Simulasi tentang Logical operation

1. LogicLogic

2. Adjust
Gunakan operasi ADJUST untuk menyesuaikan satu variabel
hingga variabel target mencapai nilai yang ditentukan pengguna
atau cocok dengan spesifikasi.

3. contoh
open a new case with Peng Robinson as the Property
Package
and the following components: Methane, Ethane, Propane, i-
Butane, n-Butane, i-Pentane, n-Pentane, n-Hexane, n-
Heptane and n-Octane

4. Install a separator V-100 so that the
Connections page of the the
Design tab
install the ADJUST by
selecting Add
Operation from the
Flowsheet menu,
followed by choosing
the ADJUST option.
The Specifications for
the Connections and
Parameters are given

5. SET
SET digunakan untuk mengatur nilai variabel proses tertentu
(PV dalam manual) sehubungan dengan PV lain. Relasi harus
dalam bentuk Y = mX + b dan variabel proses harus dari tipe
yang sama.
Misalnya, bisa menggunakan SET untuk mengatur satu suhu
aliran material agar selalu 20 derajat lebih panas dari suhu
aliran material lain. SET dapat bekerja dua arah (mis. Jika
target diketahui dan bukan sumbernya, target akan "mengatur"
sumber).

6. contoh
select the Property Package (Peng Robinson), and add the four
components CO, Hydrogen, H2O and Methane. The following
conversion reaction will be modelled:
Add a Conversion Reaction and complete the Stoichiometry tab of
the Conversion Reaction as shown here. On the Basis tab of the
Conversion Reaction view, set the Base Component to be CO,
and the Conversion to 80%.

7. There will be two feed streams to the reactor (Separator), one being
pure CO, and the other pure H2. The feed streams are displayed
below. The Molar Flowrate of CO Feed is known and equal to 100
kgmole/hr.

8. Add a SEPARATOR with the following specifications:
On the Reactions tab of the Separator property view, add the
reaction set which contains the Conversion Reaction
install a SET operation which sets the Molar Flow of H2 Feed
in stoichiometric proportion to CO Feed.

9. RECYCLE
Gunakan operasi ini setiap kali perlu me-recycle stream. Blok logis
menghubungkan dua aliran
Sebelum Anda dapat menginstal RECYCLE, flowsheet harus sudah
selesai. Itu berarti perlu ada nilai untuk aliran yang diasumsikan dan
yang dihitung. Setelah recycle terpasang dan berjalan, simulator
membandingkan dua nilai, menyesuaikan aliran yang diasumsikan,
dan menjalankan flowsheet lagi. simulator mengulangi proses ini
sampai dua aliran cocok dengan toleransi yang ditentukan.

10. contoh
a two-phase feed stream (FEED) is mixed with a recycled stream
(RECYCLE) and fed to separator V-100. The vapour from V-100 is
expanded in expander E-100 and then reflashed in separator V-101. Half
of the liquid from this separator is fed to pump P-100 and then recycled
back and mixed with the fresh feed

11. The conditions and composition of stream FEED are shown here
(using the Peng Robinson Property Package).

13. Specify the stream RECYCLE using the P-100 OUT specs.
