 Project objective

The amount of volatile organic compounds (VOC) emission exceeds 15 MT/year in the world and 4 MT/year in Europe. These discharges constitute enormous environmental pollution and lead to serious health problems, such as respiratory insufficiency and asthma. Most of these emissions are caused by solvent-laden streams by companies in the packaging, chemical, degreasing and printing sectors. Solvent Recovery is a well-known technology that, although it has been extensively used by big companies within Oil & Gas from 1980, it is neither cost-effective nor adapted to small projects due to its intrinsic nature, requiring a boiler and a cooling system. As a consequence, thousands of tons of solvents, worth close to 1€/kg, are lost by SMEs within these markets and are discharged in polluted streams of air and water. SITES here proposes Self-Regenerating Recovery Plant (SRRP), a new technology able to generate steam without boiler and reject heat without cooling system, achieving the same effect in a more compact cost-effective installation. It absolutely adapts the system to SME main requirements, solving the following issues: • Cost: 85% reduction from 4.5 M€ to 0.65 M€ • Construction time: from 1 year to 2 days • Footprint: only 24m x 4m against the previous 50mx50m • Energy consumption: down to 1 kWh per kg of solvent instead of 2 kWh/kg • Minimum capacity: as low as 5,000 Nm3/h vs previous 30,000 Nm3/h • Safety: avoiding problematic operation by reducing regeneration temperature • O&M: simplifying it by deletion of boiler and cooling tower Additionally, global society shall be positively impacted because of the following points: • Save of 6281 tonnes/year GHG emissions • Avoidance of 4536 tons emission of VOC Solvents per installation • Save of 24.500 kg/h of water per average installation All in all, we intend to launch the product in 2021, achieving accumulated profits worth 5.95 M€, a ROI of 3.25 and creating 20 new jobs all within 5 years.
