THE PERFECT SOLUTION FOR EVERY CHALLENGE.

WHICH VOLUME DO I CHOOSE?

Storage tanks are designed to compensate for fluctuations in production and consumption, for volume changes due to varyingtemperatures and for stagnating consumption; furthermore, gas holders store gas for later use. With these parameters theoptimal dimensioning can be determined. The ideal storage volume varies according to the plant design, the substrate mixture,and the management of the plant.

BASE LOAD OPERATION

The goal is to enable consumers to operate at high capacity. Consumers’ performance should neither be influenced nor determinedby fluctuating gas production but should constantly operate at a defined load. Flaring excess gas should be avoided.Therefore, excess gas production is buffer stored and lack of gas production is replaced by the stored gas to cover the demand.Conventional storage tanks hold volumes corresponding to a gas production of three to four hours.

PEAK LOAD IN FLEX MODE

The storage tank serves to balance out the continuous gas production and the discontinuous consumption. Low gas productionwill be stored over a long period of time, followed by a short but high-powered consumption period. That is why bigger storagetanks are required.

Storage fill level

WHICH PRESSURE DO I CHOOSE?

The operating pressure is predetermined by the plant design and the dimensioning of the various components. We are tal-king about low-pressure systems, starting from zero pressure to 50 mbar. The operating pressure influences the dimensio-ning of the entire gas line. Among them are: gas ducts, safety devices for protection against over-pressure, condensate traps, flares, devices for gas purification, and gas pressure intensifiers.

WHICH EXTERNAL LOADS DOES ASTORAGE TANK HAVE TO WITHSTAND?

Depending on its location, wind load, temperature and sun radi-ation all have an impact on the gas holder. The impact of snow loads depends both on the location and operating conditions since waste heat from the digester results in de-icing in regular operation. When not in operation, the digester does not produce any waste heat. In this case the full snow load must be taken into account.

UP TO WHICH TANK DIAMETER DO WE BUILD GAS STORAGE TANKS?

Textile gas storage tanks and coverings can be built to very large dimensions. The tank diameter basically does not pose any limitation as to the choice of a suitable gas storage tank.

WHICH KIND OF AGITATOR TECHNOLOGY CAN BE USED?

There is a suitable storage system for each type of stirring device. Submersible mixers are accessible via service manho-les or service shafts in the membrane. It is not necessary to remove membranes for service purposes.

WHICH COSTS DO I HAVE TO TAKE INTO ACCOUNT?

In terms of economic evaluation of a storage system, not only the initial investment and the running costs play a major role, but also the replacement investment and opportunity costs are to be considered. Opportunity costs arise from lesser yields in power and heat generation and from a higher use of substrate in less suitable storage systems. The highest costs arise when the CHP (combined heat & power) does not operate at full capacity. These opportunity costs can exceed the initial costs of the biogas storage tank after only a few years of operation.

DOUBLE MEMBRANEGAS STORAGEFREESTANDINGThe freestanding double membrane gas holder consists of a formative outer membrane and of an internal and a bottom membrane forming the actual gas space. A permanently running support air blower provides air to the space between the membranes to keep the pressure constant – balancing a possible inflow or outflow of gas. The pressurized air keeps the outer membrane in shape and allows the gas holder to with-stand external loads. At the same time, the inner membrane is put under pressure and gas is pushed into the gas ducts.

A widely visible trademark of the Sattler double membranegas holder is the patented AIRFLOW-SYSTEMTM. It ensures a uniform air intake across the height of the gas holder. Laser measurement is preferably used to determine the filling level inside the tank. To improve measurement accuracy, the inner membrane is manufactured as to ensure reproducible membrane movement.

DOUBLE MEMBRANE GAS STORAGE TANK-MOUNTED

• High operating pressures

• High volumes up to a hemispherical shape



• Low investment and running costs

• Short construction time


• Uniform air intake via the AIRFLOW-SYSTEMTM

• Various fittings possible

FEATURES:

The tank-mounted double membrane gas holder consists of an outer membrane and an inner membrane that seals the fer-mentation space gas-tight. The outer membrane is reinforced by a support air blower. This is to maintain the internal pressure at a constant level and to ensure to withstand wind and other outer forces (loads).

Much like the freestanding DMGS this gas holder type also uses the patented AIRLFOW-SYSTEMTM. Both membranes are anchored to the crown or to the outer wall of the steel or con-crete tank using clamping rails with a positive and non-positive fitting. The positive fitting is secured by a rope welded into the outer rim of the membrane.

The substructure prevents the inner membrane from touching the substrate and being destroyed by the agitators. The belt- structure and central pole are designed to withstand the re-quired loads. Filling levels are measured by means of hydraulic measurement systems. Various openings ensure the perfect operation and servicing.

MOBILE GAS STORAGE FOR RENT

During repair or modification works at the gas storage plants, there is often the need for a temporary option for the storage of biogas.

The lack of a temporary storage alternative leads to limitations in the flexibility of the plant and is also related to inevitable major financial losses. Moreover, lacking a temporary reliable storage system entails the risk of biogas or methane release taking place, an issue that should not take place and not only for ecological reasons.

Sattler CENO‘s mobile gas storage for rent is designed as a horizontal double membrane gas storage. It offers operational safety at the plant and allows the operation of a cogene-ration plant also during inspections or modifications of the gas storages.

Compact. For rent. Safe.

EThe single-shell tank-top biogas roof consists of an outer membrane resting on a central pillar. This allows the biogas roof to withstand external forces, such as snow, rain, wind loads etc. The biaxial curvature of the surface prevents the roof from fluttering and pumping in the wind. The membrane is fastened to the top of steel or concrete tanks in order to form a gas-tight sealing. Safety valves secure the covering against over- or underpressure on the gas side. The double-shell biogas roof is a mast-supported tank cover consisting of an inner membrane forming the actual gas space. Similar to a tent, the outer membrane is stretched between the central pillar and the outer edge of the tank. This ensures an even pretension of the membrane and a reduced wear and tear around the edge of the tank.

The tank-top silo roof helps prevent emissions and the contamination of fer-mentation residues with rainwater. It offers the ideal solution for low-emis-sion tank coverings. The roof has been designed to withstand extreme wind loads as well as snow and water loads. Its material-specific design has led to a characteristic shape. It prevents the roof from fluttering and pumping with the wind while also reducing material fatigue. Due to the very low level of emissions, it is also a great contribution to a cleaner environment.

The silo roof is distinguished by a highly sophisticated multi-functional design, which makes it the ideal solution for agriculture and for sewage treatment as well as biogas plants.

SILAGE LAGOONS FOR BEET PULP

• Good value, low-cost solution

• High filling volumes

• Permanently liquid-tight

• Low-emission

• Easy building permit application

• Stable fermentation process

• Reduced labour

• No mildew

• Complete emptying of lagoon

• Catching and recycling of rainwater

FEATURES:

Silage lagoons are a low-cost solution for storing substrates and fermentation residues. They are highly customi-zable to meet all kinds of location requirements, both in terms of size, shape, and operation of the lagoon. When it comes to ensuring even lower emission levels, our tested and proved floating covers should be used. Moreover, the silage lagoon is equipped with an integrated high-volume gas holder upon request. They function as a post-fermen-ter and/or fermentation residue storage tank both in the construction of new and in the re-equipment of existing lagoons. Special service and operating platforms ensure an optimal management of the lagoon.

We have been specialising in slurry silage lagoons for over two decades and are certified according to JGS since 2002. Due to the high quality of our materials and up-to-date manufacturing and welding processes, we have meanwhile hundreds of silage lagoons in operation to the fullest satisfaction of our customers.

A special form of silage lagoons in our portfolio is dedicated to the storage of beet pulp. In these lagoons the sto-red substrate consists of crushed beetroot. The special design of the PE sealing foils allows for an ideal withdrawal of the substrate at a predefined station. To achieve this Sattler CENO designed a special pump trolley, which may be moved across the dam of the silage lagoon and immerged in the substrate. The pump is mounted on the trolley to ensure the automatic inflow and outflow of gas from and to fermenter tanks.
