Recently, S&S Technical was approached about developing a portable hydraulic drive compressor package for a client in Ohio. The compressor would be used to evacuate LPG products – Propane, n-Butane and Isobutane from damaged railcars, allow them to complete repairs and re-certify them for service.
Process gas compressor applications have changed very little over the last several decades. What has changed are the requirements for an oil-free compressor that can minimize Volatile Organic Compound (VOC) fugitive emissions and provide long term reliability.
When designing a pipeline metering skid there are considerations as to which type of meter to use, Coriolis or Turbine. Temperature, system foot print, and flowrate are a few to be considered as there are positives and negatives with each. To make the best decision let’s review based on the fluid or gas being metered through the pipeline.
Unloading liquefied gases from pressurized railcars have a very unique set of challenges. The product and vapor connection are located on the top of the car and the product (liquid) connections include a suction tube that extends into the car but does not reach the bottom.
S&S Technical is a leader in the design, fabrication, and automation of crude oil, NGL, and petrochemicals. Our clients include industry leaders in the oil and gas industry. We’re dedicated to employing and investing in the latest technologies to aid in the engineering of their packaged fluid and gas transfer pump systems.
Vapor Recovery Packages are now a standard piece of equipment at most tank farms, well sites and process facilities. EPA and local air quality standards require companies to capture fugitive emissions and VOCs, limiting the venting and flaring that has historically been acceptable.
