WebProcedure for Cleaning Glycol from Engines. A flushing procedure proposed by one major oil company to remove glycol from engine internal surfaces involves the use of Butoxy-Ethanol (trade name Butyl Cellosolve, Union Carbide). The flushing procedure for conditions of less than five percent glycol contamination is summarized below: 1. Most of the steam systems have carbon steel pipelines which will have a lot of rust, welding spatters, and slags inside during the construction. The chemical cleaning will reduce the duration of Steam lines flushingby 1/3rd of the actual duration. This will reduce the Project schedule and improve the quality inside the … See more The following image (Fig. 1) shows a typical flowchart used for the chemical cleaning operation of the steam piping.
