Welcome to the website of Dahlman Renewable Technology

Since 1885, Dahlman has been a specialist in filtration & separation solutions, providing equipment to clients worldwide. Since 2001 we are cooperating with ECN to develop the OLGA tar removal system. Today OLGA is proven technology, commercially available and presented together with other gas cleaning technologies.

OLGA performance

OLGA performance

The OLGA process proved itself in many lab & pilot scale tests. The performance of OLGA is presented by the results of the 500kW(t) durations tests. Objectives of these tests were to demonstrate that the OLGA process is stable and reliable, that the gas quality after OLGA is on specification for a gas engine or gas turbine. more..

OLGA process philosophy

OLGA process philosophy

The philosophy of OLGA is based on dew point control. OLGA operates above the water dew point, but reduces the tar dew point to a level under the lowest process temperature. Tar & water are not mixed! The tar removal principle of OLGA is based on a multiple stage scrubber in which, the gas is cleaned by special scrubbing oil. In the first section of OLGA... more..
