Abstract

This paper is concerned with the technical and economic aspects of the soda ash production in the Arabian Gulf. Five different manufacturing methods are outlined. The two main manufacturing methods (the Solvay and Dual processes) are examined in detail. The technical aspects regarding the raw material quantitative and qualitative requirements, the battery limits plant production units and utility requirements are specified in each case. A preliminary economic evaluation of each of these two processing routs concludes that soda ash production by either route is competitive with imported soda ash assuming full marketability of soda ash and its by-products in the Arabian Gulf and neighbouring regions. The Solvay and Dual processes are estimated to produce soda ash at a cost of 132 and 144 $ /ton respectively. These production costs compare favourably against delivered costs of imported soda ash of 177 $/ton.
