Procedural Optimization of Biogas and Exhaust Air Treatment of a Biogas Plant in Schöpstal

Summary/Description

The company SPIE Energy Solutions GmbH operates a bio gas plant in Schöpstal nearGörlitz. The plant constantly feeds 750 Nm3/hbio methane into the natural gas grid (60 bar).

The existing Voxibox (product name of a regenerative thermal oxidation) was substituted by a different RTO for optimal functioning of exhaust air treatment so amethane slip of approx. 2 % at an exhaust air stream of approx. 3,000 Nm3/h is ensured.

For the operator of the plant the employer SPIE has designed a technological process concept to reduce methane slippage andsimultaneously provide cost effective cooling / heating energy. The concept is innovative. The exhaust air is cleaned by using regenerative thermal oxidation (RTO).

The cleaned hot exhaust air from the RTO (approx. 300 °C) is used for heat utilization twice and shall be subsequently cooled to approx. 100 °C. The gained heat and cold is used within theplant.
