Squeeze-off & gel patch repair methods for polyethylene pipe in natural gas distribution lines

Creator:

Harris, Kevin E.

Abstract:

The natural gas industry has become essential in many areas in the United States. Currently there is over 37.5 million miles of natural gas distribution lines. A large majority of these lines are polyethylene pipes. With such a large percentage of polyethylene lines in use gas companies are continually looking...

Strategies for process flowsheeting

Creator:

Sanz, Carlos C.

Abstract:

Two packages of subroutines were developed to perform material balances on chemical processes using the simultaneous modular approach and the equation-based approach. The performances of these packages were compared for five different processes under at least two conditions: one with no design specifications, and one with two or more design...

Deposition characteristics of magnesium silicate and calcium carbonate in cooling tower water

Creator:

Lee, Sai Heep

Abstract:

Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

Calcium carbonate scaling characteristics of cooling tower water

Creator:

Coates, Kenneth Edwin

Abstract:

Scaling characteristics of calcium carbonate on a heated surface in cooling tower water was investigated. Bulk temperature was maintained constant at 95°F. Flow velocities and surface temperatures ranged from 3 ft/sec to 10.3 ft/sec and from 105°F to 170°F respectively. City water was used as make-up for two different water...
