Oxygen Control in Gas Phase for Safely Recovering Flammable Solvents
Our customer is an innovative waste management company centrally located in Arkansas, USA. It manufactures fuel derived from waste oils and solvents that is used as a secondary fuel source to replace coal and natural gas in cement kilns.
The facility has two different applications of gas-phase oxygen measurement; in the headspace of metal barrel shredders and in a thermal recovery unit.
Most of the waste solvents arrives at the facility in metal 55 gallon drums. The bulk of the liquid is drained from the containers and collected. The drums are decontaminated from residual organics using further heat treatment which first requires the metal containers to be shredded into manageable pieces (see figure).
