Safe flow confirmation in Sulfur Recovery Unit rundown lines


For many years, refineries and gas plants have employed methods for viewing liquid sulfur flow through their rundown lines, including look boxes and various sight glass devices.  Standard look box designs require the operator to open a hatch door to view the liquid sulfur running through the piping.  This activity potentially exposes the operator to H2S vapor and/or liquid sulfur spray.  To limit operator exposure risks, many attempts at closed sulfur viewing devices using sight glass ports have been introduced.  The common issue with those devices, however, is fogging of the sight glass which hinders visibility of the liquid sulfur flow. 

Addressing issues with current technology, CSI has partnered with oil and gas industry leaders to develop a safe, reliable sulfur flow indication device. CSI’s patent-pending SxView™ design ensures consistent, safe visual confirmation of liquid sulfur flow.  Moreover, the SxView™ is backed by CSI’s engineering expertise, expansive production capacity, and exemplary customer service. As such, CSI’s SxView™ delivers the technical and commercial value you’ve come to expect from CSI for over 50 years.

The benefits of the SxView™ include:

  • Safe, visual confirmation of liquid sulfur flow
  • No sight glass fogging or solid sulfur freezing
  • Easy to install
  • Rod-out capability
  • Easy to maintain
