Amine chemistry in OLI MSE

Amines

20 amines including their hydrochloride salts were added to the MSE databank as part of the Chemistry in Refining Overheads project

OLI has added the chemical and phase behavior of 20 amines to the MSE databank. For each amine, OLI conducted an extensive and critical review of all available literature relative to the amines themselves and their associated behavior in the presence of hydrocarbons, CO2, and H2S.

The 20 amines include:

Return

Morpholine
N-Methylmorpholine
N-Ethylmorpholine
Ethanolamine
Diethanolamine
Dimethylethanolamine
Diglycolamine|
N-Methoxypropylamine
Dimethylisopropanolamine
Methyldiethanolamine

Methylamine
Dimethylamine
Trimetylamine
Ethylamine
Diethylamine
Propylamine
Butylamine
2-Butylamine
Cyclohexylamine
Ethylenediamine

These components are available in the current version of the OLI MSE databank.

This work was part of a larger scope of work, a multi-year research effort supported by the Chemistry in Refining Overheads Consortium. This OLI consortium attracted 13 leading companies from the oil refinery and supporting chemicals industry. The work commissioned by this group has created a comprehensive software and databank for predicting the phase behavior in refinery overheads including the formation of solid or liquid amine hydrochlorides.

Chemistry in Refining Overheads especially focused on predictions involving the associated amine hydrochlorides. These components may form in the refinery overhead streams and can cause serious corrosion problems. Since there was little published data for these amine hydrochlorides, OLI contracted with Laboratory for Thermophysical Properties (LTP) in Oldenburg, Germany and the Southwest Research Institute in San Antonio, TX USA to carry out experimental measurements of various properties for a large subset of the amine hydrochlorides. The remainder were estimated based upon the ones measured, using a group contribution approach.

Originally the parameters for the 20 amine hydrochloride solids and liquids were proprietary to the consortium. These parameters are now released in the OLI MSE databank, available to clients. The underlying experimental data for the project remains the property of the consortium. Any party interested in accessing this information can apply for a "late join" of this consortium.

OLI is interested in making the Chemistry in Refining Overheads application in the OLI software easier to use for clients. For this purpose, OLI invited the original consortium members to join a Chemistry in Refining Overheads special interest group. Work with this group is planned to begin in 2016, following the first release of the OLI Flowsheet ESP software.
