Case Study|Megaunity Partners with COSCO Shipping Group to Build a Green Paint Shop

VOCs in the paint shop are mainly generated by the organic solvents in paintings, with the primary pollutants such as benzene, esters, ketones, alcohols, etc. In response to the national environmental protection policy, Qidong COSCO Marine Engineering Co., Ltd., an industrial player with a high sense of social responsibility, is to install the additional pre-treatment devices + VOCs treatment equipment in its paint shop. As the winner of the public bidding open for this project, Megaunity designed two sets of VOCs treatment systems for Qidong, ensuring that its centralized emissions meet the environmental protection requirements and helping Qidong achieve green construction goals. 

Characteristics of the Project

(1) The project relates primarily to oil-based paints.
(2) The design takes full account of the inconsistency of VOCs’ concentrations in the emission during different operations in the shop.
(3) Tailored design for pre-treating heavy paint mist.
(4) The ventilation system capable of being freely switched while maintaining air pressure balance to meet the treatment demand occurred during the operation on an irregular basis.
Treatment Process 
Front-end pre-treatment upgrade + zeolite rotor (KPR) + RTO
Designed air volume: 200000Nm³/h (Phase I), 30000Nm³/h (Phase II).
Designed concentration: 800-1000mg/Nm3, suitable for the scenario with short time concentration ≥ 1000 mg/Nm³
