Beneficiary: MND Czech Republic, the main producer in the Czech oil and gas market

Partnership with GHH RAND

Since 1999 GHH RAND and Comoti- cooperate in the gas compression business- GHH RAND’s oil injected CU- and CF-series have been the heart of Comoti’s gas applications- Effective January 2009 Comoti exclusively manufactures and supplies the CU-series basis a license agreement- Licence agreement renewed in 2014 for more 4 years- Since 1999 Comoti is taking customer’s requests on all kinds of compressed gas applications- COMOTI project is to extend the existing gas turbines portofolio with 6 MW output class in order to cover national market needs in partnership with GHH Rand and MAN TURBO

High efficient generation of electric and thermal power with gas turbines (CHP)

by the implementation of the

first co–generation power plants

in the country.

They are opening the

perspective of supplying the

consumers with thermal power

at much lower cost than at

present.

New Projects

• EXPANDER GROUP- ELECTRIC GENERATOR

• Producing the green energy by recovering the energy detention in the lamination process of the natural gas (mechanical energy can be recovered and converted into electrical energy) using a turbo-generator

• The solution can be implemented in any regulating and measurement station of gas natural transport

• The prototype fulfills all requirements of functional and constructive design and it is already installed at Trans Gaz Onesti

• Nominal parameters in this case: -suction pressure 20 bar -discharge pressure 3.5 bar -flow 6,000 Nm3/hour (1500 rpm ) -electrical power 180 kW
