Develop an adsorption system to reduce carcinogen agent, call formaldehyde, is the primary objective of this study. In such way, a proposal to adsorpt the formaldehyde expelled through the gasses venting system in reactors aimed at manufacturing phenolic resin, which is involved chemical reactions of the phenol and formaldehyde, is reported. The task was realized, starting formaldehyde pollution identification was realized using math models, then was designed one adsorption formaldehyde system based on a »Dynamic Water Bubble» built with a set of nozzles. That bubble must insert into the reactor venting line capturing such gas without resistance to the flow. Also, this study follows the ruling issued by the National Cancer Institute (NCI) and the International Agency for Research on Cancer (IARC), whose have reported the formaldehyde as a human carcinogen agent. In this sense, the agencies about the environment have recommended working under of the maximum levels suggested by the World Health Organization (WHO) to avoid cancer risks. However, safe industrial manufacture requires use venting relief system in the reflux line, to avoid runaway reactions ending as a disaster to the reactor. Nevertheless, when there is steam in such line (mix of formaldehyde, phenol, and water), it is expelled to free air introducing pollution. This compound that would fall around the reactor would turn the place into a toxic environment with levels higher than WHO suggested, affecting labor biosecurity. Consequently, the present system turns into a useful tool to reduce this carcinogen agent.
