Wastewater Treatment for the Bioenergy Industry

by HydroThane STP BV     based in KC `s Hertogenbosch, NETHERLANDS

The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.

Production of Biofuels from Microalgae

by AlgaEnergy, S.A.     based in Alcobendas, SPAIN

Production of biofuels from certain microalgae and cyanobacteria would appear to be the most promising alternative to current methods, since its yield is very high, sustainable, uses either wastewater, brackish or seawater, does not require the use of agricultural land, does not compete with human food and the cultivation process consumes the CO2noxious gas.

ALGAENERGY is responsibly paving the way towards making microalgal-based biofuels industrially profitable.  The R&D projects assigned to this task include work on selection and genetic engineering of different microalgae to produce substantial lipid-carriers, some of them patented, as well as the establishment of a suitable and scalable production process.

Sensor for Biogas

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Anaerobic Digestion plants produce various gas components from a source material (or feedstock) that can be composed either solely or as a mixture of slurries, purpose-grown crops, food and organic waste material. The composition of the gas produced varies depending upon the feedstock and the Anaerobic digestion process itself. As a consequence, it is normal to measure various components of the resultant gas produced to evaluate the efficiency of the Anaerobic Digestion process. Furthermore, due to the flammable nature of Methane (CH4), and the risk of asphyxiation, most plants feature ambient air monitoring to protect personnel from any unplanned accumulation of leaked gas. CH4 is the gas component fuel, which is the intended end product of the anaerobic digestion process. In biogas plants, the concentration of CH4 in a working plant varies between 50%-75%, which is well above the Upper Explosive Limit (UEL).

Biogas monitoring

Gas Sensing for Gasification

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Syngas (short for synthetic gas) can be burnt and used as a fuel source, the main constituents of syngas are Carbon Monoxide (CO) and Hydrogen (H), which amount for around 85% of Syngas, and it is produced by a process called Gasification. Gasification starts with a base material which can originate from a wide variety of materials for example wood chips and pellets, plastics, municipal solid waste, sewage, waste crops, and fossil fuels such as coal. During Gasification the base material is reacted at high temperature without combustion with controlled amounts of oxygen (O) or steam. The composition of the base material combined with the amount of oxygen and heat used in the process affects the composition of the resultant SynGas, in which the CO can vary between around 20 and 60%. In addition, large amounts of H and CO are also formed. The measurement of CO is therefore an important feature in the production of SynGas.

The Biotechnology market is ever changing and on the leading edge of technology changes.  New products are continuously under development and agitation and mixing is used throughout the process.   A process may require any or a combination of the following:  blending, solids handling including incorporation/dissolving/suspension, mass transfer, and solids and heat transfer.   The scale for Biotechnology reactors and support units range from a few liters to several cubic meters and from small laboratory units to large scale fermenters.   Biotechnology applications also require vendors who have strong R&D departments and laboratory facilities, polished and aseptic designs, easy drainability and cleanability designs, material validation, quality control programs specific to the project, and are able to meet governing specifications and directives such as FDA, USP, ASME-BPE, and cGMP requirements.

Evidence for claims of sustainability / responsible stewardship

by Ecometrica     based in London, UNITED KINGDOM

In many land intensive sectors, strict national, regional and global standards and regulations exist guiding how products must be produced. As pressures on land, biodiversity and communities in developing countries become stronger, ever tighter regulations will result. OE can be used to demonstrate compliance with any type of environmental regulation, for example in the areas of biofuels, timber, palm oil, forest protection, and water usage.

Industrial briquette presses for Biomass briquetting

by WEIMA     based in Ilsfeld, GERMANY

Harness the energy that’s inside your biomass! For too long, human and naturally produced substances have been disregarded. Straw, hay, tobacco, nutshells, miscanthus, pulse parings, cotton and flax are valuable resources for heat energy generation. The briquette shape makes your waste more cost effective to transport and ready in a saleable format. The calorific value of highly compressed briquettes is much greater than of lose material also optimising the combustibility characteristics. Additionally, explosive dust can be handled more safely. Efficient re-utilization of biomass as a cheap alternative fuel source cannot be ignored, particularly in the production of agricultural foods.

Air pollution control for the ethanol/biodesel industry

by Anguil Environmental Systems, Inc.     based in Milwaukee, WISCONSIN (USA)

Renewable energy plants are expanding and developing at a significant rate in North America and throughout the world. In the United States, the Clean Air Act for reformulated gasoline (RFG) mandates a 2wt.% oxygen requirement, driving the demand for more production. Ethanol is the most viable additive because it is a clean-burning fuel produced from renewable, domestic biomass sources. However, the production of these fuels can result in unacceptable levels of volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM) and hazardous air pollutants (HAPs), all regulated by environmental agencies.

Flaring Solutions for the Biogas Industry - Siloxane Destruction

by ABUTEC LLC     based in Kennesaw, GEORGIA (US) (USA)

Biogases are emitted into the atmosphere through a variety of products. Often, these biogases contain siloxanes, non-toxic compounds that are frequently added to consumer products, such as detergents, shampoos, deodorants (to improve texture and feel), cosmetics, paper coatings and many textiles. While some siloxanes quickly volatilize into the atmosphere, others remain present and can be found in the biogas emitted from wastewater treatment facilities and anaerobic digesters.
