Is the operating cost of RTO incinerators really that high?

Many companies are evaluating VOCswaste gas treatmentWhen planning, I heard thatRTOThe operating cost of incinerators is very high, so they are discouraged. Is the operating cost of RTO really that high? This needs to be objectively decomposed.

The main operating costs of RTO come from fuel consumption and electricity consumption. When the concentration of exhaust gas is low and the self heating value is not sufficient to maintain self-sustaining combustion, additional natural gas or diesel needs to be supplemented, which is a significant expense. Taking a medium-sized RTO as an example, the daily fuel cost alone may reach thousands of yuan. In addition, the wind turbine power of RTO is relatively high, and the electricity cost cannot be ignored. If the equipment requires frequent start stop or maintenance, the cost of labor and spare parts will further increase. Overall, for low concentration exhaust gases, the operating cost of RTO is indeed relatively high.

But if the concentration of exhaust gas is high enough to achieve self-sustaining combustion or even excess heat recovery, the operating cost of RTO can be significantly reduced, or even ignored. This leads to a key idea: to increase the concentration of exhaust gas through other processes before entering RTO. The condensation membrane separation process can play this role perfectly. This process first liquefies and recovers most of the organic matter in the exhaust gas through condensation. The remaining low concentration exhaust gas is separated by a membrane, and the organic matter is enriched on the permeate side, forming a high concentration low air flow. This high concentration airflow enters the RTO and is fully capable of self-sustaining combustion, requiring almost no additional fuel. At the same time, due to the significant reduction in the total air volume entering RTO, the energy consumption of the fan also decreases accordingly. LuoyangWohong PetrochemicalThe condensation membrane method system of Equipment Co., Ltd. can seamlessly integrate with existing RTOs, reducing fuel consumption by 50% to 70% through front-end concentration.

So, whether the operating cost of RTO is high or not depends on the concentration of exhaust gas and the front-end pretreatment process. After being combined with the condensation film method, RTO may actually become a low-cost destruction terminal.
