Oman Cement line upgrade

Published 12 February 2013

Oman Cement Company (OCC) has a significant and influential place in the sultanate. The company operates a cement plant close to the capital Muscat, with two 2000tpd dry-process clinker lines and one 4500tpd dry-process kiln. It has recently embarked upon a project to improve environmental performance of Line No 1 and enlisted the services of SEPEC of China, with results proving to exceed expectations.

OCC signed the contract for Line No 1 emission control equipment with

Sino Environment Engineering Development Co Ltd of China (SEPEC) in 2011


Kiln Line No 1 at OCC’s cement works was built by ThyssenKrupp Polysius in 1983. The original electrostatic precipitator (ESP) for controlling gas emissions from the preheater and clinker cooler was designed by Lurgi of Germany.

After many years of use, OCC found that the ESP was not achieving its nominal capacity for dust collection and emissions were reaching at least 200mg/Nm3 – well above regulatory standards. Therefore, the cement producer decided to improve the environmental performance of Line No 1 and in 2011 signed a contract with Sino Environment Engineering Development Co (SEPEC) of China for emission control equipment.
