Rendering Pollution Control: Vapor-Tolerant and Aqueous RTOs Comparison

Vapor-rich and wastewater waste streams, such as those from the rendering process, pose challenges for traditional treatment systems. Gulf Coast Environmental Systems provides robust, economic solutions to these challenges utilizing thermal oxidizers which apply the combination of heat and time to combust pollutants into harmless CO2 and water.

Some of the harshest pollution control applications are in the rendering field of the food processing industry. The waste stream can contain odors, ammonia, fats, grease, water and other vapors, and even particulate matter, all in a wide ranging mix. GCES’ custom designs systems to handle these difficult processes based on each facilities waste output and goals. Included in our solution is the Aqueous RTO wastewater destruction system with capabilities that allow for processing of both air and water pollution simultaneously. The process is controlled through metered injection of the water into a pre-heated inlet stream into the oxidizer for complete destruction using the standard oxidation process. The following is a comparison of the Aqueous Regenerative Thermal Oxidizer (RTO) and a Vapor-Tolerant RTO for implementation in the treatment of food rendering waste streams. [Read more…]

Landfill RNG Case Study

CASE STUDY
THERMAL OXIDIZER
LANDFILL – BIOGAS | NOVEMBER 2018

Industry: Landfill/Waste Management
Project Type: Biogas
Project Goal: Building a biogas facility to develop pipeline quality natural gas
Equipment Type: Carbon Adsorber and Thermal Oxidizer

EXECUTIVE SUMMARY:
Gulf Coast Environmental Systems was tasked with finding a pollution control solution that could handle two combined PSA reject gas vent streams.

PROJECT OVERVIEW:
In this case, Pressure Swing Adsorption (PSA) systems are cleaning biogas from a landfill. Potentially dangerous gases like methane (CH4), carbon dioxide (CO2), sulfides, and ammonia, are created by the decomposition and evaporation of organic compounds as well as chemical reactions between waste components. These gases and other hydrocarbons are often considered greenhouse gases and play a huge role in global warming. According to the EPA, in the United States landfills are the third most prevalent source of methane and other greenhouse gases. Another risk when dealing with methane is the flammability of the gas which is incredibly high. When condensed into a small space, methane is considered an explosive, and should be handled with extreme caution. The fact that a minimal amount of oxygen is present in this particular stream of waste gas eliminates risk of the process concentration becoming combustible that could lead to flashback. However, poorly designed or maintained landfills run the risk of higher levels of oxygen entrainment leading to elevated danger and uncontrolled greenhouse gas emissions. [Read more…]

What’s The Deal With Steel?

While the long-term impact of the recent steel tariffs is unknown, we here at GCES recognize that there will be an impact on nearly every company we do business with. With so much confusion, and bias, around this hot topic, we created the below article to help break it down a little.

What is steel?

Steel

Carbon steel, which accounts for 90% of all steel production, is an alloy that occurs when iron is combined with carbon. It also contains small quantities of silicon, phosphorus, sulfur and oxygen. The iron that makes steel is the 4th most abundant element, making up about 5% of the earth’s crust. It is removed from crust in the form of an ore; the iron is then extracted from the ore by a process known as smelting. Smelting, simply put, happens when you apply heat to an ore, to extract the base metal. Once the smelted iron is combined with carbon, steel is formed. Although steel is made of predominantly iron, it contains 0.03% and 1,075% (depending on grade) carbon, which alone, iron does not. This addition of carbon improves the physical chemical properties of the iron, making it a desirable metal. On top of the physical properties that make steel so versatile, and desirable, it is also considered to be infinitely recyclable. This means it can be melted down, and reused, as many times as needed, without limit.

Because of its high strength, and relatively low cost, steel is one of the most sought after building materials in the world. Used to make everything from weapons, infrastructure, and buildings, to home appliances and automobiles, the steel industry is expected to reach $1.01 trillion in revenue by 2025. [Read more…]

Methyl Mercaptan

What is Methyl Mercaptan?

methyl mercaptan

Methyl Mercaptan, also known as Methanethiol, is a volatile organic compound known as an organosulfur, because it contains sulfur. Methyl mercaptan is a member of a series of compounds, in which there can be chains of up to 20 carbon-atoms attached to sulfur. The chemical formula for methanethiol is CH3SH; it is classified as a thiol.  It is colorless, highly flammable, and has a strong rotten-cabbage-like odor. It is a colorless, low-boiling liquid, that is denser than water. When inhaled, Methyl Mercaptan is very toxic, and the dangerous gas is often overlooked when in low concentrations. It can undergo steam reforming to hydrogen-rich gas over cerium oxide-coated rhodium or aluminum oxide catalyst via the solid-gas reaction, under certain operating conditions. This process has potential use in toxic-waste treatment, such as removal of methanethiol present in industrial-waste off-gas. Because it is derived from decaying organic matter, Methyl Mercaptan is a weak acid, and is reactive with dissolved metals, in aqueous solutions. [Read more…]
