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.


> 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
