Project IB USA – CleanPulse Bag Filter under Positive Pressure with Acid Gas Neutralisation

Project IB USA – CleanPulse Bag Filter under Positive Pressure with Acid Gas Neutralisation

Problem

An international client required assistance in building two flue gas treatment plants for a cellulosic ethanol production plant.

This was a pioneering exercise to turn a new technology into a commercial production plant.

Filter Designs are signed up to a non-disclosure agreement so in this case study we focus on our plant supply in brief.

The challenge was to develop a plant which would operate with Syngas which brought several technical challenges.

Filter designs rose to these challenges to create a system which has now been in operation for several years.

Solution

Essentially several standard filter components were extensively modified to suit the process gases and client requirements. This was technically challenging as above, but to add to this were voltage differences, pressure testing standards (ASME) to comply with and UL certifications to obtain for UK sourced equipment.

We supplied the equipment which was fabricated in the UK, packaged by FDL and shipped to site. Following erection by the US client, we visited to commission and train US operatives.

The filters were extensively pressure tested in the fabrication shop before final fitting and shipping.

The control panels were to a specification to allow seamless integration into the clients main DCS.

Both panels with touchscreen HMI and full programming.

A pneumatics control panel keeps everything neat and tidy without the need for solenoids or regulators in the field.

Packaging was at significant cost since shipping to the states could induce corrosion.

Most items were crated and transported to port out of Leicester.

The commissioning trip to Miami was not all work and the Mustang offered suitable transport to the golf course.

55mph limits do not really give much scope to enjoy the potential.

Our recent Projects

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
