Development of hydrogen compatible chemicals and test methods for energy sector application

Abstract

The present disclosure provides compositions and methods for use with hydrogen gas. A method may include adding hydrogen gas to a medium and adding a production chemical to the medium. As examples, the production chemical may be a corrosion inhibitor, an anti-foulant, a hydrate anti-agglomerate, a kinetic hydrate inhibitor, an amine for gas sweetening, a regenerable H 2 S scavenger, a non-regenerable H 2 S scavenger, an alcohol for gas dehydration, an alcohol for hydrate control, a thermodynamic hydrate inhibitor, or any combination thereof. The present disclosure also provides test methods to determine the susceptibility of a production chemical to reaction with hydrogen gas.

 adding hydrogen gas to the medium, and   adding a production chemical to the medium.   
     
     
         2 . The method of  claim 1 , wherein the hydrogen gas is added before, after, and/or with the production chemical. 
     
     
         3 . The method of  claim 1 , wherein the production chemical comprises a corrosion inhibitor, an anti-foulant, a hydrate anti-agglomerate, a kinetic hydrate inhibitor, an amine for gas sweetening, a regenerable H 2 S scavenger, a non-regenerable H 2 S scavenger, an alcohol for gas dehydration, an alcohol for hydrate control, a thermodynamic hydrate inhibitor, or any combination thereof. 
     
     
         4 . The method of  claim 1 , wherein the medium is present within a pipeline, a gas processing plant, a refinery, an ethylene plant, or any combination thereof. 
     
     
         5 . The method of  claim 1 , wherein the medium is not present within a subterranean formation. 
     
     
         6 . The method of  claim 1 , wherein the hydrogen gas and the production chemical are not added to a subterranean formation. 
     
     
         7 . The method of  claim 1 , wherein at least some of the hydrogen gas is added separately from the production chemical. 
     
     
         8 . The method of  claim 3 , wherein the corrosion inhibitor is selected from the group consisting of an organic sulfur compound, an imidazoline, a carboxylic acid, a fatty acid amine condensate, a substituted fatty acid ester, a substituted aromatic amine, a phosphoric acid ester, a quaternary ammonium compound, or a compound comprising multiple positive charges. 
     
     
         9 . The method of  claim 1 , wherein the hydrogen gas is combined with a hydrocarbon before being added to the medium. 
     
     
         10 . A method, comprising:
 adding a production chemical to an autoclave,   adding hydrogen gas to the autoclave,   monitoring a pressure within the autoclave, and   determining if the hydrogen gas reacted with the production chemical.   
     
     
         11 . The method of  claim 10 , wherein a Pd/C or a transition metal catalyst is added to the autoclave. 
     
     
         12 . The method of  claim 10 , wherein the autoclave comprises about 500 to about 1,000 psig of the hydrogen gas before the monitoring step commences. 
     
     
         13 . A method of inhibiting embrittlement or cracking of a surface in contact with a medium, comprising:
 adding a composition to the surface and/or the medium, wherein the composition comprises a corrosion inhibitor and optionally a solvent and/or a production chemical, wherein the medium comprises natural gas, hydrogen gas, hydrogen sulfide gas, ammonia, or any combination thereof.   
     
     
         14 . The method of  claim 13 , wherein the corrosion inhibitor is selected from the group consisting of an organic sulfur compound, an imidazoline, a carboxylic acid, a fatty acid amine condensate, a substituted fatty acid ester, a substituted aromatic amine, a phosphoric acid ester, a quaternary ammonium compound, or a compound comprising multiple positive charges. 
     
     
         15 . The method of  claim 13 , wherein the medium is a wet gas medium, a dry gas medium, a dry gas medium comprising a gas condensate, a wet gas medium comprising a gas condensate, a wet gas medium comprising water and a gas condensate, an aqueous medium, a non-aqueous medium, an organic medium, a gaseous medium, and any combination thereof. 
     
     
         16 . The method of  claim 13 , wherein the medium is present within a pipeline, a gas processing plant, a refinery, a storage tank, an ethylene plant, or any combination thereof.
