An energy company’s process furnaces were experiencing excessive coking, leading to wasted energy and frequent downtimes for tube cleaning. After installing WIKA’s Tefracto-Pad ® thermocouples, the energy company enjoyed longer run lengths between decoking …
WIKA conducted a series of tests – both in the field and using computational fluid dynamics – to evaluate the accuracy of tubeskin thermocouples (TSTCs) when installed on a butter-pad vs. on a bare tube. We also varied the weld material’s orientation …
A butter-pad allows refineries to weld new thermocouples onto it rather than directly on the bare furnace tube, as repeated welding damages the tube’s integrity. However, using this weld overlay affects the accuracy of temperature readings. WIKA conducted a series of …
A measure of performance and dependability, Safety Integrity Level (SIL) ratings take into account on-demand failures and risk-reduction factors, and is valid for five years. Reapproved on January 28, 2022, WIKA’s SIL 3-certified multipoint thermocouple assembly …
Low-level flue gas recovery allows refineries to improve their heaters’ efficiency. However, this process could lead to the condensation of flue gases, and these acidic droplets can corrode equipment. For optimal safety and efficiency, refineries must monitor …
