GTI has a strong legacy in our characterization of unconventional gas resources—accurate mapping of the resource and determination of the total size, volume, distribution and nature of the gas—used to tailor production mechanisms to the characteristics of the formation and develop an appropriate technology roadmap for resource development.
We are exploring ways to reduce well costs to produce gas in economically marginal areas and developing fit-for-purpose equipment to access resources in challenging terrain. GTI has expertise in geologic evaluation, core sample analysis, casing design and placement, and well completion processes. We are currently evaluating the feasibility of using high-power lasers for much more rapid, cost-effective and environmentally benign well construction and completion.
GTI is enabling environmentally sound and cost effective management, by-product recovery, and beneficial use or reuse of produced water streams. We have led a number of Water Conservation and Management Committees in U.S. shales and assessed water management and reuse technologies. Researchers are utilizing water-based life cycle modeling to provide timely planning and technology guidance for sustainable shale gas water and solid waste management.
GTI leads a variety of R&D programs directed at small-scale natural gas liquefaction, co-producing gasoline and power from natural gas, the use of LNG as a transportation fuel and in other applications, interchangeability, and the compatibility of LNG with gas from other sources. We provide information resources and offer training courses that provide an overview of the LNG industry, terminal design and operations, and thermodynamics.
GTI held the first LNG Conference in Chicago in 1968 and remains one of three official sponsors. We have published the Proceedings from LNG-1 to LNG-16, and our publications are essential sources of information for anyone involved in the LNG business.
GTI is working with partners on developing thermal conversion solutions for solid hydrocarbon feeds. GTI is a leader in developing, proving, and implementing gasification technologies and integrated systems for converting coal, pet coke, biomass, and other solid fuel feedstocks into syngas and optimizing system design.
We have extensive knowledge in the design, construction, and operation of entrained-bed, fluidized-bed, and moving-bed gasifier systems, using more than 25 feedstocks. GTI has experience in the production and conversion of syngas to ultra-clean liquid transportation fuels through catalytic synthesis, such as the Fischer-Tropsch process and Haldor Topsøe TIGAS® processes.
We work on catalytic gasification, hydrogasification, and partial oxidation gasification processes to produce pipeline-quality substitute natural gas (SNG), and have also used natural gas reforming and water electrolysis to produce hydrogen. Our advanced pyrolysis approaches have the ability to convert non-food biomass feedstock—such as wood, agricultural residues, algae, and aquatic plants—directly into gasoline, diesel and jet fuels.
GTI provides technical and economic process expertise and solutions for comprehensive fuels processing. We are developing new technologies to lower the cost of upgrading subquality gas to pipeline and LNG specifications and to provide better approaches to meeting environmental regulations of gas processing facilities. Major areas of expertise include acid gas removal, sulfur recovery, H2S scavenging, and natural gas dehydration. We also have experience in applying membrane and solvent technologies to separate and capture carbon dioxide from exhaust streams as part of a carbon sequestration strategy.
We are exploring a variety of syngas cleanup options and systems integration for improved alternate fuels production economics, reliability, fuel quality, and CO2 removal. We develop and assess membrane, sorbent, and solvent-based technologies, enabling us to separate and capture components such as CO2 from process streams. Capabilities include the development of a catalytic tar cracking process for biomass-derived syngas cleanup; development of membranes to separate hydrogen or carbon dioxide from syngas and ethanol/water and butanol/water separation for bioreactors; and conditioning of biogas to meet pipeline specifications and for use in end-use equipment and appliances.
