ARBOK solution
ARBOK-LLS is a molecular-level separation technology for liquid homogeneous mixtures that enables extraction of ethanol from water–ethanol solutions at near-total purity, meeting or exceeding pharmaceutical-grade standards, without bulk heating or boiling of the mixture. It is designed to replace or supplement classical rectification in applications where maximum purity and energy efficiency are critical. The representative and industrially important case is the ethanol (C₂H₅OH) / water (H₂O) system, with initial ethanol concentrations ranging from 5% to 96% vol. ARBOK-LLS is not an optimization of distillation: it is a non-equilibrium, surface-controlled separation process that bypasses the thermodynamic limits of boiling-based systems and delivers higher purity at fundamentally lower energy cost. Rectification heats the entire system; ARBOK-LLS works only where separation actually happens.
A graphene-containing nanocarbon powder, engineered for selective surface activity, is applied to the free surface of the water–ethanol mixture. The powder surface is activated by pulsed electromagnetic radiation tuned to promote selective evaporation. Under these conditions only ethanol molecules undergo selective surface evaporation. Key physical features: evaporation occurs from the nanomaterial surface, not from the liquid bulk; water molecules are not involved in the phase transition; the bulk liquid stays close to its starting, ambient temperature throughout, with only a negligible rise. No membranes, vacuum columns, distillation trays, or chemical additives are used. Energy input is localized exclusively to nanomaterial activation rather than bulk liquid heating.
Market and application
The addressable market spans chemical synthesis and solvents, pharmaceutical-grade ethanol, electronics and semiconductor processing, specialty fuels and reagents, and premium alcohol production, where purity above what standard rectification can deliver commands a meaningful price premium. Because the process also cuts energy cost relative to classical rectification, it is additionally attractive to producers facing rising energy prices or emissions constraints on thermal separation. Market potential scales with global demand for high-purity ethanol and solvents across pharmaceutical, electronics, and premium beverage sectors.
CAPEX and OPEX are not tracked as fixed figures for this technology — they are calculated individually for each deployment site, reflecting local feedstock composition, throughput requirements, and energy pricing.
Use cases
Chemical synthesis and solvents; pharmaceutical-grade ethanol; electronics and semiconductor processing; specialty fuels and reagents; premium alcohol production; high-purity ethanol packaging and logistics.
Scalable from laboratory units (0.5–5 L/h) through pilot scale (50–500 L/h) to industrial modules (5–50 m³/day per module), with linear scale-up via modular replication. Supports continuous 24/7 operation. Nanocarbon powder replaced periodically, not continuously.
ARBOK-LLS can be deployed as a standalone polishing step downstream of existing distillation trains, or as a full replacement for the final purification stage in an ethanol production line. It integrates with standard vapor collection, condensation, and process-control instrumentation already used in ethanol and fine-chemical purification facilities, allowing incremental adoption alongside conventional rectification equipment.

Graphene-containing nanocarbon powder layer on the free liquid surface; pulsed electromagnetic activation source with controlled frequency and duty cycle; vapor collection and condensation of the ethanol product; residual water stream outlet. No membranes, vacuum columns, distillation trays, or chemical additives. Modular replication provides linear scale-up.
Near-total ethanol purity at or above pharmaceutical-grade standards, with minimal water carryover and very high molecular selectivity for ethanol over water, at atmospheric pressure and with no detected thermal degradation of the product. Energy consumption is substantially lower than classical rectification because heating is localized to the nanomaterial rather than the bulk liquid. Nanocarbon powder is non-toxic, chemically inert, has a long operational lifetime with a low degradation rate, and is not continuously consumed — replacement is periodic rather than continuous. The separated water stream remains physically and chemically stable and can be reused or discharged without additional treatment. Supports continuous 24/7 operation with stable performance.

Concept validated through laboratory-scale demonstration of selective surface evaporation, with purity, energy and lifetime performance characterized as described in Section 5. Remaining steps toward full commercial readiness include scale-up from laboratory throughput to industrial modules, extended continuous-operation trials, and third-party validation of energy savings across a broader range of feed concentrations.

Nanocarbon material supply and manufacturing consistency at industrial scale remain unproven beyond pilot volumes. Regulatory and food- or pharma-grade certification requirements for a novel separation method may extend qualification timelines. Customer adoption in a process industry accustomed to rectification may be slow, requiring extensive side-by-side validation against incumbent equipment. Scale-up from pilot to full industrial modules carries the engineering and cost risk typical of first-of-kind separation equipment.
