Title: Bertel K Hakulin: Innovator in Chemical Recovery Processes

Introduction

Bertel K Hakulin is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of chemical recovery processes, particularly in the pulp and paper industry. With a total of four patents to his name, Hakulin's work focuses on innovative methods for treating black liquor and gasifying solid carbonaceous materials.

Latest Patents

One of Hakulin's latest patents is a method for treating black liquor. This invention involves a method and apparatus for recovering black liquor chemicals and heat in a sulphate pulp process. The black liquor is concentrated in an evaporation plant, which includes a pressure heating reactor. After this process, the black liquor is gasified or combusted in a reactor to produce hot gases. The hot gases formed in the reactor are then introduced into a gas turbine power plant. The exhaust gases from the gas turbine are directed into a waste heat boiler, where steam is generated for a steam turbine power plant. Additionally, secondary steam is led from the pressure heating reactor as injection steam into the gas turbine to control the inlet temperature.

Another significant patent by Hakulin is for an apparatus designed for gasifying or combusting solid carbonaceous materials in a circulating fluidized bed reactor. This invention separates particles from the product gas in at least two stages. In the first stage, mainly coarser, circulating particles are separated and returned to the reactor. In the second stage, fine carbonaceous particulates are separated from the gas and agglomerated at a raised temperature. Coarser particles are then returned to the reactor through a return duct, ensuring that adhesion of agglomerating particles to the walls of the duct is prevented.
