Pipeline maintenance & Cleaning

Chemlogic’s pipeline cleaning and maintenance chemistries are based on years of pipeline debris analysis, single application – single product development, and the essential efficacy studies. Of course, when coupled with our customer’s experienced field services, success is imminent. How do we produce successful results?

Chemlogic’s determined technical development personnel will develop a single product “rifle focused” to perform based on numerous proprietary factors. Other suppliers offer mass produced products that commonly slow the cleaning project turnaround, increase the number of pig runs and product use rates, and in the end, benefits only the seller.

Chemlogic evaluates pipeline records, previous pig trap analyses, along with any pigging debris samples that we forensically analyze utilizing various diagnostic analytical procedures to determine what the debris is composed of and how it formed. We then process the data in our comparative pipeline debris database which currently consists of >500 debris analyses. Once cross-referenced, we verify various chemistries for cleaning and dissolution efficacy. We either formulate a new chemistry based on requirements or adjust a current chemistry for increased effectiveness. In doing so, Chemlogic develops your debris analysis report and recommendation for your perusal.

What does our improved process for product development and selection deliver to you?

When Chemlogic is allowed the opportunity to review previous analyses records or reports, we’ll have enough intelligence to focus the precise existing chemistry and have it onsite within hours of the request. 

And, if given the opportunity to analyze a debris sample, Chemlogic will either develop a specialty formulation designed specifically for the debris matrix or find the best existing product solution available.

The recommendation and effectiveness reports, as well as the novel chemistry, will be available in 12 – 48 hours for rush shipments.

When you employ a chemistry designed specifically for the debris matrix that will be encountered, you can reduce project turnaround time by up to 50% or greater. Developing or choosing the right product means fewer, and more effective pigging runs. It also produces less waste to dispose of and faster inspection for Federally mandated records.

Correctly cleaned pipelines provide for an improved and speedier ILI run ultimately saving on regulatory expenditures. And, clean pipelines have higher throughput efficiencies, reduced compression issues, easier follow-up maintenance pigging, and ultimately mitigates the likelihood of redeposition.

DehySolv™ 100 Chemlogic DehySolv™ 100 is a novel dehydration humectant that is based on chemical absorption and physical laws that support the unique composition of polyhydric alcohols, diols, triol, and associated glycols which absorb water rather than mix with water. The compound absorbs up to 100% of its weight in water leaving surfaces water break-free and dry. Unlike miscible methanol, polyhydric alcohol absorb water in the gas stream, as well as the free water standing in the line. There is no serial dilution of water. When the chemistry is injected and pigged through the line, the dense solution is easily separated leaving pipeline contract gas due to its desiccating properties. In contrast, the low flash point compound commonly used, methanol, remains miscible in the water and passes easily in the vapor phase without being desiccated and dried.

DehySolv™ 102-CI Like DehySolv™ 100, DehySolv™ 102-CI is a novel dehydration humectant that is based on

chemical absorption. The compound was designed with a pipeline corrosion inhibitor to treat the internal pipe wall and leave a protection film to mitigate corrosion. DehySolv™ 102-CI can be used to dry hydrostatically tested lines, while leaving a molecular inhibition film that is persistent and long-lasting (depending on pipeline flow and contents).

Hydrogen Sulfide (H2S) is a common impurity found in oilfield waters and natural gas. Operating problems caused by H2S can include severe corrosion and fouling, injection well plugging with iron sulfides and safety problems related to H2S gases. Most pipeline companies require sales gas to be substantially free of H2S. Chemlogic IL-1955 quickly and effectively removes H2S without creating solids or other operating problems. For H2S removal from production waters, IL-1955 is applied at the rate of 100 ppm for every 5 ppm of dissolved H2S present in the water. For removal of H2S from natural gas, IL-1955 can be injected into the gas stream at the wellhead or contacted with the gas in a contactor tower. For this application the following relationship can be used: Lbs. of IL-1955 Required per Day = ppm H2S in gas x MMCF/day x 0.56.

The injection rate is normally 30 – 90 ppm depending on the severity of the foam problem.

Hydra-Hib™ 630 Avoidance of hydrate formation is preferable to removal of existing hydrates from an economical view and safety concerns. To achieve this, the hydrate formation process can be influenced on several points: (a) dehydration of the gas before transport, (b) controlling of pressure and temperature during the transport, (c) use of thermodynamic hydrate inhibitors, THI (methanol is the most common), (c) use of kinetic hydrate inhibitors, KHI, (d) use of antiagglomerate chemistry, AA, (e) use of novel, combinatorial formulations of THI, KHI, and AA modifiers. Hydra-Hib™ 630 is a combinatorial thermodynamic, kinetic, and anti-agglomerate hydrate distorter for low to high chloride brines (up to 75,000 ppm chlorides). When compared to methanol, which generally takes up to 30% by weight of the water present in a system,

Hydra-Hib™ 630 requires less than 10% of the amount of methanol normally used. And, most importantly, Hydra-Hib™ 630 works when methanol or glycol often fail to prevent hydrate formation…even at the highest rates possible. Hydra-Hib™ 630 will lower hydrate inhibition cost by 50 – 90% while improving gas throughput.
