Biogas - its your revenue stream - make the most of it!
17 September 2010, News release from Gas Data Ltd
With the current emphasis on renewable energy, there is an ongoing concern that gas being produced by Anaerobic Digester (AD) units for use in Combined Heat and Power (CHP) applications is not being adequately monitored - but Gas Data's GFM series of portable hand-held analysers and fixed site Click! System are at the ready!
The gas (biogas) is a mix of CH4 (methane), CO2, (carbon dioxide), H2S (hydrogen sulphide) and O2 (oxygen). If the level of CH4 - the money making gas - is not being monitored the user has no indication of how to best utilise materials to gain optimum revenue and if the corrosive and potentially damaging H2S level is going undetected it may be eating away at expensive internal engine components, causing numerous problems not to mention cost of repair and downtime caused.
The instruments are designed to monitor all of the biogas elements and provide users with a detailed breakdown of what gases are being generated by the AD unit. Armed with this valuable data, comparisons can be made between outputs created by differing feedstock and operating conditions so leading to the rapid identification of optimum conditions that maximise revenue from the plant. In general CH4 should be maximised whilst H2S levels should be minimised to avoid damage to the engines, plant and excessive sulphur levels (SOX) in the engine's exhaust gas.
Put simply, maximum production plus minimum maintenance equals best revenue!
The GFM series of portable analysers have been designed for the biogas sector and as standard come with CH4, CO2, O2 and H2S channels. They are easy to use, light in weight and give precise data which can then be downloaded for ease of comparison and interpretation.
Gas Data's Click! Fixed site system is a modular design having individual 'modules' for valves, pumps and gas analysers which can be changed by any competent technician if and when required. Simply Click! the chosen module from its DIN rail, Click! the new, previously exchanged, unit in its place and then post the old module back to Gas Data for factory re-manufacture. This process reduces costly service visits and downtime to minutes.
All Click! Systems are optimised to take accurate readings within an acceptable response time. Gas Data's engineers will advise which sample system will give best data and highest reliability. For example, for gas streams directly from an AD unit (typically in the gas storage container) where changes in concentration are inherently slow a cyclic sampling system (one to four times per hour) is super reliable and extremely cost effective. Conversely a gas stream feeding the input of a CHP unit can be subject to rapid changes if errors occur on the plant. Under these conditions the gas analysis must be done as quickly as possible (typically less than 30 seconds) so a continuous sample system should be used. These systems require a slightly more complicated pre-treatment of the sample before passing to the analysers but there are Click modules available to meet this demand. Click! Systems are highly versatile - cyclic sampling, continuous or anything in between!
The data software available for these units helps to translate the information read by the system and store it for future purposes. As well as gas analysing the fixed site Click! System can also be programmed to give warnings should a certain gas level exceed its set parameter, such as H2S reaching high levels.
Since the Click! Systems successful launch in late 2009, Click! Systems have been installed and are up and running on many sites in the UK and World Wide. A healthy order book means many more are on the way for Gas Data as they Click! ahead with fixed site on-line biogas monitoring.
Gas Data are so confident of their product and the need to monitor biogas, they are offering the chance for those who visit their stand (C17, EBEC) the chance to win the hire of one of these instruments (fixed or portable) free of charge. Visit them at stand C17, EBEC 2010 to be in with a chance to see for yourself how important monitoring biogas is - after all 'its your revenue stream - make the most of it!'
