve the amine gas treatment unit operations (financial, operational and quality) and to tailor our amine formulations to maximize performance, such as energy reduction and reduced amine consumption.

Technical support
Technical support is provided to all AdapT users. Our experienced team of engineers is available around the clock to respond to your questions. On-site troubleshooting by an experienced engineer can also be arranged. Eastman can assist you with root cause analysis and operational recommendations for issues such as off- spec treated gas, foaming, high amine losses, high energy consumption, under capacity, corrosion etc.

Amine analysis
Detailed chemical analysis of your amine solution is a key tool to determine the overall quality of the system and identify the root cause for problems such as foaming, corrosion, off spec product etc. Eastman’s lab, highly experienced in amine analysis and interpretation, is at your disposal. Analysis of lean amine samples includes (a.o): sample appearance, physical-chemical properties, determination of free and bonded amine, acid gas loading foam test, metal scan etc.

The results of the analysis are interpreted by our specialist team and the necessary recommendations are provided. The frequency, content and reporting of the analyses is customized towards your needs. Full results are typically available within 7 working days after receipt of the samples.

Sample kits
Sample shipping kits and detailed analytical procedures are available to our customers upon request.

  • Bulk
  • Steel drums (215 kg net)

Stainless steel AISI 316 L is preferable for the storage of AdapT 253.

Copper and copper alloys should be avoided.

For bulk storage a nitrogen atmosphere is necessary to prevent the absorption of moisture and discoloration.
