the improvements to existing technology that now are standards in CO2 industry.These developments, together with TPI’s dedication to continuous improvement, ensure each application is given the latest technology.Compression, purification, deoxidation, production and recovery of gas are the main fields where TPI developed its know-how and technology.

Each improvement is based on data that TPI engineers collected during installation and commissioning of more than 500 plants all over the world.A just-in-time service for Spare Parts from the After Sale Service ensures the proper operation of TPI equipment wherever installed. Pre-assembled units can be tested at TPI’s workshop in simulated on-site condition.

BIOMETHANEGreen and Valuable ResourceIn-house production of Biomethane is an eco-friendly and cost-effective resource that offers interesting opportunities in order to improve agricultural incomes, reducing, in the meantime, their environmental impact. Biogas is a valuable resource which allows you to turn waste into a versatile source of energy, reducing our global dependence on fossil fuels.

The excess of agricultural products, as well as manure, sewage sludges, household wastes, are ideal raw materials for the biogas production.That’s why Biomethane – obtained through Biogas refining - has enormous potential, being the only renewable energy source that can be used for many commercial uses. The end product of a Biogas Upgrading plants

contains more than 99% methane and is available for vehicle fuel or to be fed into the natural gas grid as well as used for power generation.Biomethane production has become even more convenient with the implementation, in each European Country, of the UE Directive 2001/77 regarding the promotion of electricity produced from renewable energy sources.

TPI is able to propose different technologies to produce Biomethane, refining Biogas. CO2 absorption in a selective solvent at low pressure is a Biogas Upgrading technology developed by TPI and based on the know-how built-up in manufacturing, for more than 25 years, plants for production of Food Grade CO2 starting from different gas mixture. The solvent used for Biogas

CO2 is a valuable by-product of Biogas Upgrading process (not being fuel, it should be separated from Biomethane because it lowers the calorific value).TPI’s Biogas Upgrading plants can be equipped with the CO2 recovery section (with efficiency of 99%).This unit consists of a compression stage, a drying and purification step, a refrigeration and liquefaction section and a cryogenic tank for liquid carbon dioxide storage, prior to its use in many industrial field.

application is specifically developed and enriched with suitable additives.Biomethane refining through CO2 removal is a simple process which doesn’t require any desulfurization or dehydration pre-treatment. This TPI technology allows to obtain a very high concentration of methane (above 99%), with a reduced energy consumption and a negligible solvent degradation.

Features• Capacity: from 1000 Sm3/h - to 5000 Sm3/h • Very low power consumption• Low steam consumption• Low washing water consumption

BIOGAS UPGRADING HPSM-Sep Membrane

HPSM Flow Diagram

Use of polymeric membranes with a very high selectivity for Biogas refining is an innovative and reliable solution already tested on industrial scale with significant Biogas stream and high yields.TPI has developed and industrialized HPSM technology for its raw Biogas refining plants in order to obtain levels of methane purity up to 97% and a

recovery efficiency greater than 99%. Fermentation of organic solids produces raw biogas that contains 55-70% methane, 30-45% carbon dioxide and traces of sulfur, nitrogen and oxygen.Refined by a TPI plant it becomes Biomethane suitable for many industrial usages or for injection into the natural gas national grid.

Features• Capacity: from 50 Sm3/h - to 1000 Sm3/h• Delivery pressure: from 10 up to 30 bar• Low power consumption• Execution: Ex Zone 1-2, T2, T3, ATEX

BIOGAS & BIOMETHANE Compressors

BIOMETHANE Dryers

TPI has significant experience in manufacturing compression skids for Biogas and Biomethane, starting from flow rates of 50 Sm3/h up to 1000 Sm3/h.The Biogas compression unit treats the raw gas (before the CO2 removal); it consists of a lubricated compressor, dry running, in special execution for this type of application.

TPI produces an innovative line of dryers for Biomethane which incorporates thewide experience built-up in constructionof many drying systems for Natural Gas installed all around the world, downstream of compressors of different manufacturers. Based on a mixture of alumina and molecular sieves, this kind of dryer allows to dry Biomethane reaching the lowest levels of residual moisture. Dryers for Biomethane produced by TPI are entirely constructed of stainless steel materials.

The Biomethane compression unit works, instead, with clean gas (after the removal of H2S and CO2) and is based on a compressor, single stage or two-stage, with piston sealing rings designed for continuous service. The compression unit includes, if required, the refrigerant drying unit for gas refrigeration.

Features• Capacity: from 50 Sm3/h - to 1000 Sm3/h • Skid mounted, fast installation• Pre-wired and tested at workshop• Full automatic operation• High reliability, continuous operation
