Compressors and systems
Compressors and systems Biomethane as a fuel operation, the compressor module delivers 8640 kg of biomethane in a 24-hour period. Integrated filter and post-drying cartridges installed on the high-pressure side clean the compressed gas and remove residual moisture from it. As in most applications, the storage is used here as a 3-bank system consisting of three individual sub-storages, the high, medium and Fig. 5: B3360 Storage module low banks. This division allows an optimum utilization rate. Thanks to the larger quantity of gas available, ve hicle refuelling can be carried out in immediate succession. The filling and refuelling control regulates the priority filling of the Fig. 6: Priority order monitoring control (VRÜ) high-pressure accumulator and the sequential gas withdrawal from the high-pressure accumulator. It is possible to control one or more filling lines. The dispensing device can be designed with a flow measuring device (display of the dispensed refuelling quantity in kg or m³) as well as a display field with the indication of the specific gas price as well as the total price in the desired currency. The filling and refuelling control system regulates the filling process and thus ensures economical refueling with short filling times at the same time. For the operation of a public service station, the use of a fuel dispenser is required by law. The display shows both the unit price, the quantity refuelled and the final price at the same time. The dispensers are available with one or two hoses and with one or two devices for mass flow measurement. This allows either separate or simultaneous vehicle refuelling on both sides of the dispenser. With an automatic fuel dispenser, it is possible to realize an accounting of the fuel data without a manned cashier's store. With regard to operation, the different fuel dispenser models can be optionally tailored to fleet card operation and/or credit card operation. All of the company’s large systems offer interfaces for optional connection to an Internetcapable PC or cell phone. This allows the operator to monitor the operating status remotely around the clock. Comprehensive and seamless project management – a core competence According to customer specifications and in close consultation, BAUER project engineers first select the best location for the filling station. Special focus is placed on exact compliance with applicable legal regulations. By minimizing explosion protection zones and tailoring the size of the refuelling systems, the supplier is able to find an optimal solution for installation even in difficult space conditions. After installation, the complete piping of the sys- Fig. 7: Dispenser unit with billing system tem including all pressure lines from the compressor to the storage tank and further to the dispensing point or dispenser is carried out according to the relevant guidelines. This is followed by an inspection by an approved acceptance organization, such as the TÜV. The project team coordinates the necessary scheduling with the companies and authorities involved. Service technicians carry out the electrical wiring of both the compressor unit and the dispenser/dispenser in accordance with the agreed plans. Only a high-voltage connection must be provided by the operator. After installation, the compressor unit is booted for the first time and thoroughly checked again. The supplier takes over the entire project organization. It ranges from the installation and commissioning of the compressor storage unit and the dispenser technology to the precise coordination of deadlines. As a result, commissioning can usually take place after just a few days. After a successful assembly at the installation site, the installation is inspected by an expert. This acceptance at the installation site is also carried out by the service team together with the respective supervisory authority. The comprehensive service also includes detailed instruction of authorized 26 GREEN EFFICIENT TECHNOLOGIES 2022
Compressors and systems Biomethane as a fuel persons of the client in the technology and electrics of the system so that the operator of the system can carry out basic settings and simple maintenance work independently. On request, seamless monitoring of the compressor unit is offered in conjunction with a 24 h service and after-sales. Changes in settings or adjustments can then be made around the clock online via the Internet or via a mobile phone connection. Status reports on operating hours and sales of gas volumes sold can be transmitted via SMS or e-mail, as can maintenance requests or fault reports. Biomethane injection – Munichbased company supplies the technology In addition to filling stations, the compressor manufacturer from Munich has also developed special compressor systems for the area of biomethane production based on its many years of expertise and has successfully established them on the market. Among other things, they are used for seasonal compensation of transport fluctuations and network overloads: In case of overload of a low-pressure pipeline, e. g. due to increased biomethane feed-in, the excess natural gas-biomethane mixture can be fed into a higher-quality network. In this way, existing buffer volumes in highpressure transport networks are better utilized. Biomethane is fed into a natural gas network in different network types with pressure ratings from PN10 to max. PN100. Shaping the future today: Climateneutral mobility with hydrogen! Based on its sustainability-oriented corporate philosophy, the company stands uncompromisingly for climate-friendly mobility concepts. For this reason, the technology-leading mechanical engineering group and member of the Center Hydrogen.Bavaria (H 2 .B), is consistently supporting the broad establishment of this energy carrier of the future with a recently launched development offensive for H 2 filling station systems.
