Development of a F22 Compatible Scale Inhibitor
CONFERENCE 2022, 2022Abstract F22, a low alloy steel, has become widely used in oil field production systems. However, current scale inhibitor technologies on the market often cause severe corrosion on F22, particularly at high temperature conditions. Therefore, F22 compatible scale inhibitors are in demand in the oil and gas industry. A F22 compatible scale

Development of an F22 Metal Compatible Scale Inhibitor for Subsea Application
CONFERENCE 2023, 2023Abstract F22 carbon steel has been widely used in subsea field development due to enhanced mechanical properties. However, commonly used scale inhibitors have been shown to be very corrosive against F22, and therefore cannot be injected continuously subsea to control mineral scales. In this paper, inhibition performances of several scale

On a Generalization of Kummer’s Second-Type F11 and F22
2021The aim of this paper is to establish a general form of Kummer’s second-type summation theory. By defining a new form for the divided of the Pochhammer symbol d+in/dn, we can develop a general form of Kummer’s second-type summation theorem as e−x/2F22a,i+d; xb+l,d; in the form of a sum of e−x/2F11a; xb+i; for i,l=0,1,2,…, Then, some properties ...

A Construction for the Smallest Fischer Group F22
1973Publisher Summary The Fischer groups F 22 , F 23 , F 24 are closely related to the corresponding Mathieu groups, and it is natural to attempt constructions in terms of these. This chapter presents that certain difficulties with F 23 and F 24 do not arise for the smallest group F 22 .
