H2S Detection |
| TRACE 400 High Range |
TRACE 400 When dealing with H2S amounts in excess of 500ppm, it is necessary to add a dilution system to decrease the concentration to measurable levels by the Trace detector. While this decrease the Resolution slightly, it is necessary for detection at these levels. AIR DEMAND (CLAUS PLANT) Determines the H2S content for total air required to combust H2S in the feed gas to the Claus Plant. Two thirds of the H2S is subtracted from the total air demand to yield a control signal to the acid gas/air controller to maintain the correct stoichiometric ratio of H2S/SO2 for maximum sulfur recovery. It provides a fast acting feed-forward control of the burner air. DIAGNOSTIC ALARM The alarm provides contact output to alert operations in the event of one of the following fault conditions:
SMARTALK SMARTalk provides complete remote operation via personal computer or host with true bidirectional communication. The operator does not have to travel to the measurement site to alter operation, initiate calibration, or view data. Controls, reports, and data are available at lab or office via a personal computer link. Remote access reduces the chance of "no fault found" service calls where on site trips find no fault with the equipment. LCD GRAPH DISPLAY The display is a paperless chart recording of the concentration with selectable time scale to make comparisons and graphically display operating trends over time. CABINET HEATER A heater with thermostat control is integrated into the cabinet which provides freeze protection throughout the cold winter months. This will prevent the humidifier solution from freezing in sub zero temperatures causing the unit to malfunction. This will drop the lowest allowable operating temperature 15°C to -10°C. VAPORIZING REGULATOR The vaporizing regulators vaporize a liquid into a gas then perform a single stage pressure reduction on the gas. Pressure drops through pressure regulators may cause cooling which allows liquid to form. The vaporizing regulator puts heat back into the flow media to insure that is stays a gas. CHART RECORDERS A hard copy record of 4-20mA output is available in:
AUTO CALIBRATION The auto calibration provides software algorithm, contact outputs, solenoid valves, tubing, and customer connections for automatically calibrating analyzer at pre-selected time intervals. REMOTE DISPLAY AND ALARM This option uses the 4-20 output from the analyzer to generate a digital display of concentration and adjustable alarm contact outputs MULTI-STREAM This option allows the analyzer to select and analyze more than one sample source. This is ideal for any situation where more than one sample source is present. CAL TAP The calibration tap point includes the connection fittings and tubing together with a three-way ball valve to easily connect calibration gas to the analyzer. |
CABINET STAND The cabinet stand is a pipe stand with mounting holes for outdoor and indoor use. TRACERASE TRACErase uses technology based on a catalytic combustion process to oxidize vented samples thus preventing fugitive emissions from entering the atmosphere without causing back pressure on the analyser. Packaged to provide explosion proof protection, this unit may be used in hazardous locations. SOLAR POWER This option includes batteries, a solar panel, and charge control to maintain analyzer operation in remote locations CORROSION PROOFING Using stainless steel instead of galvanized steel in the construction of the wiring conduits will reduce the risk of corrosion of the instrument; all of the conduits in the analyzer are replaced with their stainless steel counterparts.
