Technology for health!

GRT develops processes and technologies through innovations that transform into commercial products or technology transfer to the widespread need. We perform research to produce durable hollow fiber membranes and red-ox flow battery at an affordable cost.

A semi-permeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane often used to remove bacteria and other microorganisms, particulates, and natural organic material, which can impart color, taste, and odors to water. Microfiltration, ultrafiltration, nano-filtration, and reverse osmosis are various types of semi-permeable membrane technologies. The advantages of membrane technologies are: flexible and reliable, less expensive, safe, larger surface area that affects more flux, absence of toxic materials and low environmental impact.

Several types of membrane technologies are available for different applications. By employing membrane filtration, any size of molecules in the feed solution could be filtered, i.e., from micro to nano level by carefully controlling its pore size. In principle, different sizes of molecules (largest to smallest size of particulates) can be filtered by microfiltration to RO membranes/nano-filtration. Hence, it is necessary to develop UF/NF hollow fiber membrane, which could give high efficiency with no contamination in the filtered water.

The working principle of UF/NF and RO is alike; both systems allow same types of filtrates with similar flux rates due to same pore size. However, the key difference between these two processes is that RO system operates only at high pressure (3-12 bars).

UF/NF is one of the most competent technologies that have excellent segregating capability of removing organic/ inorganic compound like dissolved natural organic matter, multivalent ions and micro- impurities. In UF/NF, the separation of molecules lies in the range from 200 to 1000 g/mol.

Technology for (Green) Environment!

Membrane separation performs on the principle of selective gas permeation. When gas mixture is introduced to the membrane, gas component dissolves into membrane material and diffuses through the membrane material. Solubility and diffusivity are different from gas component. Carbon dioxide, water vapor and hydrogen sulfide are easy permeable gas components, while methane, ethane and other hydrocarbons are very slow to permeate. This is why water and sour gas components in the natural gas are removed with the membrane. The driving force of gas separation is partial pressure difference of specific gas component between both sides of membrane.

Several membranes with different characteristics may be required to separate high-purity CO2. Solvent assisted membranes are being developed to combine the best features of membranes and solvent scrubbing. Much development is required before membranes could be used on a large scale for capture in power stations ration

We are now in the process of developing membranes with the important features such as longevity, compact/simple, applicable to CO2-rich gas, removal of H2O and H2S, excellent selectivity. The potential applications include: Natural gas treatment, CO2 for EOR (Enhanced Oil Recovery) injection, Integration with absorption process, Debottleneck an existing absorption plant, Landfill gas/Biogas upgrading, etc.

Carbon capture and storage, or CCS

We are developing a custom-built system to trial new hollow fiber membranes for capturing carbon dioxide from various sources such as power stations. The new membranes are highly selective for carbon dioxide in the lab. The trials are an important step in developing effective membranes for industrial scale use, which is in progress.

Hollow fibre membrane modules contain hundreds of tiny tubes which maximize contact between the gas and the membrane surfaces. Flue gas passes across the outside of the tubes but only carbon dioxide passes through to the inside. Currently carbon dioxide is separated from flue gas using volatile liquid solvents, which are bulky and have a significant energy cost. Hollow fiber membranes have the potential to substantially reduce the

energy required to capture carbon dioxide, while having a smaller environmental and physical footprint than existing solvent systems.

We are developing innovative carbon capture systems since last year. The trials are the latest in a long line of capture technology trials using real power station flue gas, including environmentally friendly solvents, several types of new membranes and adsorbent systems.

Carbon capture and storage, or CCS, is currently the only technology that can deal with the very large quantity of CO2 emissions from fossil fuel combustion and is a vital part of the lowest cost pathway to meeting global 2050 emission reduction targets.

Why We Do?

The excellent mass-transfer properties conferred by the hollow fiber configuration soon led to numerous commercial applications in various field such as the medical field (blood fractionation), water reclamation (purification and desalination), gas separation (Carbon Capture and Storage), azeotropic mixture separation (using pervaporation). Others application of this type of membrane are in various stage of development, e.g. and the biochemical industry (bioseparation and bioreactor) and hydrocarbon separation (by pervaporation). Due to the high technology of this advanced materials, GRT focuses more in the research of this materials as it has showed its distinguish performance in various field and applications compared to the conventional technique.

Technology for Green-Environment!

Renewable is abundant at no cost and carbon neutral. However, the biggest challenge has been the absence of efficient high energy density storage system. Any unused renewable energy is lost if not used immediately. A reliable storage system is thus undeniably required to convert a high percentage of renewable energy for a choice of applications or into the power grid. Therefore, hybrid between the renewable and the storage system is of a good choice for the generation and utilization of green energy for commercial/ industrial and residential applications. The low energy density storage has been in use for several domestic applications but with numerous hybrid units at the expense of high cost, huge space and poor cycleability (< 2000 cycles). This poses challenges and calls for solutions at unique scales such as high energy density storage, affordable cost, which would redefine energy industries. Therefore, the high energy density storage system becomes a sensible option for several applications, but not limited to: 1) Renewable resources (for instance: solar and wind) integration, 2) Power and Energy management, 3) Domestic Applications (in place of UPS, Diesel Generators, etc)

A flow battery is an electrochemical method of storing energy, meaning that energy is stored by chemical changes in an electrolyte solution that contain one or more dissolved electro active species. This solution is pumped through a fuel cell to either electrically discharge or charge the system. The typical proton exchange membrane fuel cell converts the chemical energy to electrical by dissociating the protons and electrons from the electrolyte solution. The protons move through the existing membrane while the electrons travel along an external circuit, which then supplies power.

The significance of the flow battery (rechargeable fuel cell) is that the energy and the power are controlled independently; thus, the storage limit can be extendable. The principle of redox flow battery is not only to convert chemical to electrical energy and but to store the energy internally which can then be utilized without self-discharge for many applications.
