Unloading multiple tank cars can present challenges for the plant designer and operator. Selecting the correct reciprocating gas compressor and designing a proper piping system can make the daily operations of a plant very efficient. However, if done incorrectly, it can create operational issues that are difficult and expensive to resolve.
Large scale unloading operations can see significant benefits from certain design parameters incorporated at the plant design stage. Many details are specific to the particular location, product being unloaded, owner’s preferences, etc. However, some general guidelines can be applied to nearly all multiple tank car unloading applications
Two such guidelines are the proper selection of the gas compressors, and the method of vapor pipe routing. At Corken, we have been building tank car unloading compressors since the 1940s. Our experienced application engineers can help you select the correct compressor for the job. The following pages show some general guidelines for selecting the correct compressor and properly routing the vapor piping.
