Moisture recovery from gas-fired boiler exhaust using

2019-9-10 · Many studies on the moisture recovery of flue gas by the membrane method use a single ceramic membrane tube to recover the simulated flue gas. In this paper, a membrane module array containing 46 ceramic membrane tubes was constructed to recover moisture and heat in real flue gas produced by a gas-fired boiler.

Removal of Chloride in the Kraft Chemical Recovery Cycle

2020-5-29 · High levels of chloride in the kraft recovery cycle of pulp mills can cause serious problems, particularly in recovery boiler operation. The treatment of ash collected from the electrostatic precipitator (ESP) for chloride removal was investigated experimentally using the ion-exchange process based on an amphoteric resin (BIORAD AG 11 A8).
