DECEMBER 2017 WET NEWS 17 remove H2S and CO2, but usu- ally require a pre-treatment to achieve low concentrations. Failing that, a post-treat- ment is required to remove H2S from the exhaust air. As well as offering desulphurisation tech- nologies, including a chemical process (Sulfurex CR), a bio- logical process (Sulfurex BF), a biochemical process (Sulfurex BR) and activated carbon for small loads, DMT has devel- oped a system to help AD developers select the best suited desulphurisation tech- nology for their plant. The Sulfurex Selection Work Expert Tool (SSweet) cor- relates the plant's gas flow rate and inlet H2S concentration figures to identify the best Plant operators using feedstock rich in sulphur-containing proteins (e.g. slurry) should be especially vigilant THE CONCEPT • The Sulfurex Selection Work Expert Tool correlates gas flow rate and inlet H2S concentration figures to identify the best suited technology • A tailor-made business case is generated by considering site- specific conditions NEED TO KNOW 1 Biogas produced through the decomposition of organic matter contains hydrogen sulphide 2 Removing H2S can increase uptime by 50% to 30,000 hours 3 The most damaging side effect of H2S is its ability to corrode essential plant equipment 4 For high concentrations of H2S, chemical scrubbers are usually recommended, while for biogas upgrading, activated carbon filters are typically used as a pre-treatment suited technology from both a performance and financial standpoint. In addition to this, a tailor-made business case is generated by considering site-specific conditions (such as electricity price, water price, caustic price, discharge cost or labour cost), and uses a mathematical model to esti- mate the total cost of ownership. By combining a pre-selec- tion step with a tailor-made business case, the SSweet allows an AD plant operator to select the most suitable tech- nology for their project from both a technical and financial standpoint, preserving the life of their plant – and their profit margins – for years to come. THE VERDICT "The SSweet allows an AD plant operator to select the most suitable technology for their project from both a technical and financial standpoint, preserving the life of their plant – and their profit margins – for years to come" DMT AD operators use the Sulfurex Selection Work Expert Tool (SSweet) to determine the best desulphurisation technology THE AVK UK SERIES 01/79 SUPAPLUS TM SOCKET CONNECTIONS, WEDGE GATE VALVE PERFECT FOR A QUICK INSTALLATION! AVK recommend that the Series 05 internal support bushes should always be used with polyethlene pipe systems. The new AVK Series 01/79 Resilient Seat Gate valve with integral tensile end load resistant adaptors has design features that deliver ease of fitting, reduced overall cost, reduction in connections and reduced excavation size. All of which make this valve easier, quicker and cheaper to install. BENEFITS: • No fused joints required – full tensile resistant mechanical joints with simple torque wrench required for installation. • Less materials – no PE stub flange, bolt/gasket sets, no EF couplings required. • Installation time significantly reduced - Less time spent in trench for installation, therefore reducing health and safety risks. • Full AVK design and UK manufacture, with holiday free internal coating, WRAS approvals, BS 5163 and WIMES 8.09 compliant. • Cost savings – reduction in time and materials result in a minimum of 20% installed cost saving.
