Difference Process shutdown (PSD) and Emergency Shutdown (ESD)

ESDV ACTUATOR

PSDV ACTUATOR

PSD is defined as the automatic isolation and the activation of all part of a process. During a PSD the process remain pressurized, Basically PSD consist of field mounted sensors. Valves and trip relays, a system logic unit for processing of incoming signals, alarm and MHI units. The system is able to process all input signals and activating output in accordance with the applicable cause and effect matrix chart

Typical action from PSD systems are:

1.       Shutdown the whole process

2.       Shutdown part of the process

3.       Depressurize/Blow down parts of the process

The emergency shutdown (ESD) is shutdown to minimize the consequences during emergency. ESD can be automatically initiated by load shedding functions or manually by the operator through push button on the panel. ESD will shutdown an isolate all designated process related equipment, including inlet and outlet ESD valves. Depends on each project some plant will allow the power generation, utilities and fuel gas system keep running during this condition.

ITEMS SAFETY INSPECTION CHECK FOR GAS TESTING

1. Are personnel trained in the use of gas detector equipment?
2.  Is there a master list on site of the certified authorized gas testers?
3. Are the portable gas detectors kept in a secure location when not in use?
4. Are the portable gas detectors uniquely identified and is the latest calibration date displayed?
5. Is maintenance work on gas detector carried out only by qualified personnel?
6.  Are the portable gas detectors tested prior to issue as per the pre-issue checklist?
7. Has a gas test been completed before any Hot Work commences in classified area?

ITEMS SAFETY INSPECTION CHECK FOR IONIZING RADIATION

1.  Are radioactive isotopes used on site? If so are personnel aware of the dangers?
2.  Are all the required personnel carrying dosimeters?
3.  Is the storage area regularly surveyed and the results below 7.5 uSv /hr.
4.  Is the labeling of the storage area sufficient?
5.  Is the labeling of the source containers clear?
6.  Are sufficient barriers/warnings/flashing lights in place prior to exposing a source?

ITEMS SAFETY INSPECTION CHECK FOR WORKSHOP

1. Is the workshop outside a hazardous area?
2. Does the electrical installations look satisfactory?
3. Are there any temporary electrical installations?
4. Are there 3 means of cutting off the electrical supply to any machine?
5. Is the local stop/emergency button well labelled & in red?
6. Is any "dead man" handle being bypassed?
7. Are all moving parts adequately guarded?

CORROSION INHIBITOR SKID WELLHEAD PLATFORM

A general term for injection processes that use special chemical solutions to improve oil recovery, remove formation damage, clean blocked perforations or formation layers, reduce or inhibit corrosion, upgrade crude oil, or address crude oil flow-assurance issues. Injection can be administered continuously, in batches, in injection wells, or at times in production wells.

AutoCAD Tool Palettes – Cable Tray, Tubing Tray and fitting included attribute for 3d models

STRAIGHT CABLE TRAY USE AUTO LISP

SAMPLE ASSEMBLING WITH FITTING TRAYS

Adding and editing components becomes easier in AutoCAD with tool palettes. The tool palettes contain blocks. With the parameter action Polar Stretch, you can just type the length you desire and AutoCAD will stretch the tray to that length. Furthermore, you can rotate the block before you place it. In my opinion the tool palettes are user friendly. Even a novice can use them. Moreover you can insert blocks into your drawing with drag and drop. It is easy to access from tool palettes.

Open and close the tool palette by pressing CTRL+3. You can auto-hide the tool palette in the vertical blue area of the tool palette, simply click on the symbol <>I. By doing that, you leave more space in the drawing area.

Exploration and Drilling

When 3D seismic has been completed, it is time to drill the well. Normally dedicated drilling rigs either on mobile onshore units or offshore floating rigs are used. Larger production platforms may also have their own production drilling equipment.

The main components of the drilling rig are the Derrick, Floor, Drawworks, Drive and Mud Handling. The control and power can be hydraulic or electric.

Earlier pictures of Drillers and Roughnecks working with rotary tables (bottom drives) are now replaced with top drive and semi automated pipe handling on larger installations. The hydraulic or electric top drive hangs from the derrick crown and gives pressure and rotational torque to the drill string. The whole assembly is controlled by the drawworks.

The Drill String is assembled from pipe segments about 30 meters (100 feet) long normally with conical inside threads at one end and outside at the other. As each 30 meter segment is drilled, the drive is disconnected and a new pipe segment inserted in the string. A cone bit is used to dig into the rock. Different cones are used for different types of rock and at different stages of the well. The picture shows roller

cones with inserts (on the left); other bits are PDC (polycrystalline diamond compact, on the right) and Diamond Impregnated.

Crude oil and Natural gas

1. Crude Oil

Crude Oil is a complex mixture consisting of up to 200 or more different organic compounds, mostly hydrocarbons. Different crude contain different combinations and concentrations of these various compounds. The API (American petroleum institute) gravity of a particular crude is merely a measure of its specific gravity, or density.

The Oil and Gas Process

The oil and gas process is the process equipment that takes the product from the wellhead manifolds and delivers stabilized marketable products, in the form of Crude Oil, Condensate or Gas. Components of the process also exist to test products and clean waste products such as produced water.
