NTE (NOL-TEC Europe) Oil and Gas Industries:
• Pulverized Material Handling
In oil, gas and petrochemical processes, conveying and dosing pulverized material has a wide range of applications. NTE provides innovative technologies for this purpose tailored based on customers demand and process necessities considering various factors like convey ability, degradation and segregation.
System Components:
> Siloes and storage facilities in which all of provisions for fluidization and inertization are envisaged. The whole process is under monitoring by means of sensors to evaluate temperature and pressure of the system. In case temperature exceeds a certain limit about combustible material like carbon, Nitrogen injection facilities will be put into action to eliminate combustion threat. The silo s are also equipped with level controlling devices. All of silos have a top silo filter on their roof to mitigate dust emission during silo or transporter loading cycles. The silos can be charged both by truck loading device or big bag unloading stations.
> Transporters which are pressured vessels equipped with level and pressure sensors. They receive material from storage silos and inject them into the conveying pipeline. If dosing function is expected from transporter, weighing sensors are envisaged to measure the amount of injected material based on LIW feeder mechanism. The feedback of the system is exerted on a proportioning valve underneath the transporter to control amount of injected material according to the set point defined by the operator.
> Conveying lines which are equipped with revolutionary NTE patent named “Air Assist”. The function of this system is to balance pressure of certain positions of the conveying line with transporter and in case the pressure drop is considerable, compensates this pressure loss injecting compressed air into the pipeline. The advantage of this system is that generally the conveying pressure reduces compared with the other technologies and compressed air consumption is saved considerably.Furthermore,the column of material inside the pipeline is broken into several parts with air packs in between. So in the case system stops due to power failure or any other reason, it will be possible to bring back the system into operation simply pushing the push button without needing to open the elbows to empty the pipeline manually. This problem is very common in pneumatic conveying lines.
> Control System which consists of RIO cabinets to collect field signals to communicate them to the LCP panel under network communication protocols like Profibus. As RIO cabinets are located close to the equipment, weighing boards are also mounted inside them. The LCP is equipped with IO and PLC modules to monitor and control the whole system. The control system is normally based on Siemens technology although it is possible to supply other control systems upon customer’s request.
Applications:
> Catalyst Injection: Like Fluid Catalytic Cracking (FCC) in Oil Refineries
> Additive Injection: Like SOX and NOX abatement Systems, Combustion Supporter Injection, Catalyst Injection
> Pulverized or Granular Material Conveying: PP, PE, LDPE, XLPE, ABS, PVC, Resins, HDPE, Malamine, Urethane, HIPS, GPPS, PET Chips and Fertilizers, Anti-Block Master Batches
