We invariably cool the compressor discharge prior to dehydration. Unfortunately, natural gas will be reheated—sometimes by 10°F — in a typical gas field dehydration contactor.…
There are three factors which increase an air cooler’s inlet temperature: • The compressor valves are faulty. • The compression ratio has increased. • High…
Whenever finned—tubed cooling bundles are arranged in parallel, as shown in figure 5-2, a potential exists for poor cooling due to gas maldistribution. A low…
Air flow from a fan will vary considerably with the blade pitch. The pitch is adjustable. To save engine horsepower, an operator may set the…
Most fans are designed for a maximum fan tip speed of 14,000 feet per minute. To calculate the tip speed of the fan, do not…
If the air flow existing from the tube bundle is hotter than the effluent gas, the chances are there is insufficient air flow to properly…
Underground gas transmission pipelines are externally wrapped in a protective plastic type coating. Gas temperatures in excess of 130°F to 140″F can cause embrittlement and…
1. Check interstage line temperatures to determine which valves have been removed from a cylinder. 2. Remove disabled valves, cages, and valves in ends taken…
Attempting to utilize a single compressor to service both the casing and tubing flows on a dual completion well can present some real problems. On…
field compressor to trip-off prematurely. In this case, the field operators were reporting that they could not operate a compressor suction below 70 PSIG. Their…
