Ammonia Removal utalizing an Ammonia Scrubber

Part 5 of Abating Hazardous Air Pollutants: Ammonia

What is Ammonia?

Ammonia is a compound of nitrogen and hydrogen. A colorless gas with the formula NH3, ammonia has a pungent smell. Ammonia boils at 33.34 degrees and must be stored under pressure or at a low temperature. Industrial ammonia is sold as either an ammonia liquor or as a pressurized and/or refrigerated anhydrous liquid ammonia transported in Ammonia Scrubbertanks cars or cylinders. In 2014 the global production of ammonia was 176 million tonnes. China is the top worldwide producer with nearly one-third of total production, followed by India, Russia and the United States.

Ammonia molecules have a trigonal pyramidal shape. The molecules shape allows for a dipole moment and makes it polar. This polarity allows the ability to form hydrogen bonds and makes ammonia highly miscible with water. The central nitrogen atom has five outer electrons with additional electron from each hydrogen atom. This makes a total of eight electrons or four electron pairs that are arranged tetrahedrally. Of these electron pairs three of them are used as bonded pairs leaving one sole pair of electrons. This long pair repels more strongly than bond pairs. [Read more…]

Corporate Social Responsibility and Pollution Control

corporate social responsibility and pollution controlCorporate social responsibility (CSR) became popular during the 1980’s and has continued to remain a pillar of corporate structure. Gulf Coast Environmental Systems (GCES) serves as an integral part of many organizations with pollution control as a component of their CSR policy. In this article we will review how to develop a CSR, the advantages and disadvantages of publishing a CSR policy and how to effectively communicate your organizations CSR to improve community relations and public perceptions.

Advantages of Ceramic Fiber Modules aka Ceramic Media

A Comparison of Ceramic Fiber Modules and Fire Clay Castable

Oxidizers treat VOCs, HAPs, and other air contaminants based on proven technology and history.  Engineering these systems to the next level allows them to process vapor laden streams with much greater efficiency and lower equipment operating costs.  One of the ways to improve on the costs of operating these GCES systems is by properly insulating the combustion chambers with the most effective and efficient insulation materials.

Ceramic Fiber Modules
Detail of Structured Media

The combustion chamber serves two purposes within the system. Purpose #1 is to input the required heat energy to bring the process and combustion air up to the required operating temperature with the burner firing into the chamber. Purpose #2 is to retain the process stream at the operating temperature for the required time in order to achieve the desired destruction efficiency – this is typically called the residence time. There must be a layer of insulation to account for heat loss during the combustion process.  The proven material of insulation is the ceramic fiber module.

Dry Scrubber Media Disposal

Revenue Development in Dry Scrubber Media Replacement

When a client came to GCES with a zero waste initiative we had to find a solution for their spent dry scrubber media. We provided them a solution that not only met their zero waste initiative but also allowed opportunity for financial recovery of media replacement costs.

Dry scrubber media, also known as iron sponge sulfide, is composed of iron oxide, elemental sulfur, wood fiber, water, soda ash and limestone.

There are many options for the disposal of spent iron sponge with the most common being simply by spreading the spent media onto an area of land and burying it with a light earth cover. In urban areas the material is generally accepted with EPA approval at a sanitary landfill. In recent years revenue streams and partnerships have been developed between the disposers of the spent media and the agricultural community. In these scenarios agricultural uses for iron sponge include in the farming of tomatoes and coniferous trees such as Christmas trees. [Read more…]

Lead Removal

Part 4 of Abating Hazardous Air Pollutants: Lead

What is Lead?

Back in middle school most of us probably learned a little about lead. It is in the grey area on the periodic table, is a metal, has a chemical element in the carbon group and has a symbol of Pb. Lead is a soft metal that easily tarnishes and has a shiny finish. It is a double magic number in the nuclear shell model which makes it sound quit fancy and it’s many uses and users may agree.

Where is lead found?

Lead is very common in stars but here on Earth lead is found in minerals that are above the Earths crust. It’s compound is similar to zinc and cooper and as with those two minerals is usually found in ore. Lead deposits are also common in hydrothermal vein, impregnation, and replacement deposits; volcanogenic sedimentary deposits; and hydrothermal or marine sedimentary deposits. The largest resources of lead are in Australia, China, Ireland, Mexico, Peru, Portugal, Russia as well as the US. [Read more…]
