Condensed film organic tail gas recovery unit, skid-mounted design and fast installation

The installation of conventional VOCs treatment equipment typically requires on-site construction, pipeline welding, and instrument commissioning, which can take anywhere from several weeks to several months, significantly impacting normal production. Wohong's skid-mounted condensed film recovery unit has changed this situation. The compressor, condenser, membrane module and control system are all integrated on a steel base, and the assembly and debugging are completed before leaving the factory. After the equipment is transported to the site, it can be put into operation only by connecting the power supply and gas circuit. The installation period is calculated in days, and the operation can be completed within two days.

Another advantage of the skid structure is the small footprint. The equipment can be placed in the open air without the need to build a separate equipment plant, which is especially suitable for renovation projects with limited space. If relocation is required in the later period, the whole hoisting can be used, and the equipment can be reused, thus avoiding the asset precipitation of fixed equipment.

The equipment adopts the combined process of "condensation + membrane separation. The exhaust gas is compressed and pressurized first, then enters the condensation unit, and most of the organic matter is changed from gaseous to liquid through graded cooling, and the recovered solvent can be directly reused. The condensed tail gas enters the membrane separation unit, and by using the difference in the permeation rate between organic molecules and air molecules in the membrane material, the organic matter preferentially permeates to form concentrated gas, which is sent back to the front end for circulation treatment; the air is discharged up to standard. The whole system runs in closed circuit, and the recovery rate can reach more than 95%.

The equipment is driven by electricity and does not consume natural gas.activated charcoalConsumable replacement does not generate hazardous waste. Pure physical separation, no open flame, suitable for chemical, pharmaceutical, printing and other explosion-proof places. Equipped with a PLC-based fully automatic control system, it automatically starts and stops based on the generation of exhaust gases, eliminating the need for dedicated personnel on duty.

Wo Hong can match equipment specifications according to the exhaust gas parameters provided by customers, and the air volume ranges from tens to thousands of cubic meters per hour. It is recommended to complete the exhaust gas test before selection, get the concentration, air volume and component data, and then determine the equipment configuration.
