Intecna HYCOR - Model HSI 600 -Pipeline Chemical Dosing System
Regarding PIPELINE DEWATERING OPERATION, it is well known that natural gas hydrates are clathrate compounds in which natural gas molecules are encased in cages of water molecules to form a solid ice-like substance. This innovative process is very helpful for different applications, as mobile sludge dewatering, construction dewatering, and site dewatering technologies.
Hydrate formation can restrict flow and even form a solid plug that can block all production in a short time period. This can cause failures, resulting in equipment damage, and possible injury and risks for workers. It is essential to implement a strategy to prevent or manage hydrates to avoid interruptions of the production cycle in a safe and cost-effective manner.
Methanol or Glycols (MEG – TEG) are normally used to dewater gas pipelines to prevent hydrate formation during the bulk dewatering phase of the commissioning process through stages that involve pigging ,air drying, vacuum drying and nitrogen packing.
In dewatering operations, Glycols are preferred. The problem associated with Glycols derives from their characteristics of Ignition Point (427 °C for MEG and 349° for TEG)
The characteristic of the auto-ignition point, involves the risk of explosion or fire in the presence of an undesired trigger, which can represent a potential danger for the operators and for the plant engineering structures. Due to this reason, pig train must be propelled by N2
INTECNA offers a new solution to this issue and proposes a fluid to be used for the inhibition of hydrates (HYCOR HSI 600) , which has the following characteristics:
- absence of solvents or components that have a point of auto ignition,
- ability to prevent the formation of hydrates as thermodynamic inhibitor,
- control of the corrosion on the pipeline surface,
- possibility of discharge at sea without impact on the ecosystem (PLONOR LIST),
- possibility to use AIR instead Nitrogen for pig train propelling,
- easier handling without risks for the operators.
Achieving the ideal dryness for a subsea natural gas pipeline is a crucial step not only for the commissioning of a pipeline, but also for its subsequent integrity management. Attaining the correct dryness level can help inhibit microbiologically influenced corrosion (MIC) and especially further hydrates formation.
