Revision

Detail Response to Reviewers’s Comments

Thank you very much for the correction, suggestion, and recommendation for revision. I have revised the manuscript entitled “An Effect Of Spray Configuration And Adsorbent Material On Performance Of The Spray Scrubber In The Downdraft Gasifier-Engine System” as the Reviewers’s comments and suggestions. The revisions are colored in Blue in the Revised Manuscript. Meanwhile, detail response to the reviewers’s comments and suggestions are as follows:

Reviewer A Comment:

Equation too small and not clear

Response:

I have enlarged all Equations

Comment:

This methodology already been used in your experiment…. Thus it should be in “past tense”

Response:

Thank for the correction. I have rewritten the tense of the Methodology in past tense. The correction is:

Figure 2 shows a photograph and schematic diagram of an experimental setup in the present work. The setup consisted of an air-stage downdraft gasifier, blower, water spray scrubber, suction fan, flare, and measurement devices (K-Type Thermocouples, Data Logger Graphtec GL 240, Rotameter, and Impinging Bottle).

In the present work, the adsorbent flow rate was maintained at 5 lpm. The gasifier was run on the feedstock of rice husk at equivalence ratio of 0.30. Firstly, the scrubber was tested under three different spray configurations, i.e. cross spray, counter spray, and mixed spray using adsorbent of tap water. The schematic diagrams of spray direction relative to the producer gas flow were presented in Fig. 3. The adsorbent sprays perpendicular to producer gas flow in cross spray configuration, parallel but in opposite direction to producer gas flow in counter spray configuration, and combination of cross and counter spray in mixed spray configuration. Secondly, the scrubber was evaluated by changing the water with waste of cooking oil follows by waste of engine lubricant. The selection of water, waste of cooling oil and engine lubricant was based on the availability and accessibility. Those adsorbents can be obtained freely. The selection was also based on the density and specific heat of those adsorbents as shown in Table 1. The density and specific heat of water, cooking oil, and engine lubricant were not very much differ. In this second part, the tests were performed under cross spray configuration with adsorbent flow rate of 5 lpm.

Comment:

Density of water should be 1000 kg/m

³

, author must have put wrong info on the column.

(9)

Response:

I have corrected the label between specific heat and density in Table 1.

Adsorbent Specific heat (kJ/kg.K)

Density (kg/m

³⁾

Water 4.18 1000

Cooking oil 1.67 840

Engine lubricant 2.05 872.5

Comment:

It is not clear on how tar content was measured. Please include.

Response:

I have include the tar content measurement in the revised manuscript. The revision as follows The gravimetric tar (mass of the tar in producer gas) is obtained by condensing the isopropanol collected from the impinging bottle in electric oven at a temperature of 50°C for 2 hours. The isopropanol evaporates but the tar remains. This remaining tar is weighted to obtain its mass.

Once the mass of tar before and after the scrubber are obtained, tar removal effectiveness is calculated using Eq. (3).

Comment:

i = inlet and o = outlet should be indicated somewhere so that reader doe not get confused of what they are,

Response:

I indicated the notation I and o in the second sentences of section 3.1 as follows

The temperature of the producer gas at inlet and outlet are indicated by T

gi

, and T

go

, respectively.

Meanwhile, temperature of water at inlet and outlet are indicated using Twi and Two, accordingly.

Comment:

1= inlet and 2 = outlet??? Figure 5

Response:

1 is inlet for gas and outlet for water, and vice versa. I have added this sentence as

Average inlet and outlet temperatures of the producer gas and the water are given in Fig.5. Label 1 on horizontal axis indicates inlet of the producer gas and outlet of the water and vice versa for label 2 (counter flow).

Comment:

Please elaborate more on LMTD and heat transfer Response:

Additional discussion has been added. The additional discussion is

(10)

Increasing heat transferred causes faster cooling process of the producer gas. This means that the producer gas temperature reaches condensation temperature of tar faster, thus increasing effectiveness of the scrubbing process.

Comment:

Incomplete sentence in Discussion of Figure 7

Response:

I rewrote the sentence. It becomes

The most effective tar removal is observed for CsS configuration. The effectiveness of the CsS configuration is 0.43.

Comment:

LMTD is already been defined… delete this sentence.

Response:

Yes it is. I have deleted it

Comment:

April 2016 and 2014… which one is the correct one?

Response:

The correct one is 2014

Comment:

Other Reference journal title are in full, why this one (reference no 11) is not?

Response:

Reviewer C Comment:

Writing requires improvement. Should conduct proofreading. The title needs improvement. The abstract should be rewritten.

Response:

The proofreading has been conducted. Herewith, I attached the certificate of proof reading

Comment:

No justification for the selection of the 3 absorbents

Response:

I have justified the selection of those adsorbents in last sentence of the first paragraph in Methodology. The justification is

…… The selection of water, waste of cooling oil and engine lubricant was based on the

availability and accessibility. Those adsorbents can be obtained freely. The selection was also based on the density and specific heat of those adsorbents as shown in Table 1. The density and specific heat of water, cooking oil, and engine lubricant were not very much differ. ………..

Comment:

It is not clear the importance of heat transfer and temperature profiles on the performance of the scrubber.

Response:

The effect of heat transfer on scrubber performance is been described in last sentence of discussion of Figure 6

…….Increasing heat transferred causes faster cooling process of the producer gas. This means that the producer gas temperature reaches condensation temperature of the tar faster, thus increasing effectiveness of the scrubbing process…….

Meanwhile, the effect of temperature difference (LMTD) on scrubber performance is mentioned

in discussion of Figure 7
