MDEA Solvent Change: What Process Data Should Buyers Prepare?

A gas treating plant is reviewing a new N-methyldiethanolamine (MDEA, CAS 105-59-9) supply option. The purchasing team has the required quantity and delivery date, while the process team needs to confirm suitability for the unit. Preparing a concise operating summary helps both teams assess the proposed grade.

Start with the current solvent and treating target

Record the approved solvent name, formulation reference and operating concentration. State whether the project concerns a new source of the same specified grade or a proposed formulation change.

Include the required treated-gas H₂S and CO₂ limits. MDEA is widely used for selective H₂S removal, and commercial gas treating formulations can be tailored to specific duties. energy-resources.basf.com

Provide feed gas and operating conditions

Ask the process team to prepare the feed gas composition, flow range, pressure and temperature, with units and a clear reporting basis. Identify normal conditions and any expected changes that the review should cover.

Include available absorber information and the current solvent circulation rate. BASF’s technical discussion identifies lean amine temperature, gas pressure, absorber internals, column height and the liquid-to-gas ratio as factors affecting mass transfer. energy-resources.basf.com

Describe the reason for the review

Explain whether the plant is addressing supply availability, a revised feed composition, a new outlet specification or an operating concern. Where relevant, attach recent solvent analyses and performance records with their sampling dates and operating conditions.

This gives the process reviewer a defined question to assess and helps identify any further data needed.

Connect technical approval with the purchase schedule

Ask the plant’s process authority to confirm the required evaluation and approval steps. Coordinate those steps with sample availability, batch documentation and the intended delivery window.

For a quotation from China Amines Co., Limited, provide the approved grade or proposed specification, required quantity, packaging and destination port. Include the technical review timeline so we can assess supply and documentation requirements alongside the commercial inquiry.
