Aplicação do conceito de Produção Mais Limpa na otimização do processo de produção de Álcool Butílico
ABSTRACT
The object of this treatise is to describe a typical industrial problem occurred
in a butilic alcohol production plant. Historically, production was carried out
to specifications adequate to the needs of the client. A new client came up
with a much higher degree of requirement for specifications of the product.
At first, the company solved the problem by repurifying the product. The
client was entirely satisfied with this solution but production costs increased
not to mention an additional generation of emanations with a high organic
load. The company was already preparing itself for an improvement project
with investments in widening of purifying columns when it started to adopt a
preventive attitude utilizing Cleaner Production concepts. It was found
through documentary research (primary source) and old technical registers
that a test was carried out by the owner of the technology (with a promoter
on a pilot scale). This promoter inhibited the formation of secondary
reactions. Based on these results, the company carried out tests on an
industrial scale, that is to pay, it moved precisely towards a change in the
process, aimed at reducing to a minimum undesirable secondary reactions
in the reactor and as a consequence a reduction of the organic load in
emanations. The work is supported by concepts in Pollution Control,
Pollution Prevention, Clean Production and Cleaner Production. Corrective
approaches and preventive strategies are examined. The main pipe-end and
prevention techniques are also considered. Environmental strategies and
their characteristics are estimated. For a better understanding of the
problem and its solution, state-of-the art production of oxo-alcohols is
discussed with a focus on the process and the reaction that was optimized.
The work shows results obtained in the study of the application of cleaner
production concepts in process optimization. Prevailing traditional
management aspects are shown as well as environmental and economic
advantages through a prevention logic. This study comes to the conclusion
that old production management paradigms no longer have any support in
the face of the prevention logics of cleaner production.
Key words: Industrial Pollution; Cleaner Production; Clean Technologies;
Optimization Process; Butanol Production.
