Antistatic coating for hazardous area enclosures

Intertec has launched an advance in antistatic surface coating treatment for its GRP (glassfiber reinforced polyester) outdoor enclosures. Developed specially for Intertec by the chemical specialist BÜFA, the new nanotechnology-based coating also boosts protection against damage from ultraviolet radiation - helping to achieve extended maintenance-free lifecycles of field-based control and instrumentation equipment in processing industries such as oil, gas, chemicals and petrochemicals. Intertec's weathering tests in an environmental test chamber have demonstrated that the new coating can withstand extended exposure to very high UV levels - providing a new level of protection particularly for GRP field enclosures destined for environments such as deserts, the tropics or the Arctic.

Dubbed GO-Antistatic, the new treatment is based on an advanced carbon nanotube material that is applied as part of a surface gelcoat. Polyester gelcoats are widely used to add glossy and highly durable surface finishes to the exterior of GRP enclosures. The advanced nanomaterial provides a degree of conductivity for the outdoor enclosure that dissipates any static electric charges safely to ground - to protect against sparking. Such treatments ensure safety in hazardous areas of processing plants, where a spark caused by the build up of an electrostatic charge can cause an explosion of gas, vapour or dust in the local atmosphere.

Gelcoats are a premium form of protection, and form a chemical bond on the surface of the GRP. Most of the antistatic treatments applied to GRP enclosures today rely on the addition of conductive materials into the surface gelcoat (or conductive paint) by employing carbon/graphite, tin or other metals. However, if the gelcoat contains antistatic material, this can have a detrimental effect on its performance, notably in terms of reducing its smoothness and ultraviolet protection, and limiting the colouring possibilities. Extended exposure to high UV levels can then damage GRP enclosures, leading to minor surface roughening - which is sometimes referred to as chalking or frosting.

Intertec and BÜFA worked together to develop the new antistatic coating. BÜFA chose single-wall carbon nanotubes (SWCNTs) to provide the required conductivity and has developed proprietary techniques to disperse the SWCNTs in the coating material. This approach provides numerous benefits largely because SWCNTs are incredibly small - around 1-2 nanometers in diameter - which increases smoothness at the surface level of the coating. The gloss retention (smoothness) after accelerated weathering tests is about 50% better than the previous formulation, and is on the same level as non-antistatic gelcoats. This significantly improves UV resistance, and additionally virtually eliminates any effect on the use of any decorative colourings. 

This latter advantage means that Intertec can also now provide hazardous area enclosures in a much broader range of colours than was previously possible. Options will include almost pure white for example - which will further aid solar protection, something that is very difficult or impossible to achieve with many current antistatic treatments. Intertec can also now provide enclosures in colours that match a client's corporate branding for instance, or help with other desirable attributes such as camouflage or blending with architecture.

    Intertec Instrumentation produces protective enclosures for field-based process instrumentation and control equipment, using glass fiber reinforced polyester (GRP). This material offers remarkable advantages for oil and gas applications (including natural corrosion resistance, low weight, extended durability for long life applications, much higher thermal resistance than metal – making it easier to insulate against heat and cold – and benign environments for wireless communications). Our broad range of enclosures, cabinets and shelters, plus a comprehensive selection of accessories including heating and cooling components, protect against freezing, condensation, solar radiation/UV, explosion, fire, corrosion, impact, etc. We have designed and shipped over a million instrument protection enclosures since 1965, to protect equipment operating in the most demanding operating conditions on Earth - from Arctic regions to deserts to harsh coastal and offshore environments. Application-specific protection may be configured using free software tools. Or, Intertec will configure a turnkey solution for you, using know-how that has evolved over more than 40 years. Intertec manufactures in Sarnia, Ontario, and a site in Houston, Texas with local assembly and system building capabilities.

RMP Energy announces Elmworth battery start-up

RMP Energy Inc. has announced the recent successful commissioning and start-up of its 100% owned and operated Elmworth 2-23 oil battery and gas handling facility in the Elmworth (Gold Creek) field of West Central Alberta. The 2-23 Facility is presently handling the initial crude oil and natural gas production from two (2.0 net) of RMP's Middle Montney drilled wells (3-22-68-3W6M and 4-18-68-2W6M). Early-stage well production results are encouraging and the Company anticipates providing detailed production data once the wells produce for at least thirty calendar days. The start-up of the 2-23 Facility marks an important corporate milestone for RMP as it enables the Company to begin realizing commercial benefit and return of its capital investment from its new core area, which encompasses 82.5 net sections (52,800 net acres) of acreage prospective in the Middle Montney reservoir. The 2-23 Facility, which can be expanded as required, has initial design capacity to handle 1,500 bbls/d of crude oil, 8.2 MMcf/d of natural gas and 7,500 bbls/d of emulsion.

TESTS SHOW VOLVO AT 20 PERCENT LOWER COST PER TON

The Volvo EC350E and EC380E were put up against two industry leaders to see how each would perform in terms of productivity and fuel efficiency. The four comparable machines were equipped with fuel meters and put through the same test, loading trucks at maximum power. The results were used to calculate estimated time and cost to move 551,156 U.S. tons (500,000 metric tons) of material. Calculations are based on 50-minute work hours, 8 hours per day.

The Result: Volvo delivered a 20% lower cost per ton and moved 15% more material per hour. Get tips about how to get the most from your excavator at volvoce.com/exfactor.
