Dear All,
As i compared new Rev. of API 521 (2007) with previous one,i saw huge difference in one case for comparing the smokeless capacity of air and steam as below:
-In section of 4.4.3.1.3 of previous Ver. (1997) we see:.....required is approximately 20 percent greater than.....
-In section of 6.4.3.2.4 of new Ver. (2007) we see:..... required is approximately 200 percent greater than.....
I am wondering about becoming a value 10 times larger in new Rev.
I would be very appreciated to hear from you about the reason(s).
Regards
