Welcome to the website of Dahlman Renewable Technology

Since 1886, 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..
