GAS-ENRICHMENT INSTALLATION TO UPGRADE COAL-MINE GAS FOR THE USE IN THE OBERHAUSEN GAS DISTRIBUTION NETWORK

Cel

To build a compressor and a gas-enrichment installation (pressure-change-adsorption system) to bring the coal-mine exhaust gas of the Sterkrade mines to a fuel value equivalent to that of natural gas and feed this gas into the gas network of Oberhausen. The nominal output of the installation is 3500 Nm3/h of upgraded gas.
The reuse of the mine exhaust gas currently flared is estimated to save 9,152 TOE/year. In the FRG there are 22 coal-mines where this technology could be applied with similar benefits leading to a total saving of 1% of the gas imported in the FTG (62.9 billion m3) equivalent to 192,890 TOE/year.

The Sterkrade pit has 3 gas suction devices whose function is to eliminate the methane gas from the coal-mine. Some 20% of the mine gas can be reused in the central boiler of the mine, but 80% finds no application and is flared. This project intends to upgrade this gas to a quality suitable for distribution in the natural gas network of the town.
The mine gas contains a methane portion varying from 26 to 44% and must be enriched to 87%. This is achievable by using a "pressure-change-adsorption" installation (DWA-Anlage) which consists of separation-columns and a buffer storage tank containing molecular sieves. The mine gas passes through the separation-columns where the methane is adsorbed leaving a methane-free exhaust which is then partly recirculated into another column where it re-collects the previously adsorbed methane until the necessary concentration. The upgraded gas is then compressed and fed +/- 80% into the network, and the remaining 20% is used for covering the requirements of the mine.
The total cost of the project amounts to DM 10,619,590.-.
The "DWA" equipment will be installed by Berghau AG Niederrhein (BAN), a 100% subsidiary of the contractor. A contract covers the subcontracting by Ruhrkole to BAN. Patent coverage exists.
