● Global market: Magnetic separation equipment for chemicals is growing at 5.8 % CAGR and expected to reach USD 1.2 billion by 2027.
● Key segments: Fine chemicals, petrochemical catalysts, agrochemicals, pigments, and specialty polymers.
● Regulatory push: REACH, FDA 21 CFR, and ISO 9001 increasingly demand metal-inclusion ≤ 10 ppm.
● Process trend: Continuous-flow plants, high-purity APIs, and closed-loop solvent recovery.
“Removing just 1 ppm of ferrous contamination can boost catalyst selectivity by 3–5 % and extend fixed-bed life by 15 %, saving USD 0.5–1.0 M per campaign.”
Application | Separator Type | Key Specs | Feed State | Market Share | Typical Plant |
API slurry polishing | Parallel Type Liquid Magnetic Separator | 1.2 T, Fe ≤ 5 ppm | Liquid slurry | 30 % | DSM 5 kt/yr antibiotic line |
PTA catalyst recovery | Automatic Drawer Magnetic Separator | 1.2 T, Co recovery > 99 % | Powder | 25 % | BP Zhuhai PTA 1.2 Mt/yr |
Agrochemical pigment | "U" Style Tandem Liquid Trap Magnets | 1.3 T, 150 °C rated | Viscous paste | 20 % | Syngenta azo pigment unit |
Fine-chemical pigments | Drawer Magneic Separator | 0.9 T, 30 bar | Pneumatic convey | 15 % | Clariant 15 kt/yr pigment |
Solvent recycling | Drum Magnetic Separator | 2 mm non-ferrous cut | Liquid stream | 10 % | SABIC 50 kt/yr MEK loop |
● Ultra-fine catalyst loss → Switch to matrix HGMS with 200 µm wires; Co loss cut from 1.2 % → 0.3 %.
● Aggressive solvents → Hastelloy C-276 housings + PTFE linings, corrosion rate < 0.025 mm/yr.
● Explosive dust (ATEX) → Ex d IIB T4 motors, intrinsically safe sensors; zero incidents since 2020.
● Chemical: REACH 2023, FDA 21 CFR 211 for pharma
● Safety: ATEX 2014/34/EU, IECEx, PED 2014/68/EU
● Quality: ISO 9001, ISO 14001, OHSAS 18001
● Capacity: 1 500 units/year across three global plants; standard rotors on shelf ≤ 2 weeks.
● Lead time: Standard 6–8 weeks, engineered specials 10–12 weeks.
● QA: 100 % gaussmeter mapping, hydrostatic test 1.5× MAWP, FAT/SAT protocols.
● Added value: CFD-thermal modeling, on-site magnetic audit, annual matrix-replacement contracts.
A European fine-chemical producer upgraded its azo pigment line with HGMS-1500:
● Fe contamination dropped from 25 ppm → 3 ppm.
● Product rejection rate fell by 40 %, saving € 1.1 M/year.
● Campaign life extended from 45 → 60 days, cutting downtime 25 %.
● System passed FDA audit in 2023 and is now qualified for pharmaceutical-grade pigment supply.
