Description of the Application.
La Versalis di Priolo Gargallo (ENI Spa Group) in Siracusa has a chimney for the exhausted gases 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 concern the linearity verification of each analyzer on 5 points of the full scale: 0-20%, 0-40%, 0-60%, 0-80%, 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 concentration we need to check QAL3. This will allow 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 safety condition of the operators regarding 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 of 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, efforts, investments and collecting much more results. In pills:
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.
