Oil & Gas Plant

OEI offers innovative and performance driven magnetic filters that enable increased efficiency and reduced plant operating costs. With applications on all facility rotating equipment, OEI protects chemicals,hydraulic fluid, process water, pumped fluids, compressed gases, lube oils, amine, coolantand compressed gases from the most damaging wear contamination.

Featured Case Study

Proven Result: Improved Dehydration Efficiency

Customer
ENI Drilling Company

Location
Adriatic Sea, Italy / 2015

Equipment
Offshore Gas Platform

Application
Glycol Dehydration

Problem
Contamination entering a 3000-7000 L glycol reservoir from a 32 km pipeline had high levels of contamination as a result of pipeline corrosion. The contamination would degrade new glycol, and reduce it’s ability to cool and remove moisture from gas. Corrosion of the carbon steel piping would cause contamination build-up during transmission and storage.
The glycol system was unmanned and required a low maintenance filtration solution with minimal change-outs. During the dehydration phase, if the temperature of the glycol is volatile (this occurs when high levels of iron are present) the likelihood of vaporization loss is increased, resulting in lost production.

Solution
Install an OEI magnetic filter scrubber after the reservoir to improve glycol quality.

Results
Analysis of contamination collected on the magnetic element showed 74% non-ferrous particles and 26% ferrous.
The glycol quality was significantly improved with minimal maintenance requirements.

ENI Glycol Gas De-hydration Improvement

Contamination entering a 3000-7000 L glycol reservoir from a 32 km pipeline had high levels of contamination as a result of pipeline corrosion. The contamination would degrade new glycol, and reduce it’s ability to cool and remove moisture from gas. Corrosion of the carbon steel piping would cause contamination build-up during transmission and storage. The glycol system was unmanned and required a low maintenance filtration solution with minimal change-outs. During the dehydration phase, if the temperature of the glycol is volatile (this occurs when high levels of iron are present) the likelihood of vaporization loss is increased, resulting in lost production.

Screw Compressor Lube Oil Analysis

The challenge was to prevent premature failure of a screw compressor in Pioneer Natural Resources’ crude oil vapour recovery unit. The screw compressor components (bearings, seals) were wearing due to inadequate filtration the lube oil for particulate down to 4 microns and below.

Pioneer Natural Resources 3512 New Engine Lube Oil

The challenge was to clean new engine lube oil on a 3512C CAT engine to a level that exceeds the ISO fluid cleanliness standard 18/16/13. Daniel Stoye, Maintenance Manager with Pioneer Natural Resources wanted to extend engine component life so that maintenance intervals could extend to align with quarterly inspections.

Burlington Resources Glycol Pump Protection

The challenge was to reduce ferrous particles in the system, as they led to pump failure, and conventional filters were not effectively removing the contamination. Maintenance Manager for Burlington Resources wanted to prevent pump failures and reduce contamination down to 4 microns and below. 

Alliance Pipelines’ Heat Recovery System Protection

The challenge was to reduce high levels of contamination in the pentane waste and heat recovery systems of Alliance Pipelines’ heat recovery system. The contamination was prematurely wearing pumps, seals, and piping components. This system operated at 350 gallons per minute with a viscosity of 0.24CP at 20 degrees F.

Protecting Momentives Chemical Plant Mag Drive Pumps

The challenge was to reduce high levels of contamination causing premature failure of the pumps and seals. The contamination was a result of erosion and corrosion of the piping caused by the dangerous process fluid Trimethoxy(methyl)silane (CAS number 1185-55-3). 

Protecting Unison Solution’s Methane Gas Compressors

Conventional filters were failing and unable to protect the compressors used to extract and compress methane gas from refuse landfill sites. The failures occurred as a result of sulfuric gas mixed with the methane reacting with the metal skin of the disposable filter.

Protecting Taminco’s Magnetic Drive Pumps

Taminco operates many magdrive pumps that pump highly corrosive and toxic liquids. The pumps are supplied by companies like Sihi, Dickow, and Klaus Union. The pumps were failing within 6 months due to contamination between the wetted end magnetic drive, and the protection or containment shell. Taminco was enduring significant operating costs associated with downtime, unscheduled maintenance, and parts replacement of bearings and containment shells.

OEI magnetic filters are designed for 95+% efficiency: they are optimized for fluid viscosity, flow volume, flow rate, temperature, mobility, and mounting requirements.
