New work stations for harsh environments
New operator interface work stations are designed for harsh environments.
The new SafeTTouch D2 is a nonpurged touch screen work station for Class I, Divi sion 2 applications, and the SafeTTouch EX is a flameproof, explosion proof touch screen work station.
SafeTTouch products feature Enhanced Infrared touch displays, a technology that was designed for safety in harsh and hazardous areas.
Enhanced Infrared touch screens use a matrix of invisible light beams to detect operator input and maintain their calibration without drifting. The company says its units are operationally immune to cuts or wear of the touch surface, and the touch screen is covered by a 5-year warranty.

Software yields boiling point data quickly for refiners
A new leaflet, free for the asking, discusses SIMDIS software, version 06.02, which promises refiners fast and accurate boiling point data to help monitor pro cesses, control product quality, and expand product yield.
The software operates on different gas chromatograph systems, which access the software to calculate results automatically. The software also enables operators to work stand-alone loading data analyses and performing setup and calculations.
Refiners can use the software over a network as a client/server system for data reprocessing purposes.
The software includes preprogrammed settings of ASTM, DIN, IP, or ISO methods that contribute to data precision and help provide an assured reproducibility.
The preprogrammed settings include:
- GC method settings.
- Standard calculation algorithm.
- Precision upper and lower limits.
The software offers reports customizable to lab requirements including:
- A chromatogram with merged baseline, carbon numbers, initial and final boiling points, start and end elution points, and net corrected area.
- Report of the peak skew and column resolution.
- Table and graph with boiling point vs. retention time.
- Table with cut points and fractions.
- Table with several correlations, including ASTM D 86 and D 1160 calculations.
- A validation report that lists found values vs. preprogrammed values.

New process gas monitor
PIRVOL, a point-infrared volumetric combustible gas monitor, is designed to measure hydrocarbons in the range of 0-100% by volume.
Suited to wellhead mud logging and hydrocarbon processing, the instrument is CSA-approved for Class 1, Division 1 groups B, C, and D, and Division 2 groups A, B, C, and D (T3C) hazardous areas, and conforms to EN50081-1 and EN50082-1 standards.
Supplied with a 5-year warranty and featuring sapphire optics for hardness, the device has no undisclosed failure modes. It is self-monitoring with built-in diagnostic information, needs no routine calibration, and offers reduced maintenance costs.
This process gas monitor operates in oxygen depleted environments and also performs in prolonged exposure to high concentrations of background gases, being unaffected by silicones or hydrides.
A hydrophobic screen promises superior optics protection, and the instrument's small form factor enables easy system integration, the cocmpany says.

New flow remediation system
A new flow remediation system is capable of removing virtually all types of restrictions and blockages from subsea flowlines.
By utilizing composite coiled tubing, the GoFlo system is deployed into flowlines, and a combination of chemical, mechanical, and thermal treatments are applied to clear blockages and restrictions.
Depending on flowline configuration, the service can be deployed from one of this firm's specialty vessels or directly from a production facility.
The system can be used to remediate blockages that include viscous organics, hydrates, scales, or mechanical debris.
The system has a target reach of 20 miles and can work in conditions of up to 5,000 psi and in temperatures up to 180° F.

New polymer added to range of paraffin inhibitors
A new grade has been added to this company's paraffin inhibitors and is marketed under the trade name Prochinor AP 757.
The new polymer is particularly effective as a paraffin inhibitor in oil production and condensate installations.
It is injected into the equipment in a continuous process to prevent paraffin deposits, and its properties help improve output as well as the transportation of oil and condensates.
The company says Prochinor helps prevent paraffin deposit formation by keeping the paraffin dispersed in the fluid. Also, it lowers the pour point of oil and condensates and helps improve the rheological properties of the fluid at low temperature.
