When industrial customers choose columnar activated carbon (GAC) to treat waste gas, they are most concerned about the three pain points of cost control, compliance, and convenient operation and maintenance. This article uses real data and cases to directly address the core needs!
1. The five major issues that industrial customers are most concerned about
| Pain points | Pillar activated carbon solution | Parameter support |
| High operating cost | Recycled 5-8 times, the cost of treating one ton of waste gas is ￥0.3-0.8 | Compared with disposable carbon, it saves 60% |
| The equipment occupies a large area | High stacking density (0.5g/cm³), the tank volume is reduced by 40% | Only Φ3m×6m tank is needed to treat 50,000 m³/h air volume |
| Emissions do not meet the standards | Carbon tetrachloride adsorption rate＞65%, non-methane total hydrocarbons＜50mg/m³ | Meet the national standard GB 37822-2019 |
| Frequent replacement | Compressive strength＞12N/particle, backwash loss＜3%/year | Lifespan 24-36 months (granular carbon only 12 months) |
| Hazardous waste disposal is difficult | Equipped with a thermal regeneration system, waste carbon reduction by 90% | Iodine value retention rate after regeneration ≥ 85% |

II. Benchmark case – data speaks Case 1: VOCs treatment in automobile paint shop (a German brand) Working conditions: Air volume 80,000m³/h, xylene peak concentration 800mg/m³ Emission requirement <30mg/m³ (German TA-Luft standard) Solutions we provide: Φ4mm coal-based columnar carbon (CTC≥70%) Dual tank adsorption (6 seconds contact time) + Steam regeneration (110℃) Results: Emission concentration is stable <20mg/m³ Annual carbon consumption from 120 tons to 25 tons (regeneration 5 times), cost reduction of ￥3.8 million Case 2: Solvent recovery in pharmaceutical plants (a pharmaceutical company in East China) Pain points: Acetone/ethanol mixed waste gas, recovery purity requirement >95% Original activated carbon is seriously pulverized, and it is shut down for replacement every month We provide an upgrade plan: High-strength coconut shell columnar carbon (compression resistance >15N/particle) Nitrogen protection desorption (anti-oxidation loss) Benefits: Solvent recovery rate 92%, purity 99.5% Replacement cycle from 1 month to 18 months, annual increase of ￥20 million
