Model 880 NSL
AMETEK, the leader in tail gas analysis for over 25 years, is proud to introduce Model 880-NSL (No Sample Line) tail gas analyzer that eliminates plugging in the sample line, long identified as the number one operational problem.
This compact, rugged transmitter-style analyzer mounts directly on your process pipe.

Model 881 NSL H2S in Sulfur Pit Analyzer
AMETEK's No Sample Line technology for the sulfur pit. The 881-NSL has no costly troublesome external sample line. The analyzer mounts directly on your sulfur pit lid, eliminating sample line plugging, the number one problem in Claus Plant analysis. The 881-NSL photometer combines an extraordinary long lamp life (estimated 5 years!) with many innovative features designed to minimize maintenance and increase reliability. The 881-NSL is equipped with anti-clogging blowback features. Any out-of-range condition automatically initiates air blowback to clear the sample system. This feature minimizes the chance of costly downtime by reducing sample line plugging. The analyzer continuously monitors itself for proper operation and has built-in alarm features.

Model 910 Hot/wet Multi-Gas CEM
Stack emissions monitoring of hot/wet gases with integral sample system and oven for analysis of streams with dewpoints up to 350°F (180°C). Gases monitored include SO2, H2S, CS2, COS, NO2, NO, NOx, Cl2, NH3 and many others. The Model 910 additionally, has flow measurement capability allowing the instrument to output mass emissions directly.

Model 930 H2S in Sulfur Pit Analyzer
In many sulfur recovery units, produced sulfur is stored in liquid form in sulfur pits. Operators are increasingly aware that sulfur pits present potential danger to plant personnel and overall plant safety. It is therefore critically important to monitor H2S in the vapor space of sulfur pits to ensure that it remains below the Lower Explosive Limit (LEL, 4.3% by volume). Additionally, the presence of rising concentrations of SO2 in the sulfur pit vapor space provides an early indication of smoldering fires. Therefore, on-line, continuous monitoring of SO2 can enable detection of such fires before they get out of control.

HAG (Heated Acid Gas) Probe for use with 931 Analyzer
The sulfur recovery process requires a consistent quality of feed gas to operate most efficiently. Uncertainty in feed stock quality increases with changing feed stocks, depleting sour gas wells and some processing unit upsets. To help ensure maximum recovery efficiency, today’s SRUs demand a faster means of adjusting for input changes than is possible with only feed-back control. Continuous, reliable, on-line analysis of critical feed gas components in sulfur recovery units provides process engineers and operators with vital information for feed-forward control of the modified Claus process. Feedforward analysis can be performed once the sampling challenges unique to the acid feed gas are overcome.
