PITTSBURGH, PA, – AMETEK Process Instruments (www.ametekpi.com) has introduced its third-generation H2S/SO2 tail gas analyzer with significant reliability advances for control of the Claus sulfur recovery process. New features of the Model 888 Sulfur Recovery Tail Gas Analyzer address the three most common external failure modes encountered by Sulfur Recovery Units (SRU).
Those failure solutions are:
• Automatic flow control for proactive response to adverse process conditions, such as liquid entrainment during SRU turndown.
• Flange temperature alarm to give early warning of poor steam quality or defunct steam trap to prevent sample flow failure.
• Extended ambient temperature range to 60oC (140o F) without external cooling to increase the life of electronics and allow installation in the hottest climates.
The safety advantages of the new Model 888 analyzer include double-block process isolation and a Web-enabled interface for remote data acquisition by Ethernet and Modbus. The Model 888 features the AMEVision color graphical user interface and smart diagnostics. The unit’s extensive self-diagnostics monitor six temperatures and four separate pressures, with automatic adjustments in process flow. The analyzer also is equipped with steam (hot condensate) blowback to remove ammonia salts and an anti-clogging feature that is automatically initiated if plugging is detected.
The 888 uses the proven sample handling technique of an internal demister with two demister pads and face-to-face fittings allowing improved access and maintenance efficiency. All internal analyzer connections and internal components are accessible from the front of the unit. The compact, rugged analyzer mounts directly on the process pipe eliminating the complexity of fiber-optic coupled photometers or sample lines
Since the Model 888 occupies the same footprint and uses the same process connection as its predecessor, the Model 880, the new unit can be substituted in less than a day. Its stainless steel housing is rated IP65/NEMA 4X for harsh outdoor operating conditions; a shelter cabinet or house is not required
