Turn-key supply of an ammonium sulfate plant at a coke
plant in France
Design of four Claus plants for coke plants in Korea
The Claus process is an important component of
low-emission coke production.
Turn-key supply of a cooling and chilled water system
at a coke plant in Germany
Low temperatures guarantee a better cleaning efficiency
of the coke oven gas in the scrubbing plants. This means
an improvement of the emission value and the quality of
the products especially in the warmer summer months.
To match the increased requirement of cooling capacity
an existing cooling tower was replaced by a new one
and additionally a new chilled water system was erected.
clean the ammonia loaded coke oven gas a
half-direct process was used where the coke oven gas
passes through so called spray saturators
nThree of the existing saturators were replaced by two
new saturators including the downstream peripheral
nThe volume of coke oven gas treated amounts to
45.000 Nm3/h per saturator
nThe ammonia loading could be reduced from
9 g to < 30 mg per Nm3 coke oven gas
n Pressure drop in the saturator is recorded with less
than 130 mm WC (13 mbar)
Contract included:
nBasic Engineering for 4 Claus plants at two different
sites in Korea
nDelivery of key components for the process
nSupport of erection supervision and commissioning
The throughput of each plant is 6.000 m3 vapors per hour
consisting mainly of H2S, NH3, HCN, H2O
Completion: September 2007
Project duration: 26 months
Completion: May 2008
Project duration: 17 months
nThe new cooling tower was designed for an amount
of 2.900 m3/h cooling water. This amount is cooled
down from 43OC to a temperature of 26OC
nThe new chilled water system consists of two
compression refrigerating plants. Per unit 462 m3/h
chiller water is chilled down from 24OC to a
temperature of 17OC
This project was realized in a consortium with Axima
Refrigeration GmbH, Lindau, Germany.
Completion: October 2007
Project duration: 11 months
