Diseño y construcción de un dispositivo piloto con adsorbente a base de carbón activado para retención de compuestos orgánicos volátiles Benceno, Tolueno Etilbenceno y Xileno (BTEX) en aire ambiente para el Complejo Industrial Shushufindi.

Abstract

It was made the design and the construction of an absorption device of volatile organic compounds within the environment for the Industrial Complex Shushufindi based on activated coal, the volatile organic composes to be analyzed will be: Benzene, Toluene, Ethil-benzene, and Xylene (BTEX) since they represent the 95% of the volatile organic composes that are produced inside this Oil Industry. The design and construction of the device was based on Engineering calculus and experimental tests in the laboratory of Safety and Environmental Health (LABSSA EP- PETROECUADOR). For its construction stainless Steel was selected for the framework, glass for the filters and valves, due to its characteristics and properties, mainly its inertia facing the compounds to be analyzed. This device is named active sampler since it consists on a sucking pump, which will help to the air intake in a determined volume, a thermo-hydrometer incorporated to the measurement of temperature, moisture and atmospheric pressure, a timer to control the sampling time and as a fundamental source a glass filter in base don activated coal , which consists on a section of 150 mg of the same , retained by two layers of 3 mm of polyurethane per each side care the pump, all of this assembled to semi-hard silicone hoses for transporting the air toward the pipes. To determine the efficiency of the activated coal, test were made in different lapses of time, by analyzing the pure absorbent as a target; to determine its saturation time and the adequate quantity that has been located inside the filter.
