PPM Monitoring in Carbon Beds

Regulations require the chemical industry to continuously monitor VOC emissions and report their compliance status. VOC abatement systems are used to bring exhaust emissions in line with those regulations. Carbon adsorption beds are frequently used in chemical production to control VOC’s by capturing and recycling solvents.

Flame Ionization Detectors (FIDs) are used to monitor the carbon bed exhausts for solvent breakthrough and to control the switching of the carbon beds when they have become saturated.

BTU Monitoring in Flare Stacks

Waste products are collected from various processes around the chemical facility and are sent to a flare stack for destruction. EPA code 60.18 states for optimum combustion efficiency of the stack the waste stream must run at a minimum heating value of between 300-450 BTU/ft3.

Continuous monitoring of the waste stream is necessary to:

Chemical Processes in Real Life

For the past couple weeks we've discussed LFL monitoring in chemical processes, the WHY & the HOW. Now let's see WHAT some real life examples look like (hint…they all have a common theme, they NEED an analyzer that can handle the uniquely tough chemical environment!):

Saving Money in a Chemical Facility

Chemical facilities use a variety of hazardous gases and solvents in their production processes. Danger is present when hazardous buildup of flammable vapors in the atmosphere gets rich enough to ignite or explode. The National Fire Protection Association (NFPA) establishes fire safety standards, including standards for safe operation of processes. 

LFL Monitoring in Ovens, Dryers, and Incinerators

Many chemical processes involve coating a product with a flammable solvent or mixture of solvents and then heating them in a dryer, batch oven, reactor or other source. The solvents evaporate off in the heating process and are directed to an incinerator for destruction, leaving behind the finished product.

In addition to the solvents, the atmosphere may also contain moisture, halogenated hydrocarbons, silicones and other unknown substances.

Danger is present when hazardous buildup of flammable vapors in the atmosphere gets rich enough to ignite or explode.

Application Spotlight: Chemical Processes

Chemical facilities use a variety of hazardous gases and solvents in their production processes. Whenever these substances are transported, processed or stored, the potential risks are high for hazardous conditions. These substances must be continuously monitored to protect personnel and facilities from accidental releases or leakage.

A Pulp Mill In Action

For the past few weeks we've shined the spotlight on the pulp & paper application.

Season's Greetings 2017

May the magic and the wonder of the holiday season stay with you throughout the coming year.

May you be blessed with good health, much happiness, and spectacular success!

Have Fun & Be Safe!

Measuring Multiple Solvents in Pulp Mills

Most monitoring systems are only able to measure the percent of flammability of a specific gas or narrow family of gases. In pulping applications, however, it is necessary to measure the overall concentration of all flammable gases and vapors entering the incinerator.

Getting a Fast Response Time in Pulp Mills

Using an analyzer with high sampling speed dramatically improves response time - an important factor in pulp mill applications. 

The environment of the vent pipe that carries the Total Reduced Sulfur compounds (TRS) is dirty and humid. Most gas sensors are quickly impaired by these conditions, leading to unreliable readings.

Because most sensors can only operate at ambient, as opposed to process temperatures, they are positioned far away from incinerators, using a snaking pipe arrangement and pumps to cool samples.
