Pipeline Pigging TRANSMITTER
Pipeline Cleaning Online cleaning, removal of dust, liquids and sand Wax, paraffin and asphaltene removal from crude and fuel oil pipelines De-oiling, for pipelines that will be prepared for other products De-rusting of oxygen- and product pipelines Inhibitor pig runs for H2S pipelines
Pipeline I nsitu Coating Pipeline Rehabilitation Services Process: In-Situ coating application whereby a two compound Epoxy coating will be applied to inside pipe-wall between pigs. This will allow several kilometers of pipeline to be coated without cutting the pipeline. Uncoated Coated
Pipeline Displacem ents Nitrogen can be used to pig and displace pipelines using the expansion capacities of liquid nitrogen. Flaring Products can be send to storage facilities or through filters in other pipeline sections or just vented off through flares, Filters Tank storage product NITROGEN PRODUCT SILENCE SILENCER R
Nitrogen Services Reactor Cool-dow n Services Are developed to accelerate the cool-down process minimizing down time prior to catalyst change and lower the reactor entry temperature for safer and faster work. Basic procedures: - Using LN2 to cool down the recycle gas (most efficient). - Once trough method.
Nitrogen Services After the initial cool-down to temperatures of 150 – 250˚c the accelerated cooldown process will take over and the cool-down rate will be increased using cold Nitrogen gas to temperatures < 40˚c Nitrogen can also be used for the hot stripping of hydrocarbons from the catalyst.
Nitrogen Services Helium Leak Testing Services Pressurizing process systems to 95% of the PSV setting using Nitrogen with 1% Helium as a tracer. Flanges will be taped off and checked for leaks.
Nitrogen Services Nitrogen Foam I nerting PRS ’s Nitrogen foam in-erting is a simple yet effective process that enables hot work to be carried out on hydrocarbon handling systems in complete safety. The Nitrogen foam is injected into a process system at a low point and allowed to completely fill the vessel and pipework, rendering the internal atmosphere inert. On completion of hot work operations, the Nitrogen foam degenerates into small amounts of water, surfactant and gaseous Nitrogen.
Nitrogen Services Typical foam in-erting applications include vessel and pipework modification and / or replacement, hot cutting and system de- commissioning. All components of nitrogen foam are biodegradable and non-bio accumulative.
Nitrogen Services Pipe Freezing Services Pipe-freezing is an essential tool in the maintenance of all types of liquid storage, process and transfer plant. The range of applications in which pipe-freezing can provide cost effective solutions is both extensive and diverse, from a small domestic water pipe to a huge oil pipeline, from a hospital heating system to a brewery bulk storage system, the freeze can be applied quickly and the results are reliable. TYPICAL FREEZE PLUG SET-UP ALLOWING TEMPORARY PIPELINE ISOLATIONS.
Nitrogen Services Under Ground Tank & Line Leak Testing The portability and light weight of the PRS heli-test equipment (varian PHD-4) plays a major role in this application. Underground pipelines and storage tanks (ugst) are pressurized with Helium which, due to its high mobility, can escape through small leaks and migrate to the surface. There it can be easily detected by the phd-4.
Chem ical Cleaning Chemical Cleaning In addition to the standard cleaning methods, PRS International offers a broad range of chemical cleaning services for pipelines, process systems in the process industry and power plants. Using solvents and/or surfactant bases cleaning chemicals are more effective than the traditional mechanical cleaning methods. Chemical cleaning is widely used for commissioning and de-commissioning of pipelines and process plants to increase productivity (throughput) and efficiency, to improve inspections results, to maintain the quality of the product. In pipelines the use solvents and/or surfactant based cleaning chemicals are more effective than the mechanical cleaning using only pigs.
Steam & Airblow Services Steam And Air Blow ing Services Steam blowing and air blowing are basically alternative techniques used during the commissioning of new steam raising plant. They are performed to ensure that potentially damaging debris is removed from the steam lines before the steam is admitted to equipment that may be damaged by such debris, in particular steam turbines. Typical steam -blow operation in progress
