During the warm-up process, hydrate inhibitor must be injected until the flowline temperatures exceed the hydrate dissociation temperature at every location for a given pressure. Figure 17.5 shows the effects of insulation material to the warm-up time. Hot oiling has two beneficial effects; first, it reduces or eliminates the time required to reach the hydrate dissociation temperature in the ...

When the minimum flow rate is defined as the terrain slugging boundary, a region without severe slugging should be determined as a function of the water cut and including gas lift. In cases where the predicted slugging causes liquid or gas handling problems, the effect of additional choking upstream of the separator should be determined.

The momentum of the incoming slug would be dissipated at the inlet header of the slugcatcher. The function of the pipes was to hold the slug until it could be dealt with. For the ratepayers it was contended that this piece of equipment was essentially an emergency or safety device. It was not known as a vessel. It did not function as a separator.

Slugcatcher - OilfieldWiki A Slug Catcher is an unit with sufficient buffer volume to store the largest slugs expected from the upstream system (i.e. pipeline). The Slug Catcher is located between the outlet of the pipeline and the processing equipment. The buffered liquids can be drained to the processing units at a much slower rate to

Onshore Slugcatcher ( - Kerteh

Slugcatcher is the name of a unit in the gas refinery or petroleum industry in which slugs at the outlet of pipelines are collected or caught. A slug is a large quantity of gas or liquid that exits the pipeline. Slugs. Pipelines that transport both gas and liquids together, known as two-phase flow, can operate in a flow regime known as slugging flow or slug flow.
