BioGas Generation
Erivac provides equipment for BioGas Generation
All over the world governments and companies are looking for ways to become more sustainable and reduce our carbon footprint in order to meet global warming targets. There is a change of paradigms in a process where fossil fuels, such as “Natural” Gas, are being phased out in favor of BioFuels. There is a huge potential in processing organic wastes, such as: – industrial and municipal sewage with high organic load – livestock manure; – sludge from waste water treatment; – household waste, etc., in an anaerobic process to produce Biogas. This Biogas can and will substitute “Natural” Gas for industrial purposes, BioFuel for combustion engines, and, as in many places around Europe for example, household heating and cooking gas.
BioGas Generation
BioGas is produced using an anaerobic digestion process that normally has a thermal control for maximum efficiency, thus heating and cooling of sludge is necessary. Digested Sludge often need Hygenization/Sterilization. The resulting BioGas also needs treatment before it can be commercially available to reduce impurities such as hydrogen sulfide.
For these processes, the following process equipment can be very useful
Ejectors and Vacuum Systems
– Steam Jet Heater for Hygenization / Sterilization
– Eductors for Tank Mixing and Jet Aeration for Waste Water Treatment
Heat Exchangers
– Spiral Heat Exchangers for liquid/liquid applications with dirty or high viscous media or product slurries with high solid content as economizers, heaters / coolers,
– Welded Plate Heat Exchangers. These are for applications as above but for less dirty or semi-fouling media.
– Gasketed Plate Heat Exchangers
– Corrugated Tube In Tube Heat Exchangers – for liquid/liquid applications with dirty or high viscous media as economizers, heaters / coolers,
Filters
– Automatic Filters for protection of heat exchangers and spray nozzles for reduced maintenance necessity and increased plant availability, filtration of raw water and cooling water circuits. If Sea or Brackish Water is used, acting as effective mussels and mussel larvae stop.

Ejectors and Vacuum Systems
Steam Jet Heater for Hygenization / Sterilization
Jet Ejectors
Steam Jet Vacuum Ejectors
Steam Jet Heaters
Steam jet heaters provide direct steam heating by condensing steam into the liquid. This gives fast heat up, compact installation, and efficient heat transfer.
Thermocompressors
Jet and Venturi Scrubbers
Körting Jet Scrubber
A self priming jet scrubber used for cooling, absorption, dedusting, and gas conveying. Especially effective for removing dust with particles above 3 µm and can often replace mechanical ventilators by providing pressure gain.
Körting Venturi Scrubber
A compact scrubber mainly used for dedusting, ideal for very fine particles below 3 µm. Wet operation makes it suitable where dust is sticky, hygroscopic, or otherwise difficult to handle with dry filtration.
Vent Gas Treating System (VGTS)
A complete, skid style unit combining jet scrubber, separation tank, packed tower, and swirl droplet separator. Designed for demanding waste gas cleaning duties, for example removal of acids and other harmful components from hot process gas streams.
Eductors for Tank Mixing
Liquid Jet Mixing Nozzles (Eductors)
Core components in Körting tank mixing solutions for continuous or batch mixing. They can replace mechanical agitators and often deliver equal or better mixing results, with low energy input and no moving parts in the tank.
Tank Mixing Systems
Custom designed layouts where multiple eductors are positioned close to the tank bottom and wall to create guided circulation, prevent sedimentation, and avoid temperature layering across the full tank volume.
Jet Aeration for Waste Water Treatment
Jet Aerators (Körting ejectors)
Ejector based aeration that disperses air into fine bubbles and creates strong turbulence for high oxygen transfer, designed for polluted wastewater and low maintenance operation.
Multi path Jet Aerators (in tank units)
Compact manifold systems installed on the tank floor to deliver full tank mixing and comprehensive aeration, with layout adapted to tank geometry, depth, and oxygen demand.
Through the wall Jet Aerators
Stainless steel units mounted through the tank wall with external connections, built for high availability and optional shut off for nozzle checks without emptying the tank.
Jet Aerators for SBR plants
Arranged to provide both aeration and mixing with air on, plus selective circulation with air off during mixing phases, supporting alternating SBR operation.
Heat Exchangers
Spiral Heat Exchangers
Spiral Heat Exchanger Type 1, Liquid to Liquid
Designed for demanding duties with particle laden, fibrous, or fouling liquids. The single channel, self cleaning flow supports long service life and can replace up to three shell and tube exchangers.
Type 2, Condenser and Evaporator
Used for vacuum condensation, vent condensation, and evaporation, with very low pressure drop and easy access for cleaning. Can be mounted directly on columns or reactors to reduce installation cost.
Type 3, Steam Heater
For steam heating in duties with cyclic loads and high efficiency requirements. Built to handle large temperature and pressure swings, with low pressure drop during condensation and a self cleaning channel for contaminated steam.
Type 2 Column, Modular Spiral Exchanger
For large scale condensation inside industrial columns, built from multiple spiral exchangers welded in series within a common shell. Optimised for very high condensation loads with minimal pressure drop, including vacuum processes.
Sludge Heat Exchanger for Biogas Digestion and Energy Recovery
Typically used as an anaerobic sludge heater, raw or digested sludge economizer, pasteurizer, and for effluent energy recovery. Self cleaning turbulence helps handle fouling media with low maintenance and low pressure drop.
Welded Plate Heat Exchangers
GreenBox™ Model S
A welded plate heat exchanger with square corrugated plates welded into a core, with removable side panels for easy inspection and cleaning.
GreenBox™ Model W
A fully welded, non openable version designed for clean media at high temperatures and or pressures, built to minimize leakage risk.
GreenBox™ Model SP
A welded plate heat exchanger using flat studded plates to allow larger channel spacing, making it better suited for fouling or viscous media and more demanding materials.
Plate and Shell Heat Exchangers
Corrugated welded plate packs inserted in a cylindrical shell, available as welded in place or gasketed and removable for mechanical cleaning or replacement.
Gasketed Plate Heat Exchangers
Gasketed Plate Heat Exchangers
Individually stamped heat transfer plates with gaskets in a dedicated gasket groove, designed for tight sealing and high heat transfer in a compact footprint. Easy to open for cleaning and inspection, with modular scalability.
Double Wall Plate Heat Exchangers
Two plate layers between hot and cold fluids create an extra safety barrier and enable visible leak detection, reducing cross contamination risk in sensitive applications.
Semi welded Plate Heat Exchangers
Hybrid construction combining welded and gasketed plates, giving a secure barrier for one media while keeping the other side service friendly for maintenance and cleaning.
