  • METHOD OF PRODUCING PLASTICIZER AND REDUCING ENERGY CONSUMPTION
    Publication number: 20200115314
    Abstract: Systems and methods for producing a non-phthalate based plasticizer. The systems and methods involve dissolving a carboxylic acid and/or anhydride thereof in an alcohol at a temperature below the melting point of the carboxylic anhydride. An advantage of the method is reduced energy consumption compared to conventional methods that require melting the carboxylic anhydride. Furthermore, the method enables the production of non-phthalate based plasticizer in an existing phthalate based plasticizer production facility with minimal modification, thereby reducing capital expenditure.

  • Gaseous byproduct removal from synthesis gas
    Patent number: 8535418
    Abstract: A method of removing gaseous byproducts from a gas stream includes generating via at least one partial-combustion device a gas stream that includes gaseous byproducts. The method also includes channeling the gas stream from the at least one partial-combustion device to a fluid compression device that is configured to increase a pressure of the gas stream. The method further includes channeling the gas stream to a gaseous byproducts removal system to absorb at least a portion of the gaseous byproducts from the gas stream using a solvent. The method also includes discharging at least a portion of the gaseous byproducts from the gaseous byproducts removal system.

  • System and method for improving performance of an IGCC power plant
    Patent number: 8529679
    Abstract: In certain embodiments, a system includes a gas cleaner. The gas cleaner includes a solvent to clean a syngas. The system also includes a heat exchanger configured to heat a liquid to generate a vapor. The system further includes a vapor absorption refrigeration (VAR) cycle coupled to the gas cleaner and the heat exchanger. The VAR cycle is configured to cool the solvent. In addition, the vapor drives the VAR cycle.
