Study Notes
Continuous Emission Monitoring Systems (CEMS)
- Continuous Emission Monitoring Systems (CEMS) report emissions directly to the EPA.
Online Product Analyzers
- Online product analyzers provide operators with real-time data.
Conductivity
- Conductivity measures a material's ability to conduct electricity.
- High conductivity indicates a need for blowdown.
pH Levels
- Solutions with a pH below 7.0 are acidic.
- Solutions with a pH above 7.0 are alkaline.
Analyzers in Distillation Columns
- BP analyzers are commonly found in distillation columns.
Plant Worker Safety
- Plant workers often wear personal protective equipment (PPE), including gas testing monitors, to identify potential harmful substances.
Gas Testing Requirements
- Gas testing is not always required for entering vessels containing steam or water if the vessel has only minor leaks (small holes in contained steam or water).
Fugitive Emissions Sources
- Fugitive emissions can originate from packing leaks, valve gaskets, and cracks in pipes/lines.
Hydrometer Function
- A hydrometer measures the density or specific gravity of a material. It also measures the viscosity of a material.
Cloudiness Measurement
- An opacity analyzer is used to measure cloudiness (turbidity) in a process stream.
Fifth Process Variable
- Analyzers are sometimes referred to as the 5th process variable.
