Description

Services

Knights Nitrogen specializes in providing Industrial nitrogen Services for a wide variety of Services throughout Alberta, Saskatchewan and Manitoba. Whether it is a planned or emergency outage, Knights will be ready to mobilize experienced crews and equipment to your site.

Industrial Plant and Process Services

Purging and Inerting- Nitrogen purging is easily adapted to any process installation. Different methods are used depending on the type and shape of the equipment to be purged and the location of the purging inlets and outlets.

  1. Displacement purging. This method is used for equipment with simple cross sections such as piping.
  2. Pressurization/Cycle purging- This method is used when conditions do not permit a sweeping action of nitrogen through the vessel
  3. Dilution Purging- Nitrogen partially mixes with the gas to be purged out, and then the mixture exits through a outlet located as far as possible from the inlet.

Catalyst Support- Accelerated cool downs using cold nitrogen at high flows on catalyst beds and vessel walls. Nitrogen is also used to support catalyst removal after the beds have been cooled. A continuous stream of nitrogen keeps oxygen away from pyrophoric catalysts and preventing temperature rising and creating a explosive atmosphere.

Process Drying-Nitrogen has a dew point of -70 Celsius. With pumping hot nitrogen this will remove moisture and air from process units. 

Blanketing- Nitrogen is used to blanket lines ,vessels or tanks with product depending on the maintenance needed. 

02 Freeing- After maintenance is completed, nitrogen is used to 02 free the process piping and vessels and obtaining 0% O2 before the product is introduced. 

LEL purging- Nitrogen is used to lower LELs for piping and vessels and towers by purging with flow purging or cycle purging. 

Outages and Commissioning- Usually outages are planned for maintenance and nitrogen is pumped at one location throughout the facility. 

Leak detection- After maintenance is completed, nitrogen is used to check all connections and flanges to ensure systems are safe for start up

Pipeline Services

Product displacement- Using nitrogen to push pigs through line to empty line for maintenance or abandonment. 

Line dewatering- Nitrogen is used to dewater line after hydro test, by propelling multiple pigs to remove all water and moisture ILI Tool runs-a nitrogen blanket is put on the pipeline then the smart pig is propelled by nitrogen at a desired speed to obtain data for the client. 

Gauge runs- Gauge run pigs are sent before the smart pig to make sure the pipeline is free of damage or debris before the ILI run. 

Inhibitor Tool runs- multiple pigs are put into the pipeline with inhibitor batch mixed and then propelled by nitrogen coating the pipeline with inhibitor. 

Blanketing- Nitrogen is used to blanket pipelines for several different applications Maintenance, abandonment. 

Pipeline Drying- hot nitrogen is pumped throughout the line with or without pig to remove moisture and obtain a dew point of -45 Celsius to prevent hydrates forming. Usually on new construction tie ins. 

Pressure testing- Nitrogen is pumped to obtain a pressure test on new or existing lines.

Downhole Services

Coil tubing Operations- Purging coil tubing, Clean outs, Abandonments, Drill/ Mill outs. 

Well Cleanouts/Kick arounds- Rig or Rigless, nitrogen can be pumped to lift fluids or to reduce the weight of a hydrostatic column of fluid. 

Pressure testing- Pumping nitrogen into wells with hydrocarbons to prevent explosive atmosphere. 

Nitrified Acid Stimulation- is the technique designed to remove well bore formation damage which has occurred during the productive life of the well without causing damage with kill fluids . 

Abandonments- Providing nitrogen for nitrogen blanketing or cleanouts in wells with hydrocarbons in order to set plugs and abandon well. 

Well integrity testing- Using nitrogen to pressure test wells and connections. 

U-Tubing- Pumping nitrogen down the tubing or annulus and returning up the annulus or tubing. 

Stuck Drill Pipe- pumping nitrogen to lower the hydrostatic head and allow for freeing of the drill pipe when the drill pipe is differentially stuck. 

Underbalanced Drilling- is a procedure used to drill oil and gas wells where the pressure in the wellbore is kept lower than the static pressure than the formation being drilled.

Equipment

Nitrogen Pumps

These tandem trailer units are equipped with a liquid nitrogen storage tank, non fired vaporizer/ heat exchanger, and cryogenic pumping equipment all operated from Deck engine with dual 100 gal fuel tanks. Operating independently with a C18 deck engine (800 HP) , there is no chance of any Nitrogen supply interruptions due to the engine derating or extreme heat caused by regeneration of a DEF system, also a huge safety point for those working under a Nitrogen blanket during a Catalyst change out. All controls and valves actuated from control cab.

Features:

  • Delivering gaseous nitrogen with Variable temperature -25 to +65 Celsius with overpressure and low temperature trips.
  • Flow rate 0-85 M3/ Min
  • Pressure 0-70000 kpa
  • 7000 M3 storage capacity on board
  • 25 meters of Integral Iron on board and 90 meters of high pressure hose on reel
  • Manifold set up for ease of setting up multiple lines to tie in points.
  • Pressure relief valve installed in discharge line.

 

Nitrogen Transport Bulkers

Knights Nitrogen providing Nitrogen transports to support stand alone pumps or to assist larger jobs. These bulkers have the ability to transport and transfer large quantities of liquid nitrogen. Our experienced team will organize ahead of schedule to have extra product on site to reduce pump downtime waiting on product to save costs and time to the client. Tandem Nitrogen bulkers available for tight locations and Tri-dem Nitrogen bulkers, which larger bulker capacity eliminates multiple loads brought in to site. Queen bulker can be delivered and filled on site for extra capacity.

Capacity: Tandem- 17000 M3 Tridem - 23000 M3 Queen - 55000 M3

 

Nitrogen Generating Units

Single or dual feed oil free compressors supplying to Nitrogen bundle with option of nitrogen booster. Air Drying ,Nitrogen purging depending on purity requirements . Multiple set ups available please contact for more info
