Oil & Gas

Mercury is a common contaminant in crude oil, requiring removal to prevent catalyst poisoning, corrosion, and environmental risk. DrM filtration systems are used to clarify slurry-phase adsorbent beds and remove fine mercury-laden solids prior to downstream refining or storage. Their fully enclosed design supports safe handling of hazardous media, while automatic operation and dry cake discharge minimize waste treatment demands. These systems help extend adsorbent life and ensure compliance with safety and emissions regulations.​

Fluid catalytic cracking (FCC) units generate fine catalyst particles that must be removed from slurry oil or recycle streams to protect downstream equipment. DrM filters provide effective separation of catalyst fines in a closed, automated system, eliminating the need for disposable cartridges or manual handling. Their high efficiency and low maintenance design reduce fouling in heat exchangers and improve overall unit reliability, especially in heavy or high-solids process streams.​

Amine-based gas treatment systems rely on solvent recirculation loops to remove H₂S and CO₂ from sour gas. Over time, contaminants such as iron sulfide, degradation byproducts, and corrosion particles accumulate, causing foaming, corrosion, and reduced absorption efficiency. DrM filtration systems are used to clean lean amine streams via a 10–20% slipstream, effectively capturing these fine solids. The enclosed, self-cleaning filters operate with optional precoat and dry cake discharge, minimizing solvent loss, water use, and operating cost, especially valuable for remote or arid site locations.​

Monoethylene glycol (MEG) is injected into subsea gas pipelines as a hydrate inhibitor and must be continuously regenerated for reuse. DrM filters are installed in MEG regeneration units to remove scaling compounds, corrosion particles, and salts such as CaCO₃, Mg(OH)₂, and FeS. These filtration systems handle wide variations in rich MEG composition and solid load while maintaining stable performance. The ability to wash the filter cake ensures minimal MEG loss, supporting efficient recovery and reducing chemical demand in upstream oil and gas operations.​

Pipeline pigging dislodges built-up deposits such as waxes, corrosion products, and scale from the inner pipe walls. The resulting pigging water is typically laden with fine solids and chemical residues that must be removed prior to discharge or reuse. DrM filtration systems are used to clarify this intermittent, highly contaminated stream efficiently, even under fluctuating solids loads. Their ability to operate with filter aid and perform automatic dry cake discharge makes them ideal for pigging loop integration, reducing waste volume and improving handling safety.​

Produced water extracted along with oil and gas often contains sand, corrosion products, chemical treatment residues, and insoluble salts. DrM filtration systems offer a reliable, automated solution for separating these suspended solids before reinjection or disposal. They can replace conventional treatment trains involving settlers, hydrocyclones, and cartridges, achieving high clarity (down to ~0.5 μm) in a single enclosed unit. The option to use filter aids and discharge solids as dry cake simplifies waste handling while minimizing operator intervention and reducing HSE risks.​

Sulfur recovery units (SRUs), such as Claus or tail gas treatment processes, often generate slurries containing elemental sulfur, catalyst fines, or other byproducts. DrM filters are used to remove these solids from liquid sulfur condensate or amine streams, ensuring clean product recovery and reducing fouling in downstream heat exchangers. Their corrosion-resistant design, automated discharge features, and ability to handle both low- and high-viscosity fluids make them a reliable option in sulfur recovery and sulfur-handling circuits.​
