MTR unveils new solvent dehydration product line for dehydration of Ethanol, Isopropanol, Acetonitrile and THF(April 2017)


MTR has been developing cutting edge membrane products for dehydration of various hydrophilic and hydrophobic solvents and has now launched a highly successful membrane process for solvent dehydration.

Many commercial hydrophilic solvents form azeotropes or have vapor-liquid equilibrium (VLE) pinch points with water, which makes solvent recovery by conventional distillation difficult. Solvents that form such azeotropes or have such pinch points include isopropyl alcohol (IPA), acetone, methyl ethyl ketone (MEK), ethyl acetate, ethanol, butanol and tetrahydrofuran, etc. Molecular sieve drying is possible, but is energy intensive and is generally not economical for situations where the water concentration is more than 2-3 wt%. Pressure swing distillation or extractive distillation is often used for feed streams containing more than a few percent water, but the capital cost of the columns needed is an issue, as well as the high operating cost caused by the high steam consumption of the distillation process.

Our zeolite membrane process offers a simple alternative to distillation technology. Vapor permeation of water through the robust zeolite membrane allows almost complete recovery of dry organic solvent, which can be reused without further processing or treatment. The water content of the solvent is reduced to the 0.1 to 1.0 % range.

First of Three Hydrogen Membrane Units for KNPCs Clean Fuels Project Getting Ready To Ship (January 2016)


MTR is providing three large membrane units for Kuwait National Petroleum Company's (KNPC) Clean Fuels Project (CFP). The CFP involves the upgrade and integration of the Mina Abdulla (MAB) and Mina Al Ahmadi (MAA) refineries in Kuwait, increasing capacity of the refineries, and reducing sulfur content. The $16bn CFP project is scheduled for completion in mid-2018.

Among the many new components at the two refineries, three Atmospheric Residue Desulphurization (ARDS) units will be installed (licensed by Chevron Lummus Global), two at MAB and one at MAA. The ARDS process requires large amounts of high purity hydrogen, and each of the three ARDS units includes a Hydrogen Membrane Unit (HMU) to recover and recycle purified hydrogen.

MTR is providing all three HMU's (2 HMUs purchased for MAB by the EPC JV of CB&I, Petrofac, and Samsung Engineering; and 1 HMU purchased for MAA by the EPC JV of JGC Corporation, GS Engineering & Construction, and SK Engineering & Construction. These HMU's are among the largest hydrogen units built by MTR, and the first will ship to the site next month. .

MTR Starting Up Multiple Large Gas Conditioning and Liquids Recovery Skids for Compressor Stations in the Northeast. (December 2014)

MTR was awarded  multiple contracts in Q1-2014 for design, construction and delivery of several gas conditioning skids including liquids recovery for large compressor stations in the Northeast. These skids were delivered and the first unit has been successfully started up in December 2014 despite the extremely cold weather conditions prevalent at the time of startup.   The MTR skid which utilizes a patented process design is generating significant natural gas liquids at the facility and thereby reducing BTU values to below 1000 BTU/SCF for use as fuel gas in multiple gas engines installed at the site.  Other similar skids will be started up in early 2015 for other stations for the same company.

Liquid CO2 Successfully Produced in Pre-Combustion Capture Syngas Demo at NCCC (January 2014)

MTR recently completed a project with DOE to develop a membrane-based process that effectively and efficiently captures CO2 from shifted syngas generated by a coal-fired IGCC power plant.  The successful development of this low-cost, environmentally benign membrane technology can potentially result in substantially improved economics for IGCC power production with CO2 recovery, making this combination of technologies a practical approach to environmentally friendly generation of electricity.The CO2-selective membranes (Polaris™) used in this project were developed and tested in three phases: laboratory testing of membrane stamps, pilot-scale testing of small membrane modules at a syngas processing plant, and full membrane system demonstration of liquid CO2 production from raw syngas.  The third phase field test was conducted with a pilot-scale membrane skid using a real coal-derived syngas, at a syngas processing plant operated by the National Carbon Capture Center (NCCC), Wilsonville, AL. The demonstration system processed 500 lb/hr of syngas (equivalent to the syngas that could be produced at a 0.2 MWe IGCC power plant), and produced a liquid CO2 stream containing 98+% CO2, starting from the coal-derived syngas feed, which contained only ~9% CO2.

The Polaris membranes prepared in this work are at the early commercial stage of development.  Several membrane systems using these membranes have been sold for CO2 removal from mixtures with H2 in various refineries, and MTR is exploring other opportunities to prove the technology reliability and demonstrate the process economics to a broader array of customers.  In particular, additional scale-up work would validate design studies which showed that a combination of CO2-selective membranes and H2-selective membranes can further improve the membrane process efficiency for CO2 capture.
