Biomethane flare NOXmatic BM

Gas flares by onedrop

Modern and large biogas systems for biogas upgrading to natural gas quality is becoming more popular. Here the biogas is treated for the complete removal of all unwanted gaseous materials and fed into the gas network or alternatively used as fuel in vehicles.

Here the technical requirements of the gas flare become even more critical, as the flare is now not only to be suitable for use with pure biogas, but also must be compatible with biomethane with a methane content of > 95%.

This is no problem for our modern NOXmatic BM flare for biogas and biomethane. With flexible burner technology we can combust both materials safely, efficiently and with low emissions.

The broad range of accessories for the NOXmatic standard flare is also available to our customers. With this offering we are able to meet all the individual requirements of our customers and their applications.

NOXmatic / NOXtreme CDM

Gas flares by onedrop

Since the implementation of the Kyoto treaty in February 2005 the world has seen a widespread development and tightening of regulations governing greenhouse emissions. The Kyoto treaty has provided an incentive for industrialized and developing nations alike to invest in the reduction of emissions.
To get the required CO2 – certificates out of JI- and CDM projects it is necessary not only to ensure the correct and sustainable treatment of the methane gas according to local regulations, but also to reliably collect and save the data in a manner which inhibits any possible manipulation.
ennox delivers the required gas scrubbers, pressure stations, flare and additional measurement and recording components for your JI/CDM- project.

Landfill gas cleaning and safe incineration

Gas flares by onedrop

Every year, millions of tons of household garbage and other refuse are deposited in landfills around the world. Biochemical decomposition processes of organic bonds in these landfills produce up to 150 – 250 m³ of landfill gases per tonne of household garbage.

Due to a methane content of up to 60%, landfill gas ranks number six on the list of climate-disrupting methane producers worldwide, but it is also an important source of energy with enormous potential if used sensibly.

Up to a content level of approximately 40% methane, landfill gas may still be recovered usefully in modern block heating plants. The important factor in this case is an effective and project-specific pre-cleaning process for the gas.

High temperature flare NOXtreme

Gas flares by onedrop

High temperature combustion in gas flares is required when specific combustion parameters must be adhered to (TA Luft, governmental or local regulations) for reasons pertaining to the environment. One such parameter includes, but is not limited to, the emission of carbon dioxide (CO2) or nitrogen oxide (NOX).

With special burner technology and a suitable combustion chamber suitable for temperatures > 1000°C, the ennox high temperature flare provides for and controls the correct combustion temperature. Our flares are designed to satisfy even the most demanding applications.
At the heart of the NOXtreme flare control is the fully automatic control from the NOXmatic unit, which, if required can be extended to meet the actual project demands.

The temperature control of the combustion process can be achieved either with a manual or automatic combustion air regulator.

Automatic gas flare NOXmatic / NOXmatic NANO

Gas flares by onedrop

Our core business is the most up-to-date quality gas flare technology for a safe, efficient and environmentally friendly combustion of gases from landfill, bio and sewage gas systems.

Our fully automatic flare NOXmatic with its extensive range of accessories can be suited for every low and medium temperature combustion application. With various burner systems we can cover the complete spectrum of power requirements in single or multi-stage operation.

The NOXmatic flare is manufactured entirely from stainless steel and equipped with high quality components (i.e., ATEX certified flame arresters, DVGW certified automatic and manual valves…).

All control and monitoring functions are achieved with an individual programmable controller, which also governs the signal transfer with the main controller.

NOXmatic flares can be delivered worldwide with a capacity from 100kW to 20MW.

Manual gas flare ECO

Gas flares by onedrop

The robust and maintenance free flare suitable for small biogas systems, special installations or when an automatic gas flare is not specified.

The ECO flare is manufactured entirely from stainless steel and equipped with high quality components (i.e., ATEX certified flashback prevention, DVGW certified manual flap…).

Ignition of the electrode is carried out with the simple press of a button located in the control cabinet.

The complete equipment for automatic operation is available for easy retrofit. An ignition system rated for 12VDC is available upon request.

Pressure increase blower RAV

Gas storage by onedrop

We supply our customers with radial ventilators for the increase in system pressure in biogas operations, either as an individual unit or as a complete blower station with all internal pipework and instrumentation. The ventilators can be either directly driven or with equipped with a belt drive. They are suitable for ATEX zone 1. The flowrate can be infinitely adjusted by using an optional frequency inverter. The radial ventilators are suitable for flowrates up to 2000 m3/h and a pressure increase up to 160 mbar (or 320 mbar with a multi-phase system).

Double membrane gasholder NOXstore DM

Gas storage by onedrop

For temporary buffering due to fluctuations in gas production or inoperable production systems or consumers a storage of the produced biogas is required.
The holder is made up of two spherical shaped polymer membranes (other forms are also possible), lying one inside the other. The external membrane is maintained in a stable form with the use of an air blower. The external membrane then serves as protector for the inner membrane against the influence of environmental factors such as wind or snow.
The gas is stored within the inner membrane. The pressure generated by the blower is applied to the outside surface of the inner membrane, thus, maintaining the system pressure from the biogas reactor. The movement of the inner membrane during inflation and deflation is recorded either with a cabled sensor or radar. The information is then converted into a level indication signal and sent to a central control system.
The regulation of the supporting air resulting in the stability of the external membrane is controlled by a standard pressure maintaining valve. A special over pressure valve is responsible for the safety within the inner membrane.

Low pressure gasholder NOXstore

Gas storage by onedrop

For temporary buffering due to fluctuations in gas production or inoperable production systems or consumers, a storage of the produced biogas is required.
ennox has developed the NOXstore gas holding system for the zero pressure or fluctuating pressure storage of biogas from the digester.
The storage of the biogas/sewage gas is made in a cylindrical gas bag which is freely hung in a building or silo. The silo serves in this case as an effective supporting and protective construction.
The storage systems are designed according to the latest governing international standards and regulations i.e., DWGW, ÖWAV, DWA, SUWA, safety regulations for biogas systems.
The gas bag is manufactured from a high quality polyester membrane (non-flammable, fungus repellant and methane/UV resistant) utilizing the most modern frequency welding techniques.
ennox offers not only the design, construction and installation of the gas storage system, but also the subsequent ongoing inspection and maintenance of the system by fully qualified and authorized personnel.

Sediment trap SET

Gas treatment by onedrop

Fine sediment and foam particles in the saturated biogas originating directly from the digestion can make it´s way into the pipework system. In order to eliminate sediment accumulation in the pipework an ennox sediment trap can be used.

The trap is installed after the reactor directly in the pipework. With a special nozzle at the trap inlet the saturated and contaminated gas is set into a spiral motion. The particulate matter separates from the gas on the side walls and passed into the collection point with the extracted water vapour.

Discharge is carried out with a siphon. Additionally a spray and control connection can also be installed.
