New dehydration system helps cut emissions
Patented, new Quantum Leap natural gas dehydration technology recovers all BTEX and other hydrocarbon emissions and converts them to process fuel.
The new hydrocarbon-emissions free dehydration system reduces conventional dehydrator operating fuel expenses by as much as 50%, the company says. The skid- mounted dehydration system can be used for new projects or added to existing onshore and offshore dehydrator systems.
Still column and instrument gas vent emissions released to the atmosphere from traditional dehydrator designs are recovered, and noncondensable emissions are used as reboiler fuel.
Condensable still column overhead hydrocarbons are converted into a stable salable liquid product. High gas dew point depressions are obtained without using gas stripping. The system will respond to fluctuations in gas volume just like any conventional gas dehydration system, and the size of QL dehydration systems is not limited.
This patented technology can range from small wellhead dehydrators to large process plant applications.
Compact skid-mounted field units are comparable in weight with traditional dehydration systems. Self-contained QL units have operated unattended in the field for more than 2 years, the firm points out. Electronic data collection and transmitter capabilities are available for remote installations.

New structural, stratigraphic interpretation program
LithoTect, a structural and stratigraphic interpretation program, is designed to create and validate geological interpretations through restoration and balancing.
The LithoTect model construction tools include a suite of dip-constrained and general map, profile, well, and seismic interpretation methods. Its depth conversion, well monitoring, and data projection capabilities are state-of-the-art, the company says. The structural restoration-forward modeling techniques include decompaction-isostacy and operate on both interpretations and seismic data. Emphasis has been placed on making LithoTect easy to learn and use by all geoscientists. Because it is written in pure Java, LithoTect runs on laptops and work stations of all types.
Another feature of LithoTect is its concept of a geometry field associated with rock structures, enabling the geoscientist to examine the bedding and distributions of dip, curvature, and strain that are implied by their interpretations. The geometry fields automatically incorporate mixtures of influencing elements and combinations of geometric styles, including similar and concentric or angular-bend parallel geometries. They also define the slip systems used for restoration-forward modeling-with the ability to blend nonconstant thickness flexural slip and vertical-oblique slip kinematics.

New air pilot switches
A full new series of MAXIMATOR air pilot switches controls the pneumatic signal to an air pilot line and can be used as an on-off device for air operated actuators, pilot operated valves, air driven pumps, amplifiers, and gas boosters.
The switch allows the pump, amplifier, or booster to operate at maximum air drive pressure, reaching the desired outlet pressure as quickly as possible with little overshoot.
Switches can be used for normally open or normally closed operation and replace electrical switches in hazardous liquid or gas services. These switches sense gas or liquid pressures and offer precise and repeatable control of outlet pressures. They are simple to install and externally adjustable under pressure.
Units are available in pressures of 145-14,500 psi. They feature an aluminum alloy body, 440-B piston, T46 Turcon seal, and Buna-N O-ring. Connections include a 1/4 in. FNPT sensing port and 1/8 in. FNPT air ports.

New ball valves, actuators handle shutoff to 20,000 psi
A full line of new trunion style severe duty ball valves and ball valve actuators is specifically designed for effective shutoff of liquid and gas flow up to 20,000 psi. Two, three-way, and three-way diverter ball valve configurations are available in orifices of 0.187 or 0.375 in.
These new valves incorporate 316 stainless steel construction, Viton O-rings, and Arlon ball seats. For panel mounting, the valves also feature a 11/16 in. diameter hole. The two-way valve offers complete shutoff with a quarter turn, and the di verter style three-way valve requires only a quarter turn to change port outlets. The standard three-way valve requires a half turn to change port outlets and allows for complete shutoff.
The firm offers air-operated actuators to accommodate remote operation applications as well as a selection of tube and pipe fittings.
