Flammable Gas Monitoring in Single Solvent Chemical Applications

When selecting an analyzer, it’s always a good idea to enlist the advice of a specialist in the field. Do not assume that “one size fits all” or that the analyzer which was correct for a previous job will also be the right choice for another application. The specific details of each application need to be examined closely to prevent disaster, especially in the complex chemical environment.

Monitoring the Area of Chemical Facilities

Hazardous gases or vapor-producing liquids are transported, used and stored in the production plant of chemical facilities. In any of these operations there exists the possibility that the hazardous gases or liquids could accidentally leak or spill into the surrounding area.

PPM Monitoring in Real Life

For the past couple weeks we discussed PPM monitoring in chemical processes; in both Carbon Beds and Oxidizers. This week let's look at a real life solvent recovery application:

PPM Monitoring in Oxidizers

In continuation with last week’s discussion on regulations required in the chemical industry, incineration is another way to bring exhaust emissions in line with regulations.

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 Real Life

For the past couple weeks we discussed BTU monitoring in chemical processes; WHY you should monitor your flare stack & with WHAT technology. This week let's look at HOW you would do just that, in real life applications:

Continuous Measurement for your Flare Stack

As we talked about last week, continuous monitoring of the waste stream is necessary to identify the minimum heating value (which also helps determine if it can be used as a standalone fuel source) and ensure proper combustion efficiency.

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.
