operation, or routes around line-of-sight obstacles, forming multiple networks when necessary. When the obstruction is removed communication quickly reverts back to one network. Oldham says the BM 25 packs the benefits of a fixed system area monitor into a rugged, user-friendly and transportable instrument. It is designed for mobile or temporary work applications, team protection, area surveillance or locations where fixed detection systems are not suitable. Next up is Detcon, which has
introduced the Sentinel SiteWatch – an advanced networking device that provides safety-critical information on gas and flame detection systems through Ethernet or cellular communications. Te Sentinel SiteWatch connects Detcon wired or wireless gas and flame detection systems to a user’s smartphone, tablet, laptop or PC and provides email messaging with date and time stamps for all alarm and fault conditions that occur. Te Ethernet version includes a webpage that can be accessed from anywhere in the world and allows real-time viewing of detector type, serial number, location/name, gas concentration, gas type, alarm and fault status, along with battery life and communication link quality for wireless systems. Strong SSL/TLS-based encryption is used to provide communication security over the internet. Te Sentinel SiteWatch
connects to Detcon Controllers X40, MCX-32, and Site Sentinel SmartWireless CXT, through RS-485. Last is Simtronics. Tis company has launched the MultiFlame series DF- TV7-T and DM-TV6-T, the first triple-IR flame detectors to be certified up to safety integrity level SIL3. Te devices recently underwent functional safety assessments by LCIE Bureau Verita and were found to be in compliance with IEC 61508:1-7. Te detectors provide fast and accurate detection of hydrocarbon fires while ensuring reliable false alarm immunity. Based on 3IR technology, the detectors provide one of the longest distance-to- detection ranges on the market – for example, 260ft for n-Heptane. In another new development,
GasSecure’s GS01 wireless infrared hydrocarbon gas detector is aimed at demanding industrial applications such as offshore platforms, terminals, tank farms, drill sites and petrochemical plants. Installations are totally free of cabling, meaning project cost reductions of between 60% and 80% when compared with wired devices.
Te detector is designed for use in
SIL2 certified safety systems. According to GasSecure it provides an excellent example for the flexibility of the ISA100 Wireless protocol through creative integration of a PROFIsafe layer over the ISA100 Wireless mesh network communication layers. l
Production capacities (figures end of 2012) for BP in Geel are PTA (purified terephthalic acid): 1,300,000 tonnes per year; PX (paraxylene): 700,000 tonnes per year. Total capacity is 2,000,000 tonnes per year.
“BP is committed to reducing waste, emissions and discharges and ensuring that production facilities such as BP Geel meet the highest standards of health, safety and environmental performance,” said Bob Karschnia, vice president, wireless at Emerson Process Management.
The BM 25 Multi Gas Monitor also features a powerful audible alarm (103 dB @ 1m); ultra- bright flashing signal (viewable at 360°); run time of up to 170 hours; more than four-month datalogging capacity; and is easily transportable, weighing less than 7 kilos.
Novel thermal mass flow meter solution launched A
imed at production and refinery engineers responsible for measuring, monitoring and flaring waste gas, the
new ST100 Series thermal mass flow meter from Fluid Components International (FCI) with FCI’s VeriCal in-situ calibration verification system combines precise air/gas measurement capability with the convenience of in-situ calibration verification. Described by the company as a totally novel solution, it
reduces flow meter operating costs in flare gas applications aboard offshore platforms, at land-based oil/gas facilities and in petrochemical plants. Te system complies with the US Minerals Management
Service (MMS) mandate per final rule, 30 CFR Part 250, Subpart K, Section 250, stipulating that all domestic US offshore rigs processing more than an average of 2,000 barrels of oil per day must install flare/vent gas flow meters.

Tese regulations are intended to protect the environment through the monitoring of greenhouse gases (GHG). Validating flow meter calibration to meet regulatory
requirements is no longer labour intensive, costly or challenging with the VeriCal in-situ calibration system. Te system verifies flow meter calibration in minutes without removing the meter from the pipe or process. In the past, flow meters had to endure the cost and hassle of being pulled from the process, then returned to the manufacturer or a calibration lab for testing and then shipped back for re-installation.
FCI says the ST100 Series flow meter sets a new industry benchmark in process and plant air/gas flow measurement, offering the most feature-rich and function-rich electronics available. gas flow measurement applications for today and tomorrow. l
