Contaminant Analysis
SECORP Onsite Contaminants Analysis provides speciality services for on-line gas contaminant measurement and analysis to our clients ranging from Oil and Gas, petrochemicals, power generation and downstream industries. Our specialist are comprised of skilled, well-trained and competent engineers that have years of expertise in filtration and separation systems application.
We have in-house expertise that can perform sole source on-line analysis for gas contaminants and on-site analysis for gas streams including fuels, natural gas, CO2, H2S, ammonia, etc. SECORP applies field-proven and proprietary methods at the client’s live gas pipeline to identify, measure and quantify major contaminant categories in gas stream; free liquid carryover (slugs, foams, hydrocarbon), aerosols (fine particulate and liquid / hydrocarbon vapor), and solid particles (iron oxide, iron sulphide, elemental sulphur, sand, etc). Our services applied isokinetic method of gas sampling which provide the best accurate analysis result. The analysis activities will be performed under the actual, live gas processing condition.
Our On-Line Analysis Speciality
1. To perform filtration and separation performance verification, measuring contaminants upstream and filtration separation systems such as KO vessels, gas scrubber, slug catchers, glycol dehydrators, heater, gas coalescers and gas conditioning skids.
2. Process troubleshooting to determine whether a failure of a system was due to contaminants presence in the gas. To determine the gas cleanliness level upstream of critical rotating equipment and process systems such as turbo compressors, gas turbines, molecular sieve beds, catalysts, fuel gas, dry gas seals and instruments.
3. Provide technical recommendations and solutions via troubleshooting request. Our sampling has frequently used as part of client’s RCFA looking for gas quality level.
Our Special Test Protocol
1. Free Liquid Contaminants Measurement. As a liquid contaminant increases in volume in gas processing piping, it will start to travel along the sides and bottom of a gas pipeline as a liquid stream. SECORP free liquid measurement protocol utilizes a high efficiency gas coalescer and gas flow meter / totalizer to sample at isokinetic condition. Our special equipment was designed to collect the free liquid that travels along the pipeline wall as well as the liquid that is entrained in the gas stream. Solid collected on the element can also be qualitatively analysed with a microscope for size and general content. Expected result from this analysis in term of PPM wt, gals/MMSCF or Litres/day.
2. Solids Analysis. SECORP solid analysis utilizes a high-pressure filter disk holder assembly to isokinetically sample and collect suspended solid contaminant in a midstream of a gas pipeline. Particle collected on the filter disk can be microscopically analysed to provide a particle size distribution. Result gather from this analysis such as Particle Size Distribution, PPM wt, mg/MMSCF, grams/day.
Our additional analysis provides:
- Laboratory testing for contaminants compositional analysis.
- AAS for mercury detection
- Inductive Couple Plasma (Optical Emission Spectroscopy (ICP-OES)
- GCMS for hydrocarbon (C6-C40, Organic Compound)
- GCMS for glycol screening
- FTIR (Functional Group)
- XRD
- SEM-EDX (in-organic compound / elements)
