Chemrec AB (Chemrec) English: / ˈ k ɛ m r ɛ k / is a Stockholm , Sweden -based company with comprehensive experience of pioneering the development of black liquor gasification (BLG) technology for energy and chemicals recovery at pulp mills.
23-455: The Chemrec process for gasification of black liquor from the chemical pulp industry offers to increase the yield of high-value energy products from 15 to 16% in modern recovery boilers to 22–23% for the BLG electricity concept (BLGCC) or to 55% for the BLG bio fuel concept (BLGMF), with 90+% green-house gas reduction. Low-cost, low-grade and abundant biomass energy then needs to be brought to the mill for
46-446: A 15-bar pressurized pilot plant at StoraEnso, Skoghall, Sweden, which from 1993 operated air-blown with 6 tds/d capacity and after rebuild in 1996 operated until 2000 as oxygen-blown with 10 tds/d capacity. Thereafter a new 30-bar 20 tds/d development plant (DP-1) at Smurfit Kappa, Piteå, Sweden, started-up in 2005 and logged 28,000 hours gasifier operation whereof 12,000 hours with syngas-fed methanol and DME synthesis operation. Within
69-575: A feed-stock swap to replace the gasified black liquor as feed-stock for production of steam and electricity in a biomass boiler, resulting in a total yield from added biomass to bio fuels of 70% for the BLGMF concept. Chemrec's technology originated in the mid-1980s with an invention by Jan-Erik Kignell who was awarded the Royal Swedish Academy of Engineering Sciences' Gold Medal for this feat in 1993. Kignell sold his black liquor gasification patent to
92-452: A substantially higher thermal efficiency than the process it replaces - the Tomlinson recovery boiler . The location within a pulp mill complex provided benefits. First, environmental permitting was generally easier than for a greenfield industrial activity . Secondly, the pulp mill infrastructure for raw material supply, utilities and energy reuse further reduced investment and provided

161-511: Is currently an Intellectual Property (IP) Holding Company offering an EPC/EPCM company the required license to practice the Chemrec BLG Technology. The following Chemrec BLG units are examples from the wide range of possible tailor-made installations: A300 Booster The 300 tons/day atmospheric air-blown unit increases pulp production through improved black liquor recovery capacity and flexibility in chemical recovery. The A300 Booster
184-435: Is installed in parallel with the mill's existing recovery boiler. A significant benefit of this system is that it can be installed while the recovery boiler continues to operate, thus avoiding down time and lost production. OX300 Booster The OX300 atmospheric oxygen-blown Booster not only increases the black liquor recovery capacity but also produces a fuel gas suitable as lime kiln fuel. In this way lime kiln fuel costs and
207-500: Is scale up of the pressurized and oxygen blown BLG version to 550 tds/d for implementation of a commercial demonstration plant. Black liquor is a biomass feedstock with unique properties. First of all, it is available at existing industrial sites in large quantities. Secondly it is a liquid. This makes it possible to easily feed it by pumping into the pressurized gasifier . With biomass in solid or pulverized form this becomes significantly more difficult. The liquid state also makes
230-422: The sulfite process equivalent of black liquor, is equally or even better suited for gasification. Black liquor gasification fulfills two investment-intensive duties with a single process; it provides the pulp mill with needed black liquor recovery capacity at the same time as it produces syngas for biofuels production . In this way the total investment demand decreases. The Chemrec gasification process had

In 2013 the Piteå plant was transferred to Luleå University of Technology (LTU) and continued operation until it was mothballed in 2016, waiting for next project funding to be completed. The Domsjö Biofuel project was during the period 2009-2012 developed by Chemrec in close co-operation with Domsjö Fabriker in Örnsköldsvik, Sweden with
299-552: The Swedish rolling bearing company SKF , which steel division worked on gasification in the late 1980s, but concluded that the technology related to black liquor was too far removed from the company's core business, upon which other inventors Nils Bernhard and Lars Stigsson acquired the patents in 1989 and founded Chemrec (an abbreviation of "chemical recovery") to exploit the technology. In 1990 Kvaerner (Norwegian engineering and construction services company) bought Chemrec and remained

USD 45 M capital contributions by means of rights issues reserved to the following Venture Capital companies: During the period from 1988, Chemrec developed two pilot plants for first-generation atmospheric air-blown BLG gasifiers, first 1988–1989 with 3 tds/d (ton black liquor solids per day) capacity at SKF, Hofors, Sweden, then 1990–1994 with 75 tds/d capacity at AssiDomän, Frövi, Sweden, and followed by scale-up to
368-568: The black liquor easy to atomize into a fine mist that reacts very quickly in the gasifier. Thirdly, the gasification of black liquor char is more rapid than for any other feedstock as the inherently high sodium and potassium content of black liquor acts as a catalyst . These properties makes it possible to apply the high temperature, entrained flow gasification principle to black liquor. This type of gasification process provides many advantages over alternative gasification technologies: For all practical purposes sodium-based sulfite liquor ,
