In-situ, maintenance-free NH3, HCL, HF, CO, CO2, O2, or H2O measurement in petrochemical and refining operations are achieved by tunable diode lasers. Models are also applicable for 02 flare gas or inert blanketing safety monitoring.
LDS6 laser measures NH3, 0 to 10-ppm on the outlet of the Selective Catalytic Reduction of the CO boiler at the back-end of Fluidized-Bed Catalytic Cracking Units. It features lifetime, automatic, online calibration at 24-times/sec, zero drift, no moving parts, with minimal interference and fast response rates.
LDS6 measures up to three points for the same component. It also automatically online-calibrates itself with an internal reference cell 24-times/sec.
Sitrans SL laser measures 02 in process furnaces to replace high-maintenance zirconium oxide units. It measures 02 in-situ for one point with no interferences and without a calibration check for at least 12 months. It has a minimum detectable limit of 200-ppm O2, with a 2-sec response time for Class 1, Div. 1, Groups A, B, C, and D.
