Case Studies
Bubble spargers enhance process efficiency by increasing mass transfer and mixing intensity, resulting in reduced reaction times, lower consumption of reaction gases, and decreased load on scrubbing systems, offering environmentally friendly solutions. Diva Envitec saves customers thousands of dollars at minimal cost. A chemical and fine chemicals manufacturer needed to perform chlorination in one reaction. Facing high product demand, they planned to install three new 5KL glass reactors, costing USD 450,000 for the expansion.
Advanced oxidation treatment using catalytic hydro-oxidation removes refractory and recalcitrant COD. A multi-purpose API manufacturing plant in Telangana generates 150 KLD of wastewater. The process water and wash water flow to a neutralization tank, then to an aeration system, and finally to an MBBR. COD fluctuations due to the product mix ranged from 5000 to 45000 mg/l, destabilizing the MBBR. Consequently, the high-COD water sent to the CETP resulted in massive penalties for the company.
Surface filtration on candles ensures excellent cake release, maximizing recovery of precious metal catalyst from hydrogenation reactions. The company, a petrochemical giant and one of the largest manufacturers of cinnamic alcohol, an essential ingredient in fine and aromatic chemical production.
