Gas Mixer for Analyzer Calibration – Coemi

SME/CEMS

ANALYZER CALIBRATION

UNI 14181

TARGET OF THE PROJECT

Calibration of the analyzers inside the SME/CEMS cabin.

Description of the Application.

La Versalis di Priolo Gargallo (ENI Spa Group) in Siracusa has a chimney for the exhausted gases that come from the combustion oven of the Ethylene plant. An SME/CEMS system continuously measures the pollutant’s level to send its value to the local governing institution in charge to control the pollution level with respect to compliance with AIA prescriptions. Based on the UNI 14181, you have to make, two times per month, a control QAL3. It concerns the linearity verification of each analyzer on 5 points of the full scale: 0-20%, 0-40%, 0-60%, 0-80%, and 0-100%. For each point, we need a gas cylinder with a specific mixture. Gas Blender 100 Series will be used to create the standard test mixture to check the calibration of the analyzers Siemens Ultramat and Oxymat inside the SME/CEMS cabin. In this way, we can use only one gas cylinder (80% of the pollutant in N2) and a gas cylinder of N2 to create all the concentrations we need to check QAL3. This will allow Coemi to:

• Halve the gas cylinder we have to purchase each time.
• Halve the handling of the gas cylinder from the customer’s warehouse to the plant.
• Optimize the intervention time.
• Reduce costs.
• Improve the safety condition of the operators regarding the handling and use of cylinders.

Benefits and Savings.

A traditional method would require at least 2 mass flow controllers, an external control unit, a power supply, and a tubing system, or a massive investment of time in pre-mixed gas cylinders. Indeed Coemi S.R.L. should had purchase much more than 20 liters of mixture gas cylinders.

With MCQ Instruments, the Coemi S.R.L. required only a single Gas Blender 100 Series device and its Software in Pro Version. The simple combination of these two factors has made possible an exponential number of experiments, reducing time, effort, and investments and collecting much more results. In pills:

▼ABOUT THE COMPANY

COEMI was founded in 1974 with the ambition of offering highly qualified electrical maintenance services to the market.
The operational range of COEMI expands rapidly; starting with the development of the industrial area of Priolo Gargallo (SR), one of the largest industrial areas in Europe, up to other related sectors.
The consolidated experience over time has allowed the development and growth of the company by structuring the services offered through six independent but interconnected divisions with the aim of offering a complete and highly specialized service in every aspect.
Over the years COEMI has cultivated its vocation following the evolution of the needs of its customers and the market.
With a constantly updated company organization, today the company provides “turnkey systems” (engineering, assembly and supply of materials), from design to the start-up of electro-instrumental systems and their maintenance.

▼MAIN BENEFITS

Cost Savings.

From 5 gas mixture cylinders to 2. The flexibility of our Gas Blenders reduces consistently the gas mixture cylinder you need.

Gas Mixer vs. Mass Flow Controller.

The GAS MIXER channels it’s more compact than typical flow controller meters and can be specifically calibrated on the mixture to be used.

Time Savings.

More flexibility and time saving to handle only 2 cylinders instead of 5. Halve the handling of the gas cylinder from the customer’s warehouse to the plant.
