--- THE -----

Koppers’ Coke Oven
has been proved to be the most successful on the market, as is evidenced by the fact that in
the comparatively short period of nine years orders for over 9,000 Ovens have been placed
with us, of which number over 4,250 are repeat orders. These orders represent a capital
cost of over

£7,500,000.

-- SIMILAR SUCCESS ATTENDS THE INTRODUCTION OF -

KOPPERS’ NEW SYSTEM OF

BYE-PRODUCT RECOVERY.

In the New System the Scrubbing' process is entirely dispensed with, and the Ammonia is
recovered direct from the Gas in the form of Sulphate.

ADVANTAGES OF NEW SYSTEM

Effluent Liquor reduced by 50 per cent, and upwards.
Great Saving in Steam Consumption;

Greater Yield of Sulphate and Benzol.

Consumption of Water is considerably Reduced.
Less Labour Cost.

Plant is Simpler to Operate, and requires less Supervision.

Plants already at work and under construction to deal with the Gases evolved from upwards of

20,000,000

tons of coal per annum.
