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. 

Straight-Through Flow Design Ideal for TRS Mist Samples

Flammable non-condensible gases (NCG’s), usually referred to as Total Reduced Sulfur compounds (TRS) or Dilute Vent Gases, are byproducts of the wood pulping process. These gases, mostly sulfurous, are extremely malodorous and flammable. 

Health and pollution regulations prohibit the release of these gases into the atmosphere. They are usually eliminated by passing them through an incinerator or by using them as fuel in the burner of a boiler or kiln.

Problems in Pulp & Paper Mills

Last week we talked about the pulp & paper mill process. In the past, continuous sampling and gas monitoring was a problem for this applicaion for three key reasons:

An Analyzer Immune to Poisons and Corrosives in Wastewater Treatment

We've been talking about the 3 Key Challenges of Monitoring in Wastewater Treatment. Last week we addressed the first one, this week let's focus on the second:

Manufacturing Day 2017

Happy MFG DAY 2017!!

Manufacturing Day is an annual celebration of modern manufacturing during which manufacturers invite their communities — including students, educators, businesspeople, media, and politicians — to their facilities in a collective effort to educate visitors about manufacturing career opportunities and improve public perceptions of manufacturing. Started in 2012, MFG DAY has seen participation grow dramatically over the years. 

THE MANUFACTURING DAY MISSION

Rugged Durable Construction in Wastewater Treatment

Last week we talked about the 3 Key Challenges of Monitoring in Wastewater Treatment. Let's address the first one:

  1. High moisture and humidity can promote corrosion, contamination and clogging that can lead to unreliable readings.

How can the right monitoring system combat these issues? Heat & a simple flow system.

Key Challenges of Monitoring in Wastewater Treatment

Publicly owned treatment works (POTWs) collect wastewater from municipal, commercial and industrial facilities, transport it through a series of contributor pipes, known as a collection system, and deliver it to the treatment plant.

Regulations prohibit these facilities from discharging flammable or explosive wastes from their processes into the liquid collection system. In addition to fire and explosion hazards, these wastes can affect the efficient and effective operation of the treatment facility.
