SRRP · A disruptive pre-assembled Self-Regenerating solvent Recovery Plant based on the vapor recompression principle in order to diminish the emission of volatile organic compounds to environment.

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.
