New two stage separators
New two stage separators remove entrainment and particulates from gas streams.
These knockout vessels use vane type and wire mesh type mist eliminators. The vertical vessel design has a small footprint and is especially effective in process and pollution control applications with fouling tendencies, the company notes.
The vessels are equipped with spray cleaning systems to deal with fouling. Cleaning can be intermittent, continuous, or pressure drop activated.
During operation, the gas or vapor passes first through the vane to remove the bigger droplets, fouling substances, and solid particulates. The wire mesh type mist eliminator located in the second phase will remove the finer droplets. The captured fluids drain through the bottom of the vessel. Over time the mist eliminators can be easily accessed and replaced, the firm says.

New wireline logging head
A new wireline logging head provides an improved means of connecting tools, such as casing collar locators and perforating guns, to the remainder of the string.
It features an electrical disconnect that prevents premature release, as well as the associated disruption and lost time.
The logging head's compact slimhole design, which is as small as 11/16 in., means that it is versatile as well as easy to assemble and install, the company says. The system's dual check valves may be removed or replaced with other valves, such as flapper valves, so that it is adaptable.
The logging head features a top connect that attaches to coiled tubing and check valves that allow fluid to be pumped downhole but prevents fluid from returning. In the event of an emergency, its cable weak point allows the cable to be broken and pulled back. The electrical disconnect makes it possible to plan a separation of the head from the string. In addition, its fishing neck allows operators to pull the separated string following a disconnect operation.
Its nonrotating bottom connection allows easy attachment to other tools located below when they are held by grips.
In operation, simply screw the top housing onto the coiled tubing connector, then insert the check valve cartridge. Make up the cable weak point and screw the electric release into place with the rest of the tool string. In cases where separation is required, the electrical disconnect is released by simply applying a reverse voltage for 2-3 min.

H2S sensor continuously monitors for toxic gas
The new Model 4107-05 hydrogen sulfide smart sensor-transmitter is a complete stand-alone fixed-point module providing accurate measurement in the 0-50 ppm range, digital display of gas concentration, nonintrusive calibration, dual alarm relays, fault alarm, MODBUS communications interface, and a linear 4-20 ma signal of gas concentration.
Alarm indication includes an LED indicator plus relay contacts for two gas concentration level alarms plus either a third alarm level or a fault alarm. The two-line 32-character display provides menu prompting information for system configuration plus detailed information about gas concentration including engineering units and device tag name data.
The nonintrusive calibration feature enables the operator to calibrate the sensor in the field without declassifying the area. Using the magnetic tool and the digital display the user can step through the calibration process quickly and easily, the firm says. The 4-20 ma signal can interface with most industry specific devices.
The bidirectional RS232/RS485 MODBUS protocol serial port enables communication along a serial bus data highway.

New Coriolis mass flowmeter
The new PROline Promass 80E Coriolis mass flowmeter offers added electronics and new pushbutton features. This multivariable meter has an accuracy for mass flow of ±0.35% in liquids and ±0.75% in gas.
The Promass 80 transmitter has a two-line, backlit display, allowing two measuring variables to be freely assigned on the display. It features pushbutton operation and guided setup to make configuration quick and easy. Its self-diagnostic function, with clear text messages, helps simplify troubleshooting.
The Promass E sensor is a dual tube type with a fully welded design. Process fittings, welded directly to the flow splitter, eliminate the need for internal gaskets, reducing the risk of leakage points, and helping ensure process safety. Immune to vibration, Promass E is stable and reliable for process measurement.
