Delayed Coking Sulfur Water: De-Oiling Data Across Two Purge Stages

2026-11-02

Coke powder carried into the stripping unit is what plugs delayed coking sulfur water systems, and the correction has to start upstream of the tower. This article follows a chemical-free pretreatment built on CDFU cyclonic dissolved-air flotation plus a c

Coking Acidic Water: Four Traits That Break Conventional Oil Removal

2026-11-02

Coking acidic water carries 13.3%-16% oil, heavy coke powder and refractory phenols, and its quality swings hard enough to upset a steady plant. This note separates the stream into the four properties that actually decide equipment selection, then follows

Three Reasons Coalescing Packing Decides the Economics of Your Oil-Water Separator

2026-10-30

Coalescing packing sits at the heart of every oil-water separator, and upgrading it is usually cheaper than replacing the vessel. This article sets out three value levers: a 150% larger specific surface area that lets fine droplets collide and grow, built

From Ammonia Liquor to Reuse Water: Reworking Coking Acidic Wastewater With CDFU and KHC

2026-10-30

Coking acidic wastewater gathers excess ammonia liquor, phenol-cyanide streams, scrubbing water and desulfurization waste liquor into one difficult feed. Conventional pretreatment is costly and prone to blockage. The SINOKLE flow of coarse filtration, CDF

Comparing the Main Options for Petrochemical Oily Wastewater: Gravity, Centrifuge, Adsorption and Coalescing

2026-10-30

Every tonne of refined product leaves 0.5-1 t of oily wastewater with high salt and COD in the thousands of ppm. Gravity separation, centrifuges and adsorption each carry known drawbacks, while chemical dosing adds impurities and biology cannot tolerate h

Three-Low Reservoirs and Polymer Flooding Are Reshaping Produced Water: Where CDFU Fits

2026-10-30

As China develops more three-low reservoirs and expands polymer flooding, produced water becomes more viscous, more emulsified and harder to reinject safely. This article links the global energy outlook to oilfield water quality, explains why single-proce

Two Oxidation Pathways, One Bottleneck: Why Ozone Alone Falls Short and What Catalysis Adds

2026-10-30

Ozone attacks pollutants along two pathways: direct reaction as an electrophile or nucleophile, and indirect decay that generates hydroxyl radicals. Selectivity, incomplete mineralisation, low solubility and acidic by-products still limit ozone-only proce

Coking Acidic Water Stripping Starts With De-Oiling: A CDFU Plus KHC Skid That Passed a 72-Hour Test

2026-10-30

Acidic water from delayed coking carries coke powder, severely emulsified oil, sulfur, ammonia nitrogen and phenol, and sending it straight to a stripper invites tray plugging and unit shutdowns. A purely physical skid built around CDFU cyclonic dissolved

Landfill Leachate Without Membranes: An Ozone Oxidation Route Built on CDOF and CDFU

2026-10-30

Landfill leachate carries hundreds of organic pollutants, heavy metals and high ammonia loads, and biological processes alone rarely reach today's discharge limits. The SINOKLE route pairs the CDOF and CDFU units with a biological denitrification reactor

When Polymer Flooding Fouls Your Filters: How KFM Active Media Handles Oilfield Wastewater

2026-10-30

Polymer flooding raises viscosity and stabilises emulsified oil in oilfield wastewater, and conventional filter media foul quickly under this load. The KFM active filter media filtration system from SINOKLE uses a modified silicate matrix with a permanent
