Drag
reduction is defined as the increase in pumpability of a fluid caused by the
addition of small amounts of an additive to the flowing stream. Drag-reducing
agents (DRA) are also known as drag-reducing polymers (DRP's) which are added
as additives in pipelines that reduce turbulence in a pipe. They are usually
used in petroleum pipelines as they increase the pipeline capacity by reducing
turbulency and allow oil to flow more efficiently. Drag reducing agents are
used in shipbuilding industry, for fire-fighting operations, oil-well
fracturing processes, in irrigation systems, in central heating devices, in
crude oil operations, refined products and non-potable water. However, several
studies are ongoing to implement if drag reducers can help with blood flow in
human systems.
Drag
reducing agent additive function as a fluidifier additive within the crude oil
mass by positively altering the frictional pressure occurring in a pipeline or
other conduit attached. These agents in the crude oil mass modify the
thixotropic characteristics of the crude oil mass to achieve a more favourable
kinematic viscosity without altering the initial composition of the crude oil
mass. This is known as the process of fluidification by molecular dispersion.
Drag reducing agents reduce the turbulence induced drag in the pipeline of the
crude oil mass and rearrange the bonds between atoms in the crude oil without
altering the inherent properties of the crude oil. This decreases pressure in
the pipeline resulting in a higher flow stream at the same pressure. This is a
new approach in chemistry as the alteration in the bonds between the atoms
within the crude oil creates an energy demand which is recovered by the energy
previously lost in the region of the turbulent flow.
According
to the study “Asia
Drag Reducing Agent for Oil & Gas Industry Situation and Prospects Research
Report”, High Viscosity Glue, Low Viscosity Glue and Rubber Latex are
the various product types available in drag reducing agent for oil & gas in
Asia market. Geographically, drag reducing agent for oil & gas in Asia
market is spread across China, Japan, India, Korea, Saudi Arabia and other
region. The leading players in drag reducing agent for oil & gas in Asia
market are LSPI, Flowchem, Baker Hughes, Innospec, Oil Flux Americas, NuGenTec,
Sino Oil King Shine Chemical, DESHI, Qflo, Superchem Technology, The Zoranoc
Oilfield Chemical and CNPC.
Drag
reducing agent in crude oil mass interacts with
varying properties of different crude oil mass such as the type of crude
oil (asphaltic or paraffinic, etc.), composition and pH of the water,
temperature, extent of compression by pressure, dissolved gas, contact time, and
concentration of polar molecules. The drag reducing agents facilitates the
uniform and continuous flow of the crude oil mass to prevent clogged production
wells, flow stream processes, prevent interruption of the production and flow
stream delivery or renewed production of inactive wells.
Drag
reducing agent works as pressure and temperature indicator in pipeline or
conduit, the drag reducing agent does not evaporate because it incorporates
into crude oil mass, it lowers operating costs, environmentally safe, and
produces crude oil profit at lower costs. It was observed that there is
sufficient ongoing crude exploration and extraction within the energy sector
adopting low-cost supplies. The increasing demand and growing population needs
for oil and gas will drive the growth in drag reducing agents in Asian markets
over the next few years.
