Status of dryer after revamping SHS-MVR-1S-25 pr
Energieffektiv termisk separasjon innenfor biomarin industri AGENDA Energi forbruk i ”state of the art” MVR inndampere EPCOVAP-MVR, standardisert kompakt MVR inndamper MVR fallstrøms inndampere, med ”case studies” fra biomarin industri Nyutviklet overhetet damp tørke med MVR EPCON testanlegg Evaporation Evaporation is a boiling process for dividing a liquid feed with low DS in a very pure condensate and a liquid concentrate with high DS. If not using MVR energy system, evaporation require big amount of thermal energy supply and cooling water. THERMAL ENERGY FROM BOILER COOLING WATER LIQUID FLOW (low DS) CONDENSATE LIQUID CONCENTRATE (high DS) MVR - Principle and energy saving PROCESS VAPOR EL. ENERGY SUPPLY The compressed vapor is used as energy source in the evaporator. 800 Energy consumption kWh/t evaporated The vapor evaporating is compressed by a MVR fan by use of small amount of electrical energy. Comparision of energy systems in evaporation processes. 700 600 MVR vs direct steam give 93 to >98% energy saving 500 400 300 200 100 LIQUID FLOW (low DS) CONDENSATE LIQUID CONCENTRATE (high DS) 0 Direct steam 2 effect 2 effect TVR MVR EPCOVAP-MVR Standardized evaporator Key characteristics Capacity: <200 - 2500 kg/h condensate Temperature: 30 - 100°C Energy cons.: 15 - 50 kWh/ton cond.

Feed tank 5-10% solids Product 60% solids Applications: Concentration of hydrolyzed fish extracts. Concentration of crab and mussel extract. Concentration of extracts from krill and shrimps. Concentration of algae extracts. Concentration of stick water. Dewatering of wastewater from bio marine industry. MVR Falling Film Evaporator Key characteristics Capacity: 2 – 100 tons/h condensate Temperature: 30 – 100°C Energy cons. : 10 - 25 kWh/ton cond. Designed to be suitable for a variety of applications MVR falling film evaporator Application: Biomarine industry Liquid: Hydrolyzed salmon protein extract •Evaporation capacity 5.500 kg/h •Energy consumption 20 kWh/ton condensate •Concentrate approx. 55% DS MVR falling film evaporator Application: Biomarine industry Liquid: Algae extract •Evaporation capacity 2.500 kg/h •Energy consumption 15 kWh/ton condensate •Concentrate approx. 30% DS MVR falling film evaporator Application: Biomarine industry, Liquid: Stick water •Evaporation capacity 30.000 kg/h •Energy consumption 25 kWh/ton cond. •Concentrate approx. 35% DS Overhetet damp tørke med MVR De viktigste fordelene: Fleksibel mht produkt inn – væske, filterkake, etc. Lavt energi- og kjølevanns forbruk Ikke kontakt mellom produkt og luft Ingen utslipp av forurenset tørkeluft Ingen fare for brann og eksplosjon God kontroll på bakteriologisk kvalitet 1200 Energy consumption kWh/t condensate SHS-MVR tørken er nylig utviklet, og per i dag utprøvd og verifisert på mineral produkter. Andre anvendelser må verifiseres når ny pilot-tørke blir etablert (innledende tester på egnede væsker er også mulig idag). Tørking av bio-marine avfalls fraksjoner/ slam er en mulig anvendelse.
