Renewable fuels
The renewable fuels sector encompasses a wide range of processes
The renewable fuels sector encompasses a wide range of processes, from biogas plants and combined heat and power to waste incineration and power generation with gas turbines. These processes place high demands on process control: gas streams must be cleaned or cooled, humidity often needs to be precisely regulated, and the efficiency of power generation is under constant pressure. Without the right technology, this can lead to loss of efficiency, higher maintenance costs, or problems with emissions and regulatory compliance.
Spraybest supports companies in the renewable fuels sector with solutions for gas scrubbing, gas cooling, air humidification, and inlet air cooling. We think along with you about the right spray, misting, and separation technology for your installation. We work with renowned brands such as BETE, Munters, and RVT. These brands are well suited to applications where spray technology, mist elimination, and column technology play a central role in power generation. Whether it concerns a small-scale biogas plant or a large-scale power plant, we look together at the process conditions, the available space, and the desired result, so that the chosen solution truly fits your installation.
Gas scrubbing for cleaner gas streams
The generation of renewable fuels, for example from biogas or through combustion processes, produces gas streams that may contain contaminants such as dust particles, acidic components, or other unwanted substances. Gas scrubbers are used to remove these contaminants from the gas stream by bringing it into contact with a scrubbing liquid. A well-functioning gas scrubber contributes to lower emissions, more stable process operation, and less wear on installation components further down the process.
The effectiveness of gas scrubbing depends heavily on the contact between gas and liquid: the better the scrubbing liquid is distributed, the larger the contact surface and the more efficiently contaminants can be captured. BETE supplies nozzles that distribute the scrubbing liquid evenly over the contact surface, which is essential for an efficient gas scrubber. In packed columns, for example, axial swirl nozzles ensure even distribution over the packing surface, so that no gas flows through the packing untreated. RVT supplies column internals that optimize flow, distribution, and mass transfer within these columns. Munters contributes with mist eliminators that effectively separate any liquid droplets from the cleaned gas stream, preventing liquid loss and contamination further down the process.
Gas cooling for safe and efficient processes
Gas streams in the renewable fuels sector can reach very high temperatures, for example during combustion processes or the treatment of flue gases. If these gases are not cooled in time, this can damage installations or disrupt processes further down the chain. In evaporative gas cooling, also known as quenching, water mist is injected into the hot gas. The water evaporates, drawing energy from the gas, which cools it rapidly.
The finer the water is atomized, the greater the surface area of the droplets and the faster the evaporation, and therefore the cooling. BETE supplies nozzles designed to achieve this fine atomization, even under high temperatures and demanding process conditions such as corrosive gas streams. By combining nozzles and spray lances, gas cooling can be precisely tailored to the desired temperature range, the available flow rate, and the space within the installation, helping to prevent equipment damage and unplanned downtime.
Air humidification for optimal process conditions
Within renewable fuels installations, humidity often affects the efficiency and reliability of the process. Air that is too dry, for example, can lead to increased sensitivity to dust or static electricity, while correct humidity contributes to more stable process conditions and less equipment failure. Air humidification ensures that the amount of water vapor in the air is increased to the desired level.
BETE offers mist and fog nozzles that are highly suited to air humidification. By atomizing water into very fine droplets using liquid pressure or compressed air, these droplets evaporate quickly in the air, increasing relative humidity without creating wet surfaces. This way, humidity can be precisely tailored to the requirements of your process, contributing to more stable operation of your installation.
Inlet cooling for more efficient power generation
A specific and valuable application within the renewable fuels sector is inlet cooling of gas turbines, also known as Turbine Inlet Air Cooling. Warm air is less dense than cold air, which means the capacity of a gas turbine can decrease significantly at high temperatures — precisely at moments when demand for electricity is high, such as during hot summer days. By cooling the turbine's inlet air through evaporation, air density increases and the turbine can perform closer to its rated capacity again.
BETE supplies air cooling misting nozzles specifically designed to produce very fine droplets at high pressure differentials. This is essential for inlet cooling: the droplets must fully evaporate before coming into contact with the turbine blades, to prevent damage or erosion to the installation. Our misting nozzles are suited to the most demanding conditions, offering an effective and economical alternative to electric chillers.
