How to import Aspen Properties / Aspen Plus into Hysys

Fluid package and binary interaction parameter can be imported into Aspen Hysys.

Steps:

1.create new file

2. go to fluid package

3. click import

4. select Aspen Properties file


note:

this method will only import components, property methods, user -entered parameters, chemistry .
No stream , block , flowsheet will be imported.

No stream , block , flowsheet, i will post the method on the next blog post.


Benefit on import features:
Hysys users now can model polymer, electrolytes and pharmaceuticals process.

Type of Cleaning Pigs in Oil and Gas

Cleaning Pigs

Poly Pig

The flexible polyurethane pig is ideal for applications when the pipeline condition is not well known, and the primary requirement is to ensure the pig does not block the pipeline.

Pin Wheel Pig

The pin wheel pig is designed to aggressively remove debris such as scale and hard wax from the walls of the pipeline. Hard steel pins with tungsten carbide heads, attached to polyurethane disks on the pig, burst and scrape debris from the pipewall. The aggressiveness of the tool can be adjusted by removing some of the pins, lengthening or shortening the pins and using more or less resilient polyurethane for the pin wheel. The pin wheel pig is usually towed through the line by a heavy-duty magnetic cleaning pig using a specially-designed universal coupling.

Pressure Bypass Pig

This is a simple but effective solution to a critical situation that can occur when pigging liquid lines. A scraper pig loosens debris and bulldozes it along the line. On occasion, the amount of debris becomes so great that the pig can no longer move it, resulting in a stuck pig and a blocked pipeline. Our solution is a cleaning pig that responds to the formation of a slug of debris by bypassing liquid product through its body. As debris builds up in front of the pig, the differential pressure across it builds up as the pig finds it more difficult to move. When the differential pressure reaches a critical value, a relief valve in the pig body opens and allows product to jet through the pig, flushing away the debris in front of the pig and enabling it to move. The bypass pig is often used to push a stuck pig out of the pipeline.

Inhibitor Spray Pig

The inhibitor spray pig applies a corrosion inhibitor to selected problem areas in a high-pressure pipeline, avoiding the cost of bulk inhibitor for the whole pipeline. The corrosion inhibitor is stored in the front and center modules, while high-pressure nitrogen is held in the rear. Nitrogen is required to displace the inhibitor as the pig travels through the pipe. A spray array is attached to the back end of the pig to distribute the inhibitor.

Magnetic Cleaning Pig

This pre-inspection pig removes ferrous metallic debris, such as welding rods, from a pipeline. It uses strong permanent magnets to collect and hold the debris.

Cup Pig

These pigs are designed for use in long runs in which wear may be a special concern. They are specified for commissioning of pipelines as an alternative to bi-directional pigs, and for separation of different media.

Brush Pig

The brush pig is a bi-directional cleaning tool that cleans without scraping the interior wall of the pipeline. It uses both metallic and non-metallic brushes, and is as vigorous and versatile as other bi-directional pigs. Brush pigs are ideal for use in aviation fuel pipelines.

Circumferential Brush Pig

The circumferential brush pig is similar to a regular brush pig, but its cleaning brushes are non-segmented and therefore cover the full 360 degrees of pipewall.

Dual Diameter Pig

This pig seals tightly to the internal pipewall, and can be custom produced for any diameter differentials.

Bi-Directional Pig

This pre-inspection pig removes ferrous metallic debris, such as welding rods, from a pipeline. It uses strong permanent magnets to collect and hold the debris.
