Coating Applications for Upstream Oil and Gas

Improve Sampling Reliability, Stability, and Response  

Get the Performance You Need and the Quality Your Customer Demands 

SilcoTek® coatings like SilcoNert® and Dursan® make critical flow paths inert, assuring you're getting the process data and product quality you need.  Well sampling and downstream sampling using Teflon® tubing and PTFE coatings can experience porosity, delamination, and tubing failures in sample transfer heat trace tubing applications.  Our inert, corrosion resistant coatings line tubing surfaces to provide a high temperature, high durability surface.  The perfect solution for challenging refinery, petrochemical and process environments.

The benefits of an inert and high reliability flow path include:                                                                                 

  • Faster response, save time and improve process control                                                                              
  • Improved sensitivity and detection of sulfurs and mercury.  More accurate well assessment and product quality assessment.                                                                             
  • Easier system calibration                                                                             
  • Improved corrosion resistance, durability and reliability
                                                                 
  • Consistent performance for improved regulatory compliance

Coating Applications for Upstream Oil and Gas.

SilcoTek® coatings are used in downhole sampling, flare sampling, CEMS and sample transfer systems to prevent interaction of the test sample or product with the flow path surface.  Our inert coatings like SilcoNert® and Dursan® prevent adsorption, reactivity, and improve surface corrosion resistance.  Applications include:

 
  •   Environmental Sampling & Flare Sampling
  •   Downhole Sampling 
  •   Odorant Testing
  •   Produced Water Management
  •   Corrosion Control

An inert flow path is a critical factor in achieving consistent low level detection of reactive compounds like hydrogen sulfide as well as maintaining a reliable corrosion resistant surface.  SilcoTek CVD coatings achieve the lowest detection limits for many industry standards relating to oil and gas sampling. 

Achieve the lowest level of detection for:

 
  •   H2S, Mercaptans, Sulfur
  •   Mercury
  •   VOCs
  •   NOx and SOx
  •   More
   

SilcoTek coatings also help to maintain flow path probe, and downhole sampling durability by improving corrosion and wear resistance.  Use SilcoTek coatings wherever corrosion is a problem:

 
  •   Stack and pipeline probes
  •   Small heat exchangers
  •   Valves & fittings
  •   Tubing
  •   Reactors 
  •   Sample cylinders and downhole samplers
  •   Produced water equipment
   

  

Refinery, Petrochemical, and Process Sampling Data

First we'll compare the performance of SilcoNert in sulfur analysis applications.  Reactive compounds like hydrogen sulfide (H2S) get stuck in analytical systems, causing significant delays in response time.  SilcoNert® coated surfaces allow compounds to travel through critical flow paths unimpeded, offering near-real-time response and improving lab productivity.  Comparative data from CONCOA (below) show a nearly 10x improvement in response time for a SilcoNert coated flow path (blue line) compared to an uncoated stainless steel system when sampling part-per-million and part-per-billion level hydrogen sulfide.

SilcoNert 2000-coated sample components provide excellent stability for mercury samples, even after several weeks of storage.  The uncoated stainless steel cylinder (black line, below) quickly adsorbs mercury compounds, making reliable sampling and calibration a challenging task.  The user may spend unnecessary time and money getting an accurate mercury test result.   The SilcoNert-coated cylinder (green line) maintains an inert surface which improves mercury stability even after 2 months of storage.  This promotes a reliable and accurate sampling environment, saving the operator time and money.

Need an inert surface that's durable and corrosion resistant?  Dursan offers superior performance and durability, making it an ideal coating for sampling in challenging environments.

The uncoated tubing (below left "A") retains methanol, resulting in unreliable and slow calibration and testing.  The SilcoNert coated tubing (right "B") retains very little methanol, resulting in fast response and accurate test results.  This enables field testing stations to provide consistent results and avoid regulatory compliance issues.
