Valve Controller Helps Chinese Chemical Plant Save $40,000 in Repairs and Downtime
After Emerson Process Management replaced existing valve positioners in the Shanghai Ethylene Cracker Complex (SECCO) with Fisher FIELDVUE DVC6200f digital valve controllers, the SECCO plant gained better control, production efficiency, and uptime – and $40,000 in annual maintenance savings.
SECCO is the largest integrated chemical facility in China. The complex includes a naptha-fed ethylene cracker and ten downstream derivative plants with thousands of control valves of different brands, types and sizes. Temperature fluctuations in the process caused high variability in the end product which, combined with vibration of the pipeline, often led to damage and replacement of the positioners on these valves. After SECCO engineers and Fisher valve specialists from Emerson discussed ways to address this problem, SECCO decided to replace the facility’s positioners with Emerson’s Fisher FIELDVUE DVC6200f digital valve positioner.
The DVC6200f offers linkage-less, non-contact position feedback to reduce vibration-induced problems as well as diagnostics and FOUNDATION fieldbus communication to promptly alert operators of potential valve
problems. The instrument is easily mountable onto any valve, which was especially important in SECCO’s case. In addition, achieving high process reliability and performance is possible because of the DVC6200f’s diagnostic capability to predict problems before they occur, allowing operators to take pre-emptive action to minimise process variability or avoid a plant shutdown.
After installation, operations in the facility were enhanced with better stability and control. Production efficiency improved, while waste and rework were reduced. Valve performance is more reliable, and uptime has increased because of less frequent valve failure and scheduled maintenance. SECCO has saved an estimated $40,000 annually by eliminating the frequent replacements of positioners a well as maintenance, labour and potential production loss.

R-1 Pressure Sensor now Fully CO2 Compatible
Due to its environmental compatibility, CO2 is increasingly establishing itself as a refrigerant in industrial applications. Thus, the model R-1 pressure transmitter from WIKA (Germany), tailored to the needs of
refrigeration and air-conditioning technology, now also offers complete compatibility with the requirements of CO2 refrigeration plants.
With this instrument, designed specifically for refrigeration systems, pressures from 100 to 160 bar,
which are typical for CO2 applications, can also be covered. The hermetically welded measuring cell reduces the likelihood of leakage to zero. Its thin-film sensor, made using sputtering technology, distinguishes itself with its high long-term stability and excellent overpressure safety.
The compact R-1, with its robust design and gasket-free process connection, has been proven in applications with traditional refrigerants for a long time. In addition to its high medium temperature
range and its excellent performance, the transmitter features an attractive price/performance ratio. Reader Reply Card No 203

Highly Accurate - Reliable - Easy to Use
KOBOLD (Germany) introduces the new electromagnetic flow meter model DMH with a standard accuracy of 0.3% of reading ± stability of zero.
The new developed, microprocessor-controlled converter UMF2 guarantees highest accuracy and is easy to operate via its alphanumeric backlit LCD terminal with 6 keys, plain text response, and plausibility check of your entries.
Empty-pipe detection, coil current monitoring, and plain text error messages guarantee full control over sensor and measuring point at any time.
Pulse, status, and current outputs as well as HART communication are standard features, all of them electrically isolated, of course.
Lining materials such as hard rubber, soft rubber, and PTFE are available, as are Rilsan and Wagunit, which are particularly suitable for hygienic areas and water pipes.
As usual, KOBOLD's partner Heinrichs offers a wide range of standard and special electrode materials, including Hastelloy, platinum, and tantalum. To simplify installation, optional grounding electrodes in addition to the grounding flange are available.
Cost-conscious customers will appreciate the optional LED status display as an alternative to the alphanumeric LC display.
