Chemical Cleaning

In addition to the standard cleaning methods, PNS Chemical Solutions offers a broad range of chemical cleaning services for the pipeline and process systems. The chemical cleaning is typically used to remove deposits like scale, corrosion, waxes, paraffin and asphaltene sediments in pipelines. The use of solvents and/or surfactant based cleaning chemicals are more effective than the mechanical cleaning using only pigs.


Chemical cleaning is widely used for commissioning and de-commissioning of pipelines and process plants, to increase productivity (throughput) and efficiency, to improve inspection results, to maintain the quality of the product. In pipelines the use of solvents and/or surfactant based cleaning chemicals are more effective than the mechanical cleaning using only pigs.

Typical systems to be chemical cleaned are;

  • Turbine piping


  • Product pipelines (incl Oxygen lines)


  • Oil & Gas pipelines


  • Process piping


  • Process Towers (p.e. glycol and Amine)


  • Heat exchangers


  • Heat transfer lines.


Products:

The majority of the products used by PNS Chemical Solutions are environmentally friendly and biodegradable, this will minimise the cost for waste disposal.

These products provide a cost effective and easy- to-use approach to pipeline and system cleaning. PNS Chemical Solutions is utilizing new chemical cleaning technologies to improve the cleaning operations of oil and gas pipelines.

The new products are highly concentrated blends of biodegradable surfactants and synthetic solvents capable of wetting and removing the most tenacious deposits encountered in oil and gas pipelines.

De-contamination for TAR’s

PNS Chemical Solutions offers a range of chemicals that can be used for the decontamination process during the T urn Arounds.

Turnarounds are expensive in lost production, so it will always be cost-effective to plan thoroughly, optimize the scope of work to be done, and optimize the methods of working. Unit decontamination, at the start of the turnaround, forms a major part of the turnaround costs and total time. Many maintenance tasks cannot even start until decontamination is complete.

Most current technology in process unit decontamination is to eliminate the previous practice of decontamination based on “time criteria” and rather opt for the “fact based approach”. In addition, chemical cleaning is more and more implemented as the main procedure in the decontamination strategy.

The fact based monitoring approach can help the user save time and money. It will gain


  • Reduced turnaround time, form several hours to even days


  • Improved readiness for maintenance work


  • Improved safety


  • Improved environmental performance
