CompHP is a compressor horsepower calculator. It replaces the cardboard circular slide rule that just about every natural gas engineer has received from a compressor vendor at some point; however, in addition to a horsepower calculation, with CompHP you can also:

• see the effect of suction temperature on compressor horsepower
• see how gravity and diluent content affect compressor capacity
• calculate intercooler and aftercooler heat duties
• determine the effect of valve pressure drop on compressor capacity at low suction pressures.

For a limited time, CompHP is included at no charge with all PDrop orders.
