Project name: Chemical Plant Gas Detection Upgrade.
Industry: Pulp & Paper.
Location: N.I. Central, New Zealand.
The customer’s challenge
The site of New Zealand’s largest chlorine production and storage had insufficient gas detection and being an old plant, there was potential for gas leaks of one of the most toxic industrial gases. Replacement of existing detectors had traditionally been on an ad-hoc basis and the hazardous area standard acceptable in the New Zealand market had changed from ATEX to IEC Ex. There was also increased interest from the customer for instruments that met an international Safety Integrity Level (SIL 2 or SIL3).
There are a number of toxic gases on this site, including chlorine, chlorine dioxide, ammonia, hydrogen sulphide as well as flammable gases such as methane which is the main constituent of natural gas used on boilers, furnace and kilns.
Our solution:
We presented a solution that used a common transmitter (or detector) for most of the toxic gas applications mentioned above and “ticked all of the boxes”. The differences were in the sensor inserts that were specific to each gas. In addition, these transmitters met the new IEC Ex hazardous are requirements plus the SIL rating. The versatility of this transmitter reduces the customers inventory and has enabled various maintenance staff and contractors to become familiar with one common instrument. This was important as less staff were now covering other departments of the plant that they were previously not involved with.
We also offered gas detectors from within the suppliers multi-brand portfolio for the other specialised and difficult applications. As a consequence, we are now enjoying an increased order frequency and value that coincides with an expansion of the chemical plant plus upgrading of older gas detectors elsewhere in the plant.

Customers Challenge: Required bellows sealed globe control valve for dry Chlorine service. The valve design must prove zero emissions to environment due to danger to humans.
Our Solutions:
Offered valve design compliant to Chlorine Institute Pamphlet 6 and Euro Chlor specification (& pressure ratings) per Euro Chlor GEST 89/140. In addition, our valves have an accessible bellows design which allows for total inspection of the bellows, plug and seat for wear, which then can be reassembled easily if no maintenance is required and without consumable parts needed. This is a unique design feature that is not offered by competing brands.
