| 20140200373 | FORMATE BASED HEAT STABLE SALT MITIGATION IN PHYSICAL SOLVENT ACID GAS ABSORPTION PROCESSES - There is described a process for reducing the concentration of formate based heat stable salts formed in a physical solvent acid gas absorption process ( | 07-17-2014 |
| 20140234191 | AMINOPYRIDINE DERIVATIVES FOR REMOVAL OF HYDROGEN SULFIDE FROM A GAS MIXTURE - The present invention relates to a novel class of aminopyridine derivatives with the general formula: wherein R | 08-21-2014 |
| 20140256944 | PROCESS FOR MAKING ALKOXYLATED PIPERAZINE COMPOUNDS - The present invention relates to an improved process for making mono- and di-alkoxylated piperazine compounds especially dihydroxyethylpiperazine. The improvement comprises the addition of an acid to the piperazine compound prior to the addition of an alkylene oxide to a reactor wherein the alkoxylated piperazine compound is prepared. Said improvement reduces the concentration of undesirable glycol ether byproducts which contribute undesirable color and foaming of the alkoxylated piperazine compounds. | 09-11-2014 |
| 20140330042 | PROCESS FOR MAKING ETHOXYLATED AMINE COMPOUNDS - An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds. | 11-06-2014 |
| 20150110695 | AQUEOUS ALKANOLAMINE COMPOSITION AND PROCESS FOR THE REMOVAL OF ACID GASES FROM GASEOUS MIXTURES - The present invention relates to an aqueous alkanolamine solution for the removal of hydrogen sulfide from gaseous mixtures. The aqueous alkanolamine solution comprises (i) an amino compound with the formula: R | 04-23-2015 |
| 20150112113 | Process For The Treatment Of Liquefied Hydrocarbon Gas Using 2-Amino-2-(Hydroxyethyl) Propane-1,3-Diol Compounds - A method for treating liquefied hydrocarbons comprising acid gases to remove said the gases while minimizing loss of amine species, the method comprising the step of contacting the liquefied hydrocarbons with an absorbent aqueous solution of a first amine compound, the first amine compound having the structure | 04-23-2015 |
