Chemical Recovery | Industrial Efficiency Technology

For economic and environmental reasons, chemical recovery processes are used in chemical and semi-chemical pulp mills to reclaim spent cooking chemicals from the pulping process. At kraft and soda pulp mills, spent cooking liquor, referred to as weak black liquor, from the brown stock washers is routed to the chemical recovery area. The chemical recovery process involves concentrating

Black Liquor Recovery Boilers - An Introduction

Black Liquor Recovery Boilers - An Introduction : The sodium sulfate or kraft pulping process was patented in 1884 and accounts for over 80% of all pulp produced in North America. This process would not be economically viable without the black liquor recovery boiler (BLRB). The purpose of the BLRB is to reclaim the spent pulping chemicals

Black liquor gasifiers for the paper and pulp sector

2019-9-24·Pulp mills have used black liquor as an energy source since the 1930s. At pulp mills today, black liquor is burned in so-called Tomlinson recovery boilers to generate steam and recover pulping chemicals for re-use. The steam is expanded through a turbine to make electricity that meets a portion of the process electricity needs.

Kraft process - Wikipedia

2019-9-25·The kraft process (so called because of the superior strength of the resulting paper, from the German word Kraft for 'strength') was invented by Carl F. Dahl in 1879 in Danzig, Prussia, Germany. U.S. Patent 296,935 was issued in 1884, and a pulp mill using this technology started (in Sweden) in 1890. The invention of the recovery boiler by G. H. Tomlinson in the early 1930s was a milestone in
